Homeopathy is a 200-year-old medical philosophy that has been thoroughly debunked. It survives today thanks only to wishful thinking, ignorance, marketing, and because it is too useless to be all that dangerous.1 Unless it’s being sold by corrupt profiteers with no regulation and product contamination is common, contributing substantially to a 50% rise in supplement-related calls to poison centers from 2005 to 2012.2 That would be dangerous.
It is the flagship in the alternative medicine fleet: the most profitable, absurd, and snakey of all the major snake oils. Selling homeopathic remedies is unethical, and buying it is foolish. It’s legitimacy is on par with faith healing and psychic surgery.
This is not a detailed and referenced review of homeopathy — there are plenty of other pages for that. This page exists to emphasize one key point, what I believe is the most important thing people need know …
Homeopathy is much more bizarre than most people realize
Most people have no idea just how strange homeopathy is. They accept it — or don’t reject it — because they assume it’s herbal medicine.
The deal-breaker for many consumers, if they know about it, is that homeopathy is not an “herbal” or “natural” remedy, but a “magical” one that “has the scientific plausibility of using Harry Potter’s wand to treat illness” (Caulfield). It’s based on a principle that reeks of flaky physics and old-timey snake oil flamboyance: the idea that a substance can convert water into a kind of medicine through a process of exotically extreme dilution. Most homeopathic remedies have literally no active ingredient, or in such low concentrations that you could drink a swimming pool of it and only get a few molecules.
And then there’s the ingredients they choose to dilute. Most are deliberately counter-intuitive: you use something that, in normal concentrations, would cause the symptoms you want to treat. Many examples don’t make any sense in those terms, and many more are completely fantastical: homeopathic volcano? Dinosaur? And bubonic plague, black hole, plutonium, and so on. I’m not joking. The things homeopaths have supposedly turned into medicines is truly stranger than fiction, and their explanations are as pseudoscientific as it gets.3
None of it works, of course,45 and the principles of homeopathy are completely at odds with centuries of chemistry and physics. Some people, of course, are quite happy with vague references to quantum physics to explain alternative medicine, but you really have to be a card-carrying new age sort to go there. For most people, that crosses a line — it’s just too far out in left field.
But they have to find out first! And many people never do.
Fortunately, doctors, scientists and skeptics are unanimously and harshly critical of homeopathy, and have published many good quality critical reviews. For instance, see my own article about homeopathic arnica — the most popular of all homeopathic products, intended to treat inflammatory pain.

The FTC finally goes after homeopathy
In November 2016, the American Federal Trade Commission issued a statement promising to (finally) hold homeopathy products to the same efficacy and safety standards as other products.6 For historical and political reasons, the FTC has always failed to protect consumers in this way, and the policy change is welcome but long overdue.
“I love to see a regulatory agency actually do its job,” writes Dr. Steven Novella, a prominent critic of homeopathy. “In essence, the net effect of the labeling on the product cannot be misleading to the consumer. I think this is giving some wiggle room for homeopathic manufacturers to try their best to mislead their potential customers, but this is probably the best the FTC can do within its mandate. The new FTC policy only really works if the public has a basic level of scientific literacy. That is a much longer struggle.”

- “NHMRC Statement: Statement on Homeopathy,” an article in NHMRC.gov.au, 2015. An exhaustive review of homeopathy was conducted by the Australian government in 2015, concluding that “there are no health conditions for which there is reliable evidence that homeopathy is effective.” Several related documents go into much greater detail, especially: NHMRC Information Paper: Evidence on the effectiveness of homeopathy for treating health conditions (PDF, 392KB).
- Science-Based Medicine publishes a good collection of critical articles and resources about homeopathy. A great place to start is Dr. Steven Novella’s commentary on the FTC’s historic decision to finally crack down on homeopathy products.
- Homeowatch is entirely devoted to debunking homeopathy.
- Wikipedia has a thorough article about homeopathy. It’s not neutral — homeopaths probably dislike it. Still, it seems well-written and it’s heavily referenced, and you can’t beat that as a starting point. It provides a lot of well-sourced information.
- The National Center for Complementary and Alternative Medicine is a curious case: an organization that has a mandate and huge budget to prove that homeopathy works, but hasn’t been able to do it. Their information page on homeopathy reads with a friendly-to-homeopathy tone, as though it’s a rather good idea … but openly acknowledges that there is still no evidence that it works (previously quoted), even after many years of well-funded attempts to prove it.
- The National Center For Homeopathy disagrees with NCCAM, and claims that “there are literally hundreds of high quality, published basic science, pre-clinical and clinical studies showing that homeopathy works.” They publish a bibliography and a few articles. There are numerous other homeopathy associations with similar websites.

There’s a classic typical example: the Werner video, in which a daft homeopath earnestly makes a case for homeopathy on the basis of a string of appalling misunderstandings of physics. If you know nothing about physics, trust me … neither does she. Dr. Steven Novella writes:
Werner may be more clumsy and fumbling than more eloquent homeopathy proponents, but when you strip it down, magical vibrations is what you get. But Werner does a fabulous job of exposing the gaping holes is homeopathic nonsense.

Most analyses of the research on homeopathy have concluded that there is little evidence to support homeopathy as an effective treatment for any specific condition.

This review attempted to look at the studies that are available about the efficacy of homeopathic remedies.
Seventeen articles were studied and assessed.
Looking at all of these articles, “there was no condition which responds convincingly better to homeopathic treatment than to placebo or other control interventions. Similarly, there was no homeopathic remedy that was demonstrated to yield clinical effects that are convincingly different from placebo.“
The author concluded: “The best clinical evidence for homeopathy available to date does not warrant positive recommendations for its use in clinical practice.”BACK TO TEXT
