Hypochondriasis: A Practical Treatise (1766)

Few ailments have plagued humanity as persistently as the terror of being ill. In this 1766 treatise, John Hill tackles what his contemporaries called 'the vapors' or 'the spleen' - a condition we now recognize as health anxiety, but which 18th-century physicians located squarely in the abdomen. Hill prescribes for a disorder of the imagination that causes real suffering:bloating, fatigue, palpitations, and the constant conviction of terminal disease. What makes this brief work endlessly fascinating is not its medical accuracy, but its window into an era before the mind-body split. Hill offers remedies that range from the sensible (exercise, diet) to the improbable (various tinctures and powders), all delivered in a brisk, moralizing prose style peculiar to the Georgian era. For readers curious about where our modern understanding of somatic symptom disorder came from, or anyone who has ever Googled symptoms at 2am, this little treatise offers a strange comfort:the anxious body is ancient, and we have always struggled to tell the difference between real illness and the fear of it.
