When it comes to sour food, many people's first reaction is vinegar. In fact, besides vinegar, there are many sour foods, such as hawthorn, tomato, kiwi fruit, grapes, pomegranate and so on. What can't taste sour is generally not sour food. First, most fires eat sour, eat your "internal heat" 1. When is it good for people with a big temper to eat sour? When you are angry, such as blisters on your mouth, acne on your face, and so on. Liver fire means that yin does not control yang, that is, less water and more fire. In order to put out the fire, you will add water, and acid will nourish the liver and yin, so that yin and Yang Can can be balanced. So it is good to eat some grapes, hawthorn, lime and other foods when you get angry. 2, aphtha, nasal cavity and skin dryness, sore throat and other phenomena Some people occasionally have dry mouth, sore throat, skin peeling and other phenomena, sour food has a convergence effect, eating more acidic food can converge lung qi, and second, it can nourish liver blood, thus achieving the effect of nourishing yin. Second, the sour health care recipe hawthorn porridge, Jianwei Xiaoshi went to the drugstore to buy some fried hawthorn, each time take 10 ~ 15g, soak in warm water for a while, then fry in the pot with clear water until the juice is left in the disposable cups (about 150ml), and then add 3 cups of water (about 400ml). Wait until the porridge is cooked before adding appropriate amount of sugar to taste. This recipe comes from porridge spectrum. Hawthorn itself has the function of promoting digestion. Compendium of Materia Medica holds that "hawthorn can be used for dietotherapy, eliminating accumulated meat, causing abdominal pain, excessive phlegm, fullness and acid swallowing, blood stasis and swelling", while japonica rice can "balance the qi of heaven and earth and benefit the stomach". Hawthorn digestion, plus japonica rice and stomach, the efficacy of digestion came out. Children who don't like eating at ordinary times and have poor digestion, or elderly people who are old and have decreased digestive function, can often drink this porridge, which has a good therapeutic effect on indigestion. Third, although sour taste is beautiful, people with spleen deficiency should avoid eating sour food, because acid entering the liver will make liver qi more abundant, and liver wood is spleen soil, which will make the weak weaker. Therefore, people with symptoms of spleen deficiency such as indigestion, loose stool and deep voice should eat less. If you suffer from gastric ulcer and hyperacidity, you should not eat it, otherwise it may aggravate the symptoms. People with cough and excessive phlegm, or diarrhea and dysuria should not eat acid, because acid has the function of "convergence", which is not conducive to the discharge of evil spirits. People with hyperglycemia, peptic ulcer or hyperacidity should not eat it. Then there are menstruating women, eating too much acid may lead to dysmenorrhea because of the convergence of acid. When taking drugs to relieve symptoms and sweating, vinegar should not be used. Because the acid has astringent taste, if it is taken at the same time with drugs such as compound Yinqiao tablets, it will shrink the sweat pores of the human body, which is not conducive to the discharge of pathogens. In addition, it will also destroy effective components such as alkaloids in traditional Chinese medicine. Therefore, you should not eat sour food when you have a cold.
