Peppermint essential oils
You may know peppermint as menthol, its main component, but the plant has many other properties that contribute to relieving a sore throat. It works by reducing mucus congestion. In simple words, peppermint essential oils help your body by getting rid of excess mucus and thinning the secretions to make the elimination process easier and quicker.
Additionally, you may have noticed how peppermint gives you a sensation of freshness that is very hard to describe. That sensation works its way into your nervous system and helps you cope with painful sensations. It is a temporary effect, but a very pleasing one to have.
