If a child’s cough gets worse after taking herbal medicine, this situation is mainly considered to be due to two conditions. First, it is caused by the wrong medicine. In this case, the cough is very serious after the child has bronchitis or pneumonia, but the medication is not very appropriate, thus the medication is not the right one, and the child’s cough will get worse. The child should be treated by changing the remedy in time and should not take the previous Chinese medicine. Secondly, it is caused by a condition that is getting better. Chinese herbs are often used to promote the lung and stop coughing, because after the child’s lung qi is declared, the cough will temporarily worsen, but with the aggravation of the cough and the sputum spitting out, the child’s cough will be significantly improved after 1-2 days. In this case, no special treatment is needed for the child’s condition, just continue with the medication.
