There is intelligence in the pages and Cunningham does know what hes talking about. Cunningham is a standard in Wiccan literature and his other books are indeed classics if not required reading for anyone on this path.
However for me this one didn't have the 'magic' of his other books, which were a joy to read, even the encyclopaedias were readable for leisure rather than just for reference.
This however was rather drab in style, though it has information there.
The book is also quite small in size (far smaller than The Magical household) and as a result it is very difficult to read as the print is rather small.
People will disagree due to his reputation but if you REALLY want to know about aromatherapy oils and their properties and uses consult a regular aromatherapy book such as the Fragrant Pharmacy by Valerie Ann Worwood or those by Patricia Davies
Learn what essential oils really are, how they really work, how they should and shouldnt be used in a general and therapeutic environment THEN think about a magical aspect, please dont skip the real understanding, these oils are very powerful.
