Do ear seeds work? If so, how?

PT Barnum. Ear sees are tiny black beads, which some individuals tape on different locations on the outer ear. They are used as a form of acupuncture. Whether or not they do anything helpful is in the eye of the beholder. They are not likely to hurt you in any manner except for thinning of the wallet. There are so very many "natural" remedies sold that have no concrete evidence of efficacy.
