Chebulagic acid is a benzopyran tannin and an antioxidant that has many potential uses in medicine.

It has been found to be immunosuppressive,[1] hepatoprotective,[2] and a potent alpha-glucosidase inhibitor,[3][4] a human gut enzyme useful in diabetic studies.

It has been shown to be active against Staphylococcus aureus and Candida albicans.[5]

It is found in the plants Terminalia chebula, T. citrina and T. catappa.[6]

It is formed from geraniin through a glutathione-mediated conversion.[7]
