To establish the pharmacognostic standards for the correct identification and standardization of an important Antidiabetic plant described in Ayurveda.Standardization was carried out on the leaf and stem of L. with the help of the macro-morphological, microscopic, physicochemical and qualitative phytochemical studies.Several specific characters were identified viz. clustered calcium oxalate crystals in the cortex region, absence of trichomes, succulent, thick, mucilaginous, fibrous stem. Rubiaceous type of stomata on both sides of the leaf. Quantitative microscopy along with physicochemical and qualitative phytochemical analysis were also established.The pharmacognostic standards could serve as the reference for the proper identification of the L. which is an important anti-diabetic plant described in Ayurveda.
