The possible side effects of the drug after the use of calamus are still unclear, and there is no literature to prove the toxicity of the drug. However, due to the warm nature of the drug, more than one dose for a longer period of time or the wrong medicine may cause mouth and tongue sores, sore throat, constipation and other discomforts. It is recommended to have a professional doctor to formulate a prescription after diagnosis, and reasonably combine with other medicines to improve the therapeutic effect.

The adverse reactions and contraindications of this product are not clear.
