Don't eat candy bought outside, it's not safe. If you feel bitter after drinking Chinese medicine, you can eat a small piece of rock sugar after drinking it. Cooking can be eaten, but don't put irritating spices. Like peppers. I have this disease, too. Usually there are only three kinds of seasonings in the dish, soy sauce, vinegar and salt. Soy sauce vinegar will also choose to eat less additives. There won't be much salt. I hope your child will recover soon.
