A study of differently packaged aspirin tablets, for example, found that those that were branded to look more expensive worked much better than those that looked plain and generic.<\/p>\n<p>In other words, paying ten times more for branded painkillers than for generic ones actually seems to enhance their effect. There\u2019s nothing chemical going on. It\u2019s the same drugs. It\u2019s our perception of them that\u2019s going on. We perceive something that\u2019s more expensive as being better. Ultimately, it\u2019s our own perception that enhances the painkilling effect. In this case, our brain produces its own natural (endogenous) painkillers.<\/p>\n<p>Generally speaking, looking at stats for placebos, they work better for pain in the US if they\u2019re injected, yet they work better if they\u2019re tablets in the UK. It\u2019s our perception that matters. People in the US have more faith in \u2018getting a shot\u2019. People in the UK have more faith in \u2018popping pills\u2019.<\/p>\n<p>Studies of anti-ulcer treatments in different countries reveal a similar kind of effect. A trial of Tagamet in France found it to be 76% effective with the placebo coming in at 59%. Yet a trial in Brazil found Tagamet to be 60% effective. In other words, a placebo in France was almost as good as the actual drug in Brazil!<\/p>\n<p>What we believe matters. Having faith in a particular doctor is likely to mean that her or his prescriptions will work better for you.<\/p>\n<p>In a British Medical Journal paper a few years ago, doctors who gave a \u2018positive consultation\u2019 (for minor ailments), where they reassured the patients that they would be better in a few days, were compared with doctors who gave what were defined as \u2018negative\u2019 consultations for the same kinds of ailments, where the doctors were less reassuring. Two weeks later, 64% of those who had a positive consultation were symptom free, yet only 39% of those who had a negative consultation were symptom free. Over and above the effect of an actual medicine prescribed, and your beliefs about it, is your thoughts, feelings, and beliefs about the doctor.<\/p>\n<p>Did she\/he listen to me? Did she\/he show me empathy? Was she\/he confident and reassuring? Or even, was she\/he old even enough to understand my case properly? And she\/he did look and sound very intelligent!<\/p>\n<p>These are all conversations we have with ourselves during and after a consultation. The thing is, the dominant thoughts and feelings that we settle on matter.<\/p>\n<p>And it would be wrong to think that any benefit of how we think, feel and believe is \u2018just psychosomatic\u2019. The contents of our minds shift our biochemistry. Placebo research suggests that our brains very often produce the chemistry that is required to deliver a result we\u2019re expecting to happen.<\/p>\n<p>What does this overall kind of effect above say about our own minds? It shows us that what we think about, how we feel, and what we believe, matters. It\u2019s not a reason to ditch our medicines, of course. Taking and acting on medical advice is sensible. But it shows that our own thoughts, feelings and beliefs <em>about\u00a0<\/em>the medicines and <em>about\u00a0<\/em>doctors play an important role in recovery and healing.<\/p>\n<p>Taking it a little further, I would even extend it and say that, for some people, their thoughts, feelings and beliefs about the medical systems, insurance companies, and even pharmaceutical companies also matters.<\/p>\n<p>The latter point is something I\u2019m quite familiar with. I\u2019m a trained organic chemist and worked as a scientist in the pharmaceutical industry several years ago. I often hear people say that they mistrust the industry in general. As such, some think of the drugs they are prescribed with suspicion; some imagine that they are poisons, or that they\u2019re only being prescribed them so that the system can make a profit.<\/p>\n<p>All I can say is that most of the people I worked with in the pharmaceutical industry wanted to save lives. If you are prescribed medicine, rather than imagining it as something poisonous, imagine it instead doing the job it\u2019s supposed to do. Picture it as an animated character swimming through the bloodstream to where it needs to go and doing what it needs to do. If you\u2019re prescribed medicine, this is a much better use of your mind.<\/p>\n<p>So it seems that some drugs do work better if we believe in them, or if we believe in the doctor who prescribed them.<\/p>\n<p>The deciding factor, it seems, is what you believe!<\/p>\n<p><strong>References<\/strong><\/p>\n<p>For the study on branded vs generic aspirin tablets, see: A.
