[Collected Annotations] Cheng Wuji stated: "Yue" (restriction) refers to binding or constraining. The Classic of Internal Medicine states: When food and drink enter the stomach, their essence floats and overflows, moving upward to the spleen. The spleen scatters the essence, sending it upward to return to the lungs, which regulate the water passages and transport it downward to the bladder. Water essence is distributed throughout the body, and the five meridians function in parallel. Currently, the stomach qi is strong while the spleen qi is weak, constraining the body fluids so they cannot distribute throughout the body but only flow to the bladder. This results in frequent urination and hard stools, hence it is called "Pi Yue" (Spleen Restriction). Hemp seed is sweet, neutral, and moistening; apricot kernel is sweet, warm, and moistening. The Classic states: The spleen desires relaxation; one should urgently consume sweet substances to relax it. Materia Medica states: Moistening agents can remove dryness. Therefore, hemp seed is used as the sovereign herb, and apricot kernel as the minister herb. Immature bitter orange breaks up stagnation, and magnolia bark eliminates fullness, so they serve as assistant herbs. White peony root harmonizes the middle jiao, and rhubarb promotes purgation, so they serve as courier herbs. Zhu Zhenheng said: Since it is termed Spleen Restriction, if blood is depleted and fire flares consuming fluids, the principle should be to nourish yin and descend fire, allowing fluids to regenerate naturally; why would there be constipation? This formula is only suitable for cases with extreme heat and robust constitution. For those with mild heat and deficiency, using this formula will exacerbate the suffering of dryness and depletion.

Indicated for blood stasis knotting in the chest, causing pain so severe that the area cannot be touched by hand, or blood accumulation in the middle jiao presenting with alternating chills and fever, chest fullness, rinsing the mouth without desire to swallow, forgetfulness, and coma-like delirium. This formula treats retained bad blood in the meridians and regulates menstruation.
