Unna Boots (or Unna’s Boots) are named after the German dermatologist, Dr. Paul Gerson Unna, who developed the treatment in the late 19th century. This compression bandage provides a semi-solid mold around the foot and lower leg, applying gentle pressure while allowing movement of the limb.
Unna Boots are generally made of cotton with a zinc oxide paste applied uniformly to the entire bandage. The medicated paste may also contain calamine, acacia, glycerin, castor oil and white petrolatum. The Unna Boot keeps the wound moist to promote healing, reduces skin irritation and provides protection against infection.
