Leeches in modern medicine | ANU Research School of Biology
The two-main leech species used in medicine are Hirudo medicinalis, and Hirudo verbana.

There have even been recorded cases of leeches helping with the re-attachment of severed fingers and ears. Data suggest that without leeches the success rate of …

These days, leeches are used to help heal skin grafts– the process for treating burns in which blood tissue is transferred from one part of the body to another — by removing blood pooled under the graft and restoring blood circulation in blocked veins. They’ve also been used in reattaching fingers and other body parts [sources: MSNBC, PBS].

Medicinal leech therapy—an overall perspective – PMC
When a leech bites, hyaluronidase and collagenase allow access to the tissues and blood vessels; vasodilatation occurs by the action of histamine-like molecules; platelet functions, kinin activity, and the coagulation cascade are inhibited; and inflammatory reactions are suppressed. In addition, analgesic and antimicrobial effects are observed.

Some doctors now prescribe leeches for a host of other ailments, including varicose veins, neuropathy, blocked arteries, and even osteoarthritis.

Leeches were once used for medical conditions like fevers, when that symptom was incorrectly attributed to excessive blood or an imbalance of the apocryphal four humors in a human. Based on updated medical research, their blood-draining skills are now used to clean up pooled blood in the body. When blood starts pooling instead of circulating, the area swells, and the lack of fresh, oxygenated blood causes skin tissues to die. Leeches can prevent that from happening.
