这是治疗平素脾约之人又感受外邪，预防燥结的方法。方中用火麻仁和杏仁来润肠燥，芍药来滋养阴血，枳实和大黄来泻实热，厚朴来破滞气。但是必须是因为外邪入里化热才使用此方，否则不合规矩。后世以此方一概治疗老人津枯血燥导致的便秘，只图一时的通便，不顾及更伤真气，难道不是加速招致祸患吗？

This formula treats individuals prone to "Pi Yue" (Spleen Constraint) who contract external pathogens, serving as a preventive measure against dryness and constipation. The formula uses Huomaren and Xingren to moisten intestinal dryness, Shaoyao to nourish yin blood, Zhishi and Dahuang to purge excess heat, and Houpo to break up stagnant qi. However, it must only be used when external pathogens have transformed into heat internally; otherwise, it is inappropriate. Later generations used this formula indiscriminately to treat constipation in the elderly due to fluid depletion and blood dryness, seeking only temporary relief without regard for further damaging true qi, thereby hastening adverse consequences.
