The plant Indigofera aspalathoides is used by a large number of tribes in India for the treatment of various hepatic disorders and abscesses. The methanol extract of Indigofera aspalathoides (MEIA) was evaluated for its protective effects on gastric mucosal lesion in Wister albino rats against indomethacin, histamine and ethanol induced gastric mucosal damage. The response to MEIA was assessed using the ulcer index, thiobarbituric acid reactive substance (TBARS), and glutahione level. MEIA pretreatment showed protection against chemical induced gastric mucosal damage, a significant reduction in the ulcer index and TBARS activity and increase glutathione level as compared with that of standard drugs.
