It’s that simple. I used it for my sting ray wound that didn’t heal for 5 months. After 3 days of dry granulated sugar sprinkled onto the wound on my foot it started healing. This after those high $$ wound treatments and surgery. The sugar worked. Sprinkle it in ( liberally) the wound, cover with a bandage and change frequently, oh every 8 hours or so.
Thanks, as someone who has to largely self treat, I like picking up a useful treatment for wounds.
