The nocebo effect is a term that illustrates a negative effect because of the power of belief. The nocebo is when you give a normally "effective" drug to a patient, but there is no response because the doctor has convinced the patient the drug wouldn't work or was just water. Anything can serve as a nocebo just as anything can serve as a placebo -- medication, location, doctor's manner, etc. For instance, if you were told you had a heart disease, and believed it, you might easily die of it -- even if later it was found that your lab test results were mistakenly switched with another patient's.
Could good health be as simple as -- "If you believe you deserve to be healthy and expect to be, you will be?!"
