Be fully informed about essential oil safety from an expert not affiliated with any brands!
Hi, I'm Lea - the creator of the Essential Oil Safety Classification System™—a simple, color-coded framework I developed to help you quickly understand whether an essential oil is safe to use, should be used with caution, or should be avoided.
I believe essential oil safety shouldn't require a certification to understand. That's why I created tools like the Essential Oil Safety Classification System™—to make expert-level safety information accessible to everyone.

My goal as a Certified Clinical Aromatherapist, author, and educator for more than a decade is turning complicated aromatherapy research and creating books, courses, apps, videos, podcasts, into practical, easy-to-understand tools and resources that make it easy for everyday families to use essential oils safely and confidently.

Over the years, I've had the privilege of helping more than one million families stay safe as they learn how to use essential oils with confidence. And because I don't sell essential oils, my education is completely brand-neutral. My recommendations are based on safety—not sales.

Whether you're brand new to essential oils or you've been using them for years, I'm here to help you separate fact from fiction and make informed decisions for yourself and your family.
Welcome—I'm so glad you're here! 💜
