As a medical herbalist, I found the book useful and interesting. It covers a few herbs in reasonable depth and suggests herbs suited to certain pathogens. Many of the herbs discussed were new to me. A lot of attention is also given to the right mode of preparation of each herb. A whole chapter is dedicated to herbs to boost the immune system, a very important approach when fighting any infection.
The book is fairly chatty, with plenty of repetition. The level is suitable for the interested lay person, while practitioners will probably have to speed read over many sections. My main criticism is that the range of herbs discussed is very narrow. I would have expected an overview of the majority of known antimicrobial herbs with their respective merits. Unfortunately the book covers only about 20 plants, many of which are not commonly used by most Western medical herbalists in the UK, and as a result would be fairly hard to obtain (Cryptolepsis, Sida, Alchorna, Bidens...). Many very well established herbal antimicrobials receive no mention at all (Garlic, Tea tree, Thyme to mention but a few).
Another criticism is that, while there is a comprehensive bibliography at the end of the book, there is no referencing throughout the text, so it's pretty difficult if you want to look up the specific research behind a certain piece of information.
Overall, the book falls somewhat short of my expectations, but at the price it's still a worthwhile addition to my library.
