Chinese medicine says tea, are you drinking it right?

Today, I shared an article from the overseas edition of People's Daily, which featured a personal experience of drinking tea by Dr. Zhang Dong, the Chief Physician of the Cardiology Department at Xiyuan Hospital, China Academy of Chinese Medical Sciences. After reading Dr. Zhang's experience, it may challenge some of our perceptions about tea drinking. In popular belief, it has always been considered improper to drink tea on an empty stomach as it can cause discomfort, especially when drinking green tea. However, it seems that the reality is not entirely as we thought.

Taking this opportunity, I would like to share my personal experience with tea drinking. I have been a tea enthusiast for over 30 years and I have some digestive issues, including gastric ulcers and excessive stomach acid. Nevertheless, I can be called a 'tea addict.' I don't smoke or drink alcohol, but I am addicted to tea. I am the kind of person who would rather give up meat than give up tea. I remember starting to enjoy tea when I was in my teens, and my favorite is green tea. I love green tea because it is mainly produced in my hometown, which is located in the core area of China's green tea production known as the 'Golden Triangle.' The ecological environment there is exceptionally good, free from industrial pollution. Therefore, the quality of green tea is very high. Almost every household cultivates tea, which is why I have a special fondness for green tea and its refreshing aroma and taste.

I have a daily ritual of 'three brews' when it comes to drinking tea. By 'three brews,' I don't simply mean changing the water three times. The concept of 'three brews' refers to the following routine: after breakfast, I must brew a cup (or a pot) of tea. I drink the tea before starting work or while working. The second brew is in the afternoon. If I take a nap, I discard the tea leaves from the morning brew and brew a fresh cup with new tea leaves. The third brew is in the evening. I have a habit of taking a walk after dinner, usually in the park for about an hour. When I return home, I brew another cup of tea and savor it slowly. This has been my tea-drinking habit for over 30 years.

I prefer strong-tasting tea, so the tea I drink is usually concentrated. It has been like this all along. If it's too weak, I feel it lacks flavor. Also, the water temperature for brewing tea must be above 90 degrees Celsius because if the water temperature is too low, the fragrance and flavor of the tea won't be fully released. Therefore, I don't like brewing tea with low-temperature water.

In the blink of an eye, it has been over 30 years of drinking tea. I can't claim that tea is a miraculous cure-all, but I rarely get sick, not to mention serious illnesses. Even common colds are rare for me. It has been like this for decades. I haven't even used my health insurance card once. I found that my immune system is robust. Even during the COVID-19 pandemic in 2020, I didn't get infected, not even once. Isn't that surprising? I wonder if my strong immune system has anything to do with my regular tea drinking. Of course, apart from drinking tea, maintaining good lifestyle habits is also crucial.

Drinking tea does have benefits for the body, especially green tea. However, it's important to remember not to treat tea as a miraculous cure-all. We should approach it with the mindset expressed in the ancient Chinese book 'Huangdi Neijing': 'Treat before illness manifests, and regulate before disorder occurs.' Because drinking tea not only promotes health but also nurtures the mind.

The following is a forwarded article：

When I was young, I only knew of two types of tea: 'big bowl tea' and 'Biluochun' (a type of green tea). It was later, when I studied traditional Chinese medicine, that I discovered tea is also a medicinal herb. For example, Chuanxiong Tea is mentioned in the book 'Compendium of Materia Medica': 'Tea leaves have a bitter and sweet taste. They enter the Hand and Foot Shaoyin, Taiyin, and Jueyin meridians. Its function is to clear the heart and lungs, cleanse the intestines and stomach. When combined with chrysanthemum, it treats headaches; when combined with ginger, it relieves water retention and can be consumed after drinking alcohol, entering the Bladder and Kidney meridians.' However, tea is inherently cool in nature, and I have a weak and cold spleen and stomach constitution. I remember one time when I drank Pu'er tea, I had to rush to the restroom halfway through. After that, I rarely drank tea. But one chance encounter changed my perspective.

Not long ago, I was strolling around the Wudaoying Hutong near the Yonghe Temple in Beijing when I came across a small shop. The owner of the shop was a good friend of mine who invited me to try Biluochun tea. It is a type of green tea. It was dinner time, and I hesitated to drink green tea on an empty stomach. So I politely declined. But my friend said, 'Give it a try, I guarantee it won't be cooling to your body.' She explained that this tea came from an 80-year-old tea tree growing on a sunny slope in the mountains near Dongting Lake. It was the first harvest of Mingqian tea, hand-picked and processed using firewood, making it different from other green teas. Unable to resist her persuasion, I sat down and tasted this Biluochun tea. After a few cups, to my surprise, my stomach and intestines felt slightly warm and comfortable, with no signs of diarrhea. I let out a few belches and felt quite at ease, and surprisingly, I felt a sense of fullness. I stayed until 8:00 PM, drinking tea on an empty stomach without any discomfort. I even felt a slight sense of fullness and didn't feel hungry. The warm tea entered my stomach, and I started to sweat slightly, feeling incredibly comfortable. Later, my friend gave me some Biluochun tea to take home, and every time I drank it, I had the same experience. It seemed far from being a mere coincidence.

This chance encounter changed my perception of tea, especially green tea, and reminded me of an elder who once said that his father, in his nineties, had been drinking tea his whole life and lived a long and healthy life. Now I realize it's not just due to constitution. Recently, I have been pondering on this and suddenly had a realization.

Although the nature of tea is generally considered cool, whether it ultimately exhibits a cold or warm property depends largely on two factors. Firstly, the growing environment plays a role, whether it is in a predominantly yin, cold, and damp location or a warm and sunny one. Just like grapes in the north differ from those in Xinjiang, Chinese medicinal herbs such as Achyranthes bidentata, known as niuxi, have different properties in Sichuan, where it promotes blood circulation, compared to Huai niuxi in Henan, which tonifies the liver and kidneys. Another example is ginseng, with ginseng from the northeast having a warm nature, while Western ginseng tends to be cooler. These differences are primarily attributed to variations in the places of origin, which encompass factors such as temperature, sunlight, soil, and cultivation methods.

