What is Leech Therapy?
Medical Leech Therapy (MLT), also known as hirudotherapy, is a traditional healing method that uses live medicinal leeches (Hirudo medicinalis) to treat a wide range of health conditions. This form of therapy has been practiced for over 3,500 years and is now supported by modern science due to the over 100 bioactive substances found in leech saliva. These compounds include hirudin (a powerful anticoagulant), calin, hyaluronidase, anesthetics, and anti-inflammatory agents.
Today, leech therapy is used not only for treating diseases but also as a preventive treatment to maintain overall health, improve circulation, detoxify the body, and support immune function.
Pros: Top 10 Proven Benefits of Leech Therapy
1. Improves Blood Circulation and Prevents Clots
The anticoagulants in leech saliva prevent the formation of dangerous blood clots. This improves blood flow and is especially beneficial for people suffering from vascular disorders, varicose veins, and deep vein thrombosis.
2. Supports Tissue Regeneration
By enhancing blood flow to damaged areas, leech therapy is effective in microsurgery, reconstructive surgery, and burn healing. The therapy promotes oxygen delivery and speeds up the recovery of tissues and nerves.
3. Natural Pain Relief and Anti-Inflammatory Effects
Leech saliva contains natural anesthetics and anti-inflammatory enzymes, making it useful for treating arthritis, rheumatism, and joint pain without the need for synthetic drugs.
4. Promotes Skin Health and Anti-Aging
Leech therapy boosts circulation to the skin, helping with conditions like eczema, psoriasis, acne, and scars. It also enhances collagen production, giving skin a radiant, youthful glow.
5. Stimulates Hair Growth
In Ayurvedic practice, leech therapy has been used to treat alopecia areata. By improving scalp circulation and reducing inflammation, it can stimulate hair regrowth naturally.
6. Detoxifies the Body
Leeches remove toxic, stagnant blood, allowing for detoxification of heavy metals and waste products. This supports liver function, reduces fatigue, and promotes a feeling of rejuvenation.
7. Regulates Blood Pressure
Thanks to its antihypertensive effects, leech therapy helps regulate blood pressure naturally, improving cardiovascular health and reducing the risk of heart attacks or strokes.
8. Supports Mental Health
Leech therapy has anxiolytic (anti-anxiety) properties that help relieve stress, depression, and anxiety disorders. Improved blood flow to the brain also enhances mood and mental clarity.
9. Boosts the Immune System
Leech saliva contains immune modulators that help balance the body’s immune responses. It can strengthen the body’s ability to fight infections and inflammation.
10. Enhances Digestive and Organ Function
By stimulating blood flow to vital organs like the liver, kidneys, and digestive system, leech therapy supports their optimal function and promotes internal homeostasis.

FAQS
How does leech therapy work?
Leech therapy’s effects can be grouped into three interrelated mechanisms:
1. Active Suction
Leeches attach using anterior and posterior suckers, creating a strong vacuum that draws out congested blood. This mechanical drainage immediately relieves venous hypertension and tissue edema. As they feed (usually 20–60 mL over 10–20 minutes), they remove stagnant blood, reducing pressure in compromised microvasculature
2. Secretion of Vasoactive and Bioactive Substances
While feeding, leeches inject saliva containing dozens of potent compounds:
Hirudin: a direct thrombin inhibitor that prevents fibrin formation and clotting
Calin: blocks platelet aggregation, extending bleeding
Hyaluronidase: increases tissue permeability, allowing deeper diffusion of saliva components
Histamine-like vasodilators: open capillaries to boost local blood flow
Analgesic peptides: numb the bite site, so patients often feel little to no pain
Protease inhibitors (eg, eglins, bdellins): reduce inflammation by blocking inflammatory enzymes
These secretions act synergistically to maintain perfusion, limit inflammation, and manage pain throughout and after therapy
3. Passive Oozing
Once the leech detaches—either naturally or under practitioner control—the bite site continues to ooze blood for up to 2–3 hours. This prolonged bleeding, maintained by hirudin and calin, further decongests tissues and sustains oxygen delivery during early wound healing
Are leeches good for you?
While the scientific community generally doubts many of the claims made by contemporary advocates of leech therapy, there are compelling reasons to continue researching their potential uses.
Is leech therapy still used?
Yes, leech therapy remains in use today. Initially overshadowed by the debunking of the four humors theory in favor of germ theory, leeches regained attention in the 1970s when healthcare providers recognized their ability to assist in specific surgical procedures.
Leeches possess numerous tiny, needle-sharp teeth that enable them to attach swiftly to skin and tissue. Their saliva contains potent anticoagulant properties similar to antiplatelet medications such as aspirin, which reduces inflammation and promotes proper blood circulation around the leech bite. This is especially advantageous in surgeries involving the reattachment of severed or amputated body parts, as well as in skin graft procedures. Today, leech therapy is sometimes referred to as hirudotherapy, named after the species of medical leeches, hirudo medicinalis.

Leech therapy before and after?
What is the self treating with leeches?
When treating yourself for a leech bite, it’s important to remove the leech safely to avoid complications. Here’s what you should do:
- Locate the leech and check for others: First, find where the leech is attached and check for any additional leeches on your body.
- Identify the head and mouth: The head is typically smaller and narrower than the rest of the leech’s body and is the part attached to your skin.
- Tighten the skin: Gently pull the skin under the leech to make it taut.
- Remove the leech: Slide a fingernail, a piece of paper, or a credit card under the leech’s mouth to loosen its grip. Once it’s detached, flick the leech away.
- Treat the wound: After removal, clean the bite with rubbing alcohol or another first-aid solution to prevent infection, then bandage the wound. Be prepared for some bleeding, and change the bandage until it stops.
You can also allow the leech to fall off naturally, which may take 30–45 minutes, but if it’s in a difficult spot, you may need professional help.
Avoid harmful methods like using salt, fire, or chemicals, as these can cause the leech to regurgitate, increasing the risk of infection.
How does hirudin contribute to anticoagulation?
Hirudin binds directly to thrombin’s active site, preventing fibrin formation and thereby maintaining blood fluidity at the bite site. This localized anticoagulation allows continued bleeding after leech removal, ensuring sustained perfusion of the treated area.
