Pterocarpus marsupium, also known as Malabar kino, Indian kino tree or vijayasar, is a medium to large, deciduous tree that can grow up to 30 metres (98 ft) tall. It is native to India, Nepal, and Sri Lanka, where it occurs in parts of the Western Ghats in the Karnataka-Kerala region and also in the forests of Central India. It is also known by the names benga, bijiayasal (in western Nepal), piasal (Oriya), venkai, and many others.
Parts of the Indian kino (heartwood, leaves, flowers) have long been believed to have medicinal properties in Ayurveda. Specifically its role in diabetes.
A 2005 pharmacological study found that vijayasar extract constitutes an effective blood glucose-lowering agent and may be useful in diabetes treatment.
Alkaloid epicatechin derived from Vijaysaar is very effective in lowering the blood glucose level. Epicatechin mimics the human insulin thus is very effective against hyperglycemia
