"Gehe's Arzneipflanzenkarten" presents a comprehensive visual and scientific overview of medicinal plants based on original photographic documentation by Josef Ostermaier. This collected book edition brings together the complete series of 120 cards, offering detailed representations of plants used in pharmacy and traditional medicine. Designed for pharmacists, students and professionals, the work combines visual accuracy with practical botanical and pharmacological information. The volume compiles the complete set of twenty series of medicinal plant cards originally issued separately, now bound as a coherent reference work. Each plant is documented through high-quality photographic plates accompanied by descriptive texts outlining botanical characteristics, habitat, active substances and medicinal applications. The structure follows a systematic botanical approach, allowing identification and comparison between species. The work reflects early twentieth-century pharmaceutical education practices, where visual material played a crucial role in training pharmacists and herbal specialists. The combination of photography and scientific annotation makes the book both an educational tool and a historical document of applied botany and pharmacognosy.
