The American Journal of Pharmacy, Volume 73, published in 1901 by the Philadelphia College of Pharmacy, is a significant historical resource that offers a comprehensive look into the pharmaceutical practices and scientific advancements of the early 20th century. This volume is part of a series that documents the evolving field of pharmacy, providing insights into the methodologies, discoveries, and challenges faced by pharmacists and researchers of that era.

One of the notable features of Volume 73 is its detailed examination of the active principle of the suprarenal glands, leading to the isolation of adrenalin. This groundbreaking research marked a pivotal moment in pharmacology, as it was the first time the active principle of these glands was isolated on a commercial scale. The journal delves into the physiological properties, pharmacological effects, and therapeutic applications of adrenalin, highlighting its significance in medical science. This study not only advanced the understanding of glandular functions but also paved the way for future research into other glandular substances.

In addition to the adrenalin study, the journal includes a monograph on the history, pharmacognosy, and chemistry of Cascara Sagrada. This comprehensive review provides valuable information on the origins, medicinal properties, and chemical composition of this plant, which was widely used for its laxative effects. The inclusion of such monographs reflects the journal’s commitment to documenting and disseminating knowledge about various medicinal plants, contributing to the broader understanding of herbal medicine during that period.

Volume 73 also features an in-depth analysis of the role of calcium oxalate crystals in the study of plant drugs. The research presented demonstrates how the presence and distribution of these crystals can offer insights into the identification and quality of various plant products. This study underscores the importance of microscopic and chemical analyses in ensuring the authenticity and efficacy of herbal medications, a practice that continues to be relevant in modern pharmacognosy.

The American Journal of Pharmacy, Volume 73, serves as a valuable historical document that captures the scientific rigor and curiosity of early pharmaceutical research. Its detailed studies and analyses provide a window into the practices and advancements of the time, offering contemporary readers a deeper appreciation for the foundations upon which modern pharmacy is built.
