What Our Readers Say
Across our reader reviews, the response has been overwhelmingly positive. Readers most often describe the books as comprehensive, easy to follow, and beautifully laid out, with particular praise for the herb-pairing guidance and the plain-English notes on what not to mix with medications. Many call it the most useful herbal reference they own and a book they reach for again and again.
The only herbal book I own that actually tells me about interactions with pharmaceuticals. So much information on herbs, medicinal uses, and even beautiful pictures.
A fabulous resource. Pretty in depth, easy to navigate. I love that it's organized by ailment, and the recommendations for herbs to pair together.
Even my 4th grader gets it. It tells you what not to mix with your medications, which is super helpful, and it has real science to back it up.
What an outstanding and interesting book. There's an herb, plant, mineral or natural resource for just about everything.
Comprehensive and exhaustive: how to grow herbs, which grow well together, and how to combine them into recipes. Exactly what I was looking for.
If you're interested in herbal medicine, buy this book. Very easy to follow and understand. It's my new go-to herbal book.
This one has more information in it than all my other herbal books combined. I love the way the book is laid out.
As an MD and a botanist, this book combines both of my passions into one.
A wealth of information. User friendly, and it helps the layman step into the herbalist world. Well worth the money.

Highly recommend this book. Very informative.
