朱肱曰。有发热恶寒。躁烦。手足温。而脉反浮紧者。有寒多热少。不烦躁。手足微冷。而脉反浮缓者。此名伤风
见寒脉。伤寒见风脉也。盖发热恶寒烦躁手足温。为中风候。脉浮紧。为伤寒脉。是中风见寒脉也。寒多热少不烦躁手
足微厥。为伤寒候。脉浮缓。为中风脉。是伤寒见风脉也。中风见寒脉。伤寒见风脉。宜服大青龙汤。盖大青龙症。脉
似桂枝反无汗。病似麻黄反烦躁是也。（脉弱有汗。为桂枝症。脉紧不烦躁。为麻黄症。）大青龙汤治病。与麻黄汤症相
似。但病尤重。而又加烦躁者。用大青龙也。以其风寒俱盛。故青龙汤添麻黄作六两。又似合桂枝汤药味在内。添石膏。
所以为紧。此治荣卫俱病。若症不审。误用大青龙。则发汗多伤人。（以其有烦躁一症。故可用大青龙汤。）
陶华曰。热盛而烦。手足自温。脉浮而紧。此伤风见寒脉也。不烦少热。四肢微厥。脉浮而缓。
此伤寒见风脉也。二者为荣卫俱病。法虽用大青龙。此汤险峻。不可轻用。须风寒俱盛。又加烦
躁。方可与之。不若羌活冲和汤。为神药也。一法。用桂枝麻黄汤。
Li said: The Lung governs the skin and hair, connects with the Bladder, and is most susceptible to external pathogens. This manifests as new-onset cough, aversion to wind, nasal congestion, heavy voice, and sneezing. Chaihu Banxia Tang (Bupleurum and Pinellia Decoction) or Shen Su Yin (Ginseng and Perilla Drink) may be used. In cold months, Mahuang Xingren Yin (Ephedra and Apricot Seed Decoction) is indicated. For severe cases presenting with headache, body pain, aversion to cold, fever, dry throat, and hoarseness, Chaihu Guizhi Tang (Bupleurum and Cinnamon Twig Decoction) or Fangfeng Chonghe Tang (Saposhnikovia Harmonizing Decoction) may be administered. For severe headache, Chuanxiong Chatiao San (Ligusticum Tea-Regulating Powder) is used. For excessive phlegm, Jinfeicao San (Boerhavia Powder) is applied. If accompanied by heat, Renshen Baidu San (Ginseng Resisting Toxins Powder) or Shengma Gegen Tang (Cimicifuga and Kudzu Root Decoction) are suitable. If accompanied by cold, Shishen Tang (Ten Deities Decoction) is used. If complicated by cold-dampness, Xiaofeng Baijie San (Wind-Dispersing Hundred-Resolving Powder) is indicated. If complicated by dampness, Shenzhu San (Divine Artisan Powder) is used. If complicated by summerheat, Xiangge Tang (Aromatic Kudzu Decoction) is prescribed. For epidemic diseases (Shixing Bing), Chaihu Shengma Tang (Bupleurum and Cimicifuga Decoction) is used. For those who consume rich foods, have chronic phlegm-fire, and suffer from frequent nasal congestion, runny nose, heavy voice, and cough, which worsen slightly upon external contraction, Fengtong Sheng San (Wind-Blocking Supreme Powder) is indicated. Alternatively, Dahuang Huangqin Wan (Rhubarb and Scutellaria Pills) in equal parts, taken with plain water, may be used. For those with inherent deficiency, only Fangfeng (Saposhnikovia Radix), Qianghuo (Notopterygii Rhizoma et Radix), and Chuanxiong (Chuanxiong Rhizoma) should be used, with tonifying or phlegm-resolving herbs added as appropriate. For food stagnation, add Baizhu (Atractodis Macrocephalae Rhizoma), Qingpi (Aurantii Fructus Immaturus Pericarpium), Chenpi (Citri Reticulatae Pericarpium), Shanzha (Crataegi Fructus), and Maiya (Hordei Fructus Germinatus). If complicated by exposure to cold and consumption of cold drinks, add Shengjiang (Zingiberis Rhizoma Recens) and Rougui (Cinnamomi Cortex). If complicated by sexual exhaustion, add Renshen (Ginseng Radix), Baizhu (Atractodis Macrocephalae Rhizoma), Danggui (Angelicae Sinensis Radix), and Dihuang (Rehmanniae Radix Praeparata). If complicated by overwork damaging Qi, Buzhong Yiqi Tang (Middle-Boosting Qi-Enriching Decoction) with Qianghuo and Fangfeng is used. For severe wind-deficiency, Qianghuo Wan (Notopterygium Pill) or