There is no evidence that Epimedium is harmful to the liver. Epimedium is warm in nature, sweet and pungent in flavor, and belongs to the kidney meridian as well as the liver meridian. It is the stem and leaves of Epimedium, a plant of the genus Epimedium in the family Berberidaceae, which has the effects of tonifying the kidney and strengthening the yang (tonifying the kidney yang), reinforcing the tendons and bones, and dispelling wind and removing dampness (dispelling wind and dampness from the body). In clinical practice, it can be paired with drugs such as Ba Ji Tian and Wei Ling Xian for the treatment of impotence, spermatorrhea, lumbar and knee soreness and coldness, fatigue, frequent urination, and rheumatic paralysis and pain. Adverse reactions such as nausea, vomiting and abdominal distension may occur after the use of this drug, but the above reactions can usually disappear on their own. At present, there is no clear clinical evidence that can indicate that Epimedium will produce bad effects on the liver. Patients with external fever, solid internal heat, and yin deficiency and fire (deficiency of yin and essence in the body, resulting in hyperactive deficiency and fire) should not use a single medicine for a long period of time. Patients with chickenpox should not use this medicine. If patients need to use the medicine, they should be under the guidance of a doctor and should not use the medicine without authorization.
