Botanical Name: Coleus barbatus Mainmul
Family: mint family (Lamiaceae)
Common Name: Coleus, Gundeer, Pakhan bed, Juntiyana, Coleus barbatus Benth
Trade Name : Pathar chur
Habitat:Growing wild on the Indian plains and the lower Himalayas on sun-exposed arid and semi-arid hill slopes of Uttar Pradesh (India) where it thrives from Simla eastward to Sikkim and Bhutan, the Deccan Plateau, the Eastern Ghats, the Eastern Plateau and the rainshadow regions of the Western Ghats in India. It has also been cultivated as an ornamental plant around the world and its root is used as a spice in Thailand, Myanmar and throughout Southeastern Asia. Makandi is one of 150 Coleus species commonly cultivated, but among a very few of these the roots (and to a lesser extent, the stems) of C. forskohlii are used for therapeutic purposes. In 1973, researchers first isolated the diterpene Forskolin from its roots, making it the only plant source thus far known for the substance.
It is a perennial, branched, aromatic herb. The entire plant is aromatic (whether fresh or dried). Members of the genus have square stems, branched, and the nodes are often hairy. The pale blue corolla is bilabiate, the lower lobes are elongated and concave, and it grows to a height of 30 cm to 62 cm. The roots are thick, tuberous, fasiculated, up to 20 cm long and 0.5-2.5 cm thick, and are conical, fusiform, straight and strongly aromatic. Leaves appear when the plant becomes pubescent, and are narrowed into petioles. Flowers vary from a very showy bluish to pale lavender. Racemes are perfect, the calyx is fine toothed and deflexed in the front. The plant possesses four parted ovaries. The leaves and tubers have quite different odors, the latter being reminiscent of ginger.

Coleus barbatus (C. forskohlii) is used medicinally in Africa, Arabia, and Brazil. The root tubers of the plant are prepared and eaten as a condiment in India. Other Indian Coleus spp. are used in traditional Ayurvedic healing. Chemical studies of alcoholic extracts of the tubers of C. barbatus led to isolation of the labdane diterpene forskolin (coleonol), which has become an important research tool in studying the roles of the enzyme adenylate cyclase and cyclic-AMP in cellular physiology. The compound may eventually become a useful drug in treating hypertension, glaucoma, asthma, and certain cancers. This article summarizes the investigations ofC. barbatus.
