In traditional Chinese medicine, it is believed that wind-cold common colds mainly occur when the body's resistance is lowered and is exposed to wind-cold. If one catches a wind-cold common cold, it is necessary to appropriately take some medicine that expels wind, resolves the exterior, and dispels cold. In daily life, one can use ginger brown sugar water to expel wind and disperse cold. Ginger has the effects of inducing sweat, resolving the exterior, and dispersing cold, while brown sugar warms the middle and boosts yang. Used together, they can treat wind-cold common colds. Additionally, drinking some hot porridge to induce slight sweating can also help expel wind.
