Pre-clinical toxicity evaluation of leaf-stalk extractive of Piper betle Linn. in rodents.

Studies on pre-clinical toxicity were undertaken to determine the haematological and biochemical changes after administration of alcoholic extract of leaf-stalk of P. betle in rats and mice. Acute and chronic toxicity experiments were performed on mice and rats according to WHO protocol. Different doses of plant extractive were administered for toxicity studies on short and long term basis. Haematological, biochemical profiles and enzymatic studies (transaminases and phosphatases) indicated that the drug (plant extractive) was devoid of toxicity.

Effect of Piper longum Linn, Zingiber officianalis Linn and Ferula species on gastric ulceration and secretion in rats.

Use of Dipaniya Mahakasaya, a group consisting of 10 herbal drugs, has been suggested in Charaka Samhita to improve digestion. Out of these 10 plants, three, viz. P. longum (water decoction), Z. officianalis (water decoction) and Ferula species (colloidal solution) were studied for their antiulcer and mechanism of antiulcer effects in rats. All the drugs in the dose of 50 mg/kg, p.o., 60 min prior to experiment, showed significant protection against gastric ulcers induced by 2 hr cold restraint stress, aspirin (200 mg/kg, 4 hr) and 4 hr pylorus ligation. The antiulcerogenic effect seemed to be due to the augmentation of mucin secretion and decreased cell shedding rather than offensive acid and pepsin secretion which however, were found to be increased by them.
