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 in various cultures and is gaining popularity in modern medicine. It is often used to treat conditions such as varicose veins, arthritis, and even to assist in post-surgical recovery. While it may sound unusual, many patients report positive outcomes from this natural treatment method.
