Alternative Medicine
Throughout recorded history, people of various cultures have relied
on what Western medical practitioners today call alternative medicine.
The term alternative medicine covers a broad range of healing philosophies,
approaches, and therapies. It generally describes those treatments and
health care practices that are outside mainstream Western health care.
Worldwide, only an estimated ten to thirty percent of human health care
is delivered by conventional practitioners. The remaining seventy to
ninety percent ranges from self-care to care given in an organized health
care system based on alternative therapies.
The number of people using alternative therapies is staggering. In 1991
about twenty-one million Americans made four hundred and twenty-five
million visits to practitioners of these types of alternative medicine;
more than the estimated three hundred and eighty-eight million visits
made to general practitioners that year. Americans
spend thirty-four
billion dollars on alternative medicine annually. The U.S. Department of Education
has accredited more than twenty acupuncture schools and more than thirty
medical schools now offer courses in acupuncture.
Critics say a definitive scientific answer must await well-designed
experiments involving many patients. Mainstream
scientists often criticize alternative medicine as charlatanism, arguing
that anything alternative that's been proven to work is in fact...mainstream
medicine. Advocates of alternative medicine, in contrast, typically
point to their personal experiences as proof of the effectiveness of
such interventions.
Some alternative treatments, such as acupuncture and herbal medicine,
have impressive histories dating back thousands of years. In America,
professional and public interest in the field of alternative care has
grown to such an extent that, in 1992, the U.S. government established
the Office of Alternative Medicine within the National Institutes of
Health. Its mission is to speed the discovery, development, and validation
of potential treatments to complement the current healthcare system.
One of the its first tasks was to develop a classification system for
the dozens of various therapies and practices. The systems of alternative
medical practice the OAM has classified so far share many common therapeutic
techniques.
Following are some the more popular alternative therapies Americans
use.
Acupuncture
Acupuncture is an example of a therapy once considered bizarre which
has some scientific basis. It is based on the belief that energy, which
the Chinese call Qi (pronounced 'chee'), circulates along meridians [
] in the body in
the same way that blood flows. A diagram [ai] of the meridian system
looks similar to those of our circulatory and nervous systems. When
the flow of energy becomes blocked, an imbalance is created, resulting
in pain or disease. To restore the proper balance and energy flow, acupuncturists
stimulate specific points of the body along these meridians. Puncturing
the skin with a needle is the usual method, but acupuncturists may also
stimulate the acupuncture points with finger-pressure.
Although Western physicians and researchers do not truly understand
the concept of Qi, there is evidence that acupuncture can influence
the movement or release of many chemicals in the body. Researches established
that acupuncture releases naturally produced, morphine [
] like substances
called endorphins.
In addition to releasing endorphins, doctors and clinicians know that
acupuncture can provide at least short-term relief for a wide range
of pains by inhibiting the transmission of pain impulses through the
nerves.
Furthermore, recent studies also show acupuncture to be effective in
alleviating bronchial asthma, bronchitis, and stroke-induced paralysis.
Mind-Body Healing
Relaxation techniques like meditation and biofeedback--which teach patients
to control heart rate, blood pressure, temperature and other involuntary [
] functions through
concentration--have also given respectability to alternative medicine
and are often taught to patients and medical students. The basic premise
of mind-body medicine is that the power of the mind can be used to help
heal the body by improving the person's attitude and also, as recent
research has shown, by direct effects on the immune, endocrine [
], and nervous systems.
Although many of the biochemical and physiological mechanisms remain
to be identified, an increasing body of evidence is showing that the
healthy mind is indeed capable of mobilizing the immune system-and that
the troubled mind can dampen the functioning of the immune system and
contribute to physical disease.
There is little doubt that state of mind and physiological processes
are closely linked. The connection between stress and immune system
response, for example, is well documented. Some scientists suggest that
the power of prayer and faith healing, like some forms of meditation,
might also be physiological in that they may protect the body from the
negative effects of stress hormones. In addition, experience shows that
relaxation techniques can help patients enormously.
In addition to preventing or curing illnesses, these therapies provide
people the chance to be involved in their own care, to make vital decisions
about their own health, to be touched emotionally, and to be changed
psychologically in the process. Many patients today believe their doctor
or medical system is too technical, impersonal, remote, and uncaring.
The mind-body approach is potentially a corrective to this tendency,
a reminder of the importance of human connection that opens up the power
of patients acting on their own behalf.
Conclusion
Many Americans flock to alternative practices either because their suffering
has not been alleviated by standard medical or surgical treatment, or
because the traditional treatments themselves are too expensive or dangerous.
These patients often feel that the intrusion of increasingly complicated
and impersonal technology has widened the gap between mainstream caregivers
and patients. Too many doctors are thought to be coolly professional
and emotionally distant, inclined to cure a specific disorder narrow-mindedly
without comforting or caring for the patient. Americans have made it
clear with their pocketbooks that they find this unacceptable.
The power of the mind-body connection has been confirmed from many scientific
studies. I think in some conditions a person's belief alone can dramatically
eliminate their symptoms. There have been hundreds of popular remedies
found that have proven to be ineffective or sometimes even harmful.
Herbal remedies and many folk remedies have not survived scientific
testing for many years now, and if they did they would stop being "alternative
medicines" and become a part of scientific therapies. I think if
a person is using a harmless remedy and they really believe in it, then
using it will help improve their condition. The bottom line is that
we just don't know what these substances are doing. They many be inactive,
or they may have activity independent of their powerful belief effect.
They could match up with their advertised uses, or they may be effective
for something entirely different. They could very well be harmful. Many
unmodified plant products do not have near the amount of predictability
that regular medicines have. People that are taking herbal remedies
are engaged in a big natural experiment with many untested substances.
Before people turn to alternative medicine it is important that they
research it as much as possible so they have some idea of what they
are getting in to, and they really better believe in it.
