Homeopathy is a therapeutic system of medicine based upon the "law of similars" - "let like be cured by likes." This means that a substance administered in large crude dosages to a healthy individual will produce specific symptoms, but when the same material has been reduced in size and administered in minute doses, it will stimulate the body's reactive process to relieve these same symptoms. Homeopathy is used to treat acute and chronic conditions. It may be given in liquid, pellets, or tablets. Remedies are very palatable and quite popular with children.

Homeopathic remedies can be given in place of some vaccines or to lessen the side effects of the vaccine.
