The Effusion of Wu Shi San (五石散):Consuming and Abusing the Powder in Medieval China

Abstract: Wu Shi San (五石散 Five-Mineral Powder) is a powdered medicinal preparation constituted from mineral constituents. Its ingestion became a defining obsession among China’s elite from the third to the ninth centuries. Drawing upon the framework of traditional Chinese materia medica, this study critically surveys a diverse range of primary sources, such as official histories, anecdotal accounts, medical texts, and religious canons, to examine the effusion of the powder (散发 San Fa ) and the ingestion protocols designed to maximize its positive effects. It reveals that the release of its medical power was perceived as a complex physiological transformation; users employed specific dietary adjustments, warm wine consumption, and physical exercise to guide the internal flow, aiming to achieve physical vigor, sensory acuity, and enhanced libido. This paper argues that the pursuit of these effects led to a systematic abuse of effusion, transforming it into a social performance: while elites utilized it to signal status, commoners faked symptoms to mimic such prestige, and certain noblemen feigned the dispersal process to evade political obligations. Ultimately, this study demonstrates that the ingestion of the powder was not merely a physiological dependence but a socially-conditioned addiction. This research elucidates the intricate interplay between medical practices and identity formation, thereby revealing the profound integration of medicine, politics, and culture. Specifically, it illuminates the cultural implications and the conscious and unconscious prejudices embedded within the medical practices of Medieval China.
