Acute hepatitis induced by Greater Celandine (Chelidonium majus).

We report on two cases of acute liver injury along with the intake of Greater Celandine (Chelidonium majus), a well-known herbal remedy frequently used for irritable bowel syndrome. All other possible causes of acute liver damage were excluded in both patients. In one patient, cholestatic hepatitis recurred rapidly after involuntary re-exposition. Both patients fully recovered after the withdrawal of Greater Celandine. The two cases add to the existing database about the potential hepatotoxicity of drugs containing Greater Celandine and raise the question whether the approval of this drug should be re-evaluated in the light of lacking evidence for a therapeutic benefit.
