1, stand down
Old white tea is rich in tea polyphenols, which has the functions of lowering blood pressure, blood lipid and blood sugar. Drinking regularly can also prevent getting angry. Drinking regularly is good for your health.
2, prolong life
The content of flavonoids in old white tea is higher than that in other teas. Regular drinking can prolong life, especially suitable for making health tea.
3. Reduce blood sugar
Old white tea contains a lot of active enzyme components, which can increase the activity content of lipase in human body, promote fat catabolism, effectively inhibit insulin secretion, help decompose excess sugar in blood, and thus promote blood sugar balance.
Step 4 protect the liver
Old white tea is rich in flavonoids, which can accelerate the metabolism of ethanol and decompose acetaldehyde quickly, thus reducing the damage of harmful substances to liver cells.
5, heat and detoxification
Old white tea contains many nutrients, especially old white tea stored for a long time, which can drive away the cold. Heat dissipation, detoxification and other benefits, but also as a fever medicine for children with measles, the effect is excellent.
skill
Old white tea is very resistant to soaking, which can reach more than 20 times under the ordinary soaking method, and it is still very delicious after soaking several times. In addition, I personally think that old white tea can be boiled in a teapot, which fully shows its tea rhyme and essence.
The above is the introduction of the efficacy of old white tea. Through understanding, we can know that drinking old white tea often has many benefits to the body, and it is a healthy health tea.
What kind of tea is white tea
As we all know, white tea is one of the six famous teas in China. White tea is named because of its white appearance. This kind of tea is produced in Fuding, Fujian, also called Fuding white tea. White tea is a unique tea treasure in China because of its complete appearance and light and sweet taste. Because the tea tree of white tea is different from picking, it is different.
White tea is slightly cold, rich in various amino acids, and has the effects of clearing away heat, relieving summer heat and detoxifying. Drinking white tea often rarely leads to heatstroke, so white tea is an essential summer product. White tea can resist radiation and is suitable for computer families, students and office families who often deal with computers.
White tea is a specialty of Fujian, and its finished tea is mostly bud head, covered with white hair and silver as snow, which is relatively rare. White tea can be divided into bud tea such as Baihao Yinzhen and leaf tea such as Bai Mudan, Gongmei and Shoumei because of different varieties of tea trees and different standards of picking raw materials.
White tea is good for health. First, increase appetite. Children in modern families have high status, eat more snacks and refuse to eat more. Moderate consumption of white tea can help digestion and relieve boredom, increase gastrointestinal peristalsis, promote the secretion of digestive juice and increase appetite.
White tea is good for health. 2. Clear away heat and refresh your mind. Drinking some white tea properly for college entrance examination students can clear away heat and refresh themselves and improve their memory. White tea is also rich in provitamin A, which can be quickly converted into vitamin A after being absorbed by the human body, and can prevent night blindness and dry eye.
White tea is good for health. Third, prevent obesity. Drinking white tea can reduce weight, relieve fatigue, strengthen the body and prevent cardiovascular diseases.
White tea is good for health. Fourth, prevent diseases and improve immunity. White tea contains high fluorine content and can prevent dental caries; The bactericidal components in tea can prevent stomatitis, remove bad breath, supplement the deficiency of vitamin C and prevent gum bleeding; Carotene in tea can be metabolized into rhodopsin to protect eyesight. From the perspective of traditional medicine, white tea also has the function of clearing fire, which can "clear the leader, eliminate stagnation and benefit both sides."
White tea is good for health. 5. excrete toxins. Modern children interact with TV sets and game machines. Electronic radiation and environmental pollution are harmful to children's healthy growth. Tea polyphenols and lipopolysaccharide in white tea can adsorb and capture radioactive substances, and then excrete them after combining with them, which also has an early preventive effect on some cancers.
The efficacy of white tea has the health-care effects of anti-radiation, anti-oxidation and anti-tumor (lowering blood pressure, blood lipid and blood sugar), and also has the health-care effects of nourishing heart, liver, eyes, qi and beauty.
The production process of white tea is very special and the most natural way. Do not stir-fry or knead, do not prevent the oxidation of tea polyphenols like green tea, nor promote its oxidation like black tea. Instead, the collected fresh tea leaves are spread thinly on bamboo mats, placed in weak light or in a room with good ventilation and light transmission effect, and let them wither naturally.
When it is 70% to 80% dry, it can be dried slowly with slow fire. Because of the simple manufacturing process and the least processing steps, white tea largely retains the nutrients in tea. Since ancient times, people in the country of origin have used white tea to clear away heat and toxic materials, diminish inflammation, sweat, eliminate dampness, relieve summer-heat, treat toothache caused by wind and fire, high fever measles and other miscellaneous diseases.
The role of white tea:
1, can treat diabetes.
