Summary

The concept of Unani medicine is based on balancing body humours, the imbalance of which causes diseases. The application of leech therapy in medical and dental science is well recognized.

Why This Matters for Hirudotherapy

This narrative review summarizes the applications of hirudotherapy across medical and dental practice, discussing the physiological effects of leech therapy and its purported therapeutic roles in conditions including cancer, diabetes, and dental disorders, along with associated complications. As a review grounded in the Unani medical tradition of humoural balance, it is directly relevant to ASH's domain and offers a consolidated perspective on the clinical scope of leech therapy. However, the abstract indicates this is a brief narrative review rather than a systematic review or primary study, providing no original data, quantitative results, or critical appraisal of evidence quality. Therapeutic claims appear framed within the Unani paradigm without indication of evaluation through controlled clinical trials, and no specific efficacy or safety data are reported.
