“Let’s be clear,” says Edzard Ernst, emeritus professor of complementary medicine at Exeter University, “there are two types of detox: one is respectable and the other isn’t.” The respectable one, he says, is the medical treatment of people with life-threatening drug addictions. “The other is the word being hijacked by entrepreneurs, quacks and charlatans to sell a bogus treatment that allegedly detoxifies your body of toxins you’re supposed to have accumulated.”
If toxins did build up in a way your body couldn’t excrete, he says, you’d likely be dead or in need of serious medical intervention. “The healthy body has kidneys, a liver, skin, even lungs that are detoxifying as we speak,” he says. “There is no known way – certainly not through detox treatments – to make something that works perfectly well in a healthy body work better.”
Much of the sales patter revolves around “toxins”: poisonous substances that you ingest or inhale. But it’s not clear exactly what these toxins are. If they were named they could be measured before and after treatment to test effectiveness. Yet, much like floaters in your eye, try to focus on these toxins and they scamper from view. In 2009, a network of scientists assembled by the UK charity Sense about Science contacted the manufacturers of 15 products sold in pharmacies and supermarkets that claimed to detoxify. The products ranged from dietary supplements to smoothies and shampoos. When the scientists asked for evidence behind the claims, not one of the manufacturers could define what they meant by detoxification, let alone name the toxins.
