Home remedies for Canker Sores


Thanks to their anti-inflammatory and antibiotic properties, these natural remedies stop the proliferation of germs which, in the case of a weakened immune system, can lead to the formation of canker sores.

Aphthae are small, whitish, red-edged superficial ulcers that usually form in the inner lining of the cheeks, tongue, or palate. Fortunately, there are many remedies for canker sores that you can safely make at home.
