Essential Oil Safety Textbook

by Robert Tisserand & Rodney Young

Essential Oil Safety provides a rational basis for an analysis of hazards and risks based on current scientific understanding of their biological actions. The 600 newly structured and extended Profiles (either of essential oils or constituents) provide the only comprehensive, evidence-based guidance currently in publication to safe formulations and use of an encyclopedic range of essential oils.

For the first time, the potential for interactions between essential oils and orthodox drugs is reviewed with insights into this important area of essential oil safety. With the increasing use of both conventional medications and essential oils, this provides particularly valuable insights for practitioners, health providers, spa workers, and product manufacturers.

What Our Students Say About Us

Robert was organized, knowledgeable and detailed. He answered all questions to the best of his ability and provided a wealth of information. I recommend his class. I will be blending more effectively, and with greater confidence from today on!

Laura Murphy-Waters

Thank you for your inspiration and your contributions to the holism and science of aromatherapy. We wouldn’t be where we are today without you.

Deborah Halverson

*WOW* I just finished watching the first webinar “Healing Oils” from Robert Tisserand’s skin series. SOOOO impressed!!!! I love that he is super easy to listen to, easy to understand, and has lots of references. I learned SOOOO much in that 35 minutes! Another thing I love is that there is a PDF to print with most of the slides used in the presentation, so I can scribble notes around and to the side of them for referencing later.


Robert has this amazing ability to make things sounds so simple and basic, and yet you walk away with a deeper level of knowledge and understanding. I don’t know how he does it! Brilliant.

Lea Harris, owner, Learning About Essential Oils

Not only was the information presented indispensable, Robert communicated a contagious enthusiasm for the topic of aromatherapy. I came out with more questions than answers and the burning desire to learn more.

Linda Mireler

Thank you for all you have done for our profession.

Donna Whyte English

The Skin series are my stable source for almost everything related with esthetics and EOs. The more you listen the more you are fascinated with new data that you didn’t realize at the beginning. Each sentence there contains a lot of information that you wouldn’t otherwise find in such an accessible way. For me this is a treasure because I find answers to many questions that nobody else is able to answer and I can improve my work.

Begona Sanchez

Thank you, Robert, for inspiring my aromatherapy journey and College with your three important books.

Elizabeth Jones

Thank you for your inspiration and your contributions to the holism and science of aromatherapy. We wouldn’t be where we are today without you.

Deborah Halverson

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.

Nancy Graves

Robert has a wealth of knowledge about essential oils that is unsurpassed. A seminar with him is like a whole course condensed into a weekend.
