A few – just a few – medical professionals bring up the ethics of therapists actually prescribing placebos as an element of treatment.
Margaret Talbot proposes in the New York Times Magazine (1/09/2000):"The truth is that the placebo effect is huge — anywhere between 35 and 75 percent of patients benefit from taking a dummy pill in studies of new drugs — so huge, in fact, that it should probably be put to conscious use in clinical practice, even if we do not entirely understand how it works."
Others might balk at the suggestion, but there seems to be an ethical shadow-line, where a drug-focused therapy may overlap with the physician’s responsibility (duty?) to care for his or her patient as more than a machine, as a being of heart-mind."The placebo effect can occur," as the physician Herbert Spiegel once put it, "when conditions are optimal for hope, faith, trust and love." It might sound sentimental, but then sentiment, working hand in hand with science, can make medical practice so much more powerful. A world in which placebo — preferably in the form of deft encouragement, but sometimes in the form of a harmless pill — was tolerated, even embraced, would be a world in which doctors never forgot that medical practice consists not only of the technologies of diagnosis and treatment but also of the careful tending of a patient’s expectations and the unabashed willingness to comfort."
