Research claims to have confirmed the efficacy of homeopathic medicine and the old idea that it only worked psychologically has been disproved.

Infants: Homeopathic medicines and treatments are successfully used by parents for common infant ailments such as colic, teething pain and some infections.

The effects of homeopathic medicines have been observed repeatedly on neonates, unconscious patients.
