Practice has proved that each herbal tea has different properties, different brewing, different water temperature requirements and different health care effects. So I suggest you: if you don't know these problems before, or professionals don't know them, you'd better not mix them at will to avoid side effects, which will not only fail to play a health care role, but also may cause some allergic symptoms.

Originally, drinking herbal tea was for health care, but don't try health and life!
