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]
