Treat Yin-cold syndrome with deep pulse, cold limbs (Jue-leng), vomiting, and diarrhea.
Fuzi (Raw, one piece) Ganjiang (Dried Ginger, five qian) Gancao (Licorice Root, six qian)
Decoct the above three herbs in water, divide into two doses, and take warm. For robust individuals, a large Fuzi (one piece) and Ganjiang (one liang) may be used.
Si Ni Jia Ren Shen Tang (Four Reversal Decoction plus Ginseng, from *Shanghan Lun - Yu Han*): Treats aversion to cold, faint pulse, and diarrhea.
Add Renshen (Ginseng Root) three qian to one liang to Si Ni Tang.
Fu Ling Si Ni Tang (Poria Four Reversal Decoction, from *Shanghan Lun - Yu Han*): Treats restlessness (Fan-zao) persisting after sweating or purging therapies have failed to resolve the disease.
Add Renshen (Ginseng Root) three qian to one liang, and Fuling (Poria, three qian to one liang) six qian to Si Ni Tang.
Tong Mai Si Ni Tang (Pulse-Rescuing Four Reversal Decoction, from *Shanghan Lun - Yu Han*): Treats Shaoyin disease with diarrhea of undigested food, interior cold with exterior heat (True Cold, False Heat).
Double the dosage of Ganjiang (Dried Ginger) in Si Ni Tang.
Tong Mai Si Ni Jia Zhu Dan Zhi Tang (Pulse-Rescuing Four Reversal Decoction plus Pig Bile, from *Shanghan Lun - Yu Han*): Treats cases where vomiting and diarrhea have ceased but limb spasms persist, and the pulse is faint and nearly imperceptible.
Double Ganjiang (Dried Ginger) in Si Ni Tang and add Zhuyezhi (Pig Bile).
Bai Tong Tang (White Pass Decoction, from *Shanghan Lun - Yu Han*): Treats Shaoyin disease with diarrhea and faint pulse.
Remove Gancao (Licorice Root) from Si Ni Tang. The original formula uses Ganjiang (Dried Ginger) and Fuzi (Aconite Root) three qian each, plus Congbai (Scallion White) four stalks.
Bai Tong Jia Zhu Dan Zhi Tang (White Pass Decoction plus Pig Bile, from *Shanghan Lun - Yu Han*): Treats Shaoyin disease with diarrhea, cold limbs, absence of pulse, dry heaving, and irritability.
Remove Gancao (Licorice Root) from Si Ni Tang. Use Ganjiang (Dried Ginger) and Fuzi (Aconite Root) three qian each, add Congbai (Scallion White) four stalks, Ren Niao (Human Urine) five he, and Zhuyezhi (Pig Bile) one he.
Ganjiang Fuzi Tang (Dried Ginger and Aconite Decoction, from *Shanghan Lun*, also known as Jiang Fu Tang): Treats Shaoyin disease with daytime restlessness.
Remove Gancao (Licorice Root) from Si Ni Tang. Si Ni Tang utilizes the acrid-hot nature of Ganjiang (Dried Ginger) and Fuzi (Aconite Root) to restore Yang Qi, while Gancao is used to moderate their intensity, allowing them to act gradually to reach the extremities. This formula is specifically designed for conditions presenting initially with cold limbs, deep pulse, and no fever. Even in Taiyin disease with spontaneous diarrhea and abdominal pain, or Jueyin disease with diarrhea and limb spasms, the principle remains the same, as pathogenic factors in Jueyin invariably enter via Shaoyin. This method applies not only to the Three Yin meridians but also to Taiyang disease presenting with headache, fever, and deep pulse; one must first rescue the interior Yang before releasing the exterior, which aligns with proper treatment principles. For Shaoyin disease with daytime restlessness, Ganjiang Fuzi Tang removes Gancao from Si Ni Tang to use only these two herbs to rapidly dispel Yin-cold turbidity, similar in intent to Bai Tong Tang. Considering this, if Si Ni Tang is applicable to Taiyang, surely Bai Tong Tang has relevance to Jueyin? Although the Jueyin chapter mentions Tong Mai Si Ni Tang but not Bai Tong Tang, a detailed comparison shows they differ by only one herb: Tong Mai Si Ni Tang contains Gancao but lacks Congbai, using the sweet-slowing property to gently restore the near-extinct pulse; Bai Tong Tang lacks Gancao but includes Congbai to urgently pursue escaping Yang. Both use Zhuyezhi (Pig Bile) to clear false heat. Bai Tong Tang specifically uses Congbai to unblock True Yang. However, fearing that the ascending nature of Congbai might lead Ganjiang and Fuzi to become hyperactive, Ren Niao (Human Urine) is added to direct the action downward. Regarding Tong Mai Si Ni Tang, although it lacks Congbai in the base formula, the post-formula notes indicate adding Congbai for facial redness. If Congbai can be added, why not Ren Niao? Moreover, given that Jueyin corresponds to internal Wind-Wood, could it not present with facial redness and Dai Yang (floating Yang)? In such cases, could Congbai not be used? These methods are remedies for late-stage crises, whether from direct invasion of severe cold or complicated diseases from transmission. At this stage, pathogenic qi has turned adverse, and Yuan Qi is nearly exhausted, differing significantly from early-stage presentations of deep pulse and fever. Even in severe Liang Gan (Simultaneous Taiyang-Shaoyin) cases, Ma Huang Fu Zi Xi Xin Tang can still be tried for rescue. This correlates with the "rescue interior then release exterior" method discussed in the Taiyang chapter. The subtlety of differentiation lies precisely in the presence or absence of headache. The essence here is fully exposed. Later generations, failing to examine this carefully, recklessly created formulas for Liang Gan, falling far short of Zhang Zhongjing's (the Prefect of Changsha) wisdom by ten thousandfold.
