Psoralea Fruit

Traditional Use

Primary Actions

• Warms Kidney yang and restores lower-burner fire - Po Gu Zhi is an older-name record for the same classic herb used in cold weakness, impotence, infertility, and sore low back.
• Secures essence and shrinks urination - it is widely used for spermatorrhea, enuresis, urinary frequency, and other leakage patterns from deficient Kidneys.
• Warms the Spleen and checks chronic dawn diarrhea - it is especially useful when cold deficiency drives early-morning stool with abdominal chill and fatigue.
• Assists the Kidney in grasping qi - traditional combinations use it for chronic wheezing or dyspnea when deficiency prevents the lower burner from receiving breath.

Secondary Actions

• Po Gu Zhi is the older or alternate name commonly written with the character 破, while Bu Gu Zhi is the dominant modern naming form for the same medicinal fruit.
• Like the main Bu Gu Zhi record, this herb also appears in topical vitiligo practice because the source plant contains photosensitizing furocoumarins.

Classic Formulas

• Si Shen Wan - classic dawn-diarrhea formula using Po Gu Zhi or Bu Gu Zhi naming interchangeably in many lineages.
• Qing E Wan and related lumbar-tonic formulas rely on Po Gu Zhi for warming the Kidneys and strengthening the low back.
• Chronic wheezing formulas combine it with Ren Shen, Hu Tao Rou, or Chen Xiang when the Kidney cannot grasp qi.

Classical References

• TCMWiki lists Po Gu Zhi as an accepted naming form and records its warm, sweet-bitter-astringent action on the Kidney, Spleen, and Lung.
• Traditional herbology treats Po Gu Zhi and Bu Gu Zhi as the same classic psoralea fruit rather than as separate medicinals.
