Like most fine Chinese green teas – our Dragon well Green Tea has a high concentration of antioxidant flavonoids and other polyphenols, especially catechins. Because green teas are treated gently and not overly processed, they retain most of their beneficial antioxidants. Catechins are antioxidants that lower cholesterol, blood pressure and so risk of heart attack. It also improves working memory, fight against cancer cells, and may even prevent cell damage. Aside from its rich antioxidant content, dragon well green tea is also rich in Vitamin C, amino acids, caffeine and other healthy substances that make it a good partner in the maintenance of health.
