I haven't read that book, but I do highly recommend Dr Tilgner's
Herbal Medicine From the Heart of the Earth and
Herbal ABCs. She's done giveaways with us twice and really shared some fantastic info with us. You can find her profile here (
https://permies.com/u/149820/Sharol-Tilgner) and look through the nearly 200 posts she's made here on permies to see if it's the sort of thing you're looking for.
Her two books are invaluable resources for me.
Herbal ABCs goes ailment by ailment, offering treatments and herbs that help with each. It's organized by the different systems of the body, so it's really easy to look up issues and find remedies.
Herbal Medicine From the Heart of the Earth Lists herbs alphabetically and covers their side effects, advantages, how to use them, and tons of medical studies. It's very easy to look up something you're taking or thinking of taking and see if it's a good idea.
You can read my reviews on both books by following the above links I really, really love these books (and no, I don't get a kickback for referring them, or anything. I just really am grateful I have them!)
