than standard capsule) bull Flagellation For treating arthritic joints whipping with fresh mature nettles will

stimulate circulation to the swollen area relieve pain and greatly increase freedom of movement Although some people cannot tolerate this heroic therapy others find that the initial shock gives way to a pleasant buzzing sensation followed by 2 or more days of freedom from pain and inflammation This therapy should be approached with circumspection
