Brief Introduction

Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, such as red wine, onions, green tea, apples, berries, Ginkgo biloba, St. John’s wort, American elder, and others. Buckwheat tea has a large amount of quercetin. People use quercetin as a medicine.

Quercetin is used for treating conditions of the heart and blood vessels including “hardening of the arteries” (atherosclerosis), high cholesterol, heart disease, and circulation problems. It is also used for diabetes, cataracts, hay fever, peptic ulcer, schizophrenia, inflammation, asthma, gout, viral infections, chronic fatigue syndrome (CFS), preventing cancer, and for treating chronic infections of the prostate. Quercetin is also used to increase endurance and improve athletic performance.

Main Function

1.Quercetin may expel phlegm and arrest coughing, it can also be used as anti-asthmatic.

2. Quercetin has anticancer activity, inhibits PI3-kinase activity and slightly inhibits PIP Kinase activity, reduces cancer cell growth via type II estrogen receptors.

3.Quercetin may inhibit histamine release from basophils and mast cells.

4. Quercetin may control the spread of certain viruses within the body.

5, Quercetin may help reduce tissue destruction.

6.Quercetin may also be beneficial in the treatment of dysentery, gout, and psoriasis

Green Tea: the Marvelous Drink

1Longevity
Green tea may protect against death from all causes, especially cardiovascular disease. Japanese scientists[1] analyzed data from a National Cohort Study that began in 1994 and had over 40,000 participants, age 40 to 79, who initially were free of stroke, heart disease and cancer. People were followed for up to 11 years.
Compared with participants who consumed less than 1 cup of green tea per day, those drinking 5 or more cups a day had a significantly lower risk of death from all causes, especially lower risk of dying from cardiovascular disease and stroke. The findings might explain in part the reason why the Japanese live longer than people in any other country. However, there was no cancer prevention benefit of green tea.
2Memory and learning
One of the important health benefits of regular green tea drinking is improved memory and learning ability. In Japan there was revealed[2] that high green tea drinking maintains cognitive function. Also, green tea consumption may enhance learning and memory ability[3].
The main components of green tea that are thought to work on improving brain function are polyphenols, epigalochatechin-3-gallate (EGCG), a very strong antioxidant. The high use of oxygen during the metabolic processes leads to the generation of a large number of free radicals (highly reactive molecules). EGCG can penetrate the brain’s blood barrier and is able to enact its antioxidative affects on the free radicals that cause damage in the brain.
3Weight control
There is strong evidence that green tea has fat-burning properties and promotes weight loss, especially when combined with increased physical activity and a healthy diet. Green tea polyphenols are known to increase the metabolism of fats by the liver (thermogenic effect), inhibit lipase (fat absorption enzyme) in the digestive tract, and provide a feeling of satiety and fullness[4]. Green tea can reduce body weight in obese persons by increasing energy expenditure and fat oxidation[5].
Continuous ingestion of a green tea extract high in catechins promotes reduction in body fat, systolic blood pressure, and LDL cholesterol, that in its turn contributes to a decrease in obesity and cardiovascular disease risks.
4Skin protection from Ultraviolet
Green tea polyphenols protect the skin from the damage caused by ultraviolet radiation such as UV-induced sunburn, UV-induced immunosuppression and photoaging of the skin. They exert photoprotection by various cellular, molecular and biochemical mechanisms[6]. Also, green tea polyphenols protect the skin by improving the elastic tissues
