Maharanga emodi

(Wall.) DC.

Boraginaceae


Ratanjot is the common name of a plant in India, almost certainly in the Boraginaceae family, that has medicinal properties and also yields a red dyestuff that is used in foods, cosmetics etc. The plant is commonly traded in markets through much of India. Arnebia speciosa Aitch. & Hemsl. (syn Arnebia nobilis) is probably the main source of ratanjot, though at least 15 different species share this common name and many of these also have medicinal uses and supply a similar red dye. Onosma hispida Wall. ex G.Don (often wrongly referred to as Onosma echioides) is probably often also used as a source of ratanjot and the following species in Boraginaceae are likely to be also used at times:- Alkanna tinctoria L.; Arnebia benthamii (Wall. ex G.Don) I.M.Johnst.; Arnebia euchroma (Royle) I.M.Johnst.; Arnebia hispidissima (Sieber ex Lehm.) A.DC.; Maharanga emodi (Wall.) DC.; and Onosma hookeri C.B.Clarke[
