Medicinal leech therapy in venous congestion and various ulcer forms: Perspectives of Western, Persian and Indian medicine

The use of medicinal leech therapy (MLT) is the subject of many articles describing basic pharmacological principles, application procedures, or efficacy and safety of the broad range of therapeutic indications. This review is focused on the information gap between Eastern and Western medicine when medicinal leech therapy is used in wound healing. Impaired wound healing has serious consequences for patients' health in a variety of clinical conditions. Western, Persian and Indian medicine seem to apply different therapeutic approaches when using medicinal leech therapy for healing wounds. A range of review articles, single case reports and case series on the use of medicinal leech therapy in wound healing have been inspected. The various reports indicate that medicinal leech therapy has potential benefits for patients experiencing venous congestion of the skin and tissues, as well as varied types of ulcers. Such therapy is proven to have thrombolytic, anti-coagulant, blood and lymph enhancing, anti-inflammatory and pain-relieving effects. The specifics of these approaches are expected to stimulate further research on the use of medicinal leech therapy in wound healing. Although the use of medicinal leech therapy to relieve venous congestion following reconstructive and plastic surgery is well-known in Western medicine, its use in promoting wound healing in various ulcer forms, in the context of Ayurveda/Unani/Persian medicine, seems largely restricted to Asian- and Arabic spheres. The true value of medicinal leech therapy in wound healing should be elucidated by further investigations applying modern, evidence-based research methods.
