  1. Clean the wound. When an injury happens, stop and take the time to get a proper dressing on the wound. The longer you wait, the more opportunity for infections to happen. Pour clean water over the wound to remove and debris and dirt. Next, using soap and water clean the wound completely. Remove any foreign bodies in the wound and clean again. Make sure any bleeding has stopped. Pat the wound dry, so there is no moisture left.
  2. The key to applying sugar is that it has to go into the wound and stay. For abrasions or shallow cuts, you can pour sugar right onto the wound. Use a concentrated amount of sugar and cover the wound. For deeper wounds, you can mix sugar with honey and apply to the injury. The honey will make it stick, and the sugar will still work its magic. In any case, make sure the sugar will stay in place. A study on the types of sugar and the amounts to use found that with small amounts of sugar, bacteria can still grow. However, high concentrations of granular sugar in the wound completely inhibited bacteria from growing. The Journal of Diabetes Science and Technology confirmed the results of the first study.
  3. Place a bandage or dressing over the wound. Seal the bandage with tape to keep out any impurities or debris and keep any bacteria from coming in contact with the wound. The bandage will also hold the sugar in place. The bandage should be secure, but not too tight as to restrict blood flow.
  4. Change the bandage at least daily. The bandage needs to be removed in a fast, ripping action. While briefly uncomfortable for the injured, but this motion will remove dead cells around the wound. By clearing the wound, it will be ready to receive the next application of sugar.
  5. Apply another round of sugar just as you did the first time. Place the sugar directly on or in the wound and hold in place by a fresh, clean bandage.
  6. Repeat the process until healed. Better yet, make an appointment with your doctor.
