Peppermint (Mentha piperita) oil is the second most popular essential oil in the United States, following lavender. It is cooling to the skin and gives off a fresh, grassy aroma. Peppermint is believed to be native to the Mediterranean region, although the actual origin is uncertain. The crossing of its two, parent species — mentha and peperita — occurred in the wild. Quick use: Add a few drops of peppermint essential oil to aloe vera gel for a post-sun cooling skin care oil. What's the difference between organic peppermint essential oil and conventional peppermint essential oil? Organic essential oils differ from conventional oils in that the botanicals from which they are derived are grown according to the USDA's Organic Standards. Our manufacturing facility and all of our organic essential oils have also been certified organic by the established third-party certifier, Quality Assurance International (QAI).
