It is defined as therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some, such as physical therapy, diet, and acupuncture, become widely accepted whereas others, such as humors or radium therapy, quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.
Alternative therapies include, but are not limited to the following disciplines: folk medicine, herbal medicine, diet fads, homeopathy, faith healing, new age healing, chiropractic, acupuncture, naturopathy, massage, and music therapy.
Studies suggest these therapies are sought out by individuals that have acquired immunodeficiency syndrome, arthritis, cancer, back pain, and other medical conditions.
