Mugwort has the effects of removing cold, warming the meridians, and regulating qi. It has certain antiviral and bactericidal effects and can have a certain therapeutic effect on treating eczema. Mugwort treatment for eczema can take two methods: medicinal baths and oral administration. Generally, children use medicinal baths for treatment, but mugwort cannot completely cure eczema; it can only help alleviate the condition. Therefore, it is important for children to maintain a light diet, avoid contact with allergens, and it is best to go to the hospital for detailed and scientific diagnosis and treatment.