Hui Yang Fan Ben Tang (Return Yang and Restore Foundation Decoction): Treats Yang deficiency with irritability and thirst, facial redness resembling Dai Yang, desire to sit in mud/water, and weak, nearly imperceptible pulse.
Add Renshen (Ginseng Root), Maidong (Ophiopogon Tuber), Wuweizi (Schisandra Fruit), La Cha (Preserved Tea), and Chenpi (Tangerine Peel) to Si Ni Tang. For facial redness (indicating lower deficiency), add seven stalks of Congbai (Scallion White) and a small amount of Huanglian (Coptis Rhizome). Decoct in clarified mud-water, add five spoons of Baimi (White Honey), and take cold to induce sweating. This combines Bai Tong Tang with Sheng Mai San to treat extreme Yin mimicking Yang, which is highly effective. Adding La Cha and Jiang Shui (Sour Rice Water) is appropriate. However, Chenpi seems unnecessary. When Renshen is combined with Ganjiang and Fuzi, its momentum is already strong; why rely on Chenpi's dispersing power?
Qiang Huo Fu Zi San (Notopterygium and Aconite Powder): Treats stomach cold with hiccups.
Remove Gancao (Licorice Root) from Si Ni Tang. Use Fuzi (Aconite Root) half liang, Ganjiang (Dried Ginger) two qian, add Qianghuo (Notopterygium Rhizome) and Huixiang (Fennel Fruit) half liang each, and Muxiang (Aucklandia Root) one qian. Grind into powder. Take two qian per dose, add a pinch of Yan (Salt), decoct in water, and take warm.
Muxiang San (Aucklandia Powder): Treats persistent loose stools due to deficiency-cold.
Use Si Ni Tang base: Gancao (Licorice Root) and Ganjiang (Dried Ginger) two liang each, Fuzi (Aconite Root) one liang. Add Dingxiang (Clove), Muxiang (Aucklandia Root), Roudoukou (Nutmeg), Guang Huoxiang (Patchouli), Hezi Rou (Chebulic Myrobalan Flesh), and Chishizhi (Red Halloysite) one liang each. Grind into powder. Take three qian per dose.
(Note: The Shi Ben version lacks Pao Jiang (Roasted Ginger) and adds Danggui (Angelica Sinensis).)
Leng Xiang Yin Zi (Cold Fragrance Drink): Treats summerheat complicated by consumption of raw/cold foods, leading to abdominal pain and diarrhea.
Remove Ganjiang (Dried Ginger) from Si Ni Tang. Use Gancao (Licorice Root) and Fuzi (Aconite Root) one qian each, add Caoguoren (Tsaoko Cardamom Seed), Juhong (Exocarpium Citri Grandis) one qian each, and Shengjiang (Fresh Ginger) five slices. Soak and take cold.
Jiang Shui San (Sour Rice Water Powder): Treats summerheat with diarrhea, profuse sweating, and weak pulse.
Use Si Ni Tang base: each of the three herbs five qian. Add Rougui (Cinnamon Bark) five qian, Liangjiang (Galangal Rhizome), and Banxia (Pinellia Tuber) two qian 5 fen each. (The latter two are stir-fried with vinegar). Decoct in Jiang Shui (Sour Rice Water), strain, and take cold. Note: Jiang Shui is brewed from Shumi (Glutinous Millet) and Qu (Fermentation Starter), resembling vinegar but milder. It is now used in making milk curds or rice flour cakes; adding Moutong Dou (Mung Bean) is especially good.
Yin Chen Si Ni Tang (Artemisia Four Reversal Decoction): Treats Yin Jaundice with deep-thin pulse, cold limbs, and spontaneous sweating above the waist.
Use Pao Jiang (Roasted Ginger) one qian 5 fen, Fuzi (Aconite Root) and Gancao (Licorice Root) one qian each in Si Ni Tang base. Add Yinchenshao (Artemisiae Scopariae Herba) one qian 5 fen.
Yin Chen Fu Zi Gan Jiang Tang (Artemisia, Aconite, and Dried Ginger Decoction): Treats Yin Jaundice with deep-thin pulse.
Remove Gancao (Licorice Root) from Si Ni Tang. Use Shu Fuzi (Prepared Aconite Root) three qian, Pao Jiang (Roasted Ginger) two qian. Add Baizhu (Atractylodes Macrocephala Rhizome) two qian, Doukou (Cardamom Seed), Zhishi (Immature Bitter Orange), Banxia (Pinellia Tuber), Fuling (Poria), Zexie (Alisma Rhizome), Juhong (Exocarpium Citri Grandis) eight fen each, Yinchenshao (Artemisiae Scopariae Herba) one qian, and Shengjiang (Fresh Ginger) five slices.
