HOME REMEDY FOR CANCER SORES

Canker sores have plagued mankind throughout recorded history.” That’s the opening line to a new study published in the latest issue of Quintessence International.
ALUM POWDER-Place a small amount of alum powder directly onto the canker sore. Allow it to sit for one full minute. Remember, it will not taste good, it is very bitter. Do not swallow! After the minute is up spit out the saliva and alum, but do not rinse with water. Within several minutes up to 24 hours your pain should be completely gone.
The ulcer may stay in your mouth for a day or two, but the pain should be gone. If for some reason the pain does not give it another try.
Like nutmeg and cinnamon, ingesting one ounce or more of alum is considered toxic to humans.
So only use a small dab!

2. Essential oils

Use 1 drop of Melaleuca or oregano essential oil, only one drop directly onto the sore.

3. Honey

Rub a small amount of honey onto the canker sore, with your mouth open let the honey sit for two minutes. Spit out, but do not rinse. Repeat 2-3 times daily.

4. Goldenseal

Mix ½ tsp goldenseal, ¼ Tsp of salt, and one cup of warm water together. Gargle with some of the mixture 3 times daily.

5. Chamomile Tea Bag

Soak a chamomile tea bag in water for one minute, after soaking place it directly against the sore for 5-10 minutes. Do this twice daily to help relieve discomfort and to speed healing.

6. Coconut Oil

Using a cotton swab, dab a liberal amount of coconut oil onto the sore. Try to get a pretty thick layer over the sore. If you feel like you can’t get it to stick melt some down with a little beeswax to thicken it.
