Green tea is a type of tea that is made from Camellia sinensis leaves and buds that have not undergone the same withering and oxidation process used to make oolong teas and black teas. Green tea originated in China, but its production and manufacture has spread to other countries in East Asia. Several varieties of green tea exist, which differ substantially based on the variety of C. sinensis used, growing conditions, horticultural methods, production processing, and time of harvest. Regularly drinking green tea can help you lose weight and reduce your risk of several diseases, including diabetes, heart disease and cancer. Drinking three to five cups of green tea per day seems to be optimal to reap the most health benefits. Green tea’s anti-inflammatory properties can help reduce skin irritation, skin redness, and swelling. Applying green tea to your skin can soothe minor cuts and sunburn, too. Due to its anti-inflammatory properties, studies have also found topical green tea to be an effective remedy for many dermatological conditions.
