What is Cankerex?

This is a review of our #1 choice, Cankerex. The manufacturer of this natural supplement claims it provides relief for canker sore symptoms by decreasing pain and inflammation during the onset of an outbreak while reducing the time needed for healing. The product has strong antimicrobial, antiviral and antioxidant properties and contains a number of vitamins and minerals, all of which are needed by the body to fight off the canker sore as quickly as possible and prevent the from occurring again in the future.


The ingredients used for making this supplement include:

  • Aluminum Potassium Sulfate – Soothes & cleanses, removing the moisture from the sore to speed up healing.
  • Holy Basil – An extract that provides medicinal, antiviral & antimicrobial properties to heal & prevent.
  • Propolis  – An antibacterial substance produced by bees that helps reduce swelling & aids healing.
  • Licorice – Provides powerful antibacterial properties, numbing the affected area & sealing the canker sore.
  • Lysine – Boost Lysine deficiencies to suppress outbreaks & promote healing.
  • Folic Acid – Boost Folic Acid deficiencies to suppress outbreaks & promote healing.
  • Vitamin B12 – Increase vitamin B12 levels to aid prevention, provide pain relief, reduce severity & duration.


The manufacturer recommends taking a pinch of the powder in your mouth, leaving it there for a minute to a minute and a half and then spitting it out afterward. Your mouth will fill up with saliva, which you will use with the residual powder to thoroughly swish around for a couple of minutes, which, when you’ve finished, will spit out. For best results, repeat this two to three times a day. For long term use, mix a pinch of powder with some water and use it as a mouthwash one to two times a week. The manufacturer has not specified the time needed for the first result to become noticeable and how long you should use the product, but it’s reasonable to say it should be used until all the symptoms are gone and occasionally for preventive measures.


The price for one 30ml (1oz) bottle of Cankerex is $49.95. You can buy a package of two for $69.90, four for $111.80 and six bottles for just $139.80. This is a great saving for canker sore sufferers, especially as this product can be used as preventative mouthwash.
