Use pig heart blood, dry it on a new tile by roasting, grind into fine powder, mix with Moschus (Musk), and form pills with wine paste the size of Sophora japonica seeds. Take seven pills per dose.
In *Boji Fang* (Universal Relief Formulas), it is named Wulong Dan (Black Dragon Pill), but the preparation method differs.
Chuanwu (Aconiti Radix, skin and tip removed, sliced, five taels) Wulingzhi (used raw, fresh, five taels)
Pulverize and sieve the above ingredients into fine powder, add a small amount of Borneolum Syntheticum (Borneol) and Moschus (Musk), mix with drops of water to form pills the size of bullet seeds. For each pill, those over fifty years old should divide it into four doses; for the elderly, divide into six doses. Soak in freshly squeezed ginger juice overnight until soft, then dissolve in a cup by hand, liquefy with mint wine, and add a small amount of Borneolum Syntheticum (Borneol) and Moschus (Musk) to the wine. When preparing this medicine, choose the third day of the third lunar month, the fifth day of the fifth lunar month, the sixth day of the sixth lunar month, or a Chen day. Do not let pregnant women, chickens, or dogs see it. Place rice straw on a rice sieve first, spread the pills on top, and dry them naturally in a ventilated place. Store them without allowing them to be damaged by heat or moisture; hang them in a gauze bag. After handling this medicine, do not rub your eyes with your hands. When taking this medicine, avoid hot food and drinks for two shichen (four hours). It treats stroke in men and women, hemiplegia, dysarthria, gait abnormalities, cases where other medicines have failed, long-standing crural deformity (crux equinus), and an-feng (hidden wind), with no case that cannot be cured. Taking it for thirty days removes the root cause. Children should divide each pill into eight doses. My fifteenth brother suffered from an-feng for over ten years; after obtaining this medicine, he recovered.
Shehuang (Reptilis Corium, quantity不限, roast with rice vinegar and quench seven times)
Grind the above into powder. Take two qian per dose, swallow with warm wine. Recovery occurs after several doses; it is also effective for chronic cases.

Tiannanxing (Arisaematis Rhizoma, two taels, large ones: dig a pit more than one chi deep, heat with fire until red, remove fire, place Arisaematis Rhizoma inside, immediately pour rice vinegar over it, one tael, separately ground)
Mix evenly, form pills with pig heart blood the size of Sophora japonica seeds. Take fifteen pills per dose, swallow with Ginseng Radix et Rhizoma or Ophiopogonis Tuber decoction, take before going to bed.
