At the first sign of a cold, which usually includes chills, stiffness, and fatigue, take a diaphoretic herbal tea or pill remedy (cinnamon tea or Gan Mao Ling); wrap up in warm sleepwear, go to bed, and take a sweat-bath vacation for about an hour. Then eat warm barley soup during the rest of the day to clear phlegm. You will tend to have more congestion symptoms if your diet is rich, creamy, sweet, and fatty, because those foods slow digestion and create phlegm.
