What is leech therapy?

Leech therapy has been around for a very long time. In this therapy, leeches pierce a person’s skin with their teeth and insert anticoagulants through their saliva. They are then allowed to extract blood for 20 to 45 minutes at a time. This equates to a relatively small amount of blood: up to 15 milliliters per leech.

In 2004, the FDA approved medical leeches as a medical device in plastic and reconstructive surgery. In the saliva of leeches, there are over 100 bioactive substances with a wide range of effects.
