Many traditional Chinese medicines are toxic, but the toxicity is relatively small. These traditional Chinese medicines can be used to treat diseases without any toxic reaction to patients. For example, Ligustrazine, Aconitine, Caocao, Pinellia ternata, etc., if taking too much Aconitine will increase the heart rate and lead to heart failure. Pinellia ternata is very toxic. If eaten directly, it will be poisoned, and in severe cases, it will be life-threatening.
