New Hidden Health Properties Found in Green Tea

Ancient Herbal Chinese Green Tea Holds Secret Health Benefits for Skin and Hair in Dermatology Study

green tea.thumbnail New Hidden Health Properties Found in Green TeaIn a study of Experimental Dermatology, scientists divided mice with a genetic predisposition for psoriasis into two groups - one was bathed routinely in warm water and one in a green tea extract mixed with water. The mice bathed in the green tea extract developed skin lesions much later than the mice washed with warm water. Their lesions were also smaller and less inflamed. Scientists concluded that the green tea slowed the production of skin cells by regulating the activity of caspase 14 that is involved in regulating a skin cell’s life cycle.

This research is important because certain treatments for psoriasis and dandruff can have dangerous side effects, Dr. Stephen Hsu, an oral biologist in the MCG School of Dentistry and lead investigator on the study said in a release.

Psoriasis is a disease which affects the skin and joints. It commonly causes red scaly patches to appear on the skin. The scaly patches caused by psoriasis, called psoriatic plaques, are areas of inflammation and excessive skin production. Skin rapidly accumulates at these sites and takes a silvery-white appearance. Plaques frequently occur on the skin of the elbows and knees, but can affect any area including the scalp and genitals. Psoriasis is hypothesized to be immune-mediated and is not contagious.

“The traditional treatment of ultraviolet light and medication, while it can control the lesions and be used long term, may cause squamous cell carcinoma - the second most common form of skin cancer,” he says. “Some of the most effective anti-dandruff shampoos also have carcinogens in them. The bottom line is that we don’t know the long-term effects of using those products continuously.”

Green tea, which is plant-derived, may be an alternative, says Hsu. But scientists must work on developing delivery mechanisms, as the chemicals in green tea are so active that they are oxidized too quickly when mixed with other ingredients. They also dissolve in water, which cannot penetrate the skin’s barrier. Researchers’ goal is to create a balanced formula that can dissolve in fats, which can permeate the skin of humans.
