Science Frontiers ONLINE No. 38: Mar-Apr 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Subtle Placebo A most interesting series of placebo experiments have been carried out by J.D . Levine and N.C . Gordon, of the University of California at San Francisco. The subjects were all dental patients who were tested when their surgical anesthesia was wearing off. The substances administered were: (1 ) a placebo; (2 ) morphine; and (3 ) naloxone, a substance that blocks the opiates produced in the brain. The doses were administered: (1 ) openly, when the experimenter knew which substance was being given; (2 ) by a person hidden from both experimenter and patient; and (3 ) by a machine. Two findings are particularly revealing. First, pain always increased after naloxone was administered, implying that the opiates blocked by naloxone are probably the same as those released by placebos. More significant, however, was the fact that both the open and hidden administrations of the placebo reduced pain while the machine-applied placebo resulted in more pain. In other words, when either the experimenter or the hidden administrator knew that the placebo was being given, the placebo worked. Levine and Gordon supposed that there must have been subtle clues, detected subconsciously by the patients, that the hidden person was administering the placebo. (Anonymous; "The Subtle Strength of Placebos," Science News, 127:25, 1985.) Comment. If no subtle clues existed, ...

Science Frontiers ONLINE No. 128: MAR-APR 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Fake Needles but Real Knives The effect of a patient's mind in medical procedures can be as powerful as drugs and real surgery. This is the well known placebo effect. But how can doctors differentiate between the healing power of the mind and that of chemicals and scalpels? The logical thing to do is to fake the procedure with one group of patients and compare results with a second group that got the "real thing." Of course, ethical problems come to the fore because doctors are supposed to cure people and not to pretend to. The ethical dimension is accentuated when real knives are employed and real blood flows. Our first item is not invasive but interesting nonetheless. Placebo acupuncture. Many physicians scoff at acupuncture. Placebo experiments could prove its efficacy. To this end, special placebo needles have been invented. Like the fake daggers used on the stage, the points are blunt and retractable. The acupuncture patient feels a pinprick and thinks he or she sees the needle penetrating the skin, but it's all fakery. At the University of Heidelberg, 52 people with rotator cuff tendinitis were split into two groups; 25 were punctured with real needles, the rest just thought they were. In this experiment, the first group showed much greater improvement than those treated with the fake needles. Real acupuncture was more powerful than the placebo effect. Now if we can only figure out how real acupuncture works! ...

Science Frontiers ONLINE No. 1: September 1977 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Addiction To Placebos A 38-year-old married schizophrenic was in psychotherapy for severe depression and multiple suicide attempts. She was addicted to methylphenidate, taking 25 to 35 10-mg pills per day. She was incredibly adept at persuading pharmacists to refill old prescriptions. With the help of her husband and a drug company, placebos were gradually substituted for the real pills to the point where only two real pills and 25-30 placebos were taken each day. The patient never noticed, indicating that the placebos satisfied the patient's real need-- something to fill an inner void. (Muntz, Ira; "A Note on the Addictive Personality: Addiction to Placebos."

... Science Frontiers ONLINE No. 16: Summer 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Belief Systems And Health Can one's mind-set affect one's immunity to disease? Lenard explores (in popular style) the roles of mental attitude, visualization techniques, and placebos in fighting and preventing cancer and other ailments. Placebos are nothing new. Most doctors admit they sometimes work for some people. Why, they don't know. Placebo action seems closely allied to a person's mental attitude. Many doctors will also allow that a positive attitude helps a lot in fighting illness and that depression aggravates it. Visualization techniques, though, are hotly debated. Will cancer cells be destroyed, or at least stop growing, if the patient visualized them as weak things that are vulnerable to the body's killer cells? Proponents of visualization recom-mend that a cancer patient visualize his killer cells as protecting knights in armor that swoop down and skewer the enemy cancer cells. In a visualization session, one focuses one's mind on such images and, in essence, wills his body to fight back. There is some evidence that visualization helps. (Lenard, Lane; "Visions That Vanquish Cancer," Science Digest, 89:59, March 1981.) Comment. The crucial scientific question in all the above methods is: How does a belief system mobilize biological systems? From Science Frontiers #16, Summer 1981 . 1981-2000 William R. Corliss ...

Science Frontiers ONLINE No. 22: Jul-Aug 1982 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Conditioned responses that short-circuit the conscious brain Don't let the title of this item deter you; this is serious stuff. We all know about the placebo effect. A sick patient improves because he believes he is getting a helpful medicine, even though it is an inert substance. The reverse works, too, at least in experiments with mice. It seems that mice can be conditioned into believing that an ordinarily delectable substance (saccharin and water) gives them stomach pain, by simultaneously injecting them with a pain-producing chemical. Unexpectedly, this chemical also suppressed the immune system of the mice. The mice, of course, knew nothing about the effect on their immune system. Nevertheless, whenever they received saccharin after being conditioned, their immune system was suppressed even though the pain-producing chemical was not administered. While one can imagine the mice consciously associating saccharin and stomach pain, and their brains somehow sending signals that simulated pain, it seems inconceivable that the mice knew anything about their immune system. We have always assumed that the placebo effect (and its reverse) worked because of the subjects' logical association of cause and effect, but evidently there is something else going on here! (Wingerson, Lois; "Training the Mind To Heal," Discover, 3:80, May 1982.) Comment. This all opens a rather large Pandora's Box, because it implies that ...

Science Frontiers ONLINE No. 72: Nov-Dec 1990 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Hypnotic Suggestion Superior To Salicylic Acid Forget the stump water, too, for hypnosis is better than both when it comes to chasing away warts. If you don't believe this, read the following Abstract. "Subjects with warts on their hands and/or feet were randomly assigned to a hypnotic suggestion, topical salicylic acid, placebo, or no treatment control condition. Subjects in the three treated groups developed equivalent expectations of treatment success. Nevertheless, at the sixweek follow-up interval only the hypnotic subjects had lost significantly more warts than the no treatment controls." (Spanos, Nicholas P., et al; "Effects of Hypnotic, Placebo, and Salicylic Acid Treatments on Wart Regression," Psychosomatic Medicine, 52:109, 1990.) Comment. The real import here is not in the vanquishing of these benign tumors caused by papillomaviruses but rather in the potential of altered states of mind for treating more severe afflictions, such as cancer.

Full-thickness dermal wounds were incised on the lateral deltoid region, using a skin punch biopsy instrument, on healthy subjects randomly assigned to treatment or control groups. Subjects were blinded both to group assignment and to the true nature of the active treatment modality in order to control placebo and expectation effects. Incisions were dressed with gaspermeable dressings, and wound surface areas were measured on Days, 0, 8, and 16 using a direct tracing method and digitization system. Active and control treatments were comprised of daily sessions of five minutes of exposure to a hidden Therapeutic Touch practitioner or to sham exposure. "Results showed that treated subjects experienced a significant acceleration in the rate of wound healing as compared to non-treated subjects at day 8." (Wirth, Daniel P.; "The Effect of Noncontact Therapeutic Touch on the Healing Rate of Full Thickness Dermal Wounds," Subtle Energies , 1:1 , 1990.