Secondly, the processing method of tea plays an equally important role. Most teas undergo a process called "kill-green," which involves using heat for fixation. Traditional Chinese medicine recognizes that the heating process can alter the cooling or warming properties of medicinal herbs. For instance, raw licorice has a cool and clearing nature, while roasted licorice has a spleen-tonifying and qi-supplementing effect. Raw Rehmannia has a cool nature that cools the blood and promotes blood circulation, while steamed Rehmannia has a slightly warm nature and tonifies the kidneys. Most herbs that undergo heating processes tend to acquire some warm properties, although the specific methods of heating, including the use of firewood or an oven, can also make a difference.

Tea processing involves various steps, many of which involve heat treatment, such as roasting or steaming. These processing techniques determine the coolness or warmth of the tea. I used to believe that fermented teas like black tea or Pu'er tea were not cooling because I didn't understand the fermentation process. Fermentation in tea production often involves spreading the tea leaves and allowing them to ferment at around 25 degrees Celsius, which is different from the heating process. Therefore, in conclusion, the coolness or warmth of tea depends on the environment and processing techniques.

From this perspective, individuals with a cold constitution can still drink green tea, while some fermented teas, such as Pu'er tea, may not be suitable. It is important to find the tea that suits oneself and understand the principle of moderation in order to find the path to health preservation.

Traditional Chinese medicine talks about tea, have you been drinking it correctly?

When I was young, I only knew of two types of tea: "big bowl tea" and "Biluochun" tea. Later, I learned about tea because of studying traditional Chinese medicine and discovering that tea is also a type of medicine. For example, the Chuanxiong tea blend is recorded in the "Essentials of Materia Medica": "Tea leaves have a bitter and sweet taste. They enter the Hand and Foot Shaoyin, Taiyin, and Jueyin meridians. They are effective in clearing the heart and lungs, purging the intestines and stomach. When combined with chamomile, it can treat headaches; when combined with ginger, it can relieve water retention and stimulate the bladder and kidney meridians when consumed after drinking alcohol." However, tea is ultimately cold in nature, and since my body constitution is weak and cold in the spleen and stomach, I remember drinking Pu-erh tea once and having to go to the bathroom halfway through, so I rarely drink tea. But one chance encounter changed my perspective.

Recently, I went to visit a small shop near the Wudaoying Hutong next to the Beijing Yonghegong Temple. The shop owner is a good friend of mine who invited me to try Biluochun tea. This is a type of green tea, and at the time it was dinner time, so how could I dare to drink green tea on an empty stomach? So I politely declined. But my friend said, "Just take a sip, I guarantee it won't be too cold." She said that this tea comes from an 80-year-old tea tree growing on a sunny mountain in Dongting Lake. This is the first crop of early spring tea picked by hand and processed with firewood, so it is not like other green teas. Unable to resist her persuasion, I sat down and tasted the Biluochun tea. After drinking a few cups, I was surprised to find that my stomach and intestines felt slightly warm and comfortable, with no signs of diarrhea. I let out a few belches and felt quite comfortable, and even had a slight feeling of fullness. I stayed until 8pm, drinking the tea on an empty stomach, without any discomfort, and even feeling slightly full without hunger. The warm tea entered my stomach and I broke out into a light sweat, feeling very comfortable. Later, my friend gave me some Biluochun tea, and every time I drank it, I felt the same way, so it seems to be no coincidence.

This chance encounter changed my understanding of tea, especially green tea, and reminded me of an elderly person who once said that his father, who was over ninety years old, had been drinking tea his whole life and lived a long and healthy life, as did many other elderly people. At first, I thought it was due to their physical constitution, but now I see it's not entirely the case. Recently, I've been thinking carefully and have had some realizations.

Although the nature of tea is generally cool, ultimately its temperature can be influenced by two factors: first, the growth environment, whether it is in a relatively yin, cold, and humid area or a warm and sunny one. Just like the difference between grapes grown in the north of China and those grown in Xinjiang, or the difference between two types of Chinese medicinal herbs called niuxi: Sichuan niuxi promotes blood circulation, while Henan niuxi nourishes the liver and kidneys. Similarly, ginseng grown in the northeast is warm in nature, while American ginseng is cooler. These differences in nature are due to their different growing environments, including temperature, sunlight, soil, and planting methods.

Second, the processing methods are also important. Most teas need to be withered and then undergo a process called "kill-green," which involves roasting with fire. Traditional Chinese medicine believes that medicinal herbs and raw herbs that have been processed by fire have different cold, hot, warm, or cool properties. For example, raw licorice has a cold and cool nature that can clear away heat and detoxify, while roasted licorice can tonify the spleen and supplement qi. Raw rehmannia has a cool nature that can cool and activate blood, while steamed rehmannia has a slightly warm nature that can nourish the kidneys. Most herbs that have been processed by fire tend to have some warm properties, depending on the specific method of fire processing, which can even vary between using firewood or an oven.

There are many steps involved in tea processing, and many of them involve using fire, either by roasting or steaming. The tea processing method determines the warmth or coolness of the tea. I used to think that fermented teas, such as black tea and Pu-erh tea, were not cool, but that was because I didn't understand the fermentation process of tea. Tea fermentation is usually done by spreading the tea leaves flat and letting them sit at room temperature of around 25 degrees Celsius, so it's different from using fire. Therefore, to sum up, the warmth or coolness of tea depends on the environment and processing method.

In light of this, people with a cold constitution are not necessarily unable to drink green tea, while some fermented teas, such as Pu-erh tea, may not be suitable. Therefore, finding the right tea for oneself and knowing the principle of moderation is the key to health.

When drinking green tea, it is better to drink Mingqian tea

Mingqian tea" is a traditional Chinese famous tea, also known as "Qingming tea", "spring tea" or "Yipian Chun". It refers to tea leaves picked before and around the Qingming Festival (around April 5th on the Gregorian calendar), usually referring to green tea or yellow tea.

"Mingqian tea" is highly regarded due to its high quality. The pleasant weather during the Qingming period, with a large difference in temperature between day and night, results in slow growth of the tea leaves, which are tender and green, with a fresh aroma and a refreshing taste, making it a "spring delicacy".

