In our life, we often hear children say that they have stomach pains, except for a few organic ones, most of them are functional, which is what we verbally call indigestion. Many parents are troubled by this symptom from time to time, and they run through hospitals of all sizes, but the ultrasound of the abdomen indicates enlarged mesenteric lymph nodes and no other abnormalities. It seems to be better with anti-inflammatory drugs, but it comes back in a short time. We have developed a Chinese herbal medicine for external treatment, Rizhong San acupuncture point application, which is convenient and simple, and is loved by parents and children. It not only cured the abdominal pain, but also had the effect of strengthening the spleen and opening the stomach. I was deeply relieved to see that the children were not sick without injections and fluids, which is perhaps the greatest reward for a TCM pediatrician!
