Drink barley porridge for health in summer. From the point of view of TCM health preservation, barley porridge has two major functions: First, it strengthens the spleen and stomach. The second is to clear away heat and reduce fever. The temperature rises in summer, and there is plenty of moisture in summer, which easily leads to impaired spleen and stomach function, abdominal distension and loss of appetite. At the same time, the summer heat hurts the yin, making the population dry and bitter.
