Eating Gardenia jasminoides and blue light are both clinically used to treat jaundice in newborns. In comparison, the blue light is less harmful. Gardenia jasminoides, or Gardenia jasminoides granules, is a common clinical anti-yellowness drug, and can be taken by newborns to play the therapeutic effect of bile and anti-yellowness, but because Gardenia jasminoides is cut from the traditional Chinese medicine formula Artemisia jasminoides soup, it has the functions of clearing heat, dispelling dampness, and promoting the drainage of bile. It may also lead to discomfort such as redness and swelling of the skin around the anus due to an increase in the number of bowel movements. The most common clinical treatment for neonatal jaundice is blue light. Blue light is used to irradiate the skin of newborns with special wavelengths of light to induce the transformation of bilirubin in the body and its direct excretion through bile or urine, which can promote the rapid disappearance of jaundice in newborns, although diarrhea, fever, rash and other adverse reactions may occur, but generally the adverse reactions will gradually disappear after stopping the light treatment and the symptoms are mild. In addition, care should be taken to keep the newborn properly hydrated during treatment and to avoid prolonged exposure to blue light, which may lead to rash, fever and other adverse reactions. Although the two are relatively less harmful than blue light, in the process of treating neonatal jaundice, it is necessary to choose according to the specific condition under the guidance of a doctor, rather than blindly choosing a treatment method based on the size of the damage.
