Plants

From publisher blurb: Fantasy worlds are filled with horrors beyond reality and imagination, but not every mystery an adventurer encounters is a dangerous one. In a world where magic exists and permeates the ecosystem, even the ordinary life of the world can do amazing things. Savvy rangers and druids have always known that eating certain plants, at certain times is every bit as effective as any man-made potion. The world’s most prosperous mages and hedge wizards make a good living selling the strange fruit of their even stranger gardens.
