Stomach yin is mostly caused by epigastric pain for a long time, irregular diet and daily life, body fluid injury in the late stage of fever, or spicy food, or stagnation of qi and fire, stomach failure to nourish qi, and endogenous deficiency heat. Dull pain in the epigastric cavity, burning pain, hunger, abdominal distension, retching and burping, vomiting, dry mouth and throat, and dry stool; Red tongue with little fur and thin pulse.

From the perspective of Chinese medicine, frequent staying up late, poor sleep quality and long-term mental stress may all lead to insufficient stomach yin. According to the theory of five elements, the stomach belongs to "dry soil" and "likes moistening and hates dryness". Like a dry land, it hopes to be nourished by water.

From the aspect of sleep, "deep sleep is the method of nourishing yin" is a famous saying of Chinese medicine. If a person's sleep quality is not high, it is easy to "secretly consume vaginal fluid". In addition, human sweat also belongs to "vaginal fluid". "Many people can't eat in hot summer and sweat a lot, which also has a lot to do with the damage of vaginal fluid."

At the same time, Chinese medicine believes that the relationship between liver and stomach is also very close, and the transport function of spleen and stomach depends on the release of liver qi. "And nervousness, anxiety, depression, anger and other emotions are easy to hurt the liver, and a series of digestive tract symptoms, such as loss of appetite, bloating, stomach pain, vomiting, belching, etc."

Dendrobium, lily, yam and Polygonatum odoratum are all medicinal materials that can nourish stomach yin. People can choose one or two kinds of soup to eat according to their own tastes, such as fresh lily crystal sugar water, yam lean broth, Dendrobium stew meat pie, etc., all of which are delicious and can nourish the stomach.
