Leech Therapy as a Complementary Approach in the Management of Chronic Venous Ulcers: Insights from Siddha Medicine

Background: Chronic venous ulcers (CVUs) represent a significant clinical challenge, characterized by persistent leg ulcers resulting from impaired venous circulation. Traditional treatments include medications and compression therapy; however, alternative approaches such as leech therapy, used in Siddha medicine, offer promising adjunctive benefits. Objective: To evaluate the effectiveness of leech therapy combined with Siddha medicine in managing CVUs and improving patient outcomes. Methods: A 48-year-old female patient with a six-year history of bilateral lower limb venous dilation, pain, ulcer formation, and hyperpigmentation was treated with leech therapy and Siddha internal and external treatments. Treatment included leech application, wound dressing, and specific Siddha medications. Clinical outcomes were assessed based on changes in ulcer appearance, symptom relief, and venous clinical severity score (VCSS). Results: The patient exhibited significant improvements, with the ulcer on the right lower limb healing, reduced discoloration, and a decrease in VCSS from severe to mild. Symptomatic relief was noted, including reduced pain, swelling, and itching. Conclusion: Leech therapy, as an adjunct to Siddha medicine, demonstrated effective wound healing and symptom management for chronic venous ulcers. The combination of leech therapy with traditional Siddha treatments offers a valuable alternative to conventional methods.
