There is no actual cure for the common cold, but resting, drinking more fluids and gargling the throat with salty water may help reduce symptoms, according to Mayo Clinic. Keeping the room warm and eating chicken soup may also counter the symptoms of the common cold.
Mucus production can make the body lose fluids, states Mayo Clinic. Drinking water, clear broth and other hydrating fluids, and cutting down on fluids that cause dehydration, such as alcohol, help to restore the levels of fluids. Dissolving 1/2 teaspoon salt in water and washing the throat with the solution may provide short-term relief. Chicken soup can fight inflammation and relieve congestion in the nose.
