（宋开宝）
【气味】辛大温，无毒。
【主治】主五劳七伤，风虚冷，骨髓伤败，肾冷精流，及妇人血气坠胎。
【核】曰∶补骨脂，即婆固脂，俗讹为破故纸者是也。出波斯国，及岭南诸州。今岭外
山间亦有之。茎高三四尺，叶尖小似薄荷，花色微紫，实似麻粒，圆扁而黑，宜九月采。
修事，酒浸一宿，洒出，再用东流水浸三日夜，蒸之，从巳至申，日干用。
【 】曰∶骨者形之一，肾之合也。盖形之所繇生，必先骨髓始，次及筋肉血脉皮毛曰
五形，即藏之所繇生，亦必先肾之肝，肝之脾，脾之心，心之肺曰五脏。脏藏神，形载气也。
肝者筋之合；脾者肉之合；血脉者心之合；皮毛者肺之合。合则神与藏俱，气与形俱矣。第
肾独有两，左曰水，右曰命门火；水即髓之源，火即生之本。本于阴阳，其气五藏五形，皆
通乎生气。失其所，则折寿而不彰，此寿命之本也。固色黑从肾，宜归于左；辛温从火，又
当偏向于右矣。是以两藏咸交，驱水火之精气，补裨骨髓。髓者，骨之脂也。复从骨髓，淫
气于骨，散精于肾，次第森荣，互为变化，则凡五脏化薄，致五形离决，而为劳为伤；五形
化薄，致五气消亡，而为极为痹，仍可使之次第森荣，互为变化。所谓骨气以精，谨道如法，
长有天命。
【宋开宝】
【气味】味辛，性大温，无毒。
【主治】主要治疗五劳七伤，风虚冷证，骨髓损伤败坏，肾冷精液滑脱，以及妇人因血气下坠导致的胎动不安或流产。
【核】曰：补骨脂，就是婆固脂，俗称为破故纸的就是它。产于波斯国，以及岭南各州。现在岭外山间也有生长。茎高三四尺，叶尖小像薄荷，花色微紫，果实像麻粒，圆扁且黑色，适宜在九月采收。
炮制方法：用酒浸泡一夜，取出沥干，再用东流水浸泡三昼夜，蒸制，从巳时到申时，晒干后使用。
【 】曰：骨是形体的一部分，与肾相合。大概形体的产生，必定先有骨髓，然后依次涉及筋肉、血脉、皮毛，这叫做“五形”；也就是脏腑的产生，也必定先从肾传至肝，肝传至脾，脾传至心，心传至肺，这叫做“五脏”。脏藏神，形体承载气。肝与筋相合；脾与肉相合；血脉与心相合；皮毛与肺相合。相合则神与脏共存，气与形体俱在。只是肾唯独有两个，左边叫水，右边叫命门火；水即是髓的源头，火即是生命的根本。基于阴阳，其气贯通五脏和五形，都通于生气。如果失去了其所依存的平衡，就会折损寿命而不显赫，这是寿命的根本所在。因为色黑归属于肾，适宜归于左（水）；味辛性温归属于火，又应当偏向于右（命门火）。因此两肾交济，驱策水火之精气，补益裨助骨髓。髓，是骨的油脂。再从骨髓，将气散布于骨，将精散入于肾，次第繁盛荣茂，互为变化，那么凡是五脏化生薄弱，导致五形分离决裂，从而成为劳证或伤证；五形化生薄弱，导致五气消亡，从而成为极度虚弱或痹证，仍然可以使之次第繁盛荣茂，互为变化。这就是所说的“骨气以精，谨道如法”，就能长久享有天命。
[Song Kai Bao]
[Aroma and Flavor] Pungent, greatly warm, non-toxic.
[Indications] Primarily treats five exhaustions and seven injuries (chronic debilitating conditions), wind-deficiency cold syndromes, damage and degeneration of bone marrow, kidney-cold with seminal emission, and in women, fetal restlessness or miscarriage caused by sinking of blood and qi.
[Analysis] It is stated: Bu Gu Zhi (Psoralea Fructus) is the same as Po Gu Zhi, commonly mispronounced as Po Gu Zhi (Broken Old Paper). It originates from Persia and various prefectures in Lingnan. It is also found in the mountains beyond Lingnan today. The stem is three to four chi high; the leaves are pointed and small, resembling mint; the flower color is slightly purple; the fruit resembles hemp seeds, being round, flat, and black. It is suitable for harvesting in the ninth lunar month.
Processing method: Soak in wine for one night, drain, then soak in flowing water from the east for three days and nights. Steam it from Si hour (9-11 AM) to Shen hour (3-5 PM), then dry in the sun for use.
It is stated: Bone is a part of the physical form, corresponding to the Kidney. Generally, the generation of form must begin with bone marrow, subsequently extending to sinews, vessels/blood, and skin/hair, which are called the "Five Forms"; similarly, the generation of Zang organs must begin with the Kidney transmitting to the Liver, the Liver to the Spleen, the Spleen to the Heart, and the Heart to the Lung, which are called the "Five Zang". The Zang organs store the Spirit (Shen), while the form carries the Qi. The Liver corresponds to sinews; the Spleen corresponds to flesh; vessels/blood correspond to the Heart; skin/hair correspond to the Lung. Correspondence implies that Spirit resides with the Zang, and Qi resides with the form. However, the Kidneys are unique in having two: the left is Water, and the right is the Fire of the Gate of Vitality (Ming Men); Water is the source of marrow, and Fire is the root of life. Based on Yin and Yang, their Qi connects through the Five Zang and Five Forms, all communicating with the vitalizing Qi. If this balance is lost, lifespan is shortened and not manifested; this is the root of longevity. Since black color belongs to the Kidney, it should be associated with the left (Water); since pungent and warm flavors belong to Fire, they should lean towards the right (Gate of Vitality Fire). Thus, the two Kidneys interact, driving the essence and Qi of Water and Fire to supplement and benefit the bone marrow. Marrow is the fat of the bone. From the bone marrow, Qi is disseminated into the bones, and Essence is scattered into the Kidneys. In an orderly manner, they flourish and transform into each other. Then, even if the transformation of the Five Zang becomes weak, leading to the separation of the Five Forms and resulting in exhaustion or injury syndromes; or if the transformation of the Five Forms becomes weak, leading to the extinction of the Five Qi and resulting in extreme deficiency or Bi (obstruction) syndromes, they can still be made to flourish in order and transform into each other. This is what is meant by "Bone Qi becomes refined, adhering strictly to the Dao and methods," thereby allowing one to long enjoy their heavenly mandate.
