The Pharmaceutical Formulary by J. Oldham Braithwaite, first published in 1899, is a comprehensive reference work that consolidates and compares the pharmacopoeias of Britain, France, Germany, and the United States, along with notable unofficial formularies. This 12th edition of Beasley’s Pocket Formulary serves as a vital resource for pharmacists, physicians, and students of medicine, offering detailed insights into the preparation and formulation of medicinal substances.​

The book meticulously catalogs over 450 pages of formulas, encompassing a wide array of medicinal preparations. These include tinctures, syrups, ointments, and powders, each accompanied by precise instructions for their preparation and dosage. The formulations are organized systematically, reflecting the standards and practices prevalent in the late 19th century, thereby providing a historical perspective on pharmaceutical practices.​

In addition to its practical applications, The Pharmaceutical Formulary offers valuable insights into the evolution of pharmaceutical science. By juxtaposing the pharmacopoeias of different nations, it highlights the variations and commonalities in medicinal formulations across cultures. This comparative approach not only enriches the reader’s understanding of pharmaceutical history but also underscores the global nature of medical knowledge and practice.​

Today, this work stands as a testament to the meticulousness and dedication of early pharmaceutical practitioners. While some of the formulations may have been superseded by modern advancements, the book remains an invaluable resource for those interested in the historical development of pharmacology and the foundational principles that continue to influence contemporary practices.
