Abstract

Objective: The research was conducted to evaluate the sub-chronic toxicity of Gymnema sylvestre extract through oral administration in experimental animals. The sub-chronic toxicity study was conducted by the recommendation of the WHO in Wistar rats with oral doses of 50 mg/kg/day and 250 mg/kg/day in 12 consecutive weeks. Results: oral administration of Gymnema sylvestre extract at 50 mg/kg/day and 250 mg/kg/day had no effect on general condition, body weight, hematological parameters, hepato-renal functions and histopathological structures of liver and kidney. In conclusion, Gymnema sylvestre extract did not appear to produce sub-chronic toxicity in rats.
