De-Mentholised Peppermint Oil (DMO) is a derivative of peppermint oil (Mentha piperita) from which a significant portion of menthol has been removed. This process results in an oil with a milder aroma and flavor, while retaining the characteristic minty notes. It is used in various applications, including flavoring, pharmaceuticals, and aromatherapy.
