The plants and herbs Geralt can gather and use in are not unique to the game. Even in the first book translated to English, The Last Wish, there are mentions of numerous plants. In the short story "The Witcher", a couple are mentioned as ingredients of potions, but most of the mentions occur in the sixth part of the framing story, "The Voice of Reason" where Nenneke discusses the plants found in the grotto with the witcher and climate change in the world.
