It seems like there is always one more use for onion that you've never heard about before. This is a home remedy that I've seen work. It's easy and so, worth a try.
Under this waterproof bandage is a small piece of onion being used to draw cyst-like fluid from under the skin. I've seen this work on splinters, warts and solid nodules after a few applications.
You can simply put a piece of onion on the skin or you can chop it fine to put more moisture and benefits onto the area. It's not surgery, so you can't expect immediate change. Nature takes a big longer while it is working in harmony with your body.
Other onion magic claims include:
Absorbing the smell of fresh paint
Improving arthritis pain
Improving bone density
South insect sting or bite
Absorbs flu, cold and fever germs when cut and left open
