| Cang Zhu | ||

Traditional Indications
The source associates it with Spleen and Kidney insufficiency following depletion, with emaciation, weakness, and a dull greenish-yellow complexion. It also records use in long-standing hemorrhoidal disorders linked in the text to blood deficiency, failure of qi to contain blood, and downward movement of damp-heat.
Preparation & Administration
Cang Zhu is soaked in oil; the photographed text does not state its quantity. Shu Di Huang is listed at one jin and Wu Wei Zi at half a jin; these historical jin amounts are retained without gram conversion. Gan Jiang varies by season: one liang in spring and winter (approximately 37.5 g), seven qian in autumn (approximately 26.25 g), and five qian in summer (approximately 18.75 g). Jujube flesh is used to form pills, taken with rice water or wine.
Formula Rationale
The commentary assigns Cang Zhu as chief, Shu Di Huang as deputy, Wu Wei Zi as assistant, and Gan Jiang as envoy. It describes the combination as addressing deficiency of both the Spleen and Kidneys while removing damp accumulation from the Spleen and relieving dryness in the Kidneys. The compact prescription is contrasted with later, more complicated dual-tonification formulas.
