Spikenard, also called nard, nardin, and muskroot, is a class of aromatic amber-colored essential oil derived from Nardostachys jatamansi, a flowering plant of the Valerian family which grows in the Himalayas of Nepal, China, and India. The oil has, since ancient times, been used as a perfume, as a medicine and in religious contexts, across a wide territory from India to Europe.
The Bible contains several references to the spikenard, in both the Old Testament and the New Testament, and it is used in Catholic iconography to represent Saint Joseph. With this meaning, Pope Francis has included the spikenard in his coat of arms.
Nardostachys jatamansi is a flowering plant of the Valerian family that grows in the Himalayas of Nepal, China, and India. The plant grows to about 1 meter (3 ft) in height and has pink, bell-shaped flowers. It is found in the altitude of about 3,000 to 5,000 m (9,800 to 16,400 ft). 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 a herbal medicine said to fight insomnia, birth difficulties, and other minor ailments.
Lavender (genus Lavandula) was also known by the ancient Greeks as nardos, nard, after the Sanskrit "narada" or "nalada".
