Sinusitis Oral Liquid is mainly used clinically for the treatment of acute and chronic rhinitis and sinusitis, and its normal dosage is 10ml/time, 3 times/day. For three-year-old children, we can use 2-3ml, 3 times/day, and need to reduce the dosage as appropriate. Sinusitis Oral Liquid is mainly due to the composition of Chinese herbs such as thorny mustard, peppermint, dahurica, and also celosia. The clinical effect is aromatic and clear, and because of the nature of the oral liquid, it is relatively suitable for children. However, it should be noted that it should not be used for patients with clear and dilute nasal discharge because it is a cold evidence according to the theory of Chinese medicine. It should be used by children under the guidance of adults (and physicians), and the drug should not be placed in places easily accessible to children anymore.
