Safety Profile of a Polyherbal Formulation () in Female Rats by Subchronic Oral Toxicity Study

Abstract

Gynocare capsules, is a polyherbal formulation, are used as uterine tonic and for treating gynaecological ailments like infertility, leucorrhea, and menstrual disorders. The formulation contains ingredients of herbal origin, such as, extracts of Ashoka, Vasaka, Durva, Chandan, Musk, and so on. It was evaluated for its safety at the therapeutic dose level by a repeated dose oral toxicity study in albino Wistar rats. The herbal formulation was administered orally at a therapeutic dose of 100 mg/kg/day, for 90 days. All animals were monitored daily for their health status and signs of abnormalities. The body weight, water consumption, and food intake were measured once weekly. At the end of the experimental period, various hematological and biochemical parameters were estimated and histopathologies of selected organs were conducted. The study resulted from the long-term oral administration of Gynocare capsules (100 mg/kg), did not cause any relevant signs of toxicity nor significant changes in the physical, hematological and biochemical parameters. However, statistically significant differences were seen in the relative organ weights of adrenal gland, ovary, and serum creatinine levels. The reduction in ovary weight revealed the possibility of the drug targeting the ovary. Moreover, no pathological features were identified in the treated group as monitored by the histopathological analysis of the internal organs. The study established that Gynocare capsules at the dose given (100 mg/kg) did not induce any remarkable or significant toxic effects, indicating that it was safe in rats following oral administration for 90 consecutive days.
