I bought this some time ago and forgot to come back and say something about it.

If you are looking for a medicinal reference or a collection of herbs all set up for a specific game system, you won't appreciate this collection of herbs at all. If, on the other hand, you are looking for a collection of herbs with notes on how they were used and some folklore references to more fantastical properties so that you can incorporate the herbs as you see fit in any system, then you will appreciate this collection. I think it was well done, and am definitely incorporating aspects inspired from this into my games.
