One of my coworkers had a hysterectomy and the site got badly infected. Her doc took out the stitches and had her pack the wound with honey (plain ol' off the shelf honey). The sugars concentrated in honey dehydrate and kill bacteria. She changed the wound packing every day, and said she could watch it healing from the bottom up.

We had a dermatologist in town who had folks pack excision sites with plain ol' table sugar for the same reason.
