Hamdard Qurs Kushta Sadaf is an Unani herbal formulation. It is beneficial in male debilities and female diseases. Kushtajat is prepared from purified drugs of mineral, metal and animal origin by the process of Ghusle Advia (purification), Tasfiya (cleaning) and Tadbeer-e-Advia (detoxification). Thereafter, these drugs are generally powdered finely and burnt in closed crucibles in pits of different size, having varying number of dung cakes and different intensity of heat for calcination. These calcined powdered drugs are called Kushtajat (Calx).
