Leech therapy, a research conducted by a German doctor Mikeson, found that blood-sucking leeches are very effective in treating knee arthritis. Compared with aspirin and other physical therapy methods, the effect of leeches therapy is very good. He once put 4 leeches on the knee of a patient with severe knee pain for 80 minutes. The patient only felt a little discomfort at the beginning, and it would get better soon. The key to the "pain reduction" of leech is that its saliva contains anti-inflammatory ingredients.
