I love cooking spicy food which required preparation of chopped chillies. As a result, I frequently suffer from chilli burn on my fingers. However, there are a few home remedies which can help to reduce the burning sensation by using some common ingredients found in the kitchen of every home.
Washing hands with soap and water will not help to reduce the burn due to the presence of an active chemical in chillies called capsaicin which is not water soluble.
Salt - Rub a pinch of salt on the skin for a minute or two and wash it off with water. Contrary to common belief, rubbing salt is not adding salt to a wound because it does rub away the capsaicin components on the skin and eventually relieving the burning sensation. (Personal experience: 7/10)
Cooking Oil - Capsaicin are fat soluble. Just drizzle a few drops of oil and rub around affected areas and wash it off with soap and water. For me, oil or fat works best to stop the burn. (Personal experience: 9/10)
Milk - Pat the affected skin with cold milk to cool the burn and allow the capsaicin chemical to dissolve in milk fat. I'm not too keen on this because I didn't feel like wasting milk and the pain relief was only temporary. (Personal experience: 5/10)
Margarine or Butter
Margarine or Butter - Similar to cooking oil, margarine and butter contain fat which can dissolve capsaicin and remove traces of the chemical on the skin. However, this method doesn't seem to work as well as cooking oil for me. (Personal experience: 8/10)
Lime - Squeeze some lime or lemon juice and dab it around the affected area. The acidic nature of lime will act as a neutralizer for the alkaline capsaicin. I had used a combination of salt and lime juice which did result in some relief from chilli burn. (Personal experience: 7/10)
These are simple home remedies which offer great pain relief from chilli burn. Of all the 5 methods tested, cooking oil seems to work best. Alternatively, there are many other ways to reduce the burning sensation by using alcohol, syrup, toothpaste, sour cream and many others.
