Experts: Placebo power behind many natural cures
By MARILYNN MARCHIONE, AP Medical Writer Marilynn Marchione, Ap Medical Writer – Tue Nov 10, 3:16 pm ET
EDITOR'S NOTE: Ten years and $2.5 billion in research have found no cures from alternative medicine. Yet these mostly unproven treatments are now mainstream and used by more than a third of all Americans. This is one in an occasional Associated Press series on their use and potential risks. ___ People looking for natural cures will be happy to know there is one. Two words explain how it works: "I believe." It's the placebo effect — the ability of a dummy pill or a faked treatment to make people feel better, just because they expect that it will. It's the mind's ability to alter physical symptoms, such as pain, anxiety and fatigue. In just the past few weeks, the placebo effect has demonstrated its healing powers. In tests of a new drug to relieve lupus symptoms, about a third of patients felt better when they got dummy pills instead of the drug. The placebo effect looms large in alternative medicine, which has many therapies and herbal remedies based on beliefs versus science. Often the problems they seek to relieve, such as pain, are subjective. "It has a pejorative implication — that it's not real, that it has no medicinal value," said Dr. Robert Ader, a psychologist at the University of Rochester in New York who has researched the phenomenon. But placebos can have real and beneficial effects, he said. "Much of the results of certain alternative procedures are largely placebo effects, unless you believe there are people who exert magical powers so they can hold their hands over your body and cure you of disease," Ader said. "Make you feel better? That's entirely possible, especially if you believe it." The placebo effect accounts for about a third of the benefits of any treatment — even carefully tested medicines, scientists say. This dates to a landmark report in 1955 called The Powerful Placebo. Viewed as groundbreaking, the analysis of dozens of studies by H.K. Beecher found that 32 percent of patients responded to a placebo. Later studies found that dummy pills could raise pulse rates, blood pressure and reaction speed when people were told they had taken a stimulant; the opposite occurred when people were told that a drug would make them drowsy. How does it work? Scientists do not always know, but there are many possible ways. Brain imaging shows that beliefs ("I know these pills will help") can cause biological changes and affect levels of chemical messengers and stress hormones that signal pain or pleasure. Emotions, too, can trigger physical changes. Take the case of a child with croup. Crying tightens the airways and makes it tougher to breathe. Many people believe that cool mist is helpful, but when it has been tested in hospital studies with croup tents, it has not been found to help, said Dr. Owen Hendley, a pediatrician at the University of Virginia. Try it at home, though, and you may get a different result. "The child sits in the lap of the mother and the mother holds the mist maker close to the child. The child settles down, the mother settles down. The setting, and the mother feeling that it is helping, makes everybody calmer," and the child actually is able to breathe better, Hendley explained. If it were not for the placebo effect, "physicians would not be nearly as successful as we are," said Dr. Thomas Schnitzer, a Northwestern University arthritis specialist. He helped lead a big study that found glucosamine and chondroitin supplements were no better than dummy pills for arthritic knee pain. Doctors sometimes exploit the placebo effect to help patients. One survey found that many doctors admitted sometimes giving patients sugar pills or drugs or vitamins that would not really help their condition, in an effort to trigger a placebo effect.

Re: Experts: Placebo power behind many natural cures
Bull-oney, and what a freakin waste of money!!!
Nutrients work. Herbs work. Homeopathics work. Orthomolecular works. The list goes on and on. You can set up a study to prove anything you want to. You can even write the abstract to say something the study did not prove. |

Re: Experts: Placebo power behind many natural cures
There is a placebo effect and it is just as common in allopathic (mainstream) medicine as it is in alternative - I remember a fairly recent headline about that also.

Re: Experts: Placebo power behind many natural cures
Nice, this is actually a subconscious work, the brain knows that it is receiving medicine and if the doctor saids that (a person in which the brain "trusts"), the brain will create those effects.
If you keep telling yourself that you are cured, that you are felling well, sooner or later that effect will take place. This is how hypnosis work, get inside your subconscious and fix some belief system. I remember my grandmother getting drunk with grape juice, thinking it was wine, she got red and dizzy......... very funny. |

Re: Experts: Placebo power behind many natural cures
It only proves that we can heal ourselves if we believe we can...
