We all have experience trying to manage mucus that is causing us a problem. Sometimes, such as during an upper respiratory infection, our bodies over-produce mucus, in which case we cough it up, blow it out, or “dry it up” with decongestants. Other times, mucus may become thick and crusted, in which case we thin it out by drinking more fluids, using a humidifier and Neti pot, or taking over-the-counter mucolytics. And, if mucus becomes purulent, we treat it with antibiotics.
