Ancient Practice
Leeching appears in the Caraka Saṃhitā and Suśruta Saṃhitā (c. 1st century CE) as a blood-purification measure to balance doshas in Ayurvedic medicine Encyclopedia Britannica. It was also described in ancient Egyptian papyri over 2,500 years ago for wound healing and skin disorders florabeauty.co.uk.
Modern Revival
In the 19th century, Galen and subsequent European physicians popularized leech-based bloodletting for various ailments.

How Leeches Remove Acne: Scientific Mechanisms
Bioactive Saliva Components
Leeches secrete hirudin, a thrombin inhibitor that thins blood and prevents clotting at the application site UHCWThe New Yorker. Their saliva also contains bdellins and eglins, protease inhibitors that reduce swelling and inflammation UHCW.
Anti-Inflammatory Effects
Salivary enzymes suppress pro-inflammatory mediators, rapidly diminishing redness and swelling around pimples amrutayucare.in. This modulation of local immune response can accelerate resolution of inflammatory acne lesions.
Antibacterial Actions
Medicinal leeches deliver antibiotic peptides that curtail growth of Staphylococcus aureus and other skin pathogens UHCW. Moreover, the blood-thinning effect flushes debris and bacteria from pores.
Enhanced Microcirculation and Toxin Removal
By unclogging congested capillaries, hirudotherapy improves oxygenation and nutrient delivery to the dermis, aiding tissue repair and detoxification UHCWPMC.
Clinical Procedure and Usage Instructions
Professional Administration
- Assessment: A qualified clinician evaluates acne severity and rules out contraindications (e.g., haemophilia, anemia) UHCW.
- Leech Selection: Only Hirudo medicinalis from sterile suppliers are used, to minimize bacterial carriage UHCW.

Typical Treatment Session
- Duration: 30–60 minutes per session, with 2–6 leeches applied directly to acne-prone areas UHCW.
- Frequency: Sessions repeated every 24–72 hours, as determined by bleeding and skin response.
Aftercare

- Allergic Reactions: Life-threatening anaphylaxis can occur; emergency care must be immediately available PMC.
- Lack of Sterility: Wild or home-collected leeches harbor diverse pathogens, elevating sepsis risk PMC.
- Regulatory Issues: Importing or using medicinal leeches without authorization may violate wildlife and medical device laws Aric JournalFederal Register.
