A cold, also known as an upper respiratory tract infection, is very common clinically. Most cases are caused by decreased immune function in patients, who may accidentally get chilled, wet in the rain, or directly infected by others with a cold. Typically, if a patient with a cold also has a cough, it is mostly due to viral infection. Thus, such cases are considered self-limiting diseases clinically. Therefore, we generally advise patients with colds to drink more water and eat more fresh vegetables and fruits. Additionally, consuming more of certain fruits like pears, loquats, strawberries, water chestnuts, and particularly bayberries, which are very common and nutritionally rich in organic acids, cellulose, fats, beta-carotene, vitamin B, and vitamin C—all essential for the body—is recommended. Eating bayberries can be beneficial for cold and cough patients and aid in faster recovery from the illness.
