[Sini Tang / Four Reversal Decoction] (From Zhang Zhongjing) Treats Taiyin, Shaoyin, and Jueyin cold damage (San Yin Shang Han). (Sini Tang is the principal formula for Shaoyin disease, but it is generally applicable to all three Yin meridians. In Taiyang syndrome, if the pulse is deep, this formula may also be used.)
Symptoms include: body pain, abdominal pain, diarrhea with undigested food (In San Yin interior cold, spontaneous diarrhea is common), aversion to cold without thirst, and cold limbs. (It is named Sini Tang because it treats reversal cold of the limbs. The limbs are the root of all Yang meridians. Cold causes blood vessels to coagulate and stagnate, and Yang Qi cannot distribute, resulting in whole-body pain and cold hands and feet.) Alternatively, there may be no aversion to cold, red face, and restlessness (Yin excess repels Yang to the exterior), presenting as interior cold with exterior heat. There may be dry retching (Cold fluid in the diaphragm), or sore throat (Deficient fire flaming upward), and a pulse that is deep, faint, thin, and nearly imperceptible. (Shaoyin pulses can be deep, tight, or rapid, but Zhang Zhongjing generalizes them as faint and thin. A deep pulse must be pressed heavily to be felt; tightness and rapidity are seen within the deep and thin quality, unlike Yang syndromes which are floating, large, tight, and forceful. Xue Zhenqi said: People know rapidity indicates heat, but do not know that rapidity seen within a deep and thin pulse indicates extreme cold, a true Yin-cold syndrome. If the Ying Qi pulse beats seven or eight times per breath, but feels powerless upon pressure, one must examine this deeply.)
Ingredients: Aconiti Radix (Fu Zi) (One piece, raw use)
Zingiberis Rhizoma (Gan Jiang) (1 liang)
Glycyrrhizae Radix et Rhizoma Praeparata cum Melle (Zhi Gan Cao) (2 liang, honey-fried).
Take cold. For red face, Yang is repelled upward; add nine stalks of Scallion Stem (Cong Bai) to unblock Yang.
(This preparation...)
When Cold pathogen invades the interior, treat with sweet-hot methods. Therefore, use large hot agents like Ginger and Aconite to extend and emit Yang Qi and disperse Cold pathogen from the exterior. (Raw Aconite can also release the exterior.)
Reason for taking cold...
For body pain... In acute cases... Chengqi Decoction... Reversal cold... Reversal and smooth flow correspond...
Add Ginseng Radix et Rhizoma (Ren Shen) 1 liang, named Sini Tang plus Ginseng Decoction. Treats aversion to cold, faint pulse, recurrent diarrhea, and cessation of diarrhea due to exhaustion of fluids/blood. (Although diarrhea has stopped, fluids and essence have been exhausted, therefore...)
Remove Aconite, use Glycyrrhizae Radix et Rhizoma (Gan Cao) 4 liang and Zingiberis Rhizoma (Gan Jiang) 2 liang, named Gancao Ganjiang Tang / Licorice and Ginger Decoction. Treats cold damage with floating pulse, spontaneous sweating, frequent urination, slight aversion to cold, and cramped legs. Due to mistaken attack on the exterior with Guizhi Tang, reversal cold occurred, with dry throat, restlessness, vomiting, and regurgitation; give this decoction to restore Yang. (Floating pulse, spontaneous sweating, frequent urination, and aversion to cold indicate insufficient Yang. Attacking the exterior further depleted Yang, leading to reversal cold. Therefore, use Licorice to benefit Qi and Ginger to assist Yang to restore Yang.)
