Hirudotherapy is a medical treatment that uses leeches to promote healing. The leeches are applied to the skin, where they attach and release saliva containing beneficial substances. These substances can help improve blood circulation, reduce inflammation, and promote tissue regeneration. This therapy has been used for centuries and is often employed in modern medicine for various conditions, including varicose veins, arthritis, and post-surgical recovery. While it may sound unusual, many patients report positive outcomes, making hirudotherapy a valuable alternative treatment option in certain cases.
