Our aim of the study is to evaluate the toxicity profile of ACW by acute and sub-acute toxicity studies in rodents. Methods: In acute toxicity studies, mice were orally administered of single doses of 1000 and 2000mg/kg b.w. of methanolic and aqueous extract and sub-acute toxicity studies were performed by administration of 200 and 400mg/kg b.w. orally for 28 days. Results: In acute toxicity studies, administration of methanolic and aqueous extract didn't observe any signs of mortality or toxicity up to 2000mg/kg b.w. No significant change in the physical, biochemical, hematological and histopathology analysis were observed for methanolic and aqueous extracts treated animals in sub-acute toxicity studies. Conclusion: The methanolic and aqueous extract of Amorphophallus commutatus var. wayanadensis is relatively safe for long term oral administration fulfilling the basic priority for its use in traditional medicinal therapies.
