Very simple guide to poisoning for anyone who's writing a novel, short story, or simply wants to add some realism to their fictional game worlds. I spent ages Google searching the effects of various plants/medicines/etc. while writing a segment about poisons for a game project I was working on before a friend pointed me toward this book. It gave me the answers that I needed quickly and in an easy-to-read format. 10/10 would recommend to fellow writers.
