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. Chinese medicine believes that barley enters the spleen and stomach. Sticking to eating barley porridge in summer can nourish yin and stomach and promote digestion. In summer, many people will find the heat unbearable. In fact, there are two kinds of summer heat, one is internal heat and the other is external heat. Air conditioners and electric fans can only help people sweat and relieve exterior heat, while barley is cold, which can not only relieve exterior heat, but also eliminate internal heat such as stomach discomfort, dry mouth and bitter taste.
