There are many alternative medicines—from traditional Chinese herbs to probiotics—that might not be validated by the scientific community, but do in fact heal and cure sicknesses and ailments. Two new studies released by the National Institute of Health have found that as many as a third of Americans use some form of alternative medicine. The study talked to over 90,000 participants about their health habits and found that 1 in 10 Americans do yoga, about 8 percent of adults take fish oil supplements, and melatonin for children was the second most used natural product for adolescents.
