In general, children with gastric fever often have red lips and tongue, bad breath and even vomiting, which is mainly due to the fact that children usually like to eat high sugar and fried food. Some children have very dry stools, a yellow tongue and a distended abdomen. For children’s stomach heat, it can be treated by removing stomach heat, such as applying gypsum, scutellaria and dandelion in water, which can significantly improve children’s stomach heat and relieve their poor appetite and vomiting symptoms.
