Green tea is non-fermented tea, because of its characteristics, it retains more of the natural substances in the fresh leaves. Among them, tea polyphenols and caffeine retain more than 85% of fresh leaves, and chlorophyll retains about 50%, and the loss of vitamins is also less, thus forming the characteristics of green tea "clear soup with green leaves, strong astringency in taste". It has special effects on anti-aging, anti-cancer, anti-cancer, sterilization, and anti-inflammatory, which is beyond the reach of fermented tea.
