Place an Onion Ring on the Boiler
This might feel weird, but it works. Onions have a natural antibiotic substance called allicin [6] which is responsible for the strong smell that can make one cry.
Onions have a natural absorption characteristic that can remove pus out of boils. Onions can also help to generate heat, enhance blood circulation and increase the body’s natural ability to heal wounds.
You can slice an onion into thick portions, fold a slice in gauze and place it in the boil for at least an hour. You can do this once or twice a day until the boil is gone. It is important to not use onions excessively because they can cause rashes.
