Drug-induced, mixed-type hepatitis following ingestion of Cordyceps sinensis.

Metadata-grounded summary

Citation abstract

The use of herbal and dietary supplements is increasing worldwide. Consumers consider it as a natural, and therefore safe and healthy alternative to conventional synthetic drugs and do not expect adverse effects. However, numerous herbal and dietary supplements have been associated with adverse hepatic reactions of variable severity. Recognition of adverse hepatic reactions following the ingestion of herbal and dietary supplements is sometimes difficult since clinical presentation can resemble that of other etiologies unrelated to xenobiotics. Pharmacovigilance is based on spontaneous reporting and, thus, many incidents probably remain unrecorded due to lack of awareness among users and prescribers. The present report describes the first case of cholestatic hepatitis after the intake of an herbal supplement containing Cordyceps sinensis. Causality was considered probable after exclusion of alternative causes, a close temporal relationship, and an immediate dechallenge response with a full remission.
