This document discusses the chemistry and health applications of green tea. It begins by introducing green tea as a type of tea made from Camellia sinensis leaves that is not oxidized. It then describes the manufacturing process and lists the main chemical components of green tea, including catechins, vitamins, minerals, carbohydrates, and caffeine. The document explains that catechins are powerful antioxidants in green tea and discusses their role in free radical scavenging. Finally, it reviews research on the health benefits of green tea for conditions like cancer, Alzheimer's, diabetes, and obesity, but also notes that excess consumption can cause side effects like caffeine sensitivity, interactions with blood thinners, and dehydration.
