“How many milliliters of Chinese medicine should a child drink each time” is not clearly defined, and the dosage of medicine for children of different ages is different, divided into the neonatal period, early childhood and school age. 1. Neonatal period. The dosage for newborns is one-sixth of the dosage for adults, e.g., if the dosage for adults is 400 milliliters, then the dosage for newborns should be about 50 milliliters. 2. Early childhood. The daily dosage for toddlers and young children should be about two-thirds of the adult dosage, usually around 250 ml. 3. School age. The dosage of herbal medicine for school-age children is generally the same as that for adults, which is around 400 milliliters. The above is the common dosage of Chinese medicine for children of different age groups, and the specific medication should be consulted with the advice of a medical professional.
