Over 700 pages of research based safety data, including 400 essential oil profiles, over 160 pages of EO constituent safety profiles. I have a pre-order copy and will be adding information to our essential oil descriptions and blogging about specific subjects.

This is by no means a "beginner's book" or textbook about aromatherapy. However it is the most complete compilation available of current safety research, legislative limits (IFRA and EU). Every serious student, everyone producing, designing or marketing products using essential oils, everyone teaching courses in the safe and appropriate use of these powerful healing oils needs to invest in this reference. Within a few days of adding it to our research library we had already made some changes in safety recommendations on our website and in product descriptions.
