What is this book about?
Primarily, this book details the author's extensive experience and theoretical reasoning for treating hay fever using three main methods: Rosin-weed (likely referring to preparations based on colophonium or rosin), Ichthyol (a mixture of mineral oils and sulfur compounds used topically), and Faradic electricity (electrical stimulation). The author presents step-by-step instructions, dosage recommendations, and case studies to support the efficacy of these treatments. Furthermore, it provides a historical overview of gout, contrasting old humoral theories with newer pathological understandings, and critically examines the then-controversial hypothesis of anaphylaxis, which proposed that hay fever and other allergies were reactions to 'antigens' and involved a specific type of hypersensitivity, a concept that was not universally accepted.
