For over half a century, one name has stood as the gold standard in the study of medicines derived from natural sources: Trease and Evans. First published in 1961 by George Edward Trease, the textbook has evolved through multiple editions, with William Charles Evans taking the helm to refine and expand its scope. Today, the Trease and Evans Pharmacognosy 15th Edition represents the most comprehensive, up-to-date, and authoritative resource in the field of pharmacognosy—the study of medicinal products derived from plants, animals, and microorganisms.
