Canker sores, small but painful ulcers inside the mouth or on the lips, often stem from stress, fatigue, food allergies (like nuts, cheese, or spices), or hormonal shifts. They typically heal in 1-2 weeks without intervention, but their discomfort can be significant. As experienced natural health advocates, we've compiled reliable, time-tested remedies to ease pain and speed recovery.
