A report from the British Medical Journal states that more than half of internal medicine specialists report using a placebo treatment, and they believe this to be ethical.
What they do not realize is that the nutritional supplements that they offer and believe to be placebos really work. Most of these therapies have simply not been studied with appropriate clinical trials to prove their effectiveness. This is not a placebo effect but a real clinical effect that they are producing without their awareness. Either way, the treatment is often effective.
