I can't say that there are no side effects.
Since Chinese herbal medicine is also a "meds", the side effects are not zero at all.
Because Chinese herbal medicine is a natural crude drug, there are few side effects if you take medicine that suits your constitution, and it is very good, but if you use a medicine that does not fit your type, you may cause unpleasant symptoms. I have. It is important to have a specialized pharmacist mix.
If the side effects are suspected, stop taking immediately and consult a pharmacist. Unlike side effects, unpleasant symptoms such as diarrhea, nausea, dizziness, headache, and rash may appear when you start taking Chinese medicine. This is a phenomenon called "meditation".
Med meditation occurs when the body is starting to heal for chronic symptoms. In fact, it temporarily worsens, despite the fact that the prescription is right.
It is difficult to judge the difference between side effects and meditation, so if you have a different symptom, be sure to consult a specialized pharmacist without yourself.
