But did you know the medical use of leeches is still very much a thing today?The therapeutic use of leeches has been documented in ancient Indian and Greek medicinal handbooks. Where they were used for the simple purpose of bloodletting which is the practice of blood withdrawal to prevent illness and infection. The ancient thought that bloodletting was the cure to everything from fever to tuberculosis. And while bloodletting turned out to have limited efficacy, nowadays, leech therapy is still used for variety of medical condition including circulatory disorders and cardiovascular diseases. As well as different forms of cancers and arthritis. Some patients with osteoarthritis have actually even said that leeches offer more pain relief than topical medications.
