When a child has yellow nasal discharge after catching a cold, it may be a wind-heat cold, or it may start as a wind-cold cold. However, for a slightly longer period of time, the disease will enter the inside and turn into heat, so they will have a slightly yellow runny nose. If the symptoms of runny nose at this time are not too severe, you can focus on the most serious symptoms after the cold, such as fever. At this point, some fever-reducing medication should be applied to bring the child’s temperature down to normal. If there is no fever and other discomfort, only the runny nose, usually not a big problem, the runny nose can be applied to the treatment of drugs. If it is a wind-cold cold with heat, Chinese medicine can be prescribed using the formula of Nine-flavored Qiangwu Granules or Nine-flavored Qiangwu Tang. Many of the pungent and warm medicines in it have the effect of clearing the nose, and there is also Scutellaria in it to clear the heat evil. If it is a wind-heat cold, you can take Vitamin C Yin Qiao tablets or the corresponding preparations, which can clear heat and clear wind.
