Research to now has not been able to explain how this works.
It is used for the treatment of genital warts too. The tea’s cafeine enhances thinking and alertness, increases urine production, and may improve the function of brain messengers critical in Parkinson’s disease.

Preparation of Green Tea
Depending on the type and variety of green tea you wish to brew, the brewing temperature and steeping time guidelines may differ. If the tea packaging does not include brewing instructions, ask your tea dealer for advice.
Here are some general tea-making guidelines to remember while making it. Use filtered water that is fresh, pure, and cool. These teas are usually made in short infusions at 160 to 180 degrees. Don’t let your tea become too hot! If the water is overly hot, especially for this tea, the bitterness and astringency of the tea will be released more quickly. If you don’t have an electric kettle with temperature control, let the water cool before pouring it over the leaves. It depends on the tea, but a good bet is to use roughly 2 grams of loose leaf tea per 8 oz. cup of water. Use the steeping instructions on your tea package if it has them. To maintain all of the heat in the steeping vessel, cover the steeping tea.
Note: For an early harvest, more delicate teas, steep for 30 to 60 seconds; for regular harvest, more powerful teas, steep for 2 to 3 minutes. The majority of high-quality loose leaf teas can be steeped more than once.
Dosages of Green Tea

Every day, different amounts of this nutrinious tea will help you in different ways.

It’s excellent to have green tea in your diet, but as long as you drink a cup or more every day, that’s fine!
