Ever since its discovery in China, tea has been appreciated for its medicinal qualities. In more recent times research has focused upon the abundant polyphenols that are found in tea - particularly in green and white tea and their antioxidant effects. Polyphenols are said to neutralise free radicals which may help to halt or slow down the onset of illnesses such as cancer and cardiovascular disease. Jasmine is said to have calming properties so helps alleviate stress and a cluttered mind.