Furthermore, Mingqian tea is considered one of the purest teas because the low temperature during the harvesting season means there are no pests or diseases, which reduces the need for pesticide use in the tea garden. Therefore, compared to tea leaves picked in other seasons, the quality of Mingqian tea is superior, with a more pure taste. Since the tea leaves are harvested when they are still tender, the resulting tea has a delicate and clear green color, a rich fragrance, and a fresh and refreshing taste, making it particularly popular among tea enthusiasts.

"Mingqian tea" is mainly produced in the Jiangsu and Zhejiang regions of China, with Hangzhou's West Lake Longjing tea being the most famous. In addition to Longjing tea, there are various types of Mingqian tea, such as Huangshan Maofeng from Anhui, Qian Dao Yin Zhen, and so on.

"Mingqian tea" has an important position in Chinese tea culture and is considered a high-end gift.

Note: "Qingming" is one of the traditional 24 solar terms in China, falling on April 4th or 5th on the Gregorian calendar, which is the 15th day after the spring equinox. In ancient China, the 24 solar terms were used to guide agricultural production and daily life rhythms, and the Qingming solar term marks the mid-spring season when the temperature gradually rises, and all things grow rapidly, making it a critical time for agricultural production. In addition to Qingming, the 24 solar terms also include the Beginning of Spring, Rain Water, Waking of Insects, Vernal Equinox, Grain Rain, Beginning of Summer, Grain Full, Grain in Beard, Summer Solstice, Slight Heat, Great Heat, Beginning of Autumn, End of Heat, White Dew, Autumnal Equinox, Cold Dew, Frost's Descent, Beginning of Winter, Minor Snow, Major Snow, Winter Solstice, Minor Cold, and Major Cold.

Drinking tea can lower the risk of cardiovascular disease

People often say that drinking tea is good for your health and can reduce the risk of cardiovascular disease because of the beneficial effects of tea polyphenols on the body. But is there scientific evidence to support this claim? Tian Ying, Chief Physician of the Department of Cardiovascular Medicine at Beijing's Tiantan Hospital affiliated with Capital Medical University, will provide insight on this topic.

Does drinking tea really help reduce the risk of cardiovascular disease?

Yes, it has scientific basis. A study published in the Journal of the American Heart Association (JAHA) found that drinking tea can help reduce the risk of cardiovascular disease.

The study analyzed the relationship between changes in high-density lipoprotein cholesterol (HDL-C) levels in the blood of over 80,000 Chinese people and tea consumption over a six-year follow-up period.

The results showed that people who regularly drank tea had a slower decline in HDL-C levels and an 8% lower risk of cardiovascular disease. HDL-C is a "good cholesterol" that corresponds to "bad cholesterol" - LDL-C. LDL-C is easily deposited on the walls of blood vessels, causing atherosclerosis, while HDL-C has a protective effect on blood vessels.

In fact, this is all due to the action of tea polyphenols. Tea polyphenols are antioxidants that can be anti-inflammatory, change the viscosity of blood, reduce blood lipids, make blood vessels more elastic, prevent microvascular rupture, and long-term consumption can make the heart and blood vessels healthier, reducing blood lipids and preventing cardiovascular disease.

How to drink tea for cardiovascular health?

Green tea: Green tea has a higher content of tea polyphenols and can slightly lower the risk of cardiovascular disease in women.

Oolong tea: Oolong tea can lower the risk of cardiovascular disease in men more, and older people who drink tea regularly can greatly reduce the risk of cardiovascular disease mortality.

To achieve the preventive effect of cardiovascular disease, you should drink at least 3-4 cups per day, with each cup being 220-230 milliliters, and drink at least 4-5 times a week. Do not drink too much at one time, but drink tea continuously in small amounts every day.

Note: Drinking tea cannot replace the role of medication. It is only a method to assist in making our body healthier. If you have cardiovascular disease, you should still seek treatment from a specialized doctor in a hospital.

8 types of tea that should not be consumed:

1.Strong tea: Overly strong tea can cause discomfort to the heart because tea leaves contain caffeine, theophylline, and other substances. Also, if you drink a lot of strong tea, the tannic acid in it will react with the iron in food to form insoluble substances that will hinder iron absorption.

2.Moldy tea: Tea leaves become moldy due to contamination by microorganisms such as Aspergillus and Penicillium. The tea brewed from moldy tea leaves has no tea aroma and can cause harm to the human body, such as causing dizziness and diarrhea. Moldy tea leaves generally have white mold spots on the surface and smell damp and musty, especially when brewing. Tea leaves should be stored in a dry place to prevent mold.

3.Tea with odors: Tea leaves contain terpenes, which are porous and easily absorb odors from other things. Some odors may contain toxins, such as the odor of paint and camphor, which can harm the human body. Tea leaves should be stored separately from odorous foods.

4.Over-brewed tea: Brewing tea for too long not only gives tea a dark color and poor taste but also reduces the nutritional value of the tea due to the oxidation of vitamins and amino acids in the tea leaves. In addition, tea that has been left for too long is easily contaminated by microorganisms in the environment, making it unhygienic.

5.Raw tea: Raw tea refers to unrolled green tea leaves that are dried directly after withering. This type of tea has the same components as fresh leaves and has a strong raw green flavor. Elderly people who drink this type of tea are very likely to experience stomach pain due to its strong irritation to the stomach mucosa. Young people may also feel discomfort in the stomach after drinking it, commonly known as "stomach scraping." Raw tea should not be brewed directly. Instead, it can be put in an oil-free iron pan and slowly roasted over low heat to remove the raw green flavor. It can be consumed after a slight roast fragrance is produced.

6.Overheated tea: Tea is generally brewed with boiling water, but it should not be consumed when it is too hot. Otherwise, it may burn the mucous membranes of the mouth and esophagus, causing ulcers. Over time, it may induce oral or esophageal cancer.

7.Burnt tea: If tea leaves are over-roasted during the production process, they will produce a burnt flavor. This type of tea has fewer effective nutrients and the components that determine the taste of the tea are destroyed to a greater extent. It may also contain certain carcinogens.

