The Treatment of Hay Fever by Rosin-Weed, Ichthyol and Faradic Electricity: With a Discussion of the Old Theory of Gout and the New Theory of Anaphylaxis

A fascinating artifact of early 20th-century medical thinking, this 1912 publication captures a moment when physicians still balanced folk remedies with emerging scientific frameworks. Laidlaw, a physician, offers an earnest survey of hay fever treatments ranging from rosin-weed (a plant remedy from his family tradition) to ichthyol (a tar-derived substance) and faradic electrical therapy. What elevates the text beyond mere historical curiosity is its attempt to synthesize older theories of gout with the revolutionary concept of anaphylaxis, then just a decade old. The book reveals how turn-of-the-century doctors understood allergies not as we do now, but as a puzzle requiring multiple diagnostic and therapeutic approaches. Laidlaw's insistence that hay fever be viewed within a spectrum of related conditions shows surprisingly modern thinking. For readers interested in medical history, the history of immunology, or the evolution of how we understand allergic disease, this text offers a vivid slice of early experimental medicine, complete with its confident hypotheses and quaintCertain remedies.
