Because it opens up a lot of very important medical ethics problems. During trials, the doctor and the patient don't know that the patient is getting a placebo (it's called "double blind"). If people know that what they are getting is a placebo, I don't think it works as well. So the only way to get an effective placebo is to lie to the patient and tell them it's a good drug. But there is a long history of abuses in medicine (Nuremburg, Tuskegee syphilis experiment, etc.), so "informed consent" is very very very important in medical ethics. This means you can't lie to patients. To use placebos as you suggest, you'd have to throw that out. This is a dangerous path.

"Can the recommendation for a treatment intended to promote the placebo effect be made without deception and also without undermining its therapeutic potential? Consider, for example, the case of a clinician who recommends treatment with acupuncture for a patient with chronic low back pain who has not been helped by standard medical therapy. Aware of the results of the recent acupuncture trials, described above, this clinician thinks that acupuncture may work by promoting a placebo response. The clinician might provide the following disclosure to the patient: “I recommend that you try acupuncture. Several large studies have shown that traditional acupuncture is not better than a fake acupuncture treatment, but that both of these produce considerably greater symptom improvement in patients with chronic low back pain condition as compared with those patients who receive no treatment or conventional medical therapy. Although the specific type of needling doesn't appear to make any difference, it is likely that acupuncture works by a psychological mechanism that promotes self-healing, known as the placebo effect.” On its face, this disclosure appears honest. A patient who received this disclosure and subsequently got better after undergoing acupuncture might nonetheless develop a false belief about why it worked. This does not mean, however, that the patient has been deceived by his physician." from: Placebo Effects: Biological, Clinical and Ethical Advances (Damien G Finniss, Ted J Kaptchuk, Franklin Miller, and Fabrizio Benedetti PMCID: PMC2832199 / NIHMSID: NIHMS169379 http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2832199/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2832199/

  But does the placebo effect work as well if the patient is told that type of words?
