The main difference between buckwheat tea and tartary buckwheat tea is the different raw materials and the different treatment directions. Specifically, buckwheat tea is mild in nature and can nourish the stomach and strengthen the spleen. But bitter buckwheat tea is mostly cold. In the application process, drinking buckwheat tea is not as effective as drinking tartary buckwheat tea for getting angry, upset, constipation and acne on the face. Because tartary buckwheat tea has obvious fire-dispelling symptoms, it is the most ideal to treat the symptoms of excessive internal heat according to its cold characteristics.
