Liver injury induced by a Japanese herbal medicine, sairei-to (TJ-114, Bupleurum and Hoelen Combination, Chai-Ling-Tang) R1.

The case is reported of a man who showed acute hepatitis with jaundice after he was given a Japanese herbal medicine, sairei-to (TJ-114, Bupleurum and Hoelen Combination, Chai-Ling-Tang). Unusually, the component thought to be responsible for the observed drug-induced liver injury was able to be identified. Lymphocyte migration inhibition testing indicated that the tuber of the perennial herbage Pinellia ternate was the causative agent.
