(Indicated for Bi syndrome. From *Suwen: Bilun* [Treatise on Bi Syndrome in the Yellow Emperor's Inner Canon])
The combination of Wind, Cold, and Dampness pathogens leads to Bi syndrome (obstruction syndrome). When Wind is predominant, it is called Xingbi (Wandering Bi), characterized by pain that wanders up and down, left and right without staying in one place, occurring wherever the pathogen moves.
Fangfeng Tang (Saposhnikovia Decoction) is indicated: It treats Wandering Bi, where pain wanders without a fixed location, accompanied by numbness and discomfort.
Ingredients: Fangfeng (Radix Saposhnikoviae), Gancao (Radix Glycyrrhizae), Danggui (Radix Angelicae Sinensis), Chi Fuling (Poria with Red Host, peeled), Xingren (Seed Armeniacae Amarum, peeled and stir-fried), Guizhi (Ramulus Cinnamomi, each 1 liang), Huangqin (Radix Scutellariae), Qinjiao (Rhizoma Gentianae Macrophyllae), Gegen (Radix Puerariae, each 3 qian), Mahuang (Herba Ephedrae, 0.5 liang, nodes removed).
Preparation: Grind the above herbs into powder. Take 5 qian per dose, combined with wine and water totaling 2 zhan, 3 Jujubes (Fructus Ziziphi Jujubae), and 5 slices of Ginger (Rhizoma Zingiberis Recens). Decoct until reduced to 1 zhan, filter out the dregs, and take warm.
(Indicated for Bi syndrome. From *Suwen: Bilun* [Treatise on Bi Syndrome in the Yellow Emperor's Inner Canon])
When Cold is predominant, it is called Tongbi (Painful Bi), which requires vigorous unblocking and circulation. Pain caused by Yin-Cold should be treated by warming and unblocking the meridians to achieve recovery.
Jiajian Fuling Tang (Modified Poria Decoction) is indicated: It treats Painful Bi, characterized by pain in the four limbs, stiffness and fatigue, and edema.
Ingredients: Chi Fuling (Poria with Red Host, peeled), Sangbaipi (Cortex Mori Radicis, each 2 liang), Fangfeng (Radix Saposhnikoviae), Guigui (Cortex Cinnamomi Cassiae), Chuanxiong (Rhizoma Chuanxiong), Shaoyao (Radix Paeoniae Alba), Mahuang (Herba Ephedrae, nodes removed, each 1.5 liang).
Preparation: Grind the above herbs into powder. Take 5 qian per dose, with 1 zhan of water and 1 Jujube. Decoct until reduced to 8 fen, filter out the dregs, and take warm.
After taking the medicine, consume ginger congee to induce sweating; when sweating occurs as the target, the effect is achieved.
(Indicated for Bi syndrome. From *Suwen: Bilun* [Treatise on Bi Syndrome in the Yellow Emperor's Inner Canon])
When Dampness is predominant, it is called Zhuobi (Fixed Bi). Due to excessive dampness and water qi from wet environments, the body feels heavy and fixed, not moving away, often accompanied by profuse sweating and moisture.
Fuling Chuanxiong Tang (Poria and Chuanxiong Decoction) is indicated: It treats Fixed Bi, where pathogens remain lodged and do not depart, causing numbness in the four limbs, spasms, and edema.
Ingredients: Chi Fuling (Poria with Red Host), Sangbaipi (Cortex Mori Radicis), Fangfeng (Radix Saposhnikoviae), Guigui (Cortex Cinnamomi Cassiae), Chuanxiong (Rhizoma Chuanxiong), Mahuang (Herba Ephedrae), Shaoyao (Radix Paeoniae Alba), Danggui (Radix Angelicae Sinensis), Gancao (Radix Glycyrrhizae, honey-fried, equal parts).
Preparation: Grind the above herbs into powder. Take 2 qian per dose, with 2 zhan of water and 3 Jujubes. Decoct together until reduced to 1 zhan, filter out the dregs, and take warm on an empty stomach.
If sweating is desired, consume congee to assist.
(Indicated for Bi syndrome. From *Lingshu: Zhoubi* [Weekly Bi in the Spiritual Pivot])
The *Huangdi Zhenjing* (Yellow Emperor's Acupuncture Classic) states: The pathogen resides within the blood vessels, moving up and down. Originally fixed Bi pain now spreads throughout the whole body, hence the name "Zhoubi" (General/Weekly Bi).
Dadou San (Soja Seed Powder) is indicated: It treats Zhoubi, where pathogens lodge in the five Zang organs causing stagnation, and accumulate in the Stomach. It benefits Qi, expels toxins, moistens skin and hair, and tonifies Kidney Qi.
Ingredients: Dadou (Soja Seed, 1 jin, stir-fried until fragrant and cooked).
Preparation: Grind the above herb into powder. Take half a qian per dose, mixed with warm wine, taken on an empty stomach. The dose can be gradually increased to 1 qian, taken three times daily.
