Expectorants work by thinning and loosening mucus in the airways, thereby facilitating its expulsion when coughing. This process not only helps clear the airways but also promotes better breathing and comfort. Generally, the primary active ingredient in expectorants is guaifenesin, a well-known compound found in many over-the-counter medications. It is important to note that while expectorants help relieve symptoms, they do not cure illnesses. Instead, they support the body’s natural healing processes.
