Use Essential oils
Some alcohol-based mouthwashes contain essential oils [2] which help reduce bad breath. They also possess the ability to fight bacteria. You can produce your own mouthwash with essential oils and a carrier oil, such as olive, sweet almond, and coconut.
Examples of essential oils that help fight bad breath are:
- Myrrh
- Peppermint
- Eucalyptol
- Rosemary
You can add one teaspoon of carrier oil with a drop of peppermint oil in your mouth to help eliminate bacteria, bad odor and food particles. You can buy food-grade oils at online shops. It is important to avoid mouthwashes with added sugars.
