What are the effects, functions and contraindications of Tieguanyin?

Although many people know that Tieguanyin is an oolong tea and that the tea is very good, do they know its specific functions, effects and contraindications? Tieguanyin can resist aging and at the same time, it also has a very obvious effect on the prevention of cancer. Taboos are most easily overlooked by people, so let’s learn about the effects, functions and taboos of Tieguanyin below?

Tieguanyin's efficacy and functions:

1. Detoxification, digestion and greasiness

Inspired by the long history of Anxi Tieguanyin, Zheng Daoxi called Anxi Tieguanyin a "time-honored brand" of the Chinese tea family in his article. The first point he made in discussing the value of this product was that it "can detoxify, help digestion and remove fat." The article says that tea is recognized as the best health drink for mankind. As early as in the Western Han Dynasty's "Shennong Bencao Jing", there was a record that "if you encounter 72 poisons a day, you can get rid of them with tea." In the 20th century, scientists discovered that tea contains a mixture called flavonoids, which has bactericidal and detoxifying effects.

2. Beauty, weight loss and anti-aging

The article said that medical research has shown that the crude catechin combination in Tieguanyin has strong antioxidant activity, which can eliminate reactive oxygen molecules in cells and thus protect the human body from aging diseases. The article mentioned that the content of manganese, iron, fluorine, potassium and sodium in Anxi Tieguanyin is higher than that in other teas. Among them, the fluoride content ranks first among all teas, and it is effective in preventing and treating tooth decay and osteoporosis in the elderly. In 1979 and 1984, Japan experienced two episodes of "oolong tea fever", and Anxi Tieguanyin was even hailed as "beauty tea" and "slimming tea".

Taboos of Tieguanyin:

1. If Tieguanyin is brewed too strong or you drink too much, it will stimulate the increase of stomach acid and gastrointestinal fluid, causing gastrointestinal discomfort. Especially drinking strong Tieguanyin tea on an empty stomach, because of the effect of caffeine, it often causes hyperfunction of the heart and mental excitement. Some people will suffer from insomnia all night until dawn. This is worth noting for patients with heart disease and hypertension.

2. For people with poor gastrointestinal function, there is a greater concern that it may cause gastric ulcers and duodenal ulcers.

3. Drinking strong Tieguanyin tea before meals is harmful to the stomach and intestines. Drinking strong Tieguanyin tea after meals may accelerate the stimulation of the central autonomic nervous system and speed up gastrointestinal digestion. In a short while, we will feel hungry and want to eat again.
