It depends on the ingredients of the old fire soup. The older generation thinks that children are weak all day, look pale and easily get sick, so they will judge that children need to make up for qi deficiency. They often cook things such as salvia miltiorrhiza, pseudostellaria heterophylla and American ginseng for their children, and they think that ginseng is beneficial to qi and can enhance their resistance. But this old fire soup is not good for children, because this old fire soup has an impact on children's spleen and stomach function. But not all old fire soups can't be drunk. It depends on the ingredients. The conditioning for children is mainly the spleen and stomach function. We recommend children to drink some soup that strengthens the spleen. After the illness, children are in the state of spleen deficiency, so they can drink some soup for strengthening the spleen, but they don't advocate drinking it every day, once or twice a week. It is recommended to drink some soup of drugs that strengthen the spleen and stomach, such as yam, poria cocos, Euryale ferox and lentils. It should be emphasized that the soup should not be too nutritious. Some parents put a lot of bones, meat, etc. in the soup. They think that the bowl cooked is thick enough for nutrition, but it is actually unnecessary.
