Low dose immunotherapy (LDA/LDI) is Dr MacIver’s single best tool to treat immune overactivity and allergy. This treatment is effective for most allergies, chemical sensitivity, autoimmunity, chronic infections, and symptoms from mold illness. The treatment involves administering very diluted (homeopathic) formulas customized for you, to induce tolerance to your sensitivities. Commonly used formulas include foods, inhalants, chemicals and molds.
