Trans-Himalayan region has been a major component of the India’s opulent medicinal plant heritage that encompasses numerous critically endangered plant species. Arnebia euchroma (Royle ex Benth.) Johnston (common name: Ratanjot), a Trans- Himalayan native, is amongst them, and it belongs to the family Boraginaceae. Ratanjot has long been used as a colourant in food and cosmetics besides a major ingredient of traditional remedies prescribed for curing mild constipation, dermatitis, frostbite, and eczema like health disorders. Though principally harvested for its roots, almost all the parts of this plant have been used in pharmaceutical products, food, dyes and beverages since prehistoric times. Its roots are a rich source of naphthoquinone pigment(s) mainly shikonin, acetylshikonin and deoxyshikonin, accountable for its medicinal value as antimicrobial, wound healing, anti-inflammatory, anticancer, and antioxidant agent(s). Considering the medicinal importance and critically endangered status of this taxon, the need of the hour is to conserve and propagate it for supplying sufficient raw materials for its commercial exploitation.

Keywords: Arnebia euchroma, Ratanjot, medicinal prominence, shikonin, critically endangered, medicinal plant.
