A 67-year-old man visited our hospital with anorexia and abdominal discomfort after taking herb for 3 months. Abdominal computed tomograpy showed splenomegaly. Blood test showed elevation of serum alanine aminotransferase level, thrombocytopenia, and there was no viral or autoimmune hepatitis. Liver biopsy showed comprehensive fibrotic changes and necrosis on iver parenchyma. He recovered within 1 week after stopping the herb. There was no disease recurrence for 1 year. No case of toxic hepatitis by taking Fritillaria thunbergii Miquel has been reported. Thus, this case proved for the first time that Fritillaria thunbergii Miquel could cause drug induced liver injury.
