Anti-diarrheal activity of methanol extract of Litsea polyantha bark in mice

The anti-diarrheal activity of methanol extract of dried bark and aerial parts of Litsea polyantha (MELP) has been evaluated in mice using different models (castor oil-induced diarrhea and propulsive gut motility in mice). MELP (50, 75, 100 mg/kg, p.o.) significantly (P < 0.01) reduced the onset of diarrhea, fecal excretion and also showed a significant (P < 0.001) reduction in gastrointestinal motility on charcoal meal test in mice. The results of the study support the folklore use of the plant for diarrheal remedies.
