Chinese Tea for Diabetes

Chinese tea has the effect of lowering blood sugar, blood lipids, and cholesterol, and treating hypertension, thereby achieving the effect of controlling diabetes.

Diabetes is a group of metabolic diseases characterized by high blood sugar (hyperglycemia). Hyperglycemia is caused by the deficiency of insulin secretion or the damage of its biological function.

The main causes of diabetes are genetic factors and environmental factors. Diabetes or long-term high blood sugar can cause chronic damage and dysfunction in various organs and tissues, especially the eyes, kidneys, heart, blood vessels, and nerves.

At present, there is no cure for diabetes, but diabetes can be controlled by a variety of treatments. It mainly includes five aspects: education for diabetic patients, self-monitoring blood sugar, diet therapy, exercise therapy, and drug therapy.

Diet therapy is the basis of diabetes treatment, and some patients with mild diabetes can control their condition with diet therapy.

Drinking tea is a good choice for diet therapy. Regularly drinking tea not only has a health-preserving effect but also can control diabetes.

Green Tea

Green tea is a kind of unfermented tea that retains the natural nutrients of the fresh leaves, especially the content of tea polyphenols which is more than 85%. Tea polyphenols have the effect of lowering blood sugar and improving liver and kidney function.

Diabetic patients are susceptible to atherosclerosis. Tea polyphenols can effectively inhibit atherosclerosis.

Scientific research shows that EGCG (Epigallocatechin gallate) in green tea can play a part in the role of insulin. EGCG can significantly lower blood sugar.

In 2019, a research paper was published in Science Translational Medicine. The paper shows a new function of green tea in the treatment of diabetes. When the human body needs to implant some kind of customized cells, people only need to drink special green tea.

After green tea enters the human body, tea catechins and phenolic acids are rapidly metabolized into the antioxidant protocatechuic acid (PCA), which can control the secretion of insulin so as to replace the diabetes treatment method of insulin injection.

Black Tea

Black tea is a kind of fermented tea that generates theaflavins and thearubigins during the fermentation process.

Theaflavins, known as “soft gold” in tea, have a good function of lowering blood lipids and have no toxic side effects. This study was published in JAMA, an international authoritative medical journal.

A common symptom of diabetic patients is abnormal cholesterol. Theaflavins can not only combine with cholesterol in the intestine to reduce the absorption of cholesterol but also inhibit cholesterol synthesis in the human body.

Theophylline is abundant in black tea, and it is an important component of the red color of black tea. Theophylline is a powerful antioxidant that helps aging organisms resist biological oxidation.

White Tea

White tea is a slightly fermented tea. Long-term drinking white tea can effectively control insulin secretion, promote fat catabolism, and decompose excess sugar in the blood.

The tea polysaccharide contained in white tea is a kind of acid glycoprotein, which combines with a large number of trace elements. Modern medical research shows that tea polysaccharide is the main pharmacological component of tea in the treatment of diabetes.

As early as 2009, the Fuding Municipal Government commissioned the Institute of Nutrition and Food Safety of China to do the blood sugar reduction experiments of white tea. Fuding is a county of Fujian Province and it is the hometown of white tea.

The experiments had shown that the appropriate high dose of Bai Hao Yin Zhen can effectively lower blood sugar and improve the symptoms of diabetes.

Burdock Tea

Burdock also called Niu Bang is traditional Chinese medicine. The medicinal part is the roots of burdock.

Burdock tea is a pure natural tea made from burdock roots. Burdock has the effects of treating diabetes, hypertension, and hyperlipidemia, anti-cancer, detoxification, and so on. Scientific experiments show that the water extract of burdock can significantly reduce blood sugar.

Burdock tea is also rich in water-soluble cellulose, which can help to interrupt the cycle of cholesterol and promote the elimination of cholesterol. It is very suitable for diabetics to drink.

Kuding Tea

Kuding is a kind of traditional Chinese medicine. Kuding tea literally called Bitter Nail tea is also a natural tea. It was regarded as a tribute tea in the Song Dynasty (960-1279).

Kuding tea has a good curative effect on diabetes, hypertension, hyperlipidemia, and cardiovascular diseases, so it is favored by middle-aged and elderly people.

For patients with hypertension, hyperlipidemia, and hyperglycemia, drinking Kuding tea can lower blood pressure, blood lipids, and blood sugar within 20 to 30 days.

Besides, Kuding tea can boost the immune system and has a certain effect on the treatment of cardiovascular and cerebrovascular diseases.

Corn Silk Tea

Corn silk tea is made from the stigma of Zea mays L. Corn silk is used as a traditional Chinese medicine in China. In traditional Chinese medicine, corn silk is also called “dragon beard” due to its healthcare function.

Corn silk tea not only has the effect of clearing heat and detoxifying, but has a significant effect on lowering blood lipids, blood pressure, and blood sugar. Corn silk porridge is commonly used to treat diabetes in southern China.


These kinds of tea are very popular for diabetic patients. In addition to dietary therapy, diabetic patients should cooperate with exercise therapy to control diabetes.

Proper exercise can improve the body’s sensitivity to insulin, reduce body weight and body fat, enhance physical strength, and improve workability and quality of life.
