I go to this book with most of my questions about edible/medicinal plants and it's proven extremely useful! There are a few typos and repeated sentences I've noticed, and the editor in me wants to go through the whole book and revise it. Regardless, it's a sort of bible for me. I do have a question about the entry for black cohosh that I wanted to direct to the author. It states that it's a "powerful cardiac stimulant." I've looked that up in several other books and online sources and haven't seen as much as a mention of that part. I would love to know if that was also a mistake, and if not, it'd be really good to know why it says that.
