头痛、项部僵硬、腰脊强痛、发热恶寒、恶心，这是足太阳膀胱经受邪的表现。假如起初先出现恶寒症状的，属于本经病；随后才出现发热的，属于标经病。如果有一点点头痛、恶寒且身体发热，不论患病天数多少，都应当立即使用发散法治疗，自然热退身凉，会有什么变证呢？
表虚而自汗出的，是风邪损伤卫气所致，适宜用固表实卫的方法。表实而无汗出的，是寒邪损伤营血所致，适宜用发表散寒的方法。
冬季正值伤寒，使用升阳发表汤（即加减麻黄汤）。冬季伤风，使用疏邪实表汤（即加减桂枝汤）。春秋季节无汗的，使用羌活冲和汤以发表；有汗的，使用加减冲和汤以实表。夏季无汗的，使用神术汤；有汗的，使用前文提到的加减冲和汤。
眼睛疼痛、鼻干、失眠、轻微恶寒，这是足阳明胃经受邪的表现。假如起初先出现眼睛疼痛、恶寒且身体发热的，属于阳明经的本病；随后出现潮热、自汗、说胡话（谵语）、口渴、大便干结的，属于正阳明胃腑的标病。本经病适宜用解肌法，标病适宜急用下法，具体要看病情轻重缓急来选用。
眼睛疼痛、鼻干、轻微恶寒、身体发热，病位在经络。潮热、自汗、说胡话、口渴、大便干结、不恶寒，病位在腑。
轻微恶寒，自然伴有眼眶痛、鼻干、失眠的，使用柴葛解肌汤（即加减葛根解肌汤）。口渴且有汗但病不解的，使用如神白虎汤（即加减白虎汤）。出现潮热、自汗、说胡话、口渴、掀开衣被、扬手掷足、斑疹发黄、狂乱不安、不恶寒反而怕热、大便干结的，轻症用大柴胡汤，重症则在三承气汤中选用，这些方剂都在秘方六乙顺气汤的基础上进行加减治疗。
Headache, stiffness of the neck and occiput, rigidity of the lower back and spine, fever with aversion to cold, and nausea are manifestations of a pathogenic invasion of the Foot-Taiyang Bladder Channel. If chills appear first, it is a disease of the root (Ben); if fever appears subsequently, it is a disease of the branch (Biao). If there is even slight headache, aversion to cold, and body heat, regardless of the number of days since onset, dispersing methods should be applied immediately. Naturally, the heat will subside and the body will become cool; what complications could arise?
Spontaneous sweating due to exterior deficiency indicates that wind has injured the Defensive Qi (Wei Qi); solidifying the exterior is indicated. Absence of sweating due to exterior excess indicates that cold has injured the Nutritive Blood (Ying Xue); releasing the exterior is indicated.
A floating and tight pulse with strength indicates Cold Damage (Shang Han). A floating and slow pulse without strength indicates Wind Injury (Shang Feng).
In winter, when contracting true Cold Damage, Sheng Yang Fa Biao Tang (Ascending Yang and Releasing Exterior Decoction) [i.e., Modified Ma Huang Tang] is used. In winter, when contracting wind, Shu Xie Shi Biao Tang (Dispersing Pathogens and Solidifying Exterior Decoction) [i.e., Modified Gui Zhi Tang] is used. In spring and autumn, in cases without sweating, Qiang Huo Chong He Tang (Notopterygium Harmonizing Decoction) is used to release the exterior; in cases with sweating, Jia Jian Chong He Tang (Modified Harmonizing Decoction) is used to solidify the exterior. In summer, in cases without sweating, Shen Zhu Tang (Divine Operation Decoction) is used; in cases with sweating, the aforementioned Jia Jian Chong He Tang is used.
Eye pain, dry nose, insomnia, and mild aversion to cold are manifestations of a pathogenic invasion of the Foot-Yangming Stomach Channel. If eye pain and aversion to cold with body heat appear first, it is a disease of the Yangming Channel (root). If tidal fever, spontaneous sweating, delirium, thirst, and firm stool appear subsequently, it is a disease of the proper Yangming Stomach Fu-organ (branch). The root condition is suitable for muscle-releasing methods, while the branch condition requires urgent purgation; one must judge the situation carefully to apply them appropriately.
Eye pain, dry nose, mild aversion to cold, and body heat indicate the disease is in the channels. Tidal fever, spontaneous sweating, delirium, thirst, firm stool, and absence of aversion to cold indicate the disease is in the fu-organs.
A slightly surging pulse indicates a channel disease. A deep and rapid pulse indicates a fu-organ disease.
Mild aversion to cold accompanied naturally by orbital pain, dry nose, and insomnia: use Chai Ge Jie Ji Tang (Bupleurum and Pueraria Muscle-Releasing Decoction) [i.e., Modified Ge Gen Jie Ji Tang]. Thirst with sweating but unresolved disease: use Ru Shen Bai Hu Tang (Miraculous White Tiger Decoction) [i.e., Modified Bai Hu Tang]. Tidal fever, spontaneous sweating, delirium, thirst, throwing off clothes and bedding, waving hands and kicking feet, yellowish macules, mania and confusion, absence of aversion to cold but preference for heat, and firm stool: for mild cases, Da Chai Hu Tang (Major Bupleurum Decoction) is used; for severe cases, one of the Three Cheng Qi Decoctions is selected. All these treatments involve modifications based on Liu Yi Shun Qi Tang (Six-Eight Smooth Qi Decoction) found in secret recipes.
