Homeopathy by the (mind-boggling) numbers
GUEST POST BY MATT PARKER
I have just purchased a packet of Boots-brand 84 arnica homeopathic 30C Pills for £5.09, which Boots proudly claim is only 6.1p per pill. Their in-store advice tells me that arnica is good for treating “bruising and injuries”, which gives the impression that this is a very cost-effective health-care option.
Unlike most medication, it didn’t list the actual dose of the active ingredient that each pill contains, so I checked the British Homeopathic Association website. On their website it nonchalantly states that to make a homeopathic remedy, they start with the active ingredient and then proceed to dilute it to 1 per cent concentration. Then they dilute that new solution again, so there is now only 0.01 per cent of the original ingredients. For my 30C pills this diluting is repeated thirty times, which means that the arnica is one part in a million billion billion billion billion billion billion.
The arnica is diluted so much that there is only one molecule of it per 7 million billion billion billion billion pills.
It’s hard to comprehend numbers that large. If you were to buy that many pills from Boots, it would cost more than the gross domestic product of the UK. It’s more than the gross domestic product of the entire world. Since the dawn of civilisation. If every human being since the beginning of time had saved every last penny, denarius and sea-shell, we would still have not saved-up enough to purchase a single arnica molecule from Boots.
Then the process of consuming enough pills to get that one molecule also boggles the mind. You can try imagining Wembley Stadium completely filled with people, all drinking pints of medicine at the rate of two an hour. For just one of these people to eventually consume one molecule, you would need a million Wembley Stadiums all at full capacity with people who have drinking pints constantly since the Earth formed 4.5 billion years ago. Oh, and you’d need 737 million such Earths.
That’s only for one molecule. Molecules are tiny: it takes about a billion of them to cover a standard metric full-stop. To put homeopathy in a medicinal context, if you wanted to consume a normal 500mg paracetamol dose you would need ten million billion homeopathic pills. Where each pill is the same mass as the Milky Way galaxy. There is actually not enough matter in the entire known Universe to make the homeopathic equivalent of a single paracetamol pill.
So why are Boots putting their trusted name on pills that are labelled as a medicinal product, but contain nothing other than sugar? They’ve come out and said that there is no evidence to suggest that homeopathic remedies are efficacious but they will sell them if people believe they work.
Homeopathy is actually based on 18th century wishful thinking that water will somehow remember substances that it had previous contact with (but will forget the countless effluent that it has passed through). That a 10 billion year old water molecule will remember everything it has touched flies in the face of all known science and is an insult to any thinking person. Sincere people with medical needs buy homeopathic remedies only because they masquerade as being something more than mere sugar pills.
They are an insult to the herbal remedies on the shelf next to them at Boots; at least snake-oil has the decency to contain some snake.
