The Chronic Diseases: Their Peculiar Nature and Their Homoeopathic Cure (Set of 2 Volumes)

By Samuel Hahnemann

Hahnemann's second great book, written in his seventies, arguing that stubborn long-term illness is driven by underlying "miasms" rather than passing complaints. The two volumes pair his theory of chronic disease with the enormous antipsoric materia medica he assembled to treat it. It remains the foundation text for how classical homeopaths think about deep-seated, relapsing conditions.
