Studies have proven that they could be at a risk of life threatening conditions, such as invasive spasms preventing their breathing ability.

6. Blisters In The Mouth And Nostrils

Peppermint oil is akin to menthol. And, so if you are allergic to menthol, then you might probably develop blisters in your nostrils and mouth if you use peppermint oil for inhalation. Avoid any medication that has peppermint oil in its ingredient list to avoid these side effects. This is considered to be one of the major peppermint oil inhalation side effects.

Plus, the over the counter medications for acid reflux also interact with this oil in the above outlined way, with the dangers transitioning into life threatening ones.
