Acute liver injury following turmeric use

Curcumin supplements have shown some evidence of benefit in the treatment of osteoarthritis (1).

Curcumin is extracted from the plant turmeric (Curcuma longa)

• content of curcuminoids in turmeric powder is 3.14%, which is used as a spice in cuisines of the Middle East and Indian subcontinent (2) - much higher amounts of curcumin are present in over the counter supplements than is found in turmeric powder (3)

A case report describes a curcumin-induced hepatocellular DILI (drug-induced liver injury) in a 78-year old female admitted with jaundice, with a one-month latency (3)

A systematic review of case reports in Tuscany concluded that "evaluation of Italian cases of Curcuma longa-induced acute hepatitis and the systematic review of literature confirmed the association between Curcuma longa and liver injury.." (4)
