Integrating chemical similarity and bioequivalence: an overall evaluation of the quality consistency of traditional decoction and dispensing granule decoction of Amomum villosum

Objective This study aims to investigate the quality consistency between traditional decoction (TD) of Amomum villosum and its dispensing granule decoction (DGD). Fifteen batches of TD and nine batches of dispensing granules (manufactured by A, B, and C) were prepared and evaluated for their consistency.
