Baking soda
Baking soda cures the armpit swelling due to contact dermatitis. It regulates the pH level of the skin, dries the wounds and reduces itching and inflammation.
Mix 1 spoon of baking soda with 3 spoons of water and prepare a solution. Apply it on your armpits and wait for a few minutes. Rinse with cold water.
Keeping it on the skin more than a few minutes will cause irritation!
