Immunomodulatory effect was assessed in carbon clearance test, delayed type of hypersensitivity (DTH), T- cell population test, and sheep erythrocyte agglutination test (SEAT) in animal treated with methi at doses of 200 and 400 mg/kg body weight. In carbon clearance test, Fenugreek exhibited significantly high phagocytic index against control group, indicating stimulation of the reticulo-endothelial system. Significant decrease in mean difference, in the foot paw thickness in DTH indicates its anti-inflammatory activity. In Fenugreek treated groups at 200 and 400 mg/kg doses showed significant increase in antibody titer against control in normal immune status animals while in T-cell population test, showed significant increase in T-cell rosette formation against control. These results confirm the immunomodulatory activity of Fenugreek extract, which is a known immunomodulator in indigenous medicine. Keywords: Immunomodulators, Trigonella foenum-graeceum, Dlayed type hypersensitivity. ______________________________________________________________________________ INTRODUCTION Herbal drugs are known to possess immunomodulatory properties and generally act by stimulating both specific and nonspecific immunity. Many plants used in traditional medicine have immunomodulating activities [1]. Natural adjuvants, synthetic agents, antibody reagents are used as immunosuppressive and immunostimulative agents. But there are major limitation to the general use of these agents such as increased risk of infection and generalized effect throughout the immune system. Immunosuppression is a major drawback in conventional therapy of cancer such as radiation and chemotherapy. Both these method have sever side effect such as nausea, vomiting, alopecia, mucosal ulceration etc. Modulation of immune responses to alleviate the diseases has been of interest for many years and the concept of ‘Rasayana’ in Ayurveda is based on related principles. Immunostimulation in a drug-induced immuno- suppression model and immunosuppression in an experimental hyperreactivity model by the same preparation can be said to be true immunomodulation [2-4]. Apart from being specifically stimulatory or suppressive, certain agents have been shown to possess activity to normalize or modulate pathophysiological processes and are hence called
