This is a sharp Medicine, but it is a Physician for all diseases and miseries.
—Sir Walter Raleigh upon viewing the axe that was to behead him[1]

A panacea is a treatment or practice claimed to be capable of curing many or all diseases. The longer the list of diseases claimed to be treatable, the higher the chance that the "cure" is woo.

Woo convention[edit]

Supporters of panaceas often (though not always) claim that there is One True Cause of All Disease that the medical establishment doesn't want you to know about (or, at least, that it is too closed-minded to acknowledge), and that can be treated with their preferred therapy. So, for instance, some homeopaths will claim that this cause is miasms, which can be cured with homeopathic remedies; some will claim that it is humoral imbalance treatable with bloodletting and purging, among other things; some others will claim that dehydration is the true cause of all disease, and all illnesses can be cured simply by consuming large amounts of water; some claim that hyperventilation is the cause, which can be cured with breathing exercises; others claim that the real cause is really pH imbalance; and still others will claim that "toxins" are the cause, and can be removed with pills or chelation therapy. The mere existence of so many contradictory theories (and contradictory treatments to go along with them, as shown in the list below) is in itself enough to cast doubt on their veracity. After all, they can't all be right.

Persistence of the myth[edit]

Panaceas are so widespread in anecdote-based medicine mainly because of three factors: 1) the placebo effect, which occurs regardless of the specific treatment or disease, 2) the fact that many illnesses usually resolve without treatment, and that even diseases that rarely clear up on their own can, sometimes very suddenly, undergo spontaneous improvement, and 3) misdiagnosis, which may lead to a person treating a disease they don't have. These are some of the reasons why, as Steven Novella notes, "If you are basing your claims on anecdotal experience, then any treatment will seem to work for anything and everything."[2] This is also why so much alternative health advice is contradictory; in the area of diets, for instance, what foods you should and shouldn't eat vary wildly depending on who you ask: fruitarians claim only fruits are healthy; many vegans and vegetarians say meat will kill you, while others say you should eat lots of it; and some say agave is a healthy alternative to mainstream refined sugar, while others say it's full of fructose and unhealthy, among many other examples.

Historical examples[edit]

Some of the oldest known panaceas include bloodletting and trepanation, which were used, at first, to expel evil spirits from the body, and later to balance the humors.[3] Tobacco was thought to be a cure for over 65 diseases, including cancer.[4]

The word panacea is also used in an extended sense to refer to non-medical courses of action or ideologies that can fix everything that's wrong with a given situation.
