The National Institute for Health and Clinical Excellence (NICE) is an independent UK organization that provides advice on which treatments and medical practices are likely to promote health. In other words, they comment on what they think is or should be the standard of care. This is a very important function, and the NICE is generally taken seriously.

That is why it was very disturbing to find that in their latest guidelines for low back pain they include recommendations for both spinal manipulation (wihout explicity naming chiropractic) and acupuncture.

The spinal manipulation recommendation is at least semi-reasonable, in that there is some evidence for modest benefit for spinal manipulation for acute uncomplicated low back pain. However there are still problems that derive from the bait and switch tactic employed by many practitioners of spinal manipulation.

On a recent episode of Fringe (a rather mediocre, in my opinion, series on the supernatural), the investigators come across apparent cases of spontaneous human combustion (SHC).  Popular Mechanics decided to write an article about the science behind SHC (it turns out there isn’t any) and luckily contacted me to give them the skinny. You can read the article here.

SHC is a fun pseudoscience in that there is nothing concrete at stake – no health claims, no products, no concerns about squandering limited research funds. It’s purely a scientific question, one highly amenable to skeptical analysis.

In order to understand SHC imagine the following scene: An elderly woman who lives alone is found dead in her apartment. She is the victim of fire; her body is mostly reduced to ash, and only the ends of her arms and legs remain. The ashen outline of her head lies upon the hearth of her fireplace, the iron grill of which has been knocked to the side. There are signs that a fire recently was burning in the fireplace. A brown greasy substance coats the walls and ceiling near the body, but otherwise the room is unharmed.

Now set aside all common sense and reason, and you’ll have a typical case of spontaneous human combustion.

If I tried to invent a product name that evoked the sense of patent-medicine snake oil from the 19th century I don’t think I could have done a better job. Duchy Originals detox tincture is just one more of thousands of snake oil products being marketed to the public with dubious health claims. Except this one is backed by the Prince of Wales.

The con is an old one – virtually random ingredients are put into a pill, elixir, tincture, or salve and sold with incredible hype but no science. So-called snake oil marketers have a long tradition of knowing their marks and the market. Claims are designed to appeal to the broadest market, to have maximal allure, and to be just vague enough to evade any pesky regulations that may be in effect. Claims also tend to follow recent fads, using the buzz-words that are hot, and often try to wrap cutting-edge sciency terms in the cloak of ancient wisdom.

Oh, and celebrity or pseudoauthoritarian endorsements help, too.
