I'm pretty sure this author got her start in "herbalism" from an Essential Oils MLM. The author has not learned from/apprenticed to any herbalists. She read books, googled and "did her own research" to compile this book, but at no time was advised by any certified/educated herbalist. She prescribes practices that truly educated practitioners of herbal medicine would deem extremely harmful and unsafe.
As anyone who wants to learn more about traditional herbal medicine knows, there is SO MUCH to know. And it is vital to learn from someone who ACTUALLY knows what they are talking about, who has learned from the generations before them, who have studied in communities and participated in apprenticeships. Because it IS medicine, and I am sorry, but I would never take advice from an MD who just read some books and Googled their way to their degree. So WHY would I do this with herbal medicine? Learning from actual practitioners, not "homesteaders" with a computer, is important.
The best thing about this book is her list of titles that she read to create the book. I will read those. And continue to educate myself from reputable resources for my own personal knowledge.