8.Overnight tea: Overnight tea contains trace amounts of amino acids, sugars, and other nutrients that become nutrients for bacteria and mold to grow. In addition, various nutrients such as tea polyphenols and vitamins inthe tea will be oxidized and decomposed, reducing the nutritional value of the tea. Drinking overnight tea is not recommended because it may cause gastrointestinal discomfort and increase the risk of bacterial infections. It is best to prepare fresh tea each time you want to drink it.

Tips for drinking tea:

1.Long-term tea consumption can help reduce the risk of cardiovascular disease.

2.Drink at least 3-4 cups of tea per day, with each cup being 220-230 milliliters, and drink at least 4-5 times a week.

3.Drinking tea cannot replace the role of medication.

4.These 8 types of tea are best avoided: strong tea, moldy tea, tea with odors, over-brewed tea, raw tea, overheated tea, burnt tea, and overnight tea.

Staying Away from "Three Highs", Drinking Tea is a Simple and Effective Feasible Method

What is "Three Highs"?

"Three Highs" refers to hypertension, hyperlipidemia, and hyperglycemia, also known as "Three Highs Syndrome". Hypertension is a disease in which blood pressure continues to rise beyond the normal range; hyperlipidemia is a condition in which the fat content in the blood exceeds the normal range, including cholesterol and triglycerides; hyperglycemia is a disease in which blood sugar levels continue to rise beyond the normal range. These three diseases are related to factors such as lifestyle, diet, and genetics. If not controlled for a long time, they can seriously affect human health, and even lead to the occurrence of cardiovascular and cerebrovascular diseases, diabetes, and other serious illnesses. Therefore, it is very important to prevent and control "Three Highs Syndrome". The disease can be controlled by reasonable diet, moderate exercise, quitting smoking, and limiting alcohol consumption, and early detection and treatment of the disease. By adopting scientific and reasonable diet, moderate exercise, quitting smoking, and limiting alcohol consumption, we can effectively reduce the harm of "Three Highs Syndrome" and protect human health.

So, how can "Three Highs" be effectively controlled? A simple method is to drink tea!

Drinking tea can really reduce the risk of "Three Highs":

Reducing the risk of diabetes

In 2021, Professor Li Liming from Peking University School of Public Health and others analyzed the data of more than 500,000 adults in China's chronic disease prospective study and found that daily consumption of green tea can prevent type 2 diabetes in the general population, while regular consumption of green tea can significantly reduce the risk of death among people with diabetes. (1)

Lowering the risk of hypertension

In 2014, a cohort study conducted in China investigated the relationship between tea consumption and blood pressure changes in 1,109 participants over a five-year period. The results showed that there was a strong interaction between increased green tea intake and decreased diastolic blood pressure. Compared with non-tea drinkers, those who consumed a total of ≥10 grams of green tea per day had a smaller increase in diastolic blood pressure. (2)

Improving blood lipid abnormalities

A cross-sectional study published in 2017 showed that people who drank more than 30 cups of tea per week for more than six months had lower levels of low-density lipoprotein cholesterol in their serum, and higher levels of total cholesterol and high-density lipoprotein. (3)

Dr. Wang Fang, director of the cardiology department at Beijing Hospital, also wrote in a 2018 article in the Health Times that Pu-erh tea, as well as other types of tea, contain various substances such as tea polyphenols, tea pigments, tea polysaccharides, and caffeine, which to some extent can regulate lipid metabolism, glucose metabolism, blood rheological properties, and vascular elasticity. Therefore, drinking Pu-erh tea can play a preventive role in high blood lipids, high blood sugar, thrombosis, and various factors that cause heart and brain damage. However, for patients with pre-existing diseases, drinking tea alone is not enough, and medication such as lipid-lowering drugs, hypoglycemic drugs, and blood vessel unblocking drugs is still necessary. (4)

6 Things to Keep in Mind When Drinking Tea!

Don't drink strong tea

Chen Hong, deputy chief physician of the Chinese medicine department at Wuhan Donghu Hospital in Hubei Province, said in an interview with Changjiang Daily in July 2022 that everything should be done in moderation, and drinking light tea can promote health, while drinking strong tea can harm health. For example, elderly people with weak gastrointestinal function may experience discomfort from drinking large amounts of strong tea for a long time. Strong tea contains caffeine, and excessive consumption of strong tea can cause dizziness, headaches, and increase the burden on the heart, leading to uncomfortable symptoms such as chest tightness and palpitations, and causing high blood pressure. (5)

Don't drink tea on an empty stomach

Qian Duoduo, a member of the Capital Health and Nutrition Gourmet Society, reminded in an article in the Health Times in 2019 that tea, especially green tea, has high levels of tea polyphenols and caffeine. If consumed on an empty stomach, some of the active substances will combine with the protein in the stomach, causing irritation to the stomach, which can easily lead to stomach discomfort and even "drunk tea" symptoms such as dizziness. Especially for people with poor gastrointestinal function, it is not recommended to drink green tea. (6)

Don't drink tea too late

Tea has a refreshing and diureticeffect. Drinking a cup of light tea in the morning can help refresh the mind. For people who have trouble sleeping, it is not recommended to drink tea in the evening to avoid causing insomnia.

Don't drink tea that is too hot

Drinking tea that is too hot may burn the esophageal mucosa and increase the risk of esophageal and gastric cancer. Therefore, after brewing tea with hot water, let it cool down before drinking it. Li Shujun, chief physician of the Department of Gastroenterology at Beijing Tsinghua Chang Gung Hospital, said in an interview with the Health Times in 2019 that the surface of the esophagus is covered with delicate mucosa, and food temperature has a great impact on it: 10℃ to 40℃ is the most suitable, while 50℃ to 60℃ can barely be tolerated, and temperatures above 65℃ can cause burns. Don't think that 65℃ is a low temperature, as a hot dumpling can easily exceed this temperature. (7)

Drink tea one hour after meals

Zhang Xiaoyan, chief physician of the nutrition department at Lianyungang Maternal and Child Health Hospital in Jiangsu Province, said in an article in the Health Times in 2017 that it is not advisable to drink tea immediately after a meal, and it is best to drink tea one hour after a meal. This is because tannic acid in tea can inhibit the secretion of gastric and intestinal fluids, leading to digestive problems. Moreover, tannic acid can combine with proteins to form astringent protein, which weakens intestinal motility and can lead to dry stools. More importantly, tea can interfere with the absorption of iron by the body. (8)

Don't drink tea when taking certain medications

Wang Yali, a pharmacist at Beijing Hepingli Hospital, reminded in an article in the Health Times in 2023 that anemic patients taking iron-containing drugs, people taking Chinese medicine with alkaloids as the main component, such as ephedra, coptis, phellodendron, and pulsatilla, people taking tonifying Chinese medicine, such as Codonopsis pilosula, astragalus, polygonum multiflorum, and psoralea, people with palpitations, insomnia, and vivid dreams taking tranquilizers, and people with spleen and stomach diseases, especially those with active peptic ulcers, should not drinktea.

