Abstract

Context: Amorphophallus paeoniifolius tuber is an important constituent of Ayurvedic system of medicine. The tuber of this plant has high medicinal value and is consumed as a food. It is associated with acridity (itchy sensation in mouth and throat) upon oral consumption and presence of high oxalates raphides. Aims: To evaluate the acute and subacute oral toxicity studies of methanolic (APME) and aqueous (APAE) extracts of Amorphophallus paeoniifolius tuber in Swiss albino mice according to OECD guidelines. Methods: In acute oral toxicity study, the mice were orally administered a single dose of APME or APAE (2000 mg/kg) and clinical signs and mortality were observed for 14 days. In subacute (repeated dose) oral toxicity study, the mice were administered once daily, orally with APME or APAE (1000 mg/kg) up to 28 days. The parameters assessed were behavior, clinical signs, body weight, feed and water consumption, urinary, biochemical, hematological and major organ weights and histology. Results: In acute toxicity study, there was no treatment related mortality and morbidity in any of the group. In subacute toxicity study, there were no significant changes in behavior, body weight, feed and water consumption, urinary, biochemical, hematological and organ weight and histological parameters compared to vehicle treated group. There was no treatment related mortality or morbidity. Conclusions: Administration of methanolic and aqueous extracts of Amorphophallus paeoniifolius tuber, individually in acute and 28 days repeated dose in mice, did not exhibit any toxicity or adverse effect at the doses used.
