(Primarily treats disorders of the four limbs. Originates from *Suwen: Yin-Yang Bie Lun* [Treatise on Differentiating Yin and Yang in the Yellow Emperor's Inner Classic].)
Swelling of the four limbs is caused by excessive heat in the four limbs. The four limbs are considered the root of all Yang meridians; when Yang Qi (vital energy associated with warmth and activity) becomes knotted or stagnant, it cannot circulate freely through the Yin and Yang meridians. Due to this obstruction, it remains and accumulates within the body.
Xijiao Tang (Rhinoceros Horn Decoction) is indicated for Jieyang Syndrome (Yang Qi stagnation), characterized by swelling and fullness of the four limbs, persistent accumulation of heat, or toxic pathogens attacking and penetrating, leading to constipation and difficult defecation.
Rhinoceros Horn (shavings) Xuan Shen (Scrophulariae Radix) Lian Qiao (Forsythiae Fructus) Chai Hu (Bupleuri Radix, stems removed. Each 0.5 liang) Sheng Ma (Cimicifugae Rhizoma) Mu Tong (Akebiae Caulis. Each 3 qian) Chen Xiang (Aquilariae Lignum Resinatum, sliced)
She Gan (Belamcandae Rhizoma, hairs removed) Gan Cao (Glycyrrhizae Radix et Rhizoma, honey-fried. Each 1 fen) Mang Xiao (Natrii Sulfas) Mai Men Dong (Ophiopogonis Radix, hearts removed. Each 1 liang)
Grind the above ingredients into a fine powder. Take 3 qian per dose, add one large cup of water, and decoct together until only 8/10 remains. Strain the dregs and take warm before meals.
(Primarily treats abdominal pain. Originates from *Suwen: Wu Zang Sheng Cheng Lun* [Treatise on the Generation of the Five Viscera in the Yellow Emperor's Inner Classic].)
The pulse is large yet deficient, indicating accumulated Qi in the abdomen that is hidden and difficult to detect. Yin Qi is stagnant, causing Spleen deficiency and coldness in the limbs and genitals; this is a manifestation of Qi reversal (Jue).
Jiajian Wuzhuyu Tang (Modified Evodia Decoction) is indicated for Jueshan Syndrome (Cold-type Hernia), characterized by cold pain in the abdomen, upward reversal of accumulated Qi, and resulting coldness in the limbs and genital region.
Wu Zhu Yu (Evodiae Fructus, 2 liang, washed with hot water and stir-fried) Chuan Wu Tou (Aconiti Radix, skin removed and processed) Xi Xin (Asari Radix et Rhizoma, stems removed. Each 3 liang) Liang Jiang (Alpiniae Officinarum Rhizoma) Dang Gui (Angelicae Sinensis Radix)
Gan Jiang (Zingiberis Rhizoma, processed) Guan Gui (Cinnamomi Cortex. Each 1 liang)
Grind the above ingredients into a fine powder. Take 2 qian per dose, add one cup of water, and decoct together until only 7/10 remains. Strain the dregs and take warm. Administer three times daily.
(Primarily treats hematochezia/bloody stool. Originates from *Suwen: Yin-Yang Bie Lun* [Treatise on Differentiating Yin and Yang in the Yellow Emperor's Inner Classic].)
In Jieyin Syndrome (Yin Qi stagnation), the first episode of bleeding results in the loss of one sheng of blood, the second episode two sheng, and the third episode three sheng. Because Yin Qi is internally knotted, Qi and Blood cannot circulate smoothly. Without proper control by the vital substances, blood seeps into the lower intestines, causing the volume of bleeding to gradually increase.
Diyu Tang (Sanguisorbae Radix Decoction) is indicated for Jieyin Syndrome, characterized by continuous lower bleeding that gradually becomes severe, accompanied by unceasing abdominal pain.
Di Yu (Sanguisorbae Radix, 4 liang) Gan Cao (Glycyrrhizae Radix et Rhizoma, 3 liang, half honey-fried, half raw) Suo Sha Ren (Amomi Fructus Rotundus, 7 capsules; dosage may be increased per dose for better effect)
Grind the above ingredients into a fine powder. Take 5 qian per dose, add three cups of water and Suo Sha Ren, and decoct together until only half remains. Strain the dregs and take warm.
