In food and drinks there are no restrictions. On the contrary whatever food and drinks your previous doctor had told to avoid, should be tried first! This sounds ridiculous. But there is a strong reason for it. As we already discussed above, that Homoeopathic medicines treat the cause and not the effect. The impaired immunity or resistance of the child is what makes the child suffer from various infections. The cold drink, ice creams, the dust, or any other allergy giving substance is affecting the patient because the immunity of the patient is not good. Other children or members of the family can tolerate the same things very well without making them ill then why not this child? This means it is not these substances that are to be blamed as causative factors, but the decreased resistance the patient. Improve the resistance of the person and the same aggravating factors shall not make him ill. Homoeopathic medicines are like vaccinations that make a patient immune to these factors, and on the contrary these factors that make him ill should be tried to ascertain whether the medicines are working properly or not and the child is getting immune or not.
