Buckwheat tea has many functions, such as clearing away heat, preventing cancer and diminishing inflammation. However, from the information of our long-term sales feedback, the above three effects are the most obvious, so our publicity focuses on these three points, but at the same time, we should also know why tartary buckwheat tea has this effect: First, the three highs are reduced, because tartary buckwheat contains rutin (vitamin P) which is not contained in other food crops, and rutin has the functions of softening blood vessels, enhancing blood vessel permeability and strengthening insulin periphery. Second, regulating the stomach is because tartary buckwheat contains amylopectin and dietary fiber that protects the gastrointestinal membrane. Third, beauty is because tartary buckwheat contains dihydro-cis-cinnamic acid beauty ingredients, which have spots and whitening effects.
