[Drug-induced liver injury caused by a dietary supplement (Kin-toki Shoga(®)) made from ginger].

A 70-year-old woman who took a dietary supplement, Kin-toki Shoga(®) made from ginger for peripheral psychroesthesia and numbness, experienced an epigastric sense of incongruity and appetite loss and passed brown urine for 2 months. Although she had stopped taking the supplement, her symptoms had not improved. She was admitted to our hospital because of jaundice and liver dysfunction. After an investigation of causes, she was diagnosed with drug-induced liver injury caused by Kin-toki Shoga(®). Liver dysfunction gradually improved with conservative treatment. She was discharged on the 25th day of illness. Liver biopsy findings were compatible with drug-induced liver injury.
