The main and auxiliary materials required are not many in quantity.
Although the pill formulas of such kinds often have many deficiencies when refined, they have the advantage of simplicity, and the medicinal power is influenced by the main material—the better the main material, the stronger the medicinal power!
And then there were the pill formulas that appeared after ancient times, which are those of recent times.
As the availability of high-quality medicinal ingredients from previous years has declined, the ratios of auxiliary materials used have become increasingly numerous.
The pairing of main ingredients has also come to emphasize the way of generating and overcoming.
So, it becomes possible to use relatively low-grade and weakened medicinal ingredients to match the effects of great medicines from ancient times.
In simple terms, it is the wisdom of later generations to complement strength with weakness, resulting in the same destination by different paths.
