“This Mechanism Is Not Well Understood” – Lacunae in Science

Medline, that key repository of all things biomedical, holds more than 20 million citations.  Of those, over 1 in 200 state variations on one of my favourite sentences in science: today’s title theme (not well, not clearly, not yet, not currently…) – biomedical mechanisms defying science.  Searching Google at  ‘advanced reading level’ (aka ‘so not Yahoo Answers’) , the relevant terms turn up in 29% of indexed pages pertaining to health or science or medicine:  a rough measure to help along a general ‘I wonder’ about the Unknown in science and medicine.

The ‘mechanism’ in many CAM therapies – notably in homeopathy – ‘is not well understood’.  Skeptics have been trying to transmute this – by media drip feed –  into ‘there is no mechanism’.  Or, as then-US-Defence-Secretary Rumsfeld explained to justify a war: stick with what we can see – ignore the ‘unknown unknowns’.

But even if all placebo-only allegations in relation to complementary therapies held true, would not this too mean homeopathy and other CAM must be ‘better understood’? Placebo is a frontrunner among the mechanisms in healthcare which are barely understood.  So where are the skeptic researchers investigating possible placebo aspects in CAM? Assumption, assertion and strange mud-slinging is all we get.

The louder skeptics in the UK have elevated themselves to a new science police, notably in the current ASA campaign that prompted this blog: persecuting individual practitioners, not large companies.  The ‘multi-million pound industries’ in CAM often cited by skeptic groups consist almost entirely of over the counter sales of vaguely alternative health supplements. Guess who owns Seven Seas, the biggest supplier in this market?  German pharma giant Merck.  Now there’s a really big target…  Yet the one-person CAM practices in little clinics up and down the country are what the right-thinking skeptic aims at.  Advice from the Woo-finder General to his hench-writers: pick anything on your chosen target websites – the ASA is duty-bound to investigate, and your complaint might just stick even if spurious.

One key argument between ‘science’ and ‘homeopathy’ (an arbitrary polarisation much fostered by skeptics) hinges around plausibility.  On whose authority?   Why would someone who readily accepts the wilder reaches of quantum concepts and the possibility of multi-verses, who expects that material proof of the Higgs boson is just around the corner, and doesn’t discount the graviton, insist so strongly that this one modality is simply impossible?  None but the most egg-headed of boffins have even a small proportion of the science pieces they need to puzzle together for themselves what makes sense in the big picture and what doesn’t.  Everyone else… takes it on trust.

Here’s Brian Cox quoting a contemporary of Hahnemann’s , Humphry Davy – a ‘personal hero’ no less.  So let’s hear it for Samuel Hahnemann, pioneering thinker and embattled scientist, Professor Cox.  But no, he’s gone to the Dark Side: Brian Cox is proud patron of and speaker for those indiscriminate CAM-busters, the ‘Skeptics in the Pub’ movement – that’s the people who hire strategists to enthuse and instruct their acolytes in the art of malicious mass campaigning, the groups who teach debating techniques the better to hammer opponents with spurious ‘logical fallacy’ attacks, in short, the would-be freethinkers whose sole aim is to score points against what they present as rip-off pseudoscience (rolling everything from UFO conspirators to integrated medicine on the NHS into one tidy package).

"Fweee Bwian!"

But still we trust in Brian.  And Ben.  And Simon.  Even that dodgy Edzard with his movie baddie accent.  In spite of clear evidence of bias.  Trust – what a wonderful thing.  Safety, certainty.  If I trust that you tell me the truth, then I need look no further: a lot less hard work.  So if you adopt ‘the facts’ pre-digested from the Messrs Cox and Dawkins (sorry – Professors, to give them their correct, authority-bestowing titles), taking it in good faith that they have worked out the difficult bits you don’t quite get, then life is so much easier.  But isn’t that … just faith?  It certainly isn’t scepticism.

Meanwhile, lacunae of unknowing in the current information base of science and of medicine remain, the voids filled at need with apparently tidy cover stories. Like ‘it’s just placebo’.  Just?  Some things scientists know (and admit) they don’t know.  It’s the ‘unknown unknowns’ they struggle with but – unlike the benighted Rumsfeld – anyone, not just scientists, can embrace and face that completely open uncertainty… that’s how the ‘c’ gets back into scepticism.

To Infinity and Beyond

What is a homeopathic remedy?  A sugar pill? ‘Just water’?  Homeopathy was named by one Dr. Samuel Hahnemann.  First-rate scientist, rubbish PR person.  Homeo-pathy?  Awkward man – awkward word: difficult to spell, easy to lampoon.  Even easier to misrepresent.

My favourite skeptic skit… completely misleading, but – anything for a laugh, eh?

