Cunningham's Encyclopedia of Magical Herbs

The collection feels very thorough but also personal. I wonder what criteria or sources influenced his selections and descriptions.

The detailed associations between herbs and magic traditions made me rethink how I incorporate plants into rituals. What herbs have others found most effective or meaningful?

The way the book is structured makes it easy to reference different herbs, but I'm curious whether this was based on Cunningham's personal workflow or standard reference practices.
