Malabar nut is an important plant in traditional Indian medicinal systems and used in the treatment of coughs, cold and other respiratory diseases. The plant emits a strong odor; it is avoided by herbivores (hence the name Adhatoda in Tamil). The plant is cultivated as a hedge cum medicinal plant in villages and farmlands. I saw it used as hedge plant in an Irula village in Nilgiri district at 1000 msl. Malabar nut is a very sturdy plant and withstand hot climatic conditions. This plant is commonly deployed as a hedge plant in rural areas of Coimbatore district. The commercial cultivation of this plant for medicinal purposes has been successful and various inter-cropping techniques with other commercial plants have been worked out.
