Ailment: Canker sore

Remedy: Milk of magnesia

Milk of magnesia is made from magnesium hydroxide. When suspended in water it looks like milk. Magnesium hydroxide is a common component of antacids and laxatives.

Warning: when taken internally, it can deplete the body's supply of potassium and other minerals, so should only be used for a limited period.

Using a cotton bud, dab a little milk of magnesia directly into the pit of the canker. Hold it for a few minutes so that saliva does not wash it away
