Now a days Milk intolerance is a common food intolerance among children and adult also. It results from an over reaction of the immune system towards the protein in the milk or milk products. In children or a person who are intolerant to milk, the immune system recognizes the protein in the milk as a harmful foreign substance and starts an immune reaction to fight against it. These symptoms related to this immune reaction varies from person to person. Homoeopathic medicines treat milk intolerance by optimizing the immune system. Once the immune system is moderated, the intensity and severity of the symptoms get reduced.