Laughs aside, homeopathy – a remarkably cheap, effective, low-tech health care option, affordable even to the poorest nations – deserves proper research funding.  Key elements of treatment:

  • Symptom similarity  –  determined through tests on the healthy (pathogenic trial, proving)
  • Individualisation – symptom similarity is as individual as people
  • Serial dilution/agitation –  developed to minimise drugs toxicity/side effects

‘Homeopathy’ is not a protected term; mis-use of the word commonly confuses public perception.  Here is someone else who seems confused about homeopathy:

Very likely this man knows quite well that his seaside dropper stunt is misleading nonsense.  Ah – isn’t that… yes, skeptics call homeopathy ‘misleading nonsense’ while spreading misleading nonsense about this widely used and accepted healing modality.

Dilution to the infinitesimal  is not what makes a medicine ‘homeopathic’.  Ultra-high diluting was Hahnemann’s answer to drug-induced pathogenic (‘side’) effects.  He employed serial dilution, a method still commonly used in pharmaceutical labs.  He just took it an inexplicable, observation-based step further.

Confirmed similarity to symptoms of disease makes a substance homeo-pathic – similar to the individual’s suffering.  Fact is, most ordinary medication too works because a given substance can cause in the healthy just those symptoms it is designed to treat –  medicinal substances have naturally both anti- and homeo-pathic effects.  This is most easily seen in the so-called ‘paradoxical effect’ – e.g. analgesics inducing pain.  The use of Zolpidem*, an insomnia treatment, to rouse coma/PVS patients is one example of the homeopathic similarity principle in ‘off label’ drug use.

The simillimum aspect of ordinary medicines is easiest to spot in herbal remedies, for example chamomile (e.g. induces nausea if over-used = soothes stomach in normal use) or arnica (over-use a.o. causes microhaemorrhages = effective treatment for bruising).  Such similarity is a key factor in much primary drug action – which means a large chunk of medicine is in fact crudely homeopathic.

Conversely, if someone dishes out potentized remedies bought from a homeopathic pharmacy, this does not equate to homeopathicity: no similarity, no treatment, no effect.  That’s one reason why the ‘homeopathic suicides’ stunts are so risible: “Look, look I’m not dead – ha ha ha!”  “Yes, we know, dear… isn’t that nice?  We’d hate to see you damaged by your own stupidity.”

this man does not understand homeopathy - skeptic campaigner 'suicide' stunt

The beauty of potentized ultra-high dilutions is just that:  they can induce amazing health changes if properly prescribed  –  yet pass through harmlessly if ‘dissimilar’, that is, not needed or not properly individualised to a patient.

Hahnemann prescribed standard doses of  his newly discovered ‘similars’, successfully, for several years.  In his quest for minimising side effects, why would an ambitious young doctor still building a reputation scupper his chances? Why refine this peculiar dynamization process unless it worked well?  Were both he and his patients the first gullible victims of homeoathy – just like the 500 million worldwide who use it today?  All of us? Just fools?  Really?

Some medics were disparaging homeopathy on the grounds of implausibility decades before the science community accepted Avogadro’s Constant.  What today’s skeptics believe about homeopathy is worn-out old tricorn jazzed up with the high-tech feathers of molecular biochemistry.

Edzard Ernst demonstrates the double blind method

In Europe, much homeopathy (and a related application, ‘homotoxicology’) is practiced using low 1:10 serial dilutions.  Definite material doses are still present in such preparations. In dismissing these as much as high potencies, professional CAM ‘debunker’ Edzard Ernst and friends gloss over the pharmacologically quantifiable content.   I’d agree that the degree of homeopathic dilution really is just a question of … degree.  So, naturally, 1:10 dynamisations, like infinitesimal ultra-high preparations, do work. Being materially small doses, they act less subtly, treatment indications are more limited: a half-way-house between the holistic, individualised applications of the ultra-high level and the single-track biochemical usage of modern medicine.

Ultra-high dilutions are not easy to understand.  There is no known mechanism that shows definitely why they work; there is much new-agey mis-information.  Some people are attracted to homeopathy because it all seems so miraculous.  Others get angry at the inexplicable.

Science has a long history of revolutionary discoveries that overthrow old world orders, from Copernicus to Einstein and beyond. The unknown is unknowable – until it is discovered.   I can see the action – and results – of the infinitesimal in my practice every day.  Whether or not a biochemical, quantum or other explanation for homeopathic medicine will be discovered eventually… it really doesn’t matter to the people who get better.

*Incidentally, Zolpidem is an example of the evidence-mindedness of medical care: although studies have to date failed to confirm the early promise of this application for the drug, many if not most PVS patients are given Zolpidem on an experimental basis.  And why not?  It’s just that if one went strictly by the demands of EBM, doctors would not agree such off-label use until confirmed in large-scale trials.
