10 Treatments for Boils

5. Onions

While you may not instantly think of onions as an effective boil treatment, you can, in fact, use onions to get relief from the discomfort caused by the boil. The flavonoids and essential oil properties combine to remove toxins and inflammation from the boil while at the same time disinfecting the area. You can thinly slice an onion and place the slices directly over the boil. Secure the area with a bandage to keep the onion slices in place. You can also boil onions and then apply the onion water to the boil with a clean cloth.
