I concur with you however, GSE is extremely acidic and destroys tooth enamels. Here is my home-ade mouthwash ingredients:

Original, Listerine with Thymol and alchohol as main ingredients.

Water, add 1/4 teaspoon of Baking Soda to neutralize the acidity of GSE

GSE drops.

Oil of Oregano

Mix ingredient amounts for your own tolerance.

Dentist says I have absolutely halted Gum Disease and then reversed it with this and I plan on keeping all my teeth for the duration. All my gum areas are Pink as they were when I was young.

Health and Happiness to all…
