Tinospora cordifolia (Guduchi/Giloy)-Induced Liver Injury: A Case Review

Tinospora cordifolia (Guduchi/Giloy) is a relatively common herbal supplement whose use has recently become prominent in Southeast Asia. It was promoted to the public in India as an immunity booster, especially against the novel COVID-19. There have been reports, mostly from India, of an association between Guduchi/Giloy and liver injury. We present a 50-year-old female with a history of Hashimoto thyroiditis, who presented with abdominal discomfort and nausea of two weeks duration, which coincided with starting HistaEzeTM supplement containing Tinospora cordifolia. The vital signs upon presentation showed no significant abnormalities. Labs were significant for severely elevated transaminases; however, viral panels, autoimmune serologies, and imaging studies were unremarkable. Roussel Uclaf causality assessment method (RUCAM) score was at 6, which was indicative of probable drug/herb-induced liver injury. HistaEzeTM was discontinued, and the patient took a three-day course of oral steroids with significant interval improvement in clinical status, as evidenced by progressive normalization of the transaminases level. The transaminases decreased by greater than 50% within two weeks of discontinuation and trended back to baseline within three months. This case highlights the worldwide availability and use of Tinospora cordifolia, which can cause liver injury that appears to be idiosyncratic and possibly immune -mediated. Further research on the precise mechanism of its hepatotoxicity is warranted.
