Eating oranges can help alleviate the symptoms of a cold. Oranges are rich in various vitamins and contain a lot of water. They help moisten the lungs, stop coughs, and enhance the body's immune system, aiding in the relief of symptoms. During a cold, it is also important to increase nutrition by consuming high-quality, high-protein foods such as milk, beef, and lean meats to replenish energy. If cold symptoms are severe, such as headaches, nausea, and high fever, one can take traditional Chinese medicine anti-cold treatments under the guidance of a doctor, such as Lianhua Qingwen capsules. If a secondary bacterial infection occurs, presenting symptoms like fever, cough, and yellow sputum, use antibacterial medication prudently based on the results of sputum culture and drug sensitivity tests, such as azithromycin or cephalosporin antibiotics.