The premium Longjing tea is flat, smooth and straight, the color is green and smooth, the aroma is fresh and high, the taste is fresh and sweet, and the bottom of the leaves is delicate and blooming. In 2001, the State Administration of Quality Supervision officially approved "Longjing tea" as a protected product in the area of origin.

Longjing tea features: Longjing tea is unique in the world for its green color, beautiful shape, fragrant and mellow taste. It ranks first among the top ten famous teas in China. The premium Longjing tea is flat, smooth and straight, the color is green and smooth, the aroma is fresh and high, the taste is fresh and sweet, and the bottom of the leaves is delicate and blooming.

Historical Origins: Before the Sui and Tang Dynasties, Hangzhou tea culture was in the rising stage. During the Three Kingdoms and Jin Dynasties, the economy and culture on both sides of the Qiantang River gradually developed, Lingyin Temple was built, and religious activities such as Buddhism and Taoism gradually became popular. After the opening of the Beijing-Hangzhou Grand Canal in the Sui Dynasty, Hangzhou, due to the geographical convenience of water and land transportation, became a "rich and famous city" in the southeast where products gathered and scattered. At this time, tea was widely cultivated in Hangzhou. During the Northern Song Dynasty, the Longjing tea area had initially formed a scale. At that time, the "Xianglin Tea" from Xiatianzhu Xianglin Cave in Lingyin, the "Baiyun Tea" from Baiyun Peak in Shangtianzhu, and the "Baoyun Tea" from Geling Baoyun Mountain were listed as tribute. During the Jiajing period of the Ming Dynasty, there was a record that "the tea in Hangzhou County is not as good as the production of Longjing, and the fine buds before the rain, whichever is a flag and a gun, are especially treasures". In the Yuan Dynasty, Longjing tea had a good reputation. Yu Ji, a tea lover, wrote a tea drinking poem "You Longjing". In the poem, "Wandering on the Longjing, the clouds are clear. The golden buds are fried, and the three swallows can't bear to rinse." widely sung. In the Qing Dynasty, Emperor Qianlong went to Jiangnan six times, and went to Longjing four times. He wrote six imperial poems about Longjing tea, and he personally named "Eighteen Royal Tea Trees", raising Longjing tea to the supreme status. After the Republic of China, Longjing tea gradually became the first famous tea in China.

The efficacy of Longjing tea: 1. Exciting effect: The caffeine in tea can excite the central nervous system, help people to invigorate their spirits, improve their thinking, eliminate fatigue and improve work efficiency. 2. Diuretic effect: The caffeine and theophylline in tea have diuretic effect and are used to treat edema and water stagnation. The detoxification and diuretic effects of black tea and sugar water can be used to treat acute jaundice hepatitis. 3. Strengthen the heart and relieve spasm: Caffeine has the effect of strengthening the heart, relieving spasm and relaxing smooth muscle, can relieve bronchospasm and promote blood circulation. It is a good auxiliary drug for the treatment of bronchial asthma, cough and phlegm, and myocardial infarction. 4. Inhibition of arteriosclerosis: Tea polyphenols and vitamin C in tea have the effect of promoting blood circulation and removing blood stasis to prevent arteriosclerosis. Therefore, among people who drink tea regularly, the incidence of hypertension and coronary heart disease is lower. 5. Antibacterial and antibacterial effects: The tea polyphenols and tannic acid in tea act on bacteria, which can solidify the protein of bacteria and kill bacteria. It can be used to treat intestinal diseases, such as cholera, typhoid, dysentery, enteritis, etc. If the skin is sore, festering and oozing pus, and the skin is broken by trauma, rinse the affected area with strong tea, which has anti-inflammatory and bactericidal effects. Oral inflammation, ulceration, and sore throat can also be treated with tea. 6. Weight loss effect: Various compounds such as caffeine, inositol, folic acid, pantothenic acid and aromatic substances in tea can regulate fat metabolism, especially oolong tea has a good decomposition effect on protein and fat. Tea polyphenols and vitamin C can reduce cholesterol and blood lipids, so drinking tea can lose weight. 7. Anti-caries effect: tea contains fluorine, fluoride ion has a great affinity with the calcium of teeth, and can become a kind of "fluorapatite" which is more insoluble in acid, just like adding a protection to teeth layer, which improves the ability of teeth to resist acid and caries. 8. Inhibition of cancer cells: According to reports, the flavonoids in tea have different degrees of anti-cancer effects in vitro, and vitexine, morin and catechin have stronger effects. 9. The effect of promoting body fluid and quenching thirst, refreshing and improving thinking, digestion and greasy, anti-inflammatory and detoxification. 10. The antioxidant effect is because tea has antioxidant, anti-tumor, and lower blood cholesterol and low-density lipoprotein content, inhibits blood pressure, inhibits platelet aggregation, antibacterial, and anti-allergic products. 11. Longjing green tea contains more chlorophyll, amino acids, catechins, and vitamin C than other teas. It is rich in nutrients, and has the functions of quenching thirst, refreshing, quenching thirst, and reducing neutral fat and cholesterol in the blood. It has anti-oxidation, anti-sudden mutation, anti-tumor, lowering blood cholesterol and low-density lipoprotein content, inhibiting blood pressure rise, inhibiting platelet aggregation, antibacterial, anti-allergy and other effects. If it is brewed with Hangzhou Hupao spring water, the fragrance is clear and the taste is crisp, and it is known as the "double must" of Hangzhou.

