Green Tea

Posted on: April 3rd, 2010 by administrator

In 2735 BC, Chinese Emperor Shen Nung discovered the curative effects of the green tea (Camellia Sinensis) plant. Since that time, the medicinal powers of green tea have been documented to cure a wide variety of aliments. Recently, American research scientists have found that the leaves of the Camellia Sinensis plant contain the polyphenol epigallocatechin gallate (EGCG), the most powerful naturally occurring antioxidant. Unlike other common extracts of the Camellia Sinensis plant (e.g. black tea and oolong tea), green tea is prepared from fresh leaves, thus accounting for the high concentration of active antioxidants. Antioxidants act to counteract the effects of free radicals, deactivating them before they cause harm. Analysis of published studies demonstrates that green tea polyphenols have anti-inflammatory and anticarcinogenic properties. These effects appear to correlate with antioxidant properties of green tea polyphenols. Archives of Dermatology, 2000; 136;989-994

Green tea, specifically the component EGCG, has the ability to block UV-B-induced leukocyte infiltration. Carcinogenesis, 1999; 2117-2124 Induction of skin tumors by UV radiation was significantly reduced by topical, but no oral, administration of purified EGCG through a mechanism distinct from inhibition of photoimmunosupression. Nutrition and Cancer, 1996; 26(3); 325-35

Green tea polyphenols are strong antioxidants, more powerful than vitamin C and vitamin E. When applied directly to the skin, green tea polyphenols reduced UV-induced erythema and sunburn cell formation in human skin. Journal of the American Academy of Dermatology, 2003; 48:1-19

Green tea polyphenols can have an anti-inflammatory and calming effect and have been reported to reduce the appearance of skin redness often associated with rosacea.

Not All Green Tea is the Same - Green tea extracts are popular in many skin care products. However, only purified green tea extracts containing a 90% concentrate of the polyphenol epigallocatechin gallate (EGCG) have been shown to exert berneficial anti-inflammatory and anti-carcinogenic effects. If a product is not labeld as containing 90% polyphenol green tea extract, it most likely is not fully effective. PureRx® products are specially formulated with pure green tea extracts to deliver the beneficial effects of antioxidants directly to the skin. When used as directed, the PureRx® unique five step program is the most effective, easy-to-use system for cleaner, smoother, younger looking skin.
