Since green tea has not been fermented, the most original substances in the fresh leaves of the tea tree are preserved to the greatest extent. Among them, many nutrients such as tea polyphenols, amino acids, and vitamins have been retained in a large amount, which provides the basis for the health benefits of green tea.
