Pharmacognostical study of the root of Onosma echioides Linn

Pharmacognostical study of the root of Onosma echioides Linn

Jour Sci And Indust Res 20c(7): 218-222

The macroscopic and microscopic characters of the roots of O. echioides Linn. (Hindi-Ratanjot), a biennial hispid herb found in Kashmir and Kumaon at an altitude of 5000-9000 ft are described. The structure of the root of this plant is similar in many respects to that of the root of Alkanna tinctoria Tausch. One of the identifying characters of O. echioides root is that lysigenous cavities are often found along the medullary rays filled with a mucilagenous secretion which is stained brilliant pink with ruthenium red and blue with methylene blue.
