The world of aromatherapy has grown exponentially in the last ten years. Availability of quality essential oils has increased, but so has the availability of adulterated oils. Solid research and evidence-based education has increased, but so has unsafe word-of-mouth advice.
Above, is just a sample of some of the better books on aromatherapy. There are a couple in on the shelf that I would not recommend, but most of these are solid. Len and Shirley Price and Jennifer Peace Rhind are my go-to authors for reliable monographs and safe effective essential oil use. To the right, is a partial view of my text books from Vintage Remedies.
My current favorite beginner level book is:
This is a fun book with plenty of ideas including a good starter list of basic monographs for essential oils, carrier oils, hydrosols, and other ingredients. It advocates safe practices such as dilution for topical application and avoidance of certain EOs in the presence of various contraindications.
