Peppermint Oil – Benefits, Side Effects & Uses

by ThankMeNow Editors on Sep 10, 2025
Peppermint Oil (Mentha Piperita Oil) is an oil-soluble, extremely potent essential oil characterized by its high concentration of Menthol, Menthone, and volatile Monoterpenes, giving it a powerful cooling sensation and strong antimicrobial properties.

It is best used for its sensory benefits, providing intense cooling (up to 92% reported) and invigorating aromatherapy in rinse-off formulas, scalp care, or foot products, but is not suitable for sensitive, barrier-damaged, or reactive skin.
