For evaluation of Churnas containing different herb parameters tested for raw material were organoleptic, physicochemical, physical, phytochemical etc. Parameters for finished product include pH, loss on drying, angle of repose, Carr’s index, Hausner’s ratio etc. HPTLC fingerprinting of Dindayal and Developed Churna were carried out as a part of evaluation. Dindayal and Developed Churna consist of C. angustifolia leaves and fruits of F. vulgare, T. ammi and T. chebula and it is used as a laxative. Results indicated that raw material of Dindayal and Developed Churna had passed through all organoleptic, physicochemical, physical, and phytochemical parameters.
