Boils, also known as abscesses, are defined as painful lumps filled with pus, white blood cells, and bacteria. These lumps form under the skin when one or more hair follicles becomes infected and inflamed by bacteria. Boils can develop on any part of your body. The pus inside the boil is a thick fluid made up of bacteria, dead tissues, and white blood cells. Boils usually begin as red lumps that grows larger with time and becomes more painful until the pus drains out of it.
The bacteria that causes boils is Staphylococcus, a bacteria often found under the skin and inside the nose. Boils can also be caused by insect bites or a small cut that allows bacteria to enter the body.
Boils can be easily treated at home. Here are some home remedies that can be used to treat boils:
Turmeric-Its blood purifying properties help get rid of the pus, hence the boil. Put one tablespoon turmeric powder in a bowl and mix it with warm milk or water. Drink this mixture 3 times a day for 3-4 days. Turmeric can also be mixed with ginger and made into a paste that can be applied on the boil, cover with a clean cloth after application.
Onion– Boils are caused by infection and the antiseptic properties in onions are effective for treating them. Place a slice of onion on the boil and cover it with a clean cloth. The heat generated by the onion helps treat the boil. Repeat 3-4 times a day until the boil vanishes. Source
