Stephen's book on beers is great because you learn about brewing, other cultures (human), and herbs. He is also very clear about how powerful plants can be, and for each herb he gives 2-5 paragraphs of well cited information. Some of the measurements are a little vague or confusing in the recipes but like he says the point is to make a mess and have fun. This is a great read for anyone into health as well, just for the chapter on fermented honey and bee products alone. And if he includes a recipe with jimson weed or henbane, he is very clear about the inherent risks. Lighten up and drink some meade.
