It is a flowering plant of the Valerian family that grows in the Himalayas. It is a source of a type of intensely aromatic amber-colored essential oil, spikenard. The oil has, since ancient times, been used as a perfume, as a medicine and in religious contexts. It is also called spikenard, nardin or muskroot.
It grows in the eastern Himalayas, primarily in a belt through Kumaon, Nepal, Sikkim and Bhutan. The plant grows to about 1 m in height and has pink, bell-shaped flowers. It is found in the altitude of about 3000–5000 meters. Rhizomes (underground stems) can be crushed and distilled into an intensely aromatic amber-colored essential oil, which is very thick in consistency. Nard oil is used as a perfume, an incense, a sedative, and an herbal medicine said to fight insomnia, birth difficulties, and other minor ailments.
