Concentrated granules pèi fāng kē lì · 配方颗粒

The modern default in most overseas clinics: single herbs extracted, dried into granules, and dispensed as a measured mixture to dissolve in hot water. It removed the need to boil herbs at home, which was the single biggest practical barrier for patients.

The trade-offs are that granular products vary between manufacturers, and quality-control failures — heavy metals, pesticides, adulteration — have been documented across the supply chain. Ask suppliers about testing.
