Essential Oil Safety Pages
The Tisserand Safety Pages include safety guidelines, a database of adverse reactions, and other resources related to the safe use of essential oils. The essential oil in a bottle is 50-100 times more concentrated than in the plant, and safety issues apply to essential oils that may not apply to the whole plant or herbal extract. The rise in popularity of essential oils together with, very often, insufficient information on safety precautions in using them, coincides with an increased prevalence of adverse reactions, and it is likely that these are linked.Learn About Safety

Student Testimonials”I am a botanist, science teacher and former clinical medical technologist, and I really appreciate the research summaries, the references, and your experienced interpretation of the study results. I appreciate your respect for the research and the recognition of its limitations as well. I love the calm delivery, the printable notes, the whole package. “”I thoroughly enjoyed Robert’s class. He taught me more about essential oils than I would have learned on my own in years. “”For me, Robert Tisserand is the final word on essential oils, as well as the myth buster and the advocate. He’s also the most gentle and kind presenter I have come across. “”The breadth of Robert’s knowledge in the field of essential oils is remarkable. He is a gift to those of us working with these gems of nature. But for me, even more importantly, he is an outstanding teacher; having knowledge is one thing, but being able to clearly and articulately impart it is another. He has both, and this indeed is what contributes to genius. “”I am always so grateful to study with Robert. The general information and even the slightest little details he shares are so valuable and often open up a whole new world. “
