How Do You Make a Poultice to Draw Out Infection?

One way to make a poultice to draw out infection is to mix cornmeal and water together, boil it to make a paste, and then apply it to a boil, according to HowStuffWorks. Repeat this every two hours until the infection comes to the surface. As of 2015, there is no medical research to support this method.

In addition to making a poultice to draw out infection, other methods include using bacon, eggs, onion, milk or nutmeg, explains HowStuffWorks. To use the bacon, roll the meat in salt, and place it between two pieces of cloth. Then apply this cloth to the boil. Repeat this throughout the day until the infection comes to the surface. The white part of a boiled egg may also help to bring out the infection simply by placing the egg white on the boil and covering it with a cloth.

People also use onion to bring out infection by placing a thick slice on a boil, wrapping it in a cloth, and then changing it about every four hours until the infection comes to the surface. Mixing milk and flour with salt may also work for a boil, and people apply this poultice every 30 minutes, notes HowStuffWorks. Nutmeg helps to stimulate circulation, so using about 1/2 teaspoon in a cup of hot water as a tea can help the body fight infections.
