Mind/Body Medicine. Guided imagery, meditation and other practices that harness the mind to promote health and healing have been adopted by conventional medicine as a means of managing stress and pain. While a recent analysis of 813 studies concluded that "no compelling evidence" exists yet to prove the theurapetic value of meditation, some studies have suggested that mind/body exercises, in conjunction with conventional methods, can help treat cardiovascular disease and even bolster the immune system. That these methods pose no physical or psychological risk to the patient and are inexpensive adds to their appeal. Among mind/body interventions, one of the hottest research topics is the placebo effect: Doctors want to know whether a patient's expectation that a treatment will work ultimately affects that patient's outcome.






Herbal Therapies. Herbal medicine is "easier to present to med students [because] it's a bit closer to pharmacology" than some other CAM treatments, says Rick Scott, of the University of Maryland's Center for Integrative Medicine in Baltimore. But he agrees with Mary Jo Kreitzer, a founding member of the medical school consortium, that herbal medicines remain controversial, with a lot of uncertainty about how safe they are and how well they work.

St. John's wort, for example, may be useful in treating mild (but not moderate to severe) depression; however, because the herb can alter the way the body processes drugs, it should be used with caution. Another example: In a recent study, black cohosh did not help ease menopausal hot flashes.

Among biologically based treatments that do not involve herbs, studies of dietary supplements such as glucosamine (to treat arthritis) and echinacea (for upper respiratory illness) have been inconclusive, while evidence supporting folic acid's utility in preventing certain birth defects has been convincing.


Manipulative and Body-Based Methods. The science behind chiropractic treatment, massage therapy and other practices in which the body is physically manipulated to promote good health is sketchy and inconclusive, according to a review of research by the NIH's National Center for Complementary and Alternative Medicine. It's particularly hard to study methodically and to measure results. Still, Cirigliano says of chiropractic treatment, "The only issue I have with [chiropractors] is that they know their limitations. They're not going to cure lung cancer."


Energy Medicine. According to Scott, "The area that will take a little bit longer is frontier medicine, or energy medicine. It's more difficult to research" than conventional medicine because, like acupuncture, it's founded on a belief in energy fields. This category includes such approaches as therapeutic touch, distant healing, prayer, and the laying-on of hands. ·

Earning money online through eHow

Articles are created by a small group of eHow staff and experts, and a much larger group of writers who (much like at Knol) contribute what they want, when they want, and as often as they want, as long as they are in keeping with eHow guidelines.

eHow is a popular, highly-trafficked site. In December 2008, it had an Alexa ranking of 476, that is, the 476th most popular site on the internet.

Through the eHow Writers' Compensation Program, writers can earn income for their contributions (currently, only those based in the US can participate in the WCP, though eHow intends to expand the program internationally in the future). Although eHow content is largely text-oriented, it is also possible to include images and videos with an article. The site operates on an advertising revenue-sharing model; the more ad income an article earns, the higher the earnings for the author.

Earnings for individual articles are highly variable, though over the long term, a writer for eHow typically earns about one dollar a month for every article posted. Several WCP writers have hundreds of articles to their name, and are earning hundreds of dollars per month (my own payments are approaching $1000 per month after eight months of participating in WCP). The most experienced writers at eHow earn over $2,000 a month and have seen steady increases in their earnings. Payments are made each month through PayPal.

Assuming that the eHow revenue-sharing model remains intact, the earnings potential at eHow is quite high. A single article (which typically represents 30-60 minutes of preparation time) can conceivably generate several hundred dollars in income over the space of a few years. There is no limit on the number of articles an author can contribute.

There are many other web-based opportunities for earning income by providing content to revenue-sharing sites. From my experience with several of these sites, and the experience of other WCP writers, eHow is far and away the easiest way to begin generating a steady, and steadily growing, stream of revenue. One of the most prolific writers at eHow, my colleague WriterGig, has written an eBook on how to earn $1,500 a month (or more) at eHow. Another of the site's star writers, Janet Ford, has also written a book on maximizing your income at eHow.

I will be more than happy to answer any questions or respond to comments about eHow, so please let me know your thoughts, below.
