The present study was intended to prepare herbal formulation, PMM3 using purified and modified parts of five common Indian herbs like, Trigonella foenum-graccum, Tinospora cordifolia, Scoparia dulcis, Adhatoda vasica and Cassia occidental. PMM3 was standardized using physico-chemical, phytochemical, UV-VIS spectral, HPTLC, AAS and GC methods. The phenolics and flavonoids contents were assessed. Anti-hyperglycaemic activities of PMM3 was evaluated on Streptozotocin induced (50mg/kg, i.v) diabetic rats. PMM3 (50-150 mg/kg, p.o) exhibited best potentiality in reducing blood glucose within 14 days treatment in comparison with Diabecon® (Himalaya, India) at the same dose. The preset observation identified formulation PMM3 for anti-hyperglycaemic effect
