"Any one working on the medicinal plants of Latin America and wanting to gain an insight into what research has been undertaken on a particular species will find this book essential reading. As with all the books produced by James Duke it is informative and provides a wealth of basic information. ... The power of this book is in the electronic version where the data are searchable, and it is easy to link many of the references to their sources such as PubMed. For each of the 500 species the authors provide its accepted Latin bionomial scientific name, authority, family synonyms and common names, along with a code that relates to the safety of the species relative to coffee."
