Newborn babies with jaundice are able to drink corn husk water. Because Chinese medicine believes that neonatal jaundice is caused by dampness and heat in the body, and corn husk, has the effect of clearing heat and dampness. The action of corn husk water is very gentle and suitable for newborn application, and long-term application will not cause symptoms of yin injury. However, parents must be aware that jaundice in newborns can cause bilirubin encephalopathy, and the consequences of nuclear jaundice, if the jaundice is particularly severe and the bilirubin level is very high. In this case, it is not possible to apply corn sap water alone, but to monitor the jaundice level dynamically, and if the jaundice value is progressively increasing, parents should promptly administer blue light to the newborn, or even to perform therapies such as blood exchange. The simple application of cornstarch water can sometimes delay the child’s illness, and parents must be aware of this.
