Aloe is a wonderful thing for burns or skin abrasions of any kind. Mannatech, the company that makes Manapol for immune support, makes a terrific product for the treatment of burns received from radiation therapy. The best topical aloe available retail that I've ever found is George's Aloe, made near Waco. If you can find some, get it. It's great. I'm pretty sure Whole Foods carries it now.
With burns, the danger of infection is always a worry. So watch for that and take action immediately if you see any sign of infection setting in. It might not hurt to take a short regimen of oral aloe, as well as some garlic which is a natural antibiotic. Of course, taking a good aloe product orally on a regular basis isn't a bad idea anyway.
Good luck and hope you get better soon. OUCH!
