The only thing I may edit, is to make sure that you use food grade peppermint oil. Granted, you don’t drink your mouthwash, you spit it out, you often accidentally swallow a little. I’m going to try this soon though. I currently use Tom’s Natural mouthwash at home, but hey! If I can make it, & it works…I don’t have to buy it!
If you try it, please write reviews & leave them in the comments here!
