Let us consider a case where say an antibiotic is being given for an infection but the patient believes it to be a deadly poison and with some preparation in the effect of being poisoned manages not only to regurgitate the pill but enough stomach acid that being inhaled causes a lung malfuction resulting in death. Clearly antibiotics fail and result in death. In another case a patient believes that a copper band or a magnet will relieve arthritic pain and experiences the relief. I know a hypnotist that keeps terminal cancer patients alive for twelve years or more after their Oncologist has told them to expect to die in three months. Clearly the substance that takes effect in the body does not do so out of respect for the chemicals in the substance or the lack. The mind as the prime material of the body, responsible for maintaining the shape and function of the body, is the actual recipient of the remedy, and if the mind chooses to regard the remedy as of benefit then a benefit will result. People who are by parental example taught that a Doctor is sincerely related to a state of health will get some result out of whatever is prescribed, including Placebos. Some chemicals can destroy bacteria and some will force the brain to work faster or slower. These effects can be minor or even irrelevant depending on the belief state of the patient. In trials using hypnosis a man can be burnt by a pencil if he believes it is a hot poker, or a knife can be passed through a body from side to side leaving no wound or scar. At that point I am annoyed. Everybody ought be trained to instantly heal wounds and the technique has been brought to demonstration but not to application. The human body is not simply a factory where you can add ingredients and get products but is a collection of mud held together by a mind. The mind itself can be shown to interact with electricity, magnetism, and gravity. In certain rare cases it can explode the body or cause it to rise into the air. Probably what is needed is a carefully standardized set of placebos with good hynotic associations then the appropriate idea being elicited by the standardized placebo a wound would instantly repair as in the knife demonstration, a cancer would regress as in the cancer regression hynotherapy, or any mental or physical state would correct to a desired course, but this inevitably takes more skill and training of the physician. Some chemicals such as an antacid or an analgesic can be found to work without a lot of preparation, at some point this easy way has become the only way, but it can be found that the healer Priests in both Greek and Egyptian sanctuaries of healing placed no absolute reliance on either mental or physical remedies but importantly learned to do what worked in the situation, given the variety of responses some details of known Allergies and other sensitivities go into making healing a more responsible process.
I am a trained student of the Rosicrucians and have also been taught Pharmaceutical Chemistry as a subject in addition to what I had to learn to get a College Certificate in Chemistry.
