Also, researchers conducted many experiments with the saliva of a medical leech. As it turned out, it, in addition to everything, has excellent antiseptic properties. Saliva extract works in contact with our body as an antibiotic, but, at the same time, it does not have any side effects, which very often happens with medications.
The properties of leech enzymes are due to the existence of this species in nature:
1) Supporting immunity and affecting the pathogenic microflora, they disinfect the food, thereby protecting the leech from microbes. These enzymes act as antibiotics and immunostimulants.
2) Affect the walls of our vessels with you, so that the leech is easier to gnaw at. These enzymes have antiatherosclerotic and anti-ischemic effects.
3) And, finally, those that affect human blood dilute it, thereby facilitating the work of the leech and allowing it to consume blood in large quantities. There is a lymphogenous and hypotensive effect.
But, what is especially interesting, in most of these enzymes, the leech itself does not need much. Apparently, in the process of evolution, for the successful operation of the system itself, the host parasite in the leech organism was organized and the production of these unique substances was organized. And all these enzymes with their miraculous properties proved to be invaluable to humans.
