(Administered with Ginseng Decoction. If Ginseng is sparingly used, Longan Fruit Decoction is also good.)
Gouqi (Cortex Lycii Fructus, 1 jin) Bugu Zhi (Fructus Psoraleae, 8 liang) Baizhu (Rhizoma Atractylodis Macrocephalae, 4 liang) Hujiao (Piperis Fructus, 2 liang). Steam for a long time, sun-dry; extreme purity is desirable.

"Chun Yang" (Spring Sun) refers to the administration of Wood Qi (Liver Qi). "Hui Ling" means returning its generating command. Trees flourish when they receive Water and wither when they lose it. Qi being full leads to flourishing, while Blood loss leads to withering. Flourishing attracts Wind Pathogen, while withering invites Fire Pathogen. Its movement is like thunder and lightning, its eruption like wind and rain, entering and exiting alone, unpreventable. Among the Five Viscera, none is harder to balance than the Liver. Therefore, diseases belonging to the Liver are numerous, and methods for treating the Liver are extremely broad. If blood depletion and severe diarrhea occur, resulting in Yin Storm Blindness (sudden blindness), this is caused by extreme deficiency of the Spleen, Kidney, and Liver, leading to the sinking of Yang Qi within the viscera. In this formula, Gouqi is sweet in taste and moist in nature, nourishing the Blood. Bugu Zhi is black in color and has a fermented odor, warming the Kidney Water. Water generates it, Blood nourishes it, so that Wood flourishes without withering. The pungent heat of Hujiao returns Yang, while the pungent warmth of Baizhu tonifies Earth (Spleen/Stomach). When Yang returns, flowers and leaves naturally flourish; when Earth is thick, roots and trunks become strong. The use of Renshen (Ginseng) is because vital Qi is abundant and reaches everywhere. As stated, if one breath does not move, the mechanism is exhausted; if even a tiny bit is not continued, heaven and earth are separated. This allows the Wood command to return to spring, and Earth, Fire, Metal, and Water generate each other in sequence. Some who do not understand this principle, seeing blood exhaustion, may advocate using pure Yin Siwu Tang (Four Substance Decoction), fearing it will cause the earth to be blocked and all things to fail to grow. Estimating essence consumption, they may advance Liuyi Dihuang Wan (Six-Ingredient Pill with Rehmannia), inevitably causing mountains to swell and floods to rise, with water overflowing and Wood floating. Thus, it is said that Siwu Tang and Liuyi Dihuang Wan are sometimes prohibited from use, which covers such cases. I composed this pill, daring to correct the mistakes of modern people, truly supplementing what ancient formulas could not cover. Those of high wisdom, please instruct me.

Poem says: Gouqi, Baizhu, and Bugu Zhi, Renshen and Hujiao restore the Spring Command. Understand sudden blindness, sincerely seek and generously apply the response.

Ganjiang (Dried Ginger Rhizome) Fuzi (Prepared Aconite Root) Congbai (Scallion White) (Remove Congbai and add Gancao to form Sini Tang).
Shaoyin disease presents with diarrhea and sudden blindness; both hands have deep and soggy pulses. This formula governs.
The Shaoyin Kidney corresponds to the Winter command, governing the closure and storage of Heaven and Earth. When Cold Pathogen invades, the Yin channels are not secure, leading to diarrhea. Diarrhea causes Yang Qi to leak secretly, hence the pulse is deep and soggy, and blindness occurs. Therefore, Congbai is used to unblock Yang Qi, while Ganjiang and Fuzi disperse Yin Cold. When Cold disperses and Yang recovers, the blocked becomes unblocked, and the unblocked remains open. It can be named Baotong (White Connecting) based on the scallion.

I once treated a certain Mr. Jia. After administering this decoction, diarrhea did not stop, gradually leading to cold limbs, absence of pulse, dry retching, and hiccups. Someone cited the *Shanghan Lun* saying: This is Cold excess repelling Yang (Cold Pathogen is too severe, rejecting Yang Qi outward), unable to descend to Shaoyin, instead reversing chaotically upwards. One must add Human Urine and Pig Bile to guide it. Upon careful thought, sudden blindness is due to extreme Kidney Yang deficiency. Regretting the use of too much Congbai (which is too dispersing for the exterior), adding the extremely cold and bitter urine and bile would be kicking someone when they are down. So-called not dying from the disease, but dying from the medicine. Instead, I used Persimmon Calyx, Clove, and Dried Ginger, decocted strongly into a large cup. After swallowing, hiccups stopped immediately. Then administered Bawu Huisheng Yin (Eight-Ingredient Revival Decoction) for five or six doses. The body warmed, pulse resumed, and vision was restored. This shows that printed books require living reading by humans; how can printed formulas be used rigidly? Furthermore, Taiyin spontaneous diarrhea without thirst, Yin syndrome with deep pulse and body pain, as well as cold limbs with no diarrhea and absent pulse, use Sini Tang, taken cool after decoction. Wu Qian's commentary states: Taiyin governs water and grain, containing true Cold, hence spontaneous diarrhea without thirst. Yin syndrome refers to the Three Yin channels; since the disease is interior, the pulse is deep. Interior Cold causes blood vessels to coagulate and stagnate, unable to distribute to the hands and feet, hence body pain, cold limbs, absent pulse, and diarrhea. The Classic says: Cold rampant inside, treat with Sweet and Hot. Hence, use Roasted Licorice, Ginger, and Aconite to promote Yang Qi. Also, taking it cool: the Classic says treat Cold with Heat, administer hot remedies in a cool manner. Otherwise, for Daiyang syndrome (Floating Yang), it would increase upper dryness, causing bleeding from mouth, eyes, ears, and nose, which is severe. The difficulty of using medicines is thus.

Note: Ginger is pungent, warm, and non-toxic. Not only does it dispel Cold, but it also connects the Spirit and removes filth. Hence, sages do not eat food left overnight. Licorice is indeed thick, honest, peaceful, and harmonious, regulating both Cold and Heat; pharmacists call it the "Old Man of the State." Besides Licorice, Sini Tang contains only Aconite. Although Aconite's nature is more intense than Ginger, for Yin syndrome, cold limbs, spontaneous diarrhea, and absent pulse, using another intensely hot tonic, decocted and rapidly administered, is harmless. Why take it cool? Hegao annotated the *Neijing*, yet speaks so much. How many city physicians are truly enlightened? If one actually sees red face and bleeding from seven orifices, one would surely claim this is false Cold, caused by mistakenly investing Ginger and Aconite. One would definitely switch to Zhibai Siwu Tang or Liuyi Dihuang Wan, leading to death upon swallowing. Students discussing this should stand up and listen respectfully.

Poem says: After Shaoyin diarrhea, the pulse is deep and soggy; both eyes follow blindness, treated with Baotong. Baotong adds Ginger and Aconite to Scallion White; remove Scallion, add Licorice to form Sini. If Sini does not harmonize and the disease changes, warming the meridians nine times can be applied peacefully.