Jiawei Wujin Wan (Modified Black Gold Pill) are indicated. If wind pathogen transmits inward, treatment follows the methods for Shanghan (Cold Damage). Wind can dry blood and disperse Qi; thus, ancient practitioners often used Guizhi Bawu Tang (Cinnamon Twig Eight-Substance Decoction) and similar formulas. For chronic non-resolving cases, Sanbai Tang (Three Whites Decoction) modified is suitable for astringency. One must strictly avoid dispersing and draining methods. Even at onset, if it is not cold weather with anhidrosis, Mahuang (Ephedrae Herba) is contraindicated.
Zhu Gong said: There are cases where patients present with fever, aversion to cold, restlessness, warm hands and feet, yet the pulse is surprisingly floating and tight. There are also cases where there is more cold than heat, no restlessness, slightly cold hands and feet, yet the pulse is surprisingly floating and slow. These are named "Shangfeng Jian Hanmai" (Wind-Injury exhibiting Cold-Damage Pulse) and "Shanghan Jian Fengmai" (Cold-Damage exhibiting Wind-Injury Pulse). Generally, fever, aversion to cold, restlessness, and warm extremities indicate Zhongfeng (Wind-Strike); a floating-tight pulse indicates Shanghan (Cold-Damage). Thus, Zhongfeng exhibits a Cold-Damage pulse. Conversely, more cold than heat, no restlessness, and slightly cold extremities indicate Shanghan; a floating-slow pulse indicates Zhongfeng. Thus, Shanghan exhibits a Wind-Injury pulse. For these presentations, Daqinglong Tang (Great Azure Dragon Decoction) is appropriate. The Daqinglong syndrome resembles Guizhi Tang pattern but without sweating, and resembles Mahuang Tang pattern but with restlessness. (Weak pulse with sweating indicates Guizhi Tang pattern; tight pulse without restlessness indicates Mahuang Tang pattern.) The disease treated by Daqinglong Tang is similar to Mahuang Tang pattern but more severe, compounded by restlessness, hence Daqinglong Tang is used. Because both wind and cold are abundant, the dosage of Mahuang is increased to six liang, and the formula incorporates ingredients resembling Guizhi Tang along with Shigao (Gypsum Fibrosum), making it potent. This treats simultaneous Ying and Wei pathology. If the syndrome is not carefully differentiated and Daqinglong Tang is mistakenly used, excessive sweating will damage the body. (The presence of restlessness justifies the use of Daqinglong Tang.)
Tao Hua said: Excessive heat with restlessness, naturally warm hands and feet, and a floating-tight pulse indicate Shangfeng Jian Hanmai (Wind-Injury exhibiting Cold-Damage Pulse). No restlessness, less heat, slightly cold limbs, and a floating-slow pulse indicate Shanghan Jian Fengmai (Cold-Damage exhibiting Wind-Injury Pulse). Both conditions involve simultaneous Ying and Wei pathology. Although Daqinglong Tang is theoretically applicable, this decoction is hazardous and should not be used lightly. It is only suitable when both wind and cold are abundant and restlessness is present. It is preferable to use Qianghuo Chonghe Tang (Notopterygium Harmonizing Decoction), which is a miraculous remedy. Another method involves using Guizhi Mahuang Tang (Cinnamon Twig and Ephedra Decoction).
