Based on your situation, if a child’s intellectual development is lagging and their worldview ability is weak, consider using traditional Chinese medicine decoctions for nourishment. Ginseng is particularly effective, but be aware that if the IQ is below the level of their peers, intellectual improvement through treatment is not possible. It is recommended to seek medical attention promptly and follow the doctor’s advice for symptomatic treatment. Additionally, pay attention to dietary issues and avoid eating spicy and irritating foods to prevent worsening of the condition. I hope these answers are helpful to you, thank you!
