Tisserand Institute Essential Oil Safety Pages

Essential Oil Safety Pages

Essential oils can be safely used to enhance wellbeing and as part of a healthy lifestyle. They are used by millions of people every day, and mostly without any adverse incident. However, essential oils are powerful substances and can be harmful if not used with due care and diligence. 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 coincides with an increased prevalence of adverse reactions, and it is likely that these are linked.

This rise in negative reactions along with often baseless claims for treating serious disease gives aromatherapy a bad reputation and is a short-cut to increased regulation of essential oils, something that is already happening in Europe.

If safety guidelines were (a) widely disseminated and (b) followed most of these adverse events would be avoided. Which is why the Tisserand Institute brings Safety Pages, a basic roadmap to help you use essential oils in an efficient and safe manner.

Good aromatherapy practice = maximum benefits + minimum risk

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

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
