Antimony sodium tartrate, also known as tartar emetic, is primarily used in medical applications as an antiparasitic agent, particularly in the historical treatment of schistosomiasis (bilharzia), a disease caused by parasitic flatworms (trematodes) transmitted through contact with contaminated freshwater. It works by interfering with the parasite's metabolism, effectively killing it. Additionally, it has been used in veterinary medicine to treat similar parasitic infections in animals. In industrial settings, this compound is utilized in the manufacturing of certain types of glass and ceramics, where it acts as a fining agent to remove bubbles and improve clarity. It is also employed in the textile industry as a mordant to help fix dyes to fabrics, ensuring colorfastness. Note: Due to toxicity concerns, its medical use has largely been replaced by safer alternatives.
