帝曰∶阴盛生内寒奈何？曰∶厥气上逆，寒气积于胸中而不散。不散则温气去，寒独留则血凝
。血凝则脉不通，其脉盛大以涩，故中寒。按诸病上下，所出水液澄澈清冷， 瘕 疝，坚痞腹满
急痛，下利清白，食已不饥，吐利腥秽，屈伸不便，厥逆禁固，皆属于寒。盖痼冷之证，乃真阳耗
散，脾胃亏伤，又啖生冷难化之物。或受风寒阴湿，经年累月，日久乃成。则脾胃因而渍积，脏腑
致成虚寒。及有外邪触犯，内外邪相感，忽然而作手足厥冷、战栗憎寒，呕吐涎沫，脐腹绞痛，或常得大便洞泄，小便
频数，饮食不化，咳嗽， 疝等证。其脉沉而迟，治宜温养脾胃，补益气血，助阳固本。

The Yellow Emperor asked: Why does an excess of Yin cause internal cold? The answer is: Jue Qi (rebellious Qi) moves upward, causing cold Qi to accumulate in the chest without dispersing. If it does not disperse, the warming Qi departs, leaving only cold Qi, which causes blood coagulation. Blood coagulation leads to obstruction of the vessels; the pulse appears large yet choppy, thus indicating Zhong Han (Cold invading the Middle Jiao). Observing various diseases, any fluid discharged from above or below that is clear and cold, as well as Zha Shan (abdominal masses and hernia), hard and fixed fullness with abdominal distension and acute pain, diarrhea with clear white stool, lack of hunger after eating, vomiting with fishy or foul odor, difficulty in flexing and extending the limbs, Jue Ni (cold extremities) with stiffness and immobility, all belong to Cold syndromes. Generally, Gu Leng (stubborn cold) arises from the depletion and dispersion of True Yang, damage to the Spleen and Stomach, and the consumption of raw, cold, and indigestible foods. Alternatively, it results from exposure to Wind-Cold and Yin-Dampness over years, eventually forming this condition. Consequently, the Spleen and Stomach become stagnant, and the Zang-Fu organs develop deficiency-cold. When external pathogens invade, internal and external evils interact, suddenly causing symptoms such as cold extremities, shivering and aversion to cold, vomiting of saliva and foam, colicky pain in the umbilical and abdominal regions, frequent loose stools, frequent urination, undigested food in stool, cough, and Shan (hernia). The pulse is deep and slow. Treatment should focus on warming and nourishing the Spleen and Stomach, tonifying Qi and Blood, assisting Yang, and consolidating the Root.
The main formula is Lizhong Tang (Cinnamon Twig and Ginger Decoction), consisting of: Renshen (Ginseng Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Ganjiang (Zingiberis Rhizoma), and Zhigancao (Glycyrrhizae Radix et Rhizoma Preparata).
If the cold is severe, add Fuzi (Aconiti Lateralis Radix Praeparata) or Chuanwu (Aconiti Radix). Decoct with seven slices of Shengjiang (Zingiberis Rhizoma Recens) and two black dates (Heizao, Ziziphi Jujubae Fructus Nigricans) in water. If the condition remains unrelieved, add Dingxiang (Caryophylli Flos), Muxiang (Aucklandiae Radix), Sharen (Amomi Fructus), Baidoukou (Cardamomi Fructus), Hujiao (Piperis Longi Fructus), Rougui (Cinnamomi Cortex), Huixiang (Foeniculi Fructus), Chenxiang (Aquilariae Lignum Resinatum), and Biba (Piperis Kadsurae Fructus), selected according to severity, ground into fine powder, and mixed into the decoction for ingestion. All the above herbs are agents that warm the Spleen and Stomach and heat the Zang-Fu organs; they should be added or subtracted according to the syndrome.
For Qi and Blood deficiency, use Shiquan Dabu Wan (Ten Ingredients Great Tonifying Pill); for cold exhaustion of the Lower Yuan (Kidney Yang deficiency leading to cold and fatigue), use Guifu Bawei Wan (Cinnamon and Aconite Eight-Ingredient Pill) (see both formulas under Tonification).
Dudou Formula (Treats stubborn cold accumulation in the abdomen with miraculous effect. Also benefits the Dantian and Shenque acupoints, aiding fertility. Suitable for men and women. Contraindicated during pregnancy.)
Ingredients: Tanxiang (Santalum Album Lignum) and Paicao (Hedyotis Diffusa Herba, each 1 liang); Chenxiang (Aquilariae Lignum Resinatum) and Dingxiang (Caryophylli Flos, each 5 qian); Matixin (Alpiniae Officinarum Rhizoma), Guanglingling (Lingzhi Xiang), Baizhi (Angelicae Dahuricae Radix), and Dingpi (Dingxiang Cortex, each 6 qian); Gansong (Nardostachyos Radix et Rhizoma), Fuzi (Aconiti Lateralis Radix Praeparata), and Ruxiang (Olibanum, each 2 qian); Shexiang (Moschus, 5 fen).
Grind the above into powder, mix with Ai Mian (moxa cotton), place inside a cloth pouch sewn securely with thread to prevent shifting. Wrap tightly around the lower abdomen. Initially wear for one night, then remove the next day. Gradually extend to wearing for two nights before removing, then five nights before removing, until it can be worn continuously.
Bathing Method: Treats deficiency-cold of the Lower Yuan and all cold diseases, such as cold pain in the waist and abdomen, metrorrhagia and leukorrhea, and painful masses in the lower abdomen.
Ingredients: Jiaomu (Zanthoxylum Semen), Chuanwu (Aconiti Radix), Xixin (Asari Radix et Rhizoma), Ganjiang (Zingiberis Rhizoma), and Guangui (Cinnamomi Cortex, equal parts, ground into powder). Decoct and wash the lower body; this is excellent.
