Câu hỏi: With the onset of the winter season, man's natural enemies, the common cold and the flu, arrive with full force. It seems that the fluctuations in temperature and weather are guarantees that coughs and sneezes will spread inflecting germs among family and friends. More than 100 different types of bacteria can cause a cold, and doctors sometimes use antibiotics to treat bacterial colds. However, there are an equal number of viruses that can cause influenza, and modern science offers no drug capable of curing vital infections. In most cases, the best advice is the usual prescription: get plenty of rest, drink a lot of fluids, and be prepared to suffer for three to ten days. Some home cures help to relieve the symptoms of colds and flu. Mother's chicken soup, rich in fats and oils, helps to revitalize a tired body and to soothe a sorethroat. Garlic, containing the active ingredient allicin, has long been used to fight off the effects of bacteria and viruses. Hot toddies consisting of small amounts of liquor mixed with honey, sugar and lemon juice can relieve soreness and draw out cold germs. Finally, recent evidence suggests that large doses of vitamin C not only boost the immune system before a cold arrives, but also relieve cold symptoms after they have set in.
