Very well organized with 52 hyper-linked chapters so you can find the right herbs for different needs. Each chapter is full of useful information about various herbs, results of research, and tips. I was just going to write that it would be better to know how to find and purchase the herbs when I found a very useful resources section at the end. I will certainly dip into this book when I have a specific ailment. I was very lucky to be able to download this book for free and for that price it's certainly worth 5 stars! If I had to pay more I'd award 4 stars as I'd probably want more features such as pictures, side boxes with recipes, and a hyper-linked index of specific herbs so that I can go from the herb to the ailment rather than ailment to herb if I want to.
