What makes leeches so interesting? In Russian tradition, the restorative benefits are seen in the venom. The venom contains a natural anticoagulant prescribed as a preventive treatment for stroke and heart disease.

Some choose leeches for cost savings and to avoid taking painkillers. They want something natural, to minimize the chemicals. Additionally, others apply them to treat glaucoma, prostatitis, hypertension and many more ailments. One doctor encourages patients to use them in conjunction with standard drug treatments. As they engorge themselves with blood, the creatures bulge to six to seven times their original size before dropping off.
