Allergies can affect the respiratory system such as house dust mites, cockroaches, household mould, pollen, passive smoking, or dust. Allergies from foods can have widespread effects throughout the body, including the digestive tract, skin, and respiratory organs. The allergen is the trigger of the allergic reaction, NOT the CAUSE. The cause of the allergy needs to be found and rectified. It usually has a direct link with the inability of the liver, digestive system or immune system to work effectively. Often common medications mask symptoms and have a rebound effect; the more you use them the more you rely on them.
Food and chemical sensitivity tests can be carried out to determine what your body is most sensitive to, eg wheat, dairy, pollen, mould. Allergies should be corrected carefully so as to monitor the liver function, digestive system and immune system.
