Exploring the Therapeutic Potential: Ta'līq al-'Alaq (Leech Therapy) for Qarha Khabītha (Non-Healing Ulcer): A Case Study.

Non-healing ulcers are chronic lesions, often found on the lower extremities, persisting for over three months despite adequate care. They are associated with systemic diseases or local disorders and significantly impact the quality of life, often resisting conventional treatments, which can be costly and pose side effects. Ta'liq al-Alaq (leech therapy), a regimen in Ilaj-Bit-Tadbeer of Unani medicine, offers an alternative based on the principle of Istifrāgh (expulsion of morbid humours). Leeches aid by sucking impure blood (Ghalīz Mawād) and injecting saliva containing bioactive substances, enhancing blood flow, reducing local inflammation, and promoting tissue regeneration. This study assessed leech therapy's efficacy in a patient with three non-healing ulcers on bilateral lower limbs, persisting for 27 years. Leech Therapy was done once a week. Treatment progress was recorded at baseline, 2 weeks, 4 weeks, and 6 weeks, evaluating parameters like size, discharge, smell, pain, edge, and floor. Two ulcers completely healed, while the third showed partial healing after six weeks. These promising results suggest leech therapy as a viable, cost-effective treatment for chronic ulcers and thromboembolic disorders, especially when conventional methods fail. Larger clinical studies are recommended to further validate its efficacy and establish its role in modern wound care management.
