Many areas of interest will have passed through Agincourt as fads, phases, or outright tomfoolery. Medicine is surely one of them.
What’s accepted as medical treatment these days has been a contentious topic throughout history. The 19th century certainly saw more than its share of largely unregulated medical quality as well as quackery. Quite aside from the craze for patent medicines throughout the years leading to WWI, There were a dozen or more alternative medical treatments derided by the AMA and its predecessors. Bet you’ve never consulted a Naprapath. I seriously doubt you could find one in a metropolitan area under 100,000 population. The same may be true for Homeopathy. Chiropractic, on the other hand, is more likely found in your phonebook. [BTW, do phonebooks still exist? Asking for a friend.]
