By mucus, I assume that you are referring to excessive mucus in the nose and throat, which is one of the typical symptoms of a common cold. While not particularly harmful, this can be extremely comfortable and irritating, and sometimes also leads to nausea when too much mucus ends up in the stomach.
Although there is no way to entirely solve the problem, some simple home remedies can provide adequate relief. First of all, drink plenty of fluids. This keeps the mucus lining moist and the mucus thin, enabling the cilia in the nose to efficiently clear the mucus along with bacteria, dust, and other particles. Hot soup, hot water (you can add honey or lemon or both), herbal tea, all help. You can also gargle with salt water to soothe the sore throat that tends to develop alongside such an infection. In addition, you can create your own nasal spray with salt water. Avoid smoke and pollution, and preferably avoid milk too, since it tends to worsen the condition in some people. Finally, get enough rest. People with colds and coughs tend to go about their business feeling mildly ill, since the sickness is relatively mild. However, exertion and stress can make things worse. If you can stay in bed, do so.
