The genus Swertia was founded by Linnaeus in 1753. The plant species are erect annual, biennial or perennial herbs, generally distributed in tropical to temperate Himalayas between 1,200-3,000 m. The genus Swertia contains different bitter principles which are generally the iridoids and secoiridoids. There are many species of Swertia that are sources of iridoids and secoiridoids. About 250 species occur throughout the world. Nearly 32 species occur in India of which 15 occur in N-W Himalaya. Almost all the species have medicinal properties. Important among them is S. chirata which is used as a medicinal remedy since long and is known as chirata [67, 68].
