| The first recorded clinical use of Medicinal leeches (Hirudo Medicinalis) occured approximately 2500 years ago. Since the leech's bite produces a small bleeding wound that mimics a venous circulation in an area of compromised tissue, this small invertebrate animal is particularly valuable for plastic and reconstructive surgery. The leech produces a number of important substances which contribute to the special property of the bite, including an anticoagulant, a local vasodilator and local anaesthetic. And also Medicinal leech is used in cosmetics and pharmacology. |
