Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Phytoalexins are chemical substances produced by plants as a defense against infection by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.
Polyphenols (Tea Polyphenols) is tea polyphenols in general, including flavanols, anthocyanins, flavonoids, flavonols and phenolic acids and the like. Mainly flavanol (catechin) type, accounts for 60 to 80% catechin. Substances known as polyphenols or tannin tea tea tannin, is one of the main ingredients of tea color, flavor formation, but also one of the main ingredients in tea health functions. Studies have shown that polyphenols and other active substances with detoxification and anti-radiation effect, can effectively prevent radioactive substances invade the bone marrow, and strontium 90 and cobalt-60 can rapidly excreted, the health and medical profession as "radiation nemesis."
The genus of Scutellaria includes approximately 300 species. Scutellaria baicalensis georgi from the Lamiaceae family is said to be one of the potent medicinal herbs and is thus used to treat a number of health disorders for over two thousand years. It is a perennial herb, which grows to a height of 1-4 feet. It has four-angled stems with multiple opposite leaves. Its blue to purple flowers are characterised by the specific shape, which resembles the scull. Two petals of the flower are often called lips. The flowers, blooming in July, are situated on one side of the stem. The root of the herb is thick and branchy. It is almost skinless.
Chinese scullcap (Scutellaria baicalensis) is different from a related plant called American scullcap (Scutellaria laterifolia). Used more extensively in Asia than in the Americas or Europe, scullcap contains active flavonoids, chemicals that have a wide range of effects in the body. Two of its flavonoids, baicalin and wogonin, are known to be anti-inflammatory. Inflammation is the body response to irritation, injury, or infection. It usually includes pain, redness, and swelling in the area of the damage and it can occur within body tissues as well as on the surface of the skin. Both oral and topical forms of scullcap are being tested to treat inflammatory conditions that range from dermatitis to inflammatory bowel disease.
