Green tea, a minimally oxidized version of tea made of Camellia sinensis. It originates in the country of China but largely associated with many other cultures in Asia and the Middle East. Extracts have been gaining popularity as key ingredients in skin care preparations designed to treat skin as an anti-aging compound. Green tea polyphenolic compounds have significant antioxidant and anti-inflammatory activities, and recent studies suggest that these extracts help mediate ultraviolet radiation damage.
One of the more notable studies was published in the Journal of American Medical Association in September 2006 and detailed a study in Japan that followed several thousand regular green tea drinkers over eleven years. This study indicated that those who drank more of the beverage during this time had fewer cases of heart disease, especially women.
This wonder brew is full of antioxidants, in fact it is considered to be one of the best sources of antioxidants available. This is due to the fact that green tea contains an amazing amount of polyphenols named EGCG (which is actually a flavonol). This healthy drink contains up to 10 times the amount of the polyphenols over black tea, and its all because of the way green tea is made – by steaming fresh tea leaves. Modern medical research has linked a diet high in EGCG to fighting off cancer and regulating blood pressure levels.
At the end of the study when the results were reviewed, no significant differences in clinical grading were found between the treated and placebo groups, other than higher subjective scores of irritation in the treated group.
Histologic grading of skin biopsies did show significant improvement in the elastic tissue content of treated specimens. Participants treated with a combination regimen of topical and oral green tea showed histologic improvement in elastic tissue content. Green tea polyphenols have been postulated to protect human skin from the cutaneous signs of photoaging, but clinically significant changes could not be detected. All results from all testing have proven one thing, over and over again, and that is that Green Tea is one of three natural weight loss secrets that actually works.
