Po Gu Zhi (Burmese Psoralea Fruit), also known as Bu Gu Zhi, has the effects of drying dampness and warming/tonifying the Fire of the Mingmen (Gate of Life).
It is acrid, bitter, and greatly warm in nature. It enters the Pericardium (Heart Protector) and Mingmen channels. It tonifies the Ministerial Fire to unblock the Sovereign Fire, warms the Dantian, strengthens the Primordial Yang, and reduces urination. (It can also treat enuresis.) It treats asthma and cough due to deficiency-cold. (It can grasp Qi and return it to the Kidney.) It also treats soreness and pain in the lower back and knees, coldness of the Kidney with seminal emission, and diarrhea due to fire deficiency. (This is because the decline of Mingmen Fire fails to steam and transform the Spleen and Stomach; Spleen-Stomach deficiency-cold leads to slow transportation, resulting in reduced appetite, abdominal distension, borborygmus, vomiting of saliva, and diarrhea. This is like a pot without fire underneath, where food cannot be cooked thoroughly; therefore, one must tonify the Mingmen Fire.)
[Formula] Wu Wei Zi (Schisandra Berry) 3 liang, Rou Dou Kou (Nutmeg) 2 liang, Wu Zhu Yu (Evodia Fruit) 1 liang, boiled with ginger and dates to form pills, named Si Shen Wan (Four Spirit Pill), treats dawn diarrhea.
Used for women's blood and Qi disorders. (Blood loss and Qi sinking in women are similar to coldness of the Kidney and seminal emission in men.)
Contraindications: Abortion. Contraindicated in cases of Yin deficiency with heat and constipation.
Origin and Characteristics: Those from Nanfan are reddish; those from Lingnan are greenish. Usage: Soaked in wine and steamed. Some are soaked in child's urine or milk, or stir-fried with salt water. It works well when combined with Hu Tao (Walnut) and Hu Ma (Sesame). It is incompatible with Gan Cao (Licorice Root). [Tang Dynasty Chancellor Zheng's Formula: Po Gu Zhi 10 liang, soaked in wine and steamed, ground into powder; Hu Tao Ren (Walnut Kernel) 20 liang, peeled and pounded into paste, mixed with honey to resemble maltose syrup. Take one large spoonful with wine every morning to treat deficiency-cold asthma/cough and soreness/pain in waist and legs. Avoid eating sheep blood and rapeseed greens. Adding Du Zhong (Eucommia Bark) creates Qing E Wan (Green Young Woman Pill). Han Feixia stated: Po Gu Zhi belongs to Fire, solidifying Primordial Yang; Hu Tao belongs to Wood, moistening dryness and nourishing Blood, embodying the wonderful interaction of Wood generating Fire.]
Yi Zhi Ren (Alpinia Oxyphylla Fruit) dries dampness and strengthens the Spleen, and tonifies the Qi of the Heart and Mingmen.
It is acrid and hot in nature. It primarily acts on the Spleen channel but also enters the Heart and Kidney channels. It governs both the Sovereign and Ministerial Fires, tonifying the insufficiency of Heart Qi and Mingmen. It can secure essence and consolidate Qi, and also resolve stagnation, allowing Qi to circulate freely. It warms the middle Jiao to promote appetite and controls salivation. (Coldness of the Stomach causes excessive salivation.) It reduces urination. (The Kidney and Bladder are exterior-interior related; Yi Zhi Ren is acrid-warm and secures the Kidney. Stir-fried with salt water, used in equal parts with Wu Yao (Lindera Root), boiled in wine with Shan Yao (Dioscorea Rhizome) paste to form pills, taken with salt water, named Suo Quan Wan (Bladder-Contracting Pill).) It treats external cold invading the Stomach, cold Qi causing abdominal pain, vomiting, and diarrhea, seminal emission, metrorrhagia, and leukorrhea.
Contraindications: Those with blood dryness and heat, specifically those with metrorrhagia, leukorrhea, or turbid discharge caused by heat, must not be mistakenly treated with this herb.
Origin and Characteristics: Originates from Lingnan. Shape resembles a jujube pit. Use the kernel. Stir-fry with salt water. (In cases of abdominal distension with sudden, incessant diarrhea unresponsive to other medicines, decoct Yi Zhi Ren strongly and drink it.)