Tea farmers are picking spring tea. For green tea, the quality of spring tea is the best, so if you want to drink tea, it is better to drink spring tea. The benefits of spring tea are as follows: 1. The nutrient accumulation of spring tea is the thickest. In autumn and winter, organisms are in a state of accumulation and storage. While spring tea is recuperating, it stores abundant energy. In addition, the temperature in spring continues to maintain a low temperature state, and the consumption is very small, which makes the nutrients in the body of the spring tea more abundant, and the appearance of the buds and leaves is plump, the color is green, and the leaves are soft. 2. The aroma of spring tea is fragrant and long-lasting. Flowers are "live" because of their fragrance, and tea is "expensive" because of their fragrance. Just bid farewell to the early spring of winter, the temperature is not high, and the aroma substances are preserved in a good environment, so the aroma of spring tea is incomparable to other seasons of tea. 3. The taste of spring tea is the most fresh. The sunshine in spring is not too strong, the temperature is low, and the cell formation of tea buds is relatively slow, which accumulates a large amount of amino acids, and the content of amino acids makes spring tea different from other seasons. Cool taste. 4. The external pollution of spring tea is basically zero. Because of the severe cold in winter, the tea trees are free from pests and diseases. When the tea buds germinate in spring, there is no need to apply pesticides, and the tea leaves are free of pollution and pesticide residues.

New Study Finds: Green Tea Extract Promotes Gut Health, Lowers Blood Sugar

New research in people with a range of heart disease risk factors shows that drinking green tea extract for four weeks can lower blood sugar levels and improve gut health by lowering inflammation and reducing "leaky gut." The research was recently published in "Recent Developments in Nutrition."

The researchers say this is the first study to assess whether the health risks associated with metabolic syndrome are reduced by the anti-inflammatory effects of green tea in the gut. Metabolic syndrome affects about one-third of Americans.

"There is a lot of evidence that high consumption of green tea is associated with good levels of cholesterol, glucose, and triglycerides, but no studies link green tea's gut benefits to these health benefits," said senior study author Richard Bruno, professor of human nutrition at The Ohio State University. factors are linked.”.

The team conducted the clinical trial in 40 individuals as a follow-up to a 2019 study that showed that mice consuming green tea supplements had lower rates of obesity, lower health risks and improved gut health.

In the new study, green tea extract also lowered blood sugar, reduced gut inflammation and permeability in healthy people, an unexpected finding.

"This tells us that, within a month, we were able to lower blood sugar in both metabolic syndrome patients and healthy people, and that lowering blood sugar appears to be associated with a reduction in leaky gut and inflammation, regardless of health status," Bruno said.

People with metabolic syndrome have been diagnosed with at least three of five factors that increase their risk of heart disease, diabetes and other health problems - excess belly fat, high blood pressure, low HDL (good) cholesterol, fasting blood sugar and high levels of triglycerides (a type of fat in the blood).

The tricky thing about these risk factors for metabolic syndrome, Bruno says, is that they're often only slightly altered, don't yet require drug management, but still pose a significant risk to health.

"Most doctors will initially recommend weight loss and exercise, but most people can't make lifestyle changes for a variety of reasons," Bruno said. "Our work aims to provide people with a new food-based tool to help them manage their metabolism. Syndromic risk or reversal of metabolic syndrome."

Forty participants, including 21 with metabolic syndrome and 19 healthy adults, consumed gummies containing green tea extract, which is rich in anti-inflammatory compounds called catechins, for 28 days. The daily dose is equivalent to five cups of green tea. In the randomized double-blind crossover trial, all participants took a placebo for 28 days, with one month stopping any supplements between treatments.

The researchers confirmed that during the placebo and green tea extract dessert study phases, the participants were advised to have a diet lower in polyphenols (antioxidants found naturally in fruits, vegetables, tea and spices), so any results could be attributable to on the influence of green tea itself.

The results showed that all participants had significantly lower fasting blood sugar levels after taking green tea extract compared to blood sugar levels after taking a placebo. The analysis found that all participants had reduced intestinal inflammation with green tea treatment and reduced pro-inflammatory proteins in their stool samples. The researchers also found that after drinking green tea, the participants' small intestine permeability decreased significantly.

Gut permeability, or leaky gut, allows gut bacteria and related toxic compounds to enter the bloodstream, stimulating low-grade chronic inflammation.

"We're not trying to cure metabolic syndrome with a one-month study," he said. "But based on what we know about the causal factors behind metabolic syndrome, green tea has the potential to play a part at the gut level to reduce the risk of developing or reversing metabolic syndrome."

Bruno's lab is completing further analyses of the study participants' gut microbiomes and levels of bacteria-related toxins in their blood.

Another miracle of green tea! Jinan University researchers find green tea has anti-coronavirus properties, including mutants

The production and consumption of tea has a history of more than 4,000 years. At present, more than 2 billion cups of tea are consumed every day in the world, which is second only to water in terms of global consumption. Previously published research has shown that regular consumption of green tea and coffee has health benefits because these beverages contain a variety of bioactive compounds. However, little is known about green tea's antiviral properties.

On March 17, 2021, a study by researchers at Jinan University on the bioRxiv preprint platform reports that green tea has antiviral activity, adding to its long-term health benefits. In the new study, epigallocatechin gallate (EGCG), one of the components of green tea, prevented severe SARS-CoV-2 from binding to the human angiotensin-converting enzyme 2 (ACE2) receptor, thereby preventing infection in humans lung cells, and inhibitory effects were also observed in SARS-CoV-2 variants.

The main active ingredients in green tea are catechins, including epigallocatechin gallate (EGCG), epigallocatechin (EGC), epigallocatechin gallate (ECG), and epigallocatechin (EC), of which EGCG is the most abundant catechin in green tea.

The researchers created several pseudoviruses containing complete mutations (B.1.1.7, B.1.351 and B.1.429) with single mutations (K417N, E484K, N501Y, D614G) or emerging variants. S protein, and pseudoviruses were then transfected into HEK293T-hACE2 cells.

Through experiments, the researchers found that green tea effectively prevented the infection of wild-type, D614G, B.1.429 and B.1.351 in a dose-dependent manner.

