[Formula] Shunfeng Yunqi San (Pill)

Indicated for hemiplegia and deviation of the mouth and eyes caused by wind-stroke. Hemiplegia is also known as pianku (hemiplegic paralysis). The *Huangdi Neijing* states: If the stomach pulse is deep, forceful yet choppy, or superficially forceful and large; and if the heart pulse is small, firm, and rapid, these pulse patterns all belong to pianku. In men, onset often occurs on the left side; in women, on the right side. If the patient does not suffer from aphasia (yin) and the tongue moves flexibly, the condition is treatable. This is because the Heart is the root of the development of Shen-ji (spiritual mechanism), and the Stomach is the branch/source of nourishment from food and fluids. When root and branch are harmonious, the Zongqi (Gathering Qi) gathered at the Danzhong (Conception Vessel 17) and Qihai (Conception Vessel 6) acupoints will be abundant and overflow, distributing to the four zang organs and the Triple Burner, ensuring comprehensive coverage throughout the upper, lower, interior, and exterior. If root and branch are discordant, Zongqi becomes deficient and depleted. If its distribution fails to reach the meridians comprehensively, it results in pianku; if it fails to reach the five zang organs comprehensively, it results in aphasia. Deviation of the mouth and eyes occurs because the Foot-Yangming Stomach Meridian passes alongside the mouth and circles the lips. Cold causes tendon tension (spasm), while heat causes tendon flaccidity. Left-sided cold and right-sided heat result in left-sided tension and right-sided flaccidity; right-sided cold and left-sided heat result in right-sided tension and left-sided flaccidity. The Foot-Yangming Dryness-Metal governs... [text missing/corrupted].

[Composition] Baizhu (Atractylodis Rhizoma, 2 qian), Wuyao (Linderae Radix, 1.5 qian), Renshen (Ginseng Radix et Rhizoma), Tianma (Gastrodiae Rhizoma, 0.5 qian), Baizhi (Angelicae Dahuricae Radix), Suye (Perillae Folium), Mugua (Chaenomelis Fructus), Qingpi (Citri Reticulatae Pericarpium Viride), Gancao (Licorice Root, honey-fried).

This formula targets the Foot-Jueyin Liver Meridian and Foot-Yangming Stomach Meridian. Where evil qi gathers, righteous qi must be deficient. Pianku and physical deviation, whether on the left or right, occur because blood vessels do not circulate uniformly, and qi movement is uneven. By promoting qi circulation and tonifying qi, the qi becomes uniform; when qi is uniform, wind ceases. Mugua is used because it can drain Wood within Earth, harmonize Ying (Nutrient) and Wei (Defensive) qi, and extend tendons. (Dai Fu'an stated: The method for treating wind diseases should prioritize regulating qi upon initial onset, and promoting blood circulation once the disease has persisted. If qi is not regulated, one should not hastily use Wu Tou (Aconiti Lateralis Radix Preparata) and Fu Zi (Aconiti Radix Preparata); if blood is not circulated, one should not hastily use Qiang Huo (Notopterygii Rhizoma et Radix) and Fang Feng (Saposhnikoviae Radix)...).

[Physician Zhang Yong's Formula] Indicated for body deviation, speech impediment (jianse), limb flaccidity, and bone pain due to wind-stroke; as well as migratory pain due to wind-bi, numbness of the ten fingers, and various sores caused by wind-dampness affecting the Liver and Kidney.

Deviation of the mouth and eyes with speech difficulty indicates wind pathogen invading the meridians; limb flaccidity and bone pain indicate wind combined with dampness; wind-bi swelling and pain indicate damp-heat flowing and accumulating, commonly referred to in secular terms as "liuhuo" (flowing fire)...

[Herb Description] Herb. Best harvested on the fifth day of the fifth lunar month, the seventh day of the seventh lunar month, and the ninth day of the ninth lunar month. Quantity is unrestricted. Remove coarse stems, retaining branches, leaves, flowers, and fruits. Mix with wine, steam, and dry nine times, then form into honey pills. It tastes bitter and pungent, has a cold nature, and possesses an odor. It must be steamed and dried nine times; adding wine and honey resolves the yin-turbid nature of its bitter-cold properties...

This formula targets the Foot-Shaoyin Kidney Meridian and Foot-Jueyin Liver Meridian. The herb can dispel wind and scatter dampness, and move qi in the Large Intestine. Combined with wine-steaming and honey-pilling, its aroma and flavor become clear and harmonious, thus enabling it to tonify the Liver and moisten the Kidney, benefit qi, and strengthen tendons (when dampness is removed, tendons become strong). However, wind-dispelling herbs are ultimately drying. If wind-bi arises from deficiency of both Spleen and Kidney with insufficient yin-blood, rather than from wind-dampness, this formula is contraindicated. (Tang Chengne submitted a memorial, and Song Dynasty physician Zhang Yong also submitted a memorial stating: This herb features gold edges and silver lines, pale stems with purple... nodes and leaves are opposite each other, resembling Cang Er (Xanthii Fructus). I have taken it hundreds to thousands of times, resulting in black hair and beard, and light, agile sinews and bones, with numerous efficacious outcomes.
