Use of the medicinal leech Hirudo medicinalis in the treatment of haemotoma,an accmulation of blood within the tissues that clots to form a solid swelling. Haemotoma is usually caused by an injury (as here),by a clotting disorder of the blood or disease of the blood vessels. The leech attaches its sucker (disclike) near the injury,makes an incision & deposits an anticoagulant called hirudin mixed with saliva into the wound. Hirudin prevents the blood from clotting & in the case where a clot is already in existence,dissolves it away. Introduced into European medicine in 50 BC,the leech is still used today | |
