Next, to help relieve the pain, gently massage castor oil into the sore area of your jaw, face and neck. Not inside your mouth, but on your face and neck. You will probably find that the pain will reduce within an hour or so.

The castor oil will penetrate to a depth of approximately 10 centimeters, so it will get into the infected area. Castor oil is antibacterial and will help to clean out the poison. It's also extremely effective as a painkiller. Sorry, I don't know why, I just know it works.

If you use the castor oil at night I would suggest wrapping your pillow in an old towel to prevent the oil from staining your bedding.
