Leech therapy

Leech therapy has been known since ancient times. Leeches are now recognized as a medicinal remedy and are used in both human and veterinary medicine to relieve pain, reduce inflammation, and thin the blood.

The medicinal leech (Hirudo medicinalis) is bred in leech farms in various sizes specifically for use on humans and animals. An adult leech weighs four to ten gramm and can consume six to ten times its body weight in blood.

Areas of application

In small animals, leeches are used as a supportive treatment for joint inflammation, muscle stiffness, wound healing disorders, lymphatic inflammation, bruising, abscesses, nerve inflammation, and much more.

Leeches are increasingly being used on horses in both sports and leisure activities. They can provide useful support and accompaniment to therapy for laminitis, colic, eczema, scars, bruising, muscle and tendon disorders, and even vein and gum disease.

Procedure

There are a few things to remember before treatment with leeches. You must not give your animal any blood-thinning or anti-inflammatory medication three days beforehand. Leeches are very sensitive to odours. Do not feed your horse any feed supplements containing garlic, ginger or other essential oils for three days beforehand. Do not apply any ointments, insect sprays or shampoos to the skin areas to be treated two days beforehand.

The leech is placed on the desired area of the animal's skin using a laboratory tube or by hand. After a short moment, the leech attaches itself firmly, saws into the skin with its tiny teeth, and begins its blood meal. This usually lasts 30-60 minutes.

With a sufficient meal, the leech can survive for up to two years. However, to prevent the transmission of diseases, medicinal leeches are killed after treatment or returned to the leech farm, where they are placed in a "used leech tank" and are no longer used.

Mode of action

As soon as the leech bites, various substances are released into the animal's blood via its saliva, the effects of which are used for therapeutic purposes. These substances are important for the leech to be able to feed at this spot for as long as possible. It is believed that there are up to 100 different active ingredients in leech saliva, only a fraction of which have been identified and researched to date.

Initially, substances are released that accelerate the distribution of the leech saliva in the blood. These are followed by active ingredients that have pain-relieving, anti-inflammatory, and vasodilatory effects.

The bleeding from the wound after the bite is not harmful, but has a cleansing effect.
