Treats Bi syndrome (Obstruction Syndrome) caused by Wind-Cold-Dampness, manifesting as numbness and insensitivity of the limbs.
Chuanwu Tou (Radix Aconiti Lateralis Preparata, raw ground into fine powder).
For each dose, take half a bowl of well-cooked white rice, add four qian of the medicinal powder, and simmer slowly with the rice until it forms a thin porridge; it must not be thick. Add approximately one tea-foot amount of fresh ginger juice and three large spoons of white honey, stir evenly. It is best to drink this warm on an empty stomach. If the condition is due to Dampness invasion, add two qian of Coicis Semen Powder (Yiyiren), increase the rice quantity to one full bowl, cook and consume the porridge. This greatly treats inability to move the hands, feet, and limbs, as well as heaviness and pain preventing lifting. Those with these symptoms should take this in advance for prevention. Zuo Shi stated: "Excessive Wind leads to diseases of the extremities." The term "Four Extremities" refers to the four limbs. The Spleen governs the four limbs; when Wind pathogen invades the Liver, it overacts upon the Spleen. Since the Spleen is controlled by the Liver, the disease manifests in the extremities. The Qi of grain guides the Wind-Warm medicines directly into the Spleen Meridian, thus calming the limbs. This decoction is extremely effective; I often prepare this formula to give to others, and those who take it show good efficacy.

Treats Bi syndrome caused by Wind-Cold-Dampness, characterized by heavy and painful bones and tendons, wandering pain like stabbing, and weakness in the waist and legs.
Caowu (Four liang, skin and tip removed, salt-fried until smoke appears) Nanxing (Used raw) Dilong (Earth removed, fried) Poguozhi (Fried) Wulingzhi (Ground) Jingmo.
Grind all above into fine powder. Use vinegar-boiled paste to make pills, sized like Sophora japonica seeds. Take ten pills per dose, delivered with warm wine, gradually increasing the number of pills taken.

Treats Bi syndrome formed by Wind-Cold-Dampness lodging in Ying and Wei (Nutritive and Defensive levels), causing heavy and insensitive feet, painful weakness, dull pain under the soles, inability to step or flex/extend joints, stiffness and tension in the neck and back, arm weakness, tinnitus like cicadas, dizziness and vertigo, as well as various Hong Kong Jiao (Gout/Lower limb disorders), and difficulty walking.

Treats Bi syndrome where Wind-Cold-Dampness remains in the sinews and vessels, causing spasms and inability to turn or lie sideways; also treats Hong Kong Jiao.
Chuanwu Xixin Chuanjiao Baishyaoyao Fuzi Qinjiao Guigui Gancao (Each above 7 fen) Fangfeng Jiangjiang Danggui Baifurong (Each above 1 liang) Duohuo (1 liang 3 qian 5 fen).
Cut the above herbs. For each dose, take three qian, add one dan of water and two jujubes, decoct together until reduced to eight parts. Remove the dregs and take on an empty stomach. If there is excessive Heat-Toxin, taking more doses is also beneficial. For any stroke (Zhong Feng), using formulas such as Xuming Tang, Paifeng Tang, Fengyin Tang, Zhuli Tang, as well as Shenjing Dan and Yinyu Jiu, combined with moxibustion, will invariably lead to recovery. However, this disease accumulates over a long period and cannot be cured in a day; it requires large doses administered over a long time to achieve effect. The *Book of Tang* records that Empress Dowager Wang suffered from stroke, losing her voice and remaining silent. The physician steamed several hu of Huangqin (Scutellariae Radix) to fumigate her, resulting in recovery. These are all similar cases. Nowadays, people take only three or five cups of medicine and demand immediate results, blaming the doctor for being too slow; this is too hasty. Mencius said: "For a seven-year illness, seek three-year-old mugwort"; only through time does one understand this principle.
