Boils are formed by bacterial infection on the skin. Staph is the bacteria responsible for the boil. These bacteria are present on the skin and under the nose but are harmless. They become harmful when they enter the body through cut or wound.
The boil is red in color and the affected part is swollen and filled with pus. The pus that is formed inside the boil contains the infection. It is necessary for the pus to drain out to cure the boil.
There are many ways in which the pus drains out. At times the boil forms a head by itself and the pus drains out. Sometimes by following few home remedies the boils forms a head which helps in draining of pus.
These home remedies make the healing process faster. Warm compresses are very effective way of treating a boil. A soft clean cloth is dipped in warm water in which Epsom salt is mixed. This cloth is applied on the affected area. This helps in the formation of head and draining of pus thus curing the boil. The pus that drains out is highly infectious so it should be cleaned by antibiotic lotion and a cream should be applied and the affected area should be covered by a bandage.
Apart from this some herbs or spices can be applied on it in form of lotion or paste. Garlic and onion are very effective because of their antibiotic property. They are antibacterial and antifungal. They not only cure but they stop the infection from occurring again. Aloe vera can also be applied as it is also antibacterial. It has a relaxing effect when applied. Tea tree oil and castor oil are also effective when applied on the affected area.
When the boil does not respond to these treatments and continues to grow then one must see a doctor. The doctor can prescribe some medicines and surgically drain the boil. For the surgery local anesthesia is applied on the affected area. Then a cut is made on the swelling. This swelling acts as an opening through which pus drains out. After this the doctor cleans the affected area with an anti bacterial cleanser.
Then an antibiotic ointment is applied on it and it covered with a bandage. Doctor can prescribe some medicines also which should be taken regularly because they speed up the healing process. Doctor calls the patient again and again to change the bandage till the boil is fully cured.
There are boils that are absorbed by the skin. At times we see small boils on faces which disappear after some time without any treatment and at times by just giving warm compresses while some others disappear by applying ointments on them. So we can say that a boil can heal without draining.
