Spikenard (Nardostachys jatamansi); also called nard, nardin, and muskroot is a flowering plant of the Valerian family that grows in the Himalayas of Nepal, China, and India. It is used in the manufacture of an intensely aromatic amber-colored essential oil. The oil has, since ancient times, been used as a perfume, as a medicine and in religious contexts, particularly in connection with historical Judaism.
The Bible contains several references to the spikenard, 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.
