Synopsis The present compendium is first of its kind providing up-to-date information on the phytotherapeutic potential (including biological activity and active constituents) of 360 Indian plants under 288 genera and 97 families for alleviating the suffering of mankind due to diabetes. These include mostly the angiosperms (351 species), followed by pteridophytes (6 species) and gymnosperms (3 species). Of the angiospermous taxa, 312 dicotyledonus species predominate in their antidiabetic properties. Over twenty-four colour photographs of the plants, two figures and seven appendices enhance the value of the compilation significantly. It is hoped that this monographic information source will serve as a multidisciplinary ready reckoner to ethnobotany graduates and postgraduate students, researchers, pharmacists, medical practitioners, scientists and teacher through the globe.
