Onion juice

I read a couple websites claiming that onion juice was an alternative treatment. I don't really believe it, but I don't have much to lose besides a few old onions that are doing nothing but sitting in my refridgerator. I blended them together and smeared the concoction on my head. My eyes watered like there was no tomorrow. I should have anticipated this. It isn't like I've never cut onions before. I don't think the prednisone is having much effect besides depriving me of sleep. If the aloe vera does work, it won't be for a couple months. So, I'm supplementing the alternatives where and whenever I can. I won't be going sunbathing again until the current burn heals if I do try that again. Too painful!
