Chinese teas offer many health benefits due to their antioxidants and essential nutrients. Some of the reported benefits include boosting metabolism, aiding digestion, improving mental focus, and promoting relaxation. (But not if you drink it too late at night, as the caffeine can lead to insomnia.) However, it is important to note that these benefits can vary based on the specific tea type and brewing methods used. It will also vary from person to person. Some people have gastrointestinal issues from drinking tea.
