Cauti (Gardenia Trichotoma Fruit), one fen, processed by frying; Chixiaodou (Adzuki Bean), one fen.
The above two herbs are separately pounded and sifted into powder, then mixed together. Take one qianbi (a small measuring spoon) of the powder. Use Xiangchi (Prepared Soybean Fermented), one he, with seven he of hot water, boil until it resembles a thin porridge. Strain to remove the dregs, take the liquid, mix with the powder, and take warm in one dose. If vomiting does not occur, gradually increase the amount slightly until diarrhea or vomiting occurs, then stop.

After Han syndrome has undergone emesis and purgation followed by sweating, Yang deficiency leads to irritability, and the pulse is extremely faint. On the eighth or ninth day, epigastric fullness and hardness, pain in the hypochondrium, Qi rushing up to the throat, dizziness, and twitching of the meridians occur; if prolonged, this develops into flaccidity syndrome (Wei Bing).
Emesis, purgation, and subsequent sweating cause Yang deficiency and irritability, with an extremely faint pulse. By the eighth or ninth day, epigastric fullness and hardness and hypochondriac pain arise. This is due to the loss of Yang and the failure of the Spleen-Stomach Earth, causing Stomach Qi to rebel upward and obstruct the descending pathway of the Gallbladder Meridian. The Gallbladder Meridian originates from the stomach region and runs along the hypochondrium; when the meridian is congested, epigastric fullness and hypochondriac pain result. Obstruction at the stomach opening prevents Lung Qi from descending, causing Qi to rush up to the throat. Rebellion of Lung and Stomach Qi causes Yang Qi to float and rotate restlessly, leading to dizziness. Accumulation of turbid Qi without unblocking causes the meridians to be unable to contain the righteous Qi, resulting in twitching. Such conditions, if prolonged, lead to flaccidity syndrome. Generally, the Liver governs Ying Blood and controls the sinews; when blood is abundant, sinews are flexible, preventing flaccidity. If Jia Wood (Gallbladder) rebels upward and Ministerial Fire flares, Yi Wood (Liver) fails to descend, generating wind; Ying Blood becomes stagnant and sluggish, and Qi dynamics are impaired. Suppressed Wind-Wood causes tremors. Prolonged lack of nourishment to the meridians results in flaccidity disease. The *Su Wen* states that for treating flaccidity, one should exclusively focus on the Yangming channel. Yangming is the sea of the five Zang and six Fu organs, primarily moistening the Zong Jin (major tendons). Zong Jin binds the bones and facilitates joint movement. The Chong Mai (Penetrating Vessel) is the sea of the meridians, primarily infiltrating the muscle valleys, and merges with Yangming at the Zong Jin. Yin and Yang converge at the Zong Jin, meeting at Qichong (ST30), with Yangming as the leader, all connected to the Dai Mai (Belt Vessel) and linked to the Du Mai (Governing Vessel). Thus, Yangming deficiency leads to laxity of Zong Jin and inability of the Dai Mai to draw, resulting in foot flaccidity and inability to use them. When Yangming Qi descends, it transforms into Metal and Water; Metal and Water store Ministerial Fire, keeping it secure below to warm the Kidney and Liver, nourishing Wood Qi, so sinews remain light and agile without flaccidity. If Yangming fails to descend, Stomach Qi rebels, Gallbladder Qi rises, Fire leaks out, Water becomes cold, vital Qi withers, sinews lose nourishment, and flaccidity ensues.

In Taiyang disease, after medical sweating, fever and aversion to cold persist; subsequently, purgation is applied, leading to epigastric fullness. Both exterior and interior are deficient, and both Yin and Yang Qi are exhausted. Absence of Yang implies dominance of Yin. If moxibustion (burning needle) is added, chest irritability arises. A greenish-yellow complexion with skin twitching indicates difficulty in treatment; a slightly yellow complexion with warm hands and feet indicates ease of recovery.
In Taiyang disease, medical sweating causes simultaneous deficiency of Ying and Wei. Wei Qi sinking inward causes fever; Ying Blood constrained outward causes aversion to cold. Seeing that sweating did not resolve the condition, the physician applies purgation, causing Yang loss and Spleen-Stomach failure, resulting in epigastric knotting. Sweating depletes exterior Qi, purgation depletes interior Qi; both exterior and interior are deficient, and internal and external Qi are exhausted. Exterior and interior Yang are lost, leaving only solitary Yin. Adding burning needles to drain Heart and Lung Qi causes chest diaphragm irritability. A greenish-yellow face with skin twitching indicates Earth failure with Wood encroachment, wind movement, and meridian stagnation; this disease is difficult to treat. A slightly yellow, non-green face with warm, non-cold hands and feet indicates restoration of Earth Qi without Wood pathogenic influence, return of Yang to the four extremities rather than solitary Yin; this disease is easy to recover from.
