Leech therapy, also known as Jalaukavacharana in Ayurveda, is an age-old healing technique that continues to be practiced today, especially for conditions like varicose veins. This method involves the application of medicinal leeches to draw out impure or stagnant blood, believed to alleviate pain and inflammation. The ancient Ayurvedic text Sushruta Samhita details this process extensively, highlighting its use in treating a range of ailments. Leech saliva contains hirudin, a powerful anticoagulant peptide that contributes to its healing effects. Dr. Megha Unnikrishnan, an Ayurvedic physician, confirms the therapy’s usefulness in skin disorders, joint issues, metabolic diseases, and venous ulcers, among others.
The procedure for treating varicose veins through this method involves cleaning the affected area, making minor pricks to initiate blood flow, and allowing sterilized leeches to suck out the stagnant blood for nearly an hour. Once they’re engorged, they either fall off naturally or are removed gently using turmeric, which also induces them to release the ingested blood. The leeches are then released into freshwater bodies. Only specific species such as Hirudo medicinalis and Macrobdella decora are considered safe for medical use. While proponents of Ayurveda believe in the therapy’s efficacy, it is often viewed as complementary rather than curative in mainstream healthcare.
However, experts in modern medicine like Dr. Rajeev Rajendran caution that removing stagnant blood does not resolve the root cause of varicose veins, which is typically weakened valves in the veins. According to him, unless the malfunctioning valves are treated through surgical intervention, laser treatment, or sclerotherapy, the condition may recur. Compression stockings and early intervention play a vital role in managing symptoms and preventing complications. Though leech therapy offers potential relief, especially in traditional systems, it is not seen as a standalone solution by allopathic practitioners, highlighting the importance of integrating ancient wisdom with evidence-based modern treatments
