The history of tea dates back to ancient China, almost 5,000 years ago. According to legend, in 2732 B.C. Emperor Shen Nung discovered tea when leaves from a wild tree blew into his pot of boiling water. He was immediately interested in the pleasant scent of the resulting brew, and drank some. Legend says the Emperor described a warm feeling as he drank the intriguing brew, as if the liquid was investigating every part of his body.
Natural substances, called polyphenols, are found in both caffeinated and herbal teas. These substances are antioxidants, compounds that may help reduce the risk of certain chronic diseases. During processing, some of the polyphenols in tea are destroyed. Thus, tea powders, decaffeinated teas and bottled tea drinks may not offer the same health benefits. Additionally, research suggests that green teas offer a greater antioxidant punch compared to most other varieties.
