Sumo 0.25% Ointment is a Moist Exposed Burn Ointment which has been developed for providing Moist Exposed Burn Therapy (MEBT). MEBT was introduced into medical practice since two decades in China. The concept of this therapy is to expose the wound to a physiological moist environment to enhance natural healing processes, whereby keratinocytes migration, angiogenesis and interaction with growth factors are facilitated.