Diabetes is the metabolic disorder of sugar, fat and protein caused by insulin deficiency and hyperglycemia. Drinking white tea can cure diabetes, which is a subject that scholars at home and abroad attach importance to and study in recent years. Nana Ogawa Takeichiro, MD, and Minowata Yi, MD, were treating tuberculosis patients with diabetes, and unexpectedly found that white tea had a significant effect on diabetes.
Clinical experiments were carried out on 10 diabetic patients in Imperial University Hospital and Kyoto County Hospital, and it was found that white tea had a significant effect on chronic diabetes. People's Hospital of Quanzhou City, China used "Song Tea" (white tea over 70 years old) to treat diabetes, and the effective rate was 70%. Of course, ordinary tea leaves are also effective, and other drugs can also be added. People in the tea industry in Fuding, the origin of white tea, chose a number of patients with hyperglycemia for experiments. It was found that 765,438+0% of the patients were cured by developing the habit of drinking white tea for half a year.
Therefore, drinking white tea can prevent and treat diabetes, which is scientifically based. Polyphenols and esters in white tea can promote insulin synthesis; Polysaccharides in catechins can remove excessive sugar from the blood. Tea polyphenols can regulate the disorder of glucose metabolism and reduce blood sugar level, thus effectively preventing and treating diabetes.
2. It can prevent cerebrovascular diseases.
Cerebrovascular disease is a common disease, including cerebral embolism, cerebral thrombosis and cerebral hemorrhage, which has a high incidence and seriously affects human health. Its etiology is mainly due to human blood hypercoagulability, red blood cell aggregation and slow blood flow, resulting in thrombosis, or increased fragility of blood vessel wall, which is stimulated by external adverse factors and leads to bleeding.
Why can white tea prevent cerebrovascular diseases? A famous professor of Zhejiang Medical University said: hypercoagulable state is an important condition for thrombosis, and white tea has anticoagulant and fibrinolytic effects, which can change hypercoagulable state without the side effects of general anticoagulants, and has a significant effect on improving health and preventing diseases.
A Chinese medicine research institute has studied white tea and confirmed that tea can reduce blood viscosity. After drinking white tea for 2-3 weeks, the whole blood viscosity decreased from 4.77 to 4.3 1 (P < 0.0 1). The plasma viscosity decreased from 65438 0.66 to 65438 0.58 (P < 0.01). The reduced viscosity of whole blood decreased from 8.58 to 7.97 (P < 0.0 1).
The overall decrease of three blood viscosities shows that white tea has the functions of reducing blood viscosity, lowering blood hypercoagulability, increasing blood fluidity, improving circulation and preventing thrombosis. Because white tea can also prevent the aggregation of red blood cells, which is conducive to reducing blood viscosity and preventing thrombosis.
3, can lower blood pressure
Why can white tea lower blood pressure? This is related to its chemical composition. White tea is rich in tea polyphenols, vitamin C and vitamin P. Tea polyphenols can promote the absorption of vitamin C, and vitamin C can move cholesterol from arterial wall to liver, reduce the concentration of cholesterol in blood, and enhance the elasticity and permeability of blood vessels.
White tea can also indirectly lower blood pressure through diuresis and sodium excretion. Aminophylline contained in tea can dilate blood vessels, make blood flow easily and help lower blood pressure. Up to now, Chinese medicine practitioners in Fujian have used a lot of "Bai Hao Silver Needle" when prescribing, and now Bai Hao Silver Needle is famous overseas for its ability to treat hypertension.
4, anti-virus to improve immunity
The latest research shows that white tea extract may prevent the growth of bacteria causing staphylococcal infection, streptococcal infection, pneumonia and dental caries. Researchers at Pace University in the United States said that previous studies thought that green tea could promote the immune system to resist diseases, but this study showed that white tea extract could indeed destroy the tissues that caused diseases in test tubes, which was proved by repeated studies on white tea extract.
The benefits of drinking white tea
1, cure measles
White tea contains a variety of nutrients and has a variety of functions, some of which are special, such as cancer prevention, heatstroke prevention and detoxification. In particular, white tea stored for a long time can be used as an antipyretic for children with measles, and its antipyretic effect is better than that of antibiotics. In China, North China and Fujian, it is widely regarded as a good medicine to cure measles patients.
Therefore, Zhou Lianggong, a celebrity in Qing Dynasty, wrote in Xiao Min Ji: "The Bai Hao silver needle produced in Hongxue Cave in Taimu Mountain is cold in nature and works as well as the rhinoceros horn. It is a holy medicine for measles.
2. Promote blood sugar balance
The market research of health tea shows that white tea not only contains the inherent nutrients of other tea leaves, but also contains the active enzymes necessary for human body. Medical research at home and abroad has proved that drinking white tea for a long time can significantly improve the activity of lipase in the body, promote lipocatabolism, effectively control insulin secretion, delay intestinal absorption of grape powder, decompose excess sugar in blood and promote blood sugar balance.
