CONSTITUTION: This rhinitis treating agent contain one component or plural components in α-linolenic acid-based oil and fat containing a highly unsaturated fatty acid of α-linolenic acid, eicosapentaenoic acid, docosahexaenoic acid and these derivatives. A vegetable oil such as perilla oil, linseed oil and egoma oil rich in α-linolenic acid, fish oil of horse mackerel, sardine, Pacific saury, etc., rich in eicosapentaenoic acid and docosahexaenoic acid or oil and fat of sea grasses can be used as origin of the α-linolenic acid-based oil and fat. An antioxidant such as vitamin E, vitamin C, carotene or tea catechins can be blended in addition to α-linolenic acid-based oil and fat. Though the nasal drop is preferably dropped, jetted or sprayed into nose cavity, the drop may be applied to the surface of nasal hole. α-Linolenic acid-based metabolism suppresses metabolism of linolenic acid and relieves allergic symptom. |
