Orthomolecular medicine is an unorthodox concept of medicine within the category of alternative medicine which recognizes dietary errors to be responsible for disease but which concentrates on using synthetic vitamins and minerals to achieve improved body chemistry. In addition, the patient is tested for specific allergies which are then eliminated, but in most cases as with other forms of alternative medicine, the gross fundamental dietary errors are not corrected. Orthomolecular medicine is a "patchwork" system capable of only partial results which may however appear good by comparison to conventional medical treatment.