White tea is rich in a variety of amino acids, cold and cool, and has the functions of clearing away heat, relieving summer heat and detoxifying. Drinking a cup of Bai Mudan tea in summer in producing areas, few people will get heatstroke. Therefore, Bai Mudan is one of the essential white teas for local tea farmers in summer.
3. Vision
The longer the white tea is stored, the higher its medicinal value will be. Moreover, white tea also contains a lot of provitamin A, which will be quickly converted into vitamin A after being absorbed by the human body. Vitamin A can synthesize rhodopsin, which can make eyes see things more clearly in dark light and prevent night blindness and dry eye.
The Beauty Effect of White Tea
White tea set has high-efficiency antioxidant function, which can enhance skin resistance, prevent discomfort and aging caused by external environment, and keep skin smooth for a long time. Polyphenols in white tea can effectively inhibit free radical activities, improve the detoxification and defense of human body, and have the effect of whitening and detoxifying.
White tea not only contains nutrients inherent in other tea leaves, but also contains active enzymes necessary for human body. Medical research at home and abroad has proved that drinking white tea for a long time can significantly improve lipase activity in human body, promote lipocatabolism, effectively control insulin secretion, delay intestinal absorption of glucose, decompose excess sugar in blood and promote blood sugar balance. White tea is rich in a variety of amino acids, cold in nature, and has the effects of clearing away heat, relieving summer heat and detoxifying.
The function of white tea
Traditional Chinese medicine has proved that white tea is cool to relieve summer heat, and has the effects of clearing away heat and reducing fire, relieving summer heat and detoxifying, and treating diseases. Zhou Liang Gong, a celebrity in Qing Dynasty, wrote in Xiao Min Ji: "Bai Hao Silver Needle, produced in Hongxue Cave in Taimu Mountain, is cold in nature and works as well as rhinoceros horn. It is the holy medicine of measles. "
1, anticancer
In our daily cooking process, sugar, amino acids and other substances are easily converted into heterocyclic amines with carcinogenic effects. Studies have shown that the inhibitory effect of various heterocyclic amine carcinogens in white tea is very significant. The combination of sulindac and white tea will also affect the expression of β -catenin and block the formation of carcinogens, thus playing a role in chemical prevention of cancer. And reduce the toxic and side effects of non-steroidal anticancer drugs (NSAIDs).
2. Lower blood pressure
According to the determination, the content of free amino acids in white tea is obviously higher than that in other teas, especially theanine. Injection of theanine into spontaneously hypertensive rats can significantly reduce blood pressure, and its diastolic blood pressure, systolic blood pressure and average blood pressure all decrease, but the heart rate has no significant change.
3. Reduce blood sugar and blood lipid.
The special processing technology of white tea retains the active enzymes necessary for human body, while the content of other teas is less. Drinking white tea for a long time can significantly improve the activity of human lipoprotein lipase, promote fat catabolism, effectively control insulin secretion, delay glucose absorption, decompose excess sugar in the body and promote blood sugar balance. At the same time, it can promote the secretion of pancreatic juice, reduce the way of blood sugar and increase the way.
4, antipyretic and anti-inflammatory
White tea absorbs less calories during processing, which is the best refreshing drink and has the effect of eliminating dampness and reducing fever. White tea leaves have been circulated among Fuding people for disinfection, anti-inflammation and sterilization. The aged Bai Hao Silver Needle can be used as an antipyretic for children with measles, and its antipyretic effect is better than that of antibiotics. The ancients called it the holy medicine of measles.
5. Antioxidant activity
According to the research results of the Human Nutrition Research Center of the US Department of Agriculture, "a cup of green tea is equal to four cups of orange juice, and a cup of white tea is equal to 12 cups of orange juice".
6. Anti-mutation
Through salmonella experiments, it is found that each group of experiments shows that white tea has better anti-mutation effect than other kinds of tea, which theoretically suggests that white tea has more anti-cancer potential than green tea and black tea.
Note: Salmonella test is used to test whether a chemical has the effect of resisting DNA mutation. The earliest manifestation of healthy cells transforming into cancer cells is DNA mutation.
7. Protect the liver
In vitro experiments show that white tea extract can effectively inhibit the secretion of HBsAg and HBeAg, thus inhibiting the replication and expression of hepatitis B virus.
8. Enhance immunity
White tea is rich in theanine, which is decomposed into ethylamine in human liver, which can mobilize human blood immune cells to respond to external invasion, and then T cells promote the secretion of interferon, forming a "chemical defense line" for human body to resist infection.
9. Lose weight
Obesity is caused by the fact that fat anabolism in adipocytes is greater than catabolism. White tea can obviously inhibit the activity of fat synthase in fat cells, promote the catabolism of body fat, and achieve the effect of losing weight.
