Lead acetate, also known as lead acetate, has some records in ancient medical applications. Its medicinal uses are quite extensive. In terms of swelling and poisoning of sores, it is often used to make use of its astringent properties and apply it to the affected area to help the sore converge, reduce exudation, and promote healing. For some skin itching diseases, the medicine made from it can relieve the itching feeling. In addition, in some internal bleeding diseases, the appropriate use of lead acetate, with its coagulation effect, can play a certain role in stopping bleeding. However, lead acetate contains lead, which is highly toxic, and improper use can easily cause lead poisoning, damage to human organs, especially important organs such as liver and kidney. Therefore, ancient physicians were extremely cautious in their application, strictly controlling the dosage and usage, and striving to take advantage of its medicinal properties to avoid its toxicity.
