I am getting ready to take an online aromatherapy course that offers a certificate (not CEU). I got it on ebay for $25, but on her website its $50. I haven't gotten to start it yet because the textbook and workbook has not arrived yet. But, I have already gotten her worksheets and "tests" and downloaded them. From those, it seems very thorough. Of course, this is coming from someone who knows NOTHING about aromatherapy, so anything is pretty thorough for me! lol Along with the class you get a membership to her board/group to always go to for questions, etc. The ebay id is herbnhome and her website is www.thedreamangels.com
The class is titled: 301 Aromatherapy: This course describes how to use aromatherapy as a healing tool alone or with other therapies such as herbs or homeopathy, and her name is Kristie Karima Burns, MH, ND.
When I complete the class I'll let you know what I thought of it all.
Hope that helps! - Heather in Texas
