Onions have a very similar nutrient profile to garlic, which also means that it is exceptional at reducing infection and inflammation throughout the body. In the case of canker sores, the active ingredients in onions can help to shrivel and numb the site of the canker sore, making it far less intrusive when you’re trying to eat, drink or talk, and also speeding the healing process. You can slice up a raw onion and apply it directly to the site of the sore, or let onions soak in water overnight and then gargle with the resultant mixture in the morning for quick relief.
