My friend's daughter had a terrible staph infection on her leg. Her friend told her to cut the onion in half, microwave it for about a minute and put it on the infected area. She did that for about 20 minutes 3x in one day and the infection cleared up.

My daughter got Cellulitus on her head recently. I did the same thing and it seems to be working. The swelling has gone down and now there is only a scab where the infection started.

It may be an old wives tale, but it seems to have worked.
