太阳膀胱，与少阴肾，相为表里。肾虚，故太阳之邪，直入而脉沉，余邪未尽入里
此证谓之表里传，非两感也。）

仲景曰∶少阴病，得之二三日，麻黄附子甘草汤微发汗，以二三日无里证，故微发汗也。

(Zhang Zhongjing) Treats Shaoyin disease (Shaoyin Syndrome) of Cold Damage (Shanghan), where upon initial onset, there is fever and a deep pulse. (Shaoyin disease is characterized by a faint and thin pulse and a desire to sleep with listlessness. The Foot-Taiyang Bladder channel and the Foot-Shaoyin Kidney channel are interior-exteriorly related. Due to Kidney deficiency, pathogenic factors from the Taiyang channel directly invade, causing a deep pulse, while residual pathogens have not fully entered the interior. This condition is termed "transmission between exterior and interior," not simultaneous contraction of two channels.)
Ephedrae Herba (Mahuang, 麻黄) (2 liang, remove nodes)
Cibotii Rhizoma (Xixin, 细辛) (1 liang)
Aconiti Lateralis Radix Praeparata (Fuzi, 附子) (1 piece, prepared, peel removed, cut into 8 slices)
Boil Ephedrae Herba first, remove the foam on the surface, then add Cibotii Rhizoma and Aconiti Lateralis Radix Praeparata to boil together.
[Note: The original text contains fragmented sentences regarding modifications. It implies that if specific conditions arise or for a modified prescription, Cibotii Rhizoma is removed and Glycyrrhizae Radix et Rhizoma is added, naming it Mahuang Fuzi Gancao Tang.]
Zhang Zhongjing stated: "In Shaoyin disease, after two or three days, use Mahuang Fuzi Gancao Tang to induce slight sweating. Because there are no interior symptoms after two or three days, only slight sweating is required."
(Qian Zhongyang [Qian Yi]) Treats Yangming Cold Damage or Wind-Strike, presenting with headache and body pain, fever and aversion to cold, anhidrosis, thirst, eye pain, nasal dryness, inability to lie down comfortably, as well as Yangming macules (ban), where rashes attempt to emerge but fail to do so, alternating chills and fever, and prone to epidemic diseases. (All three Yang channels can cause headaches, thus headache belongs to the exterior. Pain can occur in all six channels. If in the Yang channels, it manifests as irritability, pain, and stiffness. Wind-cold at the exterior causes fever and aversion to cold. External constriction by cold causes anhidrosis. Heat entering the interior causes thirst. The Yangming meridian passes through the nose and flanks the eyes, causing eye pain and nasal dryness. Yangming corresponds to the Stomach; when the Stomach is affected by pathogens, restlessness occurs. This is the initial stage of pathogen invasion, not yet reaching the zang-fu organs. When yang pathogens enter the stomach, resulting in interior excess and exterior deficiency, macules appear. Small spots like mosquito bites are called rashes (zhen); large patterns like brocade are called macules (ban).)
Cimicifugae Rhizoma (Shengma, 升麻) (3 qian)
Puerariae Lobatae Radix (Gegen, 葛根)
Paeoniae Radix Alba (Baishao, 芍药) (2 qian)
Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) (1 qian, honey-fried)
Decoct with fresh ginger. For headache, add Ligustici Chuanxiong Rhizoma (Chuanxiong, 川芎) and Angelicae Dahuricae Radix (Baizhi, 白芷). (Chuanxiong and Baizhi are key herbs for head and face pain.) For heat, add Coptidis Rhizoma (Huanglian, 黄连) and Gypsum Fibrosum (Shigao, 石膏) etc. For sore throat, add Platycodonis Radix (Jiegeng, 桔梗) and Scrophulariae Radix (Xuanshen, 玄参) etc. For emerged macules, add Ginseng Radix (Renshen, 人参) etc. For weak stomach and poor appetite, add Tangerine Peel (Chenpi, 陈皮) and Poria (Fuling, 茯苓) etc.
The Yangming channel is abundant in qi and blood. When cold pathogens injure the body, they cause stagnation of qi and blood. Acrid substances can reach the exterior, and light substances can resolve excess. Therefore, light and acrid herbs such as Shengma and Gegen are used. Puerariae Lobatae Radix serves as the sovereign herb, Cimicifugae Rhizoma as the assistant herb, and Glycyrrhizae Radix et Rhizoma and Paeoniae Radix Alba harmonize the middle jiao. (Shengma and Gancao raise yang and resolve toxicity, thus also treating seasonal epidemics. Pathogens of seasonal epidemics first enter the stomach, hence stomach-channel herbs are used.) Do not use this formula if Shanghan pathogens have not yet entered the Yangming channel, lest it draw exterior pathogens into the Yangming channel. Do not use if macules and rashes have already emerged, lest it further deplete the exterior qi. (If measles or smallpox red spots have appeared, it should not be taken. Yangming is the interior of the exterior; Shengma and Gegen are correct herbs for Yangming. Whenever macules and rashes are about to emerge but have not yet done so, this decoction is suitable to vent the toxin. Do not immediately use cold-natured drugs to attack heat. Nor should sweating or purging methods be used, which would deplete the qi of both exterior and interior. If internal heat is severe, add Coptidis Rhizoma, Rhinocerotis Cornu (Xijiao, 犀角), Indigo Naturalis (Qingdai, 青黛), Isatidis Radix (Daqinggen, 大青根), Anemarrhenae Rhizoma (Zhimu, 知母), Gypsum Fibrosum, Scutellariae Radix (Huangqin, 黄芩), Phellodendri Cortex (Huangbai, 黄柏), and Scrophulariae Radix. If the macule tendency subsides slightly, accompanied by tidal fever, delirium, and constipation, Da Chaihu Tang plus Mangxiao (Mangpiao, 芒硝) may be used, or Tiaowei Chengqi Tang to purge.)
