Quackery



Quackery and the Law


In the United States all products marketed as drugs must be tested in order to guarantee their relative safety before being made available to the public. There is one exception to this law. Homeopathic 'remedies' can be marketed as drugs but are except from the same safety standards as other drugs.

This goes back to 1938 when a former homeopath-turned-Senator (Royal Copeland of New York) added a provision to the Federal Food, Drug, and Cosmetic Act that exempted homeopathy from the same oversight by the Food and Drug Administration (FDA) that other drugs receive. Homeopathic 'remedies' require no proof that they're safe or effective in order to be marketed and sold, unlike other drugs.

Herbal and other supplements are in a different boat. If an herb or supplement is marketed with the claim that it will cure a disease or illness, then it must be reviewed by the FDA before going to market. If there's no claim to a cure, then the FDA doesn't really make an issue of it (unless the product has been shown to cause harm). Of course, one way to get around this is to use customer testimonials. As long as the customers are giving testimonials, and they reflect the customers' honest beliefs about their experiences, then it's fair game, but that's an issue for another blog.

The point is that homeopathic 'remedies' can claim to cure disease and illness (unlike herbs and supplements), and they don't need to be tested to prove that they actually work.

Robert L. Park, in his book Voodoo Science, points out that the smoking-cessation chewing gum Nicorette had to be proven safe and effective through numerous clinical trials before it could be marketed. Whereas on the same shelf in the same store you might find another smoking-cessation gum called CigArrest. This product required no clinical trials to test its safety and effectiveness because the manufacturers claimed that the gum was homeopathic.(1).

Since homeopathic 'remedies' have no active ingredients, there would be nothing to test for in a clinical trial. But homeopaths can still claim that it's a cure. As Park points out, locating the active ingredients in homeopathic 'remedies' "would be like trying to prove that holy water has been blessed."(2).

Homeopathy Mixup in France


The equivalent of the FDA in France (the AFFSAPS) revealed startling news this past November about a mislabeling of homeopathic remedies. Here are two short exerpts:

"AFSSAPS has been informed by Laboratoires Boiron of an inversion of the labelling of two homeopathic medicaments, The bottles labelled 'mother tincture of Gingko biloba' contain mother tincture of Equisetum arvense and vice versa."

"AFSSAPS has said that this mix-up does not pose any particular risk . . ."

Why does this mixup pose no risk, you might ask? Unlike mislabeling real drugs, homeopathic remedies are nothing but water (read following blog for details).

Consider this bit from the exchange between Lord Broers and Ms. Kate Chatfield of the Society of Homeopaths in England from the minutes of evidence to the Select Committee on Science and Technology.

Lord Broers: I have a simple, technical question about homeopathy and drugs. Is it possible to distinguish between homeopathic drugs after they have been diluted? Is there any means of distinguishing one from the other?

Ms. Chatfield: Only by the label.

Well, there you have it. There's no way to distinguish them because (I'll say it again) they're nothing but water!

Thanks to
DC's Improbable Science for this gem.

Homeopathy: Bogus Medicine



Homeopathy, that most bogus of medical practices, is based on two basic principles:

1. Like cures like.

At first blush this might seem like something akin to a vaccination, where one receives a small dose of a virus (often a dead virus) to help prevent one from falling ill with the viral infection. But a vaccination works by triggering the immune response so that your body will fight against that viral infection when it's encountered in the environment.

Homeopathy is nothing like this. If you have a skin infection whose symptoms might vaguely resemble poison ivy, then ingesting a small dose of poison ivy would be the cure for you. Do you have seizures? Ingesting large quantities of plants from the nightshade family can also cause seizures. Therefore, the cure for you is to ingest small quantities of plants from the nightshade family.

2. The smallest effective dose.

According to homeopathy, you want to ingest a very diluted quantity of the "medicine." In fact, the more diluted the substance the better it is. Most homeopathic remedies are so diluted that not even one molecule of the active ingredient remains in the "medicine." It's nothing but water. But this is special water. This water somehow has a memory of the active ingredient, and it is this memory in the water that acts as a cure. That's right, the memory of the water. Or as a homeopath might describe it: An imprint of the substance has been retained in the water.

Is there any scientific evidence for such an imprint or memory in water? None. But that doesn't stop homeopaths. Science, they say, hasn't figured out how to identify or measure this imprint yet. Homeopaths don't require observational evidence of imprints or memories in water. They just know that these imprints exist. But how they know is anyone's guess.

This sounds like it was made up by some 18th century quack, before the rise of modern medicine. And in fact that's the case.
Samuel Hahnemann (1755-1843) came up with homeopathy. And while scientific medicine has improved over the years through research, studies and evidence, homeopathy hasn't changed one drop since the day of Hahnemann.

What's more disturbing is that homeopaths claim that their "cures" actually work. But every properly designed scientific test of homeopathy has shown that it works no better than a placebo. All experiments of homeopathy that show otherwise have been proven to use flawed methodologies in their experiments.

Save your time and money. Don't waste it on homeopathy. It's only water.
