Homeopathy: Government-funded quackery

ducks in a row

There have been a couple of articles on the Canadian news site recently about homeopathy that have caught my eye recently.  One was about claims that homeopathy could prevent measles (referred to as homeoprophylaxis), and another was about the Canadian government funding an aid mission to Honduras involving a delegation of homeopaths claiming to cure Chagas disease and other infectious diseases.

There is plenty of pseudoscience in the world, and homeopathy is a prime example.  It may be promoted as a natural remedy, but I suspect most people aren’t aware of the true quackiness of it.  On the surface, it sounds like a natural, plant-based treatment kind of like the various herbal products filling the shelves at your average pharmacy.  Except it’s a whole lot weirder when you take a closer look at the ideas underpinning it.  I first heard about this when I was in pharmacy school back in the day, and I remember at the time thinking it had to be a joke.

Homeopathy is based on the idea that like cures like, so substances that produce certain symptoms in a healthy person would relieve those same symptoms in a sick person.  The founder of homeopathy, Samual Hahnemann, proposed that diseases are caused by “miasms”, and treating the symptoms rather than the underlying miasm would only make the condition worse.  He also proposed that a negative state of mind would attract these miasms.  Hello law of attraction!

Homeopathic remedies are created by repeatedly diluting the substance with water or alcohol, with the idea that the more it is diluted the more potent it is and the stronger the therapeutic effect it has.  That’s right, the more diluted, the greater the potency.  Except that it’s diluted so much that there are likely no longer any molecules of the original substance to be found in the remedy.  How does that work?

That’s where the memory of water comes in as a proposed explanation.  Say what?  With each dilution, the preparation is vigorously shaken (referred to as succussion), and this supposedly causes the water molecules to retain a memory of the substance.

Hahnemann used a C-scale is used to denote the number of dilutions.  He recommended 30C dilutions for most purposes, which works out to 1 part substance in 1060 parts of the solution.  In case you’re interested, that’s one molecule of the original substance to a novemdecillion molecules of diluent, or:


Certain homeopathic products have ended up being made at a dilution level that actually did result in molecules of the original substance being present, including poisonous substances like arsenic, causing serious adverse effects.  Oops!

The homeopathic measles prevention remedy mentioned in the CBC story uses nosodes, which come from products of a diseased human or animal, including pus, blood, feces, and other tissue.  According to the CBC, Health Canada has a lengthy list of nosodes that are authorized for use in Canada.  If I was interested in water with poop-memory then my toilet would do the job just fine.

I think when it comes to all things health-related, it is government’s job to protect people from their own unawareness (or stupidity).  “Remedies” that fly in the face of the fundamental principles of science do not belong in health care, particularly in government-funded foreign aid.

I’m not against natural products in general.  But pseudoscience sticks in my craw, and homeopathy is one of the wackier examples.  Anyone suggesting that this snake oil can be used to prevent serious infectious diseases could use some good head-shaking, perhaps with some poop-memory-water.  I believe governments need to be more proactive in regulating homeopathic products so that their labels clearly indicate their pseudoscientific basis.  If nothing else, products that have been shaken with pus, blood, and feces need to let people know what they’re signing up for.  Personally, I’m going to pass.

Note: Since I wrote this post the Canadian government has announced it’s cutting off funding to the organization sending homeopaths to Honduras.  It’s nice to see when governments decide to do the sensible thing.

  1. It’s scary when ‘quackery’ and quick fixes and magical remedies not based in scientific testing or proof are unregulated and promoted in such ways. As for nosodes, I hadn’t come across that term before but thinking of what that includes makes me queasy. I read an article just the other day about how Amazon is selling a book on some kind of homeopathic something-or-other for curing autism. Yikes. x

  2. Wow 😮 i use one homeopathic product (Bach Rescue Remedy) in addition to therapy, exercise, Prozac and trazodone. The homeopathic alone wouldn’t manage my anxiety and the thought that more diluted is stronger is DUMB! Woo woo! Great post

  3. I have heard some amazing stories of homeopathic “healings”, but not sure about much of it myself. I think I have used homeopathic ear drops in the past that did help, but I think that is the only thing like that I’ve really tried.

      1. Possibly a placebo affect for many. If it doesn’t hurt them and the get a positive affect from it, I guess it could be worse. Although using it in place of vaccines is worrying.

  4. Wow, all I can say is, “Quack, quack! Quack, quack!”

    Great blog post!! It was totally new material for me, and I loved the attitude with which you presented it! (“Quackery” has got to be one of the funniest words around!)

    Huh, yeah. I always thought homeopathy simply involved taking, like, supplements or vitamins. And I’m a fan of supplements. But this was mindblowing!! Wow, it’s hard to believe anyone could believe in this!!

      1. I was just now talking to my dad and I said, “Quakery: it’s where they make the Quaker Oats.” Can you believe he didn’t believe me?!?!

  5. I couldn’t agree more! I think people romanticize nature too much–looking to it to solve all of our problems. Yet, are problems are always natural–biological decay, death, disease, natural disasters…etc.

    Anyway, thanks for the post!


  6. This is an eye-opener that such quacks would even go as far with this as they have. Their just opening a whole huge can of worms on an existing problem.
    I know in no way this relates, but it does remind me of all the ridiculous dietary crap that is out on in the market.
    You bring so much light to subject matters that a great number of people ignore.
    This was a truly insightful post, Ashley. Great job! 😊

  7. I want to try CBD oil maybe for my anxiety. I don’t know if that also counts of natural products. I also use sometimes bach rescue and some things may help but I agree that medicine are important.
