5. Chamomile Tea Bag
A chamomile tea bag is actually made up of a selection of daisy-like plant products. These products are generally soothing and are very regularly used to help induce a relaxed state of mind, especially before bed.
As it happens, this is partly thanks to a chemical compound found in chamomile called bisabolol, or sometimes levomenol. This compound acts as an anti-inflammatory agent and thus it can help to sooth the are and reduce the swelling.
You can either try placing a lukewarm teabag directly on the canker sore, or simply drink the brew and occasionally swill it around the affected area.
