Zheng's traditional Chinese medicine foot therapy for children is one of the representative therapies of the famous Chinese medicine family "Zheng's Red Medicine". "Baicao Qiongjiang" is its famous trademark, such as Baicao Qiongjiang brand Yiqi paste, Baicao Qiongjiang brand Yiqi ointment, etc. It has achieved great success in treating cough, phlegm and asthma in children, and has become the most representative prescription for external treatment of internal diseases in the north. Zheng's traditional Chinese medicine foot therapy for children has also benefited many children because of its safety, convenience, obvious effects and low price.

Professor Zheng Yanming, the third generation descendant of "Zheng's Red Medicine", an expert in the treatment of internal diseases and external medicine, and a famous domestic old Chinese medicine practitioner, believes that in the current Chinese medicine foot therapy for children, many products are just a collection of traditional Chinese medicines and pharmaceuticals. The resuscitation effect of the drug is not obvious, and the penetration of the drug is slower and less, making the health care treatment effect unsatisfactory. A good external medicine formula should have the characteristics of being able to penetrate the skin, carry the medicine directly, promote the skin's selective absorption of medicines, and be scientific in the compatibility of medicinal materials. The composition of the prescription only requires a few flavors of traditional Chinese medicine to achieve the effect of making a huge difference.
