Generally speaking, children aged 2 years old can also take Han Xia granules, because the ingredients of Han Xia granules mainly include Han Xia and other drugs, which have good effects of resolving phlegm, relieving cough and lowering rebellion. If a child suffers from respiratory tract infection and has a cough with a lot of phlegm, as well as a thick and greasy tongue and a poor appetite, the application of Han Xia granules can play a good therapeutic role. However, when children apply the granules, the application dose must be under the guidance of a professional doctor, because it has a certain toxic effect. If the applied dose is too large and too long, it will often cause some digestive tract or liver and kidney function damage in children, so children can eat half of the granules when they are 2 years old, but they must follow the doctor’s instructions.
