ABSTRACT
It is known that silibinin has antioxidant, anti-tumor, anti-inflammatory and immunomodulatory effects, and which is widely used for liver damage caused by a variety of reasons. In recent years, it is found that silibinin has potential anti-allergic reactions. However, even larger doses of silibinin still show no significant side effects . The rare literature reports that silibinin can cause allergic reactions. The paper reports a middle-aged patient who orally took silibinin for the prevention of tuberculosis chemotherapy-induced liver damage, and he occurred symptoms of lip pain and anabrosis, foreign body sensation, and difficulty eating one day after treatment. The patient was misdiagnosed as"vesicular stomatitis"and was treated by anti-viral therapy. The patient was discharged from the hospital after treating allergic reactions. As a safe and effective drug for prevention of liver damages in clinic, silibinin should be alert to induce possible allergies when there are local skin manifestations such as lip pain and anabrosis.
