Damage to the liver from Xia Ku Cao is not known. Xia Ku Cao is pungent, bitter and cold in nature. It belongs to liver and gallbladder meridians. It has the effects of clearing liver and fire, brightening eyes, dispersing knots and eliminating swelling. It is used in the treatment of red, swollen and painful eyes, headache and dizziness, nocturnal pain in the eyes, scrofula (mainly refers to tuberculosis of the lymph nodes in the neck), gall tumors (equivalent to thyroid tumors), carbuncle (red, swollen and painful breasts with poor discharge of milk, eventually forming a suppurative disease), and breast swelling and pain. The adverse reactions and contraindications of Xia Gu Cao are not clear. However, the drug is bitter and cold and should be used with caution by those with weak spleen and stomach. There is no clear basis for suggesting that Xia Ku Cao is damaging to the liver. In general, as long as it is used according to the specific conditions of the patient and standardized under the guidance of a professional doctor, it will not cause damage to human health. Chinese medicines should be used after identification by a professional Chinese medicine practitioner, and should not be used blindly on their own to avoid adverse consequences.
