Why are there some scattered medicines in each bag besides small packages of traditional Chinese medicine?

Decoct the powder in groups (normal decoction is enough). Small bags are different. Some are decocted first (15-30 minutes ago, and the medication time is different), some are decocted later (meaning the same as the first decoction, but the time is according to the doctor's advice), and some are decocted in packages (usually the medicine with smaller powder or particles), so the doctor will explain it every time you take medicine, so remember it well, otherwise it will happen.
