This book is more of an essential oil 101/introduction. Any side information/extra information is in purple boxes. It does seem researched well and is not brand specific. She has a section called “the top 11 essentials” - the essential oil, botanical name, information and a few recipes. It then goes to other essential oils – same go through as the other oils. The 'essential' home apothecary talks about bases, carrier oils, blending, and storage. There are sections of resources and recommended reading. It is more of a general, beginner book. But it does go through the oils people will come into contact with. And if you want more recipes than she put in – the internet then comes into play.
