American medicinal barks

Alice Henkel's American medicinal barks is a concise yet authoritative contribution to early twentieth-century pharmacognosy, devoted to the identification, properties, and therapeutic uses of bark-bearing trees and shrubs employed in American medicine. Combining scientific precision with practical clarity, Henkel surveys botanical characteristics, commercial sources, and medicinal applications, situating each bark within the expanding framework of modern materia medica. The work reflects a period when botany, pharmacy, and commerce were closely intertwined, and its lucid descriptive style makes it valuable both as a technical manual and as a document of the history of medicinal plant study in the United States. Henkel, a botanist associated with the U.S. Department of Agriculture, wrote from within a scientific culture increasingly concerned with the accurate classification and standardization of plant-based drugs. Her professional engagement with economic botany and medicinal plants clearly shaped this book, which addresses the need for reliable botanical knowledge in pharmaceutical practice. The text bears the mark of a researcher attentive to both taxonomy and utility. This volume is especially recommended to historians of science, herbal medicine scholars, pharmacists, and readers interested in the intersection of botany and medical practice. Henkel's study remains an instructive and historically rich guide to a once-essential branch of American therapeutic knowledge.