The researchers also found that when tested against HCoV OC43 in HCT-8 cells, green tea beverages were also observed to protect against infection by other coronaviruses.

Next, the researchers looked for the substances in green tea that cause these antiviral effects. The active components of green tea catechins EGCG, EGC, ECG and EC were studied.

The results showed that three catechins: EGCG, EGC and ECG dose-dependently blocked pseudovirus infection caused by the wild-type SARS-CoV-2 strain.

Upon closer inspection, the researchers concluded that EGCG was the most potent inhibitor of viral infection. EGCG accounts for more than 50% of the catechins in green tea beverages.

Then, after exposure of EGCG to mutants such as D614G, K417N, E484K and N501Y, its ability to cause infection was also inhibited.

The researchers also found that EGCG inhibited viral infection of cells containing interesting variants, including B.1.17, B.1.351 and B.1.429.

Testing EGCG on infected human lung epithelial cells, the researchers found that it inhibited SARS-CoV-2 before and after infection. However, the inhibitory activity was greater when cells were pretreated with EGCG prior to SARS-CoV-2 infection.

Further studies identified the mechanism of action of EGCG against SARS-CoV-2, and the researchers found that it blocked the entry of the virus by blocking the S1 subunit with the highest binding affinity with ACE2. EGCG also reduced the binding of the S2 subunit, although it had little binding affinity to ACE2.

In conclusion, studies suggest that consumption of green tea or its active ingredient EGCG may help prevent or reduce the spread and infection of SARS-CoV-2, given its low toxicity, anti-inflammatory, antioxidant and anti-SARS-CoV-2 variant properties, drinking Green tea may minimize the spread of SARS-CoV-2 and improve symptoms and disease severity.

What are the health benefits of drinking tea?

