The essential oils we carry are by Snow Lotus Aromatherapy, based out of Santa Rosa California, and owned and curated by clinically-trained Aromatherapist Peter Holmes. He has been practicing with essential oils in his Acupuncture practice for over thirty years, and teaches widely on how to use essential oils on the acupuncture points. He is also an author of a two-volume book entitled "The Energetics of Western Herbs." His essential oils are sourced from small, artisan distillers around the world and are either from organically-grown or ethically and sustainably wild-harvested plant material. These essential oils are of the highest quality and are pure, unless noted that they are sold already diluted in jojoba oil.
