Second, it should be suitable for people. For example, Radix Pseudostellariae and Radix Astragali are both drugs for invigorating qi, but their usage is different. If the child has dry mouth and throat and dry stool, it is a hot constitution. Pseudostellaria heterophylla can be used to cook porridge and nourish qi and yin. If you are afraid of the wind, cold and cold, cook porridge with astragalus to help warm the sun. Walnut kernel and yam are both tonics. People with constipation should eat walnuts, while people in loose stool should eat yam.
Third, we should pay attention to the taboos of collocation and compatibility. Lycium barbarum can tonify kidney, replenish essence, nourish liver and improve eyesight, but it is not suitable for people with mild internal heat. White chrysanthemum can refresh the brain, calm the liver and improve eyesight, but it is not suitable for people with slight cold and yang deficiency. Making tea with medlar and chrysanthemum can complement each other.
Finally, we should pay attention to the right amount. A normal and reasonable diet with three meals a day is the main source of human nutrition and the most routine tonic. The most important thing on the eve of the senior high school entrance examination is to ensure the reasonable and comprehensive nutrition of candidates' three meals a day. Overtaking will affect your health.
