Medicinal leech therapy in pain syndromes: a narrative review

Medicinal leech therapy is used in a variety of conditions; most of which have pain as a major symptom. Its mode of action relies on the injection of leech saliva into patients' tissues during the process of blood withdrawal. Leech saliva contains active ingredients with anti-inflammatory, thrombolytic, anti-coagulant and blood- and lymph-circulation enhancing properties. A specific analgesic substance within the leech saliva is yet to be identified. Pain relief from leech therapy is rapid, effective and long-lasting in many conditions. This review compiles studies and case reports that provide clinical evidence for leech therapy's analgesic effects.

Narrative review on leech therapy's analgesic effect across multiple pain syndromes (osteoarthritis, epicondylitis, hematoma, thrombophlebitis, varicose veins); the saliva contains anti-inflammatory, thrombolytic, anti-coagulant and circulation-enhancing molecules, though a specific analgesic compound has not been identified.
