Peppermint essential oil is extracted from the leaves of the small herbaceous peppermint plant. Native to the moist habitats of Europe and the Middle East, this thin oil has a strong minty scent that is uplifting and energizing to the mind. When inhaled, this oil can act as a temporary decongestant for the respiratory tract. Due to the presence of menthol, peppermint essential oil has a cooling sensation that eases muscular aches and reduces inflammation.
