Devon gives thoughtful guidance on how to grow medicinal herbs, and introduces us to herbs that may be growing right in our own backyards or in our neighborhoods, and yes, we are taught how to harvest wild herbs ethically and safely. The book is cleverly divided into landscapes illustrated with monographs of the plants that grow  in each: the forest, grasslands, and marsh. There are also easy herbal recipes that follow each thorough plant monograph. We also learn about all the different types of herbal preparations, from teas to lotions, and how to make them.
