Evaluation of adaptogenic activity profile of herbal preparation.

The herbal formulation, AVM is a proprietary formula that consists of extracts of herbs that have been used in Indian traditional medicine to promote physical and mental health, improve defense mechanisms of the body and enhance longevity. AVM (500 and 1000 mg/kg) was tested for its adaptogenic activity by determining antistress, anabolic and immunomodulatory effects. In antistress activity, pretreatment with AVM significantly attenuated the changes in ascorbic acid (from blood and adrenal), cortisol (from plasma and adrenal) and adrenal gland weights induced due to restrain stress (physical immobilization). Its antistress effect at 1000 mg/kg was comparable to that of diazepam (5 mg/kg) treated group. Leucopenia, and anemia induced by cyclophosphamide (CYP) was shown to reduce significantly by AVM. Treatment of AVM + CYP had increased spleen and thymus weights significantly as compared to CYP alone treated group. The anabolic activity was evaluated by weight gain of the levator ani muscle, ventral prostrate gland and seminal vesicles in rats as compared to untreated control.
