Leech therapy has been used for centuries for improving blood circulation. Leech saliva contains blood-thinning enzymes (hirudin, coalin, etc) which have a powerful anti-coagulating effect. For example, hirudin is the most studied component of leech saliva. It is a natural anticoagulant / blood-thinner and is ten times stronger than heparin, therefore it can help prevent unhealthy blood clotting, reduce blood viscosity and promote macro- and micro circulation. This health beneficial quality of leeches is especially useful for post-Covid cardiovascular complications to help people with any Covid related blood clotting.
Apyrase – cleans blood vessels by dissolving cholesterol plaques on vessel walls and prevents arteries from hardening. Hualuronidase smoothes the inner walls of blood vessels which helps the blood flow. It also improves microcirculation by promoting the formation of new capillaries (!!). Histamine-like substances in leech saliva have antispasmodic effect thanks to vasodilator agent that causes arteries to dilate which eases the blood flow. All of these unique saliva properties combined with the mechanical drainage of congested blood from the site allow leeches to improve blood circulation in patient’s body within a short period of time.
