The best way to treat a cold is to drink plenty of water, get enough sleep and fumigate the air with vinegar. There is nothing wrong with drinking less vinegar, which is also helpful for treating colds, but not too much, let alone medicine. This situation must be taken with water. Maybe it's psychological. There is no medical basis for thinking that vinegar can sterilize and drinking vinegar can treat colds, but vinegar can be smoked indoors frequently, which can prevent the reproduction of bacteria and other microorganisms. I suggest you exercise more to improve your physique and take cold medicine for treatment. A cold is mainly a respiratory infection. You can smell vinegar with your nose every day to kill the virus in the respiratory tract. Drinking vinegar means drinking vinegar into your stomach, which has little effect on colds.
