Bacopa monniera Wettst. (BM, syn. Herpestis monniera L; Scrophulariaceae), is an
Ayurvedic drug used as a rasayana. Its fresh juice was earlier reported to have
significant antiulcerogenic activity. In continuation, methanolic extract of BM
(BME) standardized to bacoside-A content (percentage-38.0 +/- 0.9), when given
in the dose of 10-50 mg/kg, twice daily for 5 days, showed dose-dependent anti-ulcerogenic
on various gastric ulcer models induced by ethanol, aspirin, 2 h cold restraint
stress and 4 h pylorus ligation. BME in the dose of 20 mg/kg, given for 10 days,
twice daily showed healing effects against 50% acetic acid-induced gastric
ulcers. Further work was done to investigate the possible mechanisms of its
action by studying its effect on various mucosal offensive acid-pepsin secretion
and defensive factors like mucin secretion, mucosal cell shedding, cell
proliferation and antioxidant activity in rats. BME 20 mg/kg showed no effect on
acid-pepsin secretion, increased mucin secretion, while it decreased cell
shedding with no effect on cell proliferation. BME showed significant
antioxidant effect per se and in stressed animals. Thus, the gastric
prophylactic and curative effects of BME may be due to its predominant effect on
mucosal defensive factors.
