Leech Therapy: how does it work? Pt II

Eglin, Calin and Hirudin: active substances in hirudo therapy

Leech therapy has been known as a local elimination procedure for around 2,000 years. During blood sucking, the leeches secrete various substances that have an anti-inflammatory, blood circulation and analgesic effect.

Leeches suck blood by drilling a small wound into the skin and settling. They release many different substances with their saliva, including Hirudin, Eglin or Calin.

Hirudin has an anticoagulant effect and improves the flow properties of the blood and lymph and thus contributes to better detoxification of the whole body. It also has an antispasmodic and decongestant effect.

Eglin inhibits inflammatory processes and is pain-relieving, Calin causes the wound to be cleaned for up to 24 hours by subsequent bleeding, which is equivalent to a gentle bloodletting. This effect is deliberate, as it eliminates local metabolic waste, acids, inflammation substances etc. for hours and thus relieves the tissue.

In leech therapy, the active ingredients in the saliva of the leech are primarily used, but bite irritation and postoperative bleeding are also therapeutic aspects. Leech therapy is used for local pain - especially on joints and large muscle groups, tension, varicose veins, arthrosis, tinnitus, hearing loss, fibromyalgia and other complaints.

Leech therapy: everything explained in detail


The leech was known for its healing properties long before the Middle Ages. In medicine, leech therapy is now experiencing a renaissance.

The German word for leech, Egel, comes from the Greek word echis, which means little snake. In the Germanic tribes, their word for leech more or less corresponded to the word "healer" and for centuries was a loyal helper to doctors. The best known is the medicinal leech (Hirindo medicinalis), which is bred today for therapeutic purposes.

In the mouth of the leeches are the 3 radially arranged jaws with approx. 80 lime teeth. The leeches are placed on clean, non-creamy skin areas. Its bite is star-shaped (the patient then feels a minor pain). The so-called saliva (leech saliva) is immediately released through the opening between the teeth. This saliva contains the following previously identified active ingredients:

  • Hirudin: this main active ingredient inhibits blood clotting.
  • Calin: a substance in the saliva that is also responsible for blood clotting causes the wound to bleed again, which has a cleaning function and can be compared to a gentle bloodletting.
  • Egline: anti-inflammatory, hyaluronidase; antibiotic.
  • Collagenase: inhibits platelet aggregation.

Furthermore, there are other, unidentified substances in the saliva that make up the unique cocktail of active ingredients.

The average suction time of the leech is about 30-60 min., Max. up to 2 hours. Each leech drinks approximately 8-10 cc of blood. The leeches then let go and slide off. Now the bleeding takes place (about the same amount of blood again). The small wounds become substances such as Histamine washed out, which guarantee a quick healing process. At the same time, congestion is released, muscle and skin tensions are reduced, pain and pressure sensation at the affected areas is reduced. Metabolic processes are also stimulated, which results in detoxification and purification of the organism and thus stimulation of the self-healing powers. Bleeding, which can last up to 24 hours after treatment, should not be prevented. In exceptional cases, a light suction bandage is applied.

The gentle bloodletting is used for diseases of the musculoskeletal system and all inflammatory processes. Painful arthrosis provides pain relief and an anti-inflammatory effect. The treatment of poorly healing wounds can be supported.

The great advantage of leech treatment is that internal organs such as the liver, kidney and heart are not unnecessarily stressed as in e.g. medication over conventional pain relievers. Therefore, the therapy can also be used very well in older people.

Leech therapy should not be used for blood clotting disorders, anemia, simultaneous use of anticoagulant medication, existing immunosuppression and parallel therapy with medication containing mercury.
