"Plant Intoxicants illustrates an enchanting universal use of psychoactive plants in the nineteenth century. Von Bibra brings to the subject a keen intellect, an engaging sense of humor, and a refreshing open-mindedness unusual for his, or any other time."

– The Reader's Review

"An excellent work covering a fascinating and sometimes controversial subject. Recommended."

– Critical Review

"An entertaining journey into von Bibra's 19th-century examination of the cultivation and use of stimulants, narcotics, and hallucinogens. Ethnobotanist Jonathan Ott, considered to be von Bibra's contemporary counterpart, complements the author's work with an extensive annotation."

– Napra Review

“...this book remains an important cultural artifact. Although the chemical and cultural understandings of the plant intoxicants he discusses have moved on, it still remains a valuable text to the drug historian and, moreover, it is a genre defining pharmacography.”
