A medicinal formula is created after one becomes deeply familiar with the properties of various medicines, using the principle of balanced combinations to achieve different effects.
However, formulas made from herbs mostly lack universal applicability. They must be tailored to the individual. Therefore, a Physician often needs to observe the patient before prescribing a specific dosage.
But one type of medicine is different: universally applicable medicine.
It doesn't require a Physician to prescribe a specific dosage; you can simply buy it and use it.
Ordinary Physicians can't create this kind of medicine. They are still in the learning stages of their craft. Only a veteran Physician could possibly develop such a universally applicable medicine—one that seems simple but is actually incredibly difficult to create.
