Leech Farm

An employee of the International Medical Leech Centre demonstrates with a leech on her face in the village of Udelnaya, some 30 km (18.6 miles) from Moscow, December 4, 2009. The leech farm makes a tidy profit shipping them to doctors worldwide. Like many discarded elements of traditional medicine, they have made a come-back as doctors have re-discovered their pain-killing properties, which come from the chemicals they inject into the skin when they bite it. Several medical trials have proven leeches help relieve the symptoms of arthritis and other conditions. REUTERS/Denis Sinyakov (RUSSIA HEALTH SOCIETY)