Tea is one of the most popular beverages in the world. Tea is rich in micronutrients, including fluoride, magnesium ions, and zinc ions. However, its health benefits are mainly related to three main bioactive compounds. Including catechols, caffeine and L-theanine, tea consumption is often associated with many health benefits, which can help improve mood and cognition, and reduce an individual's risk of cardiovascular disease and diabetes. In this article, the editor took stock of the relationship between drinking tea and the health benefits of the body, and shared it with you! 【1】：Drinking tea can induce epigenetic changes in female body Epigenetic changes are chemical modifications that help turn on/off gene expression. In a recent study published in the international journal Human Molecular Genetics, researchers from Uppsala University in Sweden found that , Tea drinking in women may induce epigenetic changes in specific genes that are thought to interact with cancer and estrogen metabolism. We all know that our living environment and lifestyle, such as food choices, smoking, and exposure to chemicals, can lead to epigenetic changes; in this study, the researchers investigated whether drinking tea and coffee Can trigger epigenetic changes, previous research has shown that coffee and tea play a key role in regulating human disease risk, such as inhibiting tumor progression, reducing inflammation and affecting estrogen metabolism, and the mechanisms may all be through epigenetic mediated by genetic changes. The findings suggest that epigenetic changes occur in tea-drinking women, but not in men. Even more interesting, many epigenetic changes tend to occur in genes involved in cancer and estrogen metabolism. Previous research has shown that drinking tea can reduce estrogen levels in the body, and this clarifies the difference in the biological response of men and women to drinking tea. The researchers pointed out that women tend to drink more than men. Plenty of tea, which also increases our chances of finding a connection between tea drinking and women. Of course, this study did not find any epigenetic changes in coffee-drinking individuals. 【2】Drinking tea reduces mortality, is it true? Professor Nicolas Danchin from France presented a study involving 131,000 people at the annual meeting of the European Heart Association on August 31. The study revealed that tea drinking reduced non-cardiovascular mortality by 24%. Professor Tang Shan said: "If you have to choose between tea and coffee, it's probably better to drink tea. Both coffee and tea are an important part of our lifestyle. Their impact on cardiovascular (CV) health is Studies have been done in the past, sometimes with conflicting results. We looked at the effects of coffee and tea on CV-factor mortality and non-CV-factors in a large cohort of French people with a lower risk of cardiovascular disease. Mortality impact." The study involved 131,401 people, aged 18 to 95, who had undergone medical examinations at the Centre for Preventive Medicine at the Free School of Philosophy and Psychology in Paris between January 2001 and December 2008. Over the next average of 3.5 years, there were 95 deaths from CV causes and 632 deaths from non-CV causes. Coffee or tea consumption was divided into three levels on the self-help questionnaire: none, 1-4 cups per day, and 4 or more cups per day. [3] Take a break, drink a cup of tea, drink a cup of coffee, you can also prevent liver disease Cirrhosis, or chronic liver disease, is a serious condition that has become the leading cause of death across the United States. To prevent liver disease, a new study recommends taking a break and enjoying a good cup of tea. Liver disease-related deaths are often the result of cirrhosis. Although the vast majority of cases of cirrhosis in people are caused by chronic alcohol consumption, nonalcoholic fatty liver disease (NAFLD) can also lead to cirrhosis. The latest study, published in the Journal of Hepatology, adds a new set of preventive factors: tea and coffee. Scientists led by Dr. Sarwa Darwish Murad, a liver specialist at the Erasmus University Medical Center in Rotterdam, the Netherlands, set out to study the effects of drinking tea and coffee on liver health. 【4】IJC: Regular consumption of coffee and tea reduces the risk of endometrial cancer A new study by American scientists shows that women who drink coffee and tea regularly can reduce the risk of endometrial cancer. Scientists at the Roswell Park Cancer Institute reported in the April issue of the International Journal of Cancer that they tracked nearly 1,100 women and found that those who drink coffee and tea regularly People had a lower risk of developing endometrial cancer than non-drinkers, and the more coffee and tea they drank, the lower their risk of developing this cancer. Those who drank more than 4 cups of coffee or tea a day had a roughly 50 percent lower risk of endometrial cancer than those who didn't, the report said. Those who drank an average of 2 cups of tea or coffee a day had a 44% and 29% lower risk of developing this cancer than those who did not drink it. 【5】Which tea is most beneficial to the health of the body? News reading: What science says about getting the most out of your tea Tea is one of the most popular beverages in the world. Of course, tea is also a matter of personal preference; everyone's preference for tea is different, so what does the scientific community say about it? Drinking tea is often associated with a number of health benefits, which can help improve mood and cognition, and reduce an individual's risk of cardiovascular disease and diabetes. Tea is also rich in micronutrients, including fluoride, magnesium ions, and zinc ions, but the health benefits shown are primarily related to three major bioactive compounds, including catechol, caffeine, and L-Theanine, a bioactive compound is a non-essential nutrient that can affect the health of the body. Laboratory and animal studies have shown that these bioactive compounds can have a variety of health effects, but the results of research in humans are unclear; catechol is a polyphenol, and polyphenols It is a class of natural compounds with antioxidant properties. Antioxidants can inhibit cell damage in the body. Caffeine can make the body alert. At the same time, the amino acid L-theanine is believed to relax people. These bioactive compounds will make us experience To the brewed taste and texture. [6] Population study suggests a cup of tea a day may improve heart health Original report: A daily cup of tea may soothe your heart A new study recently found that a cup of tea a day may be good for heart health. The study found that people who drank a cup of tea a day were 35 percent less likely to develop heart failure or other major cardiovascular disease than those who didn't drink tea. The study also found that tea drinkers also had a lower risk of calcification in the coronary arteries of the heart, which the researchers said was associated with heart disease, stroke and other serious diseases. Dr. Elliott Miller of Johns Hopkins said: "We found that people who drank tea moderately had slower progression of coronary calcification and a lower risk of cardiovascular events." But Miller also pointed out that they haven't been able to prove whether there is a causal relationship between tea drinking and heart disease risk. "This is just an observational study, and we can't say for sure whether it's the tea itself or the people who drink it that have healthier lifestyle habits that lead to a lower risk of cardiovascular disease." For the study, Miller and his research team analyzed data from a study that began in 2000 and is still ongoing, with more than 6,000 participants, both men and women. When the study started, none of the participants had heart disease. [7]: Green tea is not only healthy, it can also be used to treat cancer in the future Scientists in Singapore have recently discovered that an active ingredient in green tea can serve as a potential nano-drug delivery system for delivering protein drugs to treat cancer. In animal experiments, the researchers used this antioxidant called gallic acid (EGCG) to load Roche and Genentech's breast cancer drug Herceptin. Compared with the control group, the drug-loaded system was more than twice as effective. . At the same time, after being encapsulated by the drug-loading system, the accumulation of the drug in the liver and kidney was reduced by about 70%, and the accumulation in the lung was reduced by 40%. The research has been published in the prestigious journal Nature Nanotechnology. Until recently, EGCG was only considered a beneficial component of green tea, and its drug-carrying system function was only recently discovered. The researchers combined EGCG with polyethylene glycol, allowing EGCG to protect the protein drug from degradation. Jackie Ying, who is in charge of this research, said that it is the first time to apply the active ingredients in green tea to the field of nanomedicine, and the synergistic effect of the drug and the drug delivery system also surprised the researchers. [8]: Researchers think coffee and tea may help liver health A cup of coffee or tea in the morning may be more than a booster before you work. An international team of researchers led by researchers at Duke-NUS Graduate School of Medicine and Duke University School of Medicine has suggested that increasing caffeine intake may reduce fatty liver disease in patients with nonalcoholic fatty liver disease (NAFLD). Worldwide, 70% of people with diabetes and obesity have fatty liver. An estimated 30% of American adults have the disease, and its prevalence is on the rise in Singapore. Apart from diet and exercise, there is no effective treatment to cure NAFLD. Using cell cultures and mouse models, researchers such as Paul Yen observed that caffeine stimulates the metabolism of lipids stored in liver cells and reduces fatty liver in mice fed a high-fat diet. 【9】: Green tea catechins effectively block rheumatoid arthritis ​​ Researchers from Washington State University have identified a new way to fight joint pain, inflammation and tissue damage caused by rheumatoid arthritis. The study was published in the international journal Arthritis and Rheumatology. Rheumatoid arthritis is a serious autoimmune disorder that affects the function of the small joints of the hands and feet, often causing painful bulges in the joints, which then develop into cartilage damage, bone erosion, and joint deformities. Researcher Salah-uddin Ahmed pointed out that the current treatment of rheumatoid arthritis drugs are very expensive, and have a certain degree of immunosuppression, sometimes not suitable for long-term use. The researchers evaluated a phytochemical called catechin (epigallocatechin gallate, EGCG), an anti-inflammatory molecule found in green tea, that There is great potential for the treatment of rheumatoid arthritis because the molecule can effectively block the effects of the disease without blocking the precursors of other cellular functions. [10] Another major effect of green tea: reverse liver damage Original article: Finding liver cancer early and reversing its course Liver cancer is often fatal in humans because it is often diagnosed at an advanced stage. But, in animal models, a new work has uncovered a potential diagnostic biomarker for liver cancer, as well as a potential way to reverse pre-existing liver damage. The research will be reported at the 2015 AACR Annual Meeting in Philadelphia. Dr. Ying Fu, Georgetown Lombardi Comprehensive Cancer Center, explained the new work, "Hepatocellular carcinoma, the most common type of liver cancer, is the world's most The third leading cause of cancer death." "In this work, we found in two animal models that damaged lesions of DNA (guanine) (γ-OH-Acr-dG) are associated with hepatocellular cancer. It has the potential to be an early diagnostic tool for hepatocellular cancer. Biomarkers."

The United States studies the mechanism of green tea killing cancer cells

People often hear that green tea can prevent cancer and fight cancer. What is the principle? According to Penniscus scientists, research on cancer cells and normal cells at Binzhou State University found that green tea contains a polyphenol called EGCG, which can damage mitochondria in cancer cells, triggering a chain reaction that affects cancer cells.

What's more interesting is that EGCG does not harm healthy cells and can improve the self-protection ability of healthy cells. Reporting in the journal Molecular Nutrition and Food Research, the researchers said the study showed that green tea not only kills oral cancer cells, but is also effective against other types of cancer cells, according to the researchers. They hope that after intensive research, they can produce cancer drugs that are as effective as current chemotherapy drugs but without the side effects.
