Gokshura is a well-known Ayurvedic drug that is used in many preparations. Botonically it is identified as Tribulus terrestris Linn., especially the roots and fruits of the plant. But instead the fruits of another plant Pedalium murex Linn. are commonly used and the drug is frequently substituted. Pharmacognostical study has been carried out to identify the distinguishing features, both morphological and microscopic, of the fruits of Tribulus terrestris Linn. and Pedalium murex Linn. This knowledge should help reduce the problem of substitution of the genuine drug.
