Alternative and traditional medicines have varying degrees of effectiveness. While some alternative therapies like herbs have benefits and are potentially effective for prevention, reliance on unproven alternative or traditional methods could endanger one's health. The study reviewed various alternative therapies like herbal medicine, chiropractic, Reiki, and faith healing. It found that some therapies like Reiki have not been proven to have medical effects and may work through placebo effects from the patient's beliefs. The researchers concluded that using a combination of proven alternative therapies along with conventional medicine is likely most effective, rather than solely relying on unproven alternative or traditional methods.
