Allergen immunotherapy (slowly increased exposure to allergens) is sometimes suggested for environmental allergies (such as insect bites or asthma) but not generally accepted for allergies such as food allergies. The reason for this is that there is scientific evidence that the benefits outweigh the risks. What's more is that it isn't just administered in blindly increasing amounts; the histamine reaction in the body is carefully measured and doses of the allergen in carefully calibrated to match. But this is just one small part of medicine. Almost no other medical treatments have such evidence which is why homeopathy is labelled as having no evidence to support it and that is being generous as plenty of people have gone looking for evidence to support it but there is no credible evidence to be found after 100 years of trying.
