Dude, as much as I love garlic, I believe it's the cayenne pepper. Capsicum (the active agent in cayenne) regulates metabolism and heals ulcers better than any spice I've tried. They are doing studies on it for treating the hardest hitting cancers. It also an appetite stimulant.
What's the heat rating of the one you are using? Try upping it to 90,000 for enhanced wound healing. Go to 180,000 if you dare.
