Any home remedies for a wet cough and runny nose?

Daily saline irrigation 1 to 2 x daily on the nose may reduce the cough. If you are allergic to outdoor allergens, staying in an air-conditioned room during the pollen season may help. Pets may be a problem. No home remedies has been found to be that effective.
