Parijat Essential Oil, is steam distilled from the flowers of the Nyctanthes arbor-tristis shrub, also called the Night-flowering Jasmine or Coral Jasmine, native to India where it is revered, it grows as a shrub or small tree and produces small star-shaped blooms that are white with orange centers and smell like honey. The flowers open at night and fall by the next morning but the profusion of bloom is so abundant that they are hardly ever without a flower during their blooming cycle.

Parijat is also known as Harshiangar and as Night-flowering Jasmine because its flowers appear dull during the daytime but turn magnificently bright during the night. It is the official flower of the West Bengal state of India where it is also referred to as Parijat. It is also known as the Tree of sorrow and the word "arbor-tristis" means sad tree; because the flowers lose their brightness during the daytime. The entire tree including its leaves, flowers, bark, seeds, and stem is known to have amazing medicinal properties for which the tree has been used in various traditional and alternative healing methodologies for more than thousands of years.
