I do not even know where to start with my experience with Aromahead Institute. I have loved every part of the courses. They really have thought of every angle on how to teach the material and to make it fun and not overwhelming. I appreciate how much research and scientific information that Andrea and Cindy have compiled for us. The other instructors have also been very helpful and encouraging. What was surprising to me was how many researchers have done tests on the components and on specific essential oils for diseases. Great learning tools! Thanks Aromahead for your hard work and knowledge.
