Mouthwashes are easy to make and so cheap. It makes me wonder why they cost so much. Then there is the "fake this" and "chemically made that". Frankly I don't really want all those extra cancer causing agents in my system. Here is a mouthwash for about everyone in your family, including a Lemon pie one for those little ones. My favorite is of course the first one and the last one.
Note: Just one thing you can either add 1 teaspoon vodka or a teaspoon glycerin to each recipe and have it last a long time and no shaking. Or you can shake it when you use it and it will last about 3 months, more than enough time to use. The reason is essential oils don't mix with water without a emulsifier. Either glycerin or vodka will keep them mixed.
1 cup distilled water
7 drops peppermint essential oil
1 cup distilled, filtered, or boiled water
1 drops clove essential oil
2 drops cinnamon essential oil
4 drops orange essential oil
1 drop ginger essential oil
Mix together in a clean container. Shake before each use. Do not swallow. Store in a dark cupboard or medicine cabinet.
