Green tea retains more of the natural substances in the fresh leaves. More than 85% of the tea polyphenols and caffeine in the fresh leaves are retained, and about 50% of the chlorophyll is retained, with less vitamin loss, thus forming the characteristics of green tea with clear soup, green leaves, fresh taste, and strong astringency. Scientific research results show that the natural ingredients retained in green tea have anti-aging, anti-cancer, sterilization, anti-inflammatory and other effects that are unmatched by other teas. It is suitable for young people, computer workers, and people who smoke and drink.
