桂枝 芍药 生姜（各三两） 大枣（十二枚） 甘草（二两） 附子（三枚）
太阳病发汗，遂漏不止，其人恶风，小便难，四肢微急，难以屈伸者，此方主之。风湿
相搏，身体疼烦，不能转侧者，亦此方主之。
发汗遂漏不止，则虚其表而亡阳，阳虚则无以卫外，故其人恶风；小便难者，经虚腑亦
虚，而膀胱之气不化，不化则不出，故小便难。汗多，表亡津液，则无以养筋，故四肢微急，
难以屈伸。用桂枝汤，所以和在表之营卫；加附子，所以壮在表之元阳。风湿相搏者，风邪
与湿邪相搏激也。然何以知之？若风邪为患，必分六经，今身体尽是疼烦，不能转侧，则无
六经可辨之证，故知其风湿相搏也。与桂枝汤解在表之风，加附子以温寒湿。
麻黄（去节） 细辛（去土，各二两） 附子（一枚）
少阴病，始得之，反发热，脉沉者，此方主之。
病发于阴者，当无热。今少阴病始得之，何以反发热也？此乃太阳经表里相传之证故耳！
盖太阳膀胱经与少阴肾经相为表里，肾经虚，则太阳之邪由络直入肾脏。余邪未尽入里，故
表有发热，真寒入肾，故里有脉沉。有太阳之表热，故用麻黄以发汗；有少阴之里寒，故用
辛、附以温中。

少阴病，心烦不得卧者，此方主之。
寒邪径中三阴者，名曰阴证，始终只是一经，不复再传。今自三阳经传来，虽至三阴，
犹曰阳证。所以有传、有不传者，以阴静阳动也。少阴病者，有舌干口燥、欲寐诸证也。欲
寐而不行寐，故曰心烦不得卧也。少阴者，水脏，水为热灼，不足以济火，故心烦。阳有余
者，泻之以苦，故用黄芩、黄连之苦；阴不足者，补之以甘，故用鸡黄、阿胶之甘；阴气耗
者敛之以酸，故复佐以芍药之酸。

太阳病（太阳经受邪所致的病证）发汗后，导致汗出淋漓不止，患者怕风，小便困难，四肢轻微拘急，难以屈伸的，此方主治。风湿之邪相互搏结，身体疼痛烦扰，不能翻身转侧的，也以此方主治。
发汗后导致汗出不止，则使体表虚弱而阳气亡失，阳气虚则无法护卫肌表，所以患者怕风；小便困难，是因为经络和脏腑皆虚，膀胱的气化功能失常，气化不行则尿液不出，所以小便困难。汗出过多，体表津液亡失，则无法滋养筋脉，所以四肢轻微拘急，难以屈伸。使用桂枝汤，是为了调和在表的营卫之气；加入附子，是为了壮旺在表的元阳。所谓风湿相搏，是指风邪与湿邪相互激荡。然而怎么知道是这种情况呢？如果是风邪致病，必然分属于六经的不同证候，现在全身都疼痛烦扰，不能转侧，就没有可以辨别为某一经的病证，因此知道这是风湿相搏。给予桂枝汤以解除在表的风邪，加入附子以温散寒湿。
少阴病（少阴经受邪所致的病证），初起时，反而出现发热，脉象沉的，此方主治。
病发于阴经者，应当没有发热。现在少阴病初起，为什么反而发热呢？这是因为太阳经与少阴经表里相传的病证缘故！大概太阳膀胱经与少阴肾经互为表里，肾经虚弱，则太阳的邪气由络脉直接侵入肾脏。余邪尚未完全入里，所以在表有发热，真寒已入肾，所以在里有脉沉。因为有太阳的表热，所以用麻黄来发汗；因为有少阴的里寒，所以用细辛、附子来温中。
黄连（去毛，炒，四两）、黄芩（一两，炒）、鸡子黄（二枚，生用）、芍药（二两，炒）、阿胶（用蚌粉炒，三两）
少阴病，心中烦躁不得安卧的，此方主治。
寒邪直接中伤三阴经的，称为阴证，始终只涉及一经，不再传变。现在从三阳经传来，虽然到了三阴经，仍然称为阳证。之所以有传变和不传变的区别，是因为阴主静、阳主动的缘故。少阴病的表现，有舌干口燥、想睡觉等症状。想睡却睡不着，所以称为心烦不得卧。少阴属水脏，水被热邪灼烧，不足以制约火邪，所以心烦。阳气有余的，用苦味药泻之，所以用黄芩、黄连的苦味；阴气不足的，用甘味药补之，所以用鸡蛋黄、阿胶的甘味；阴气耗损的，用酸味药收敛之，所以又辅以芍药的酸味。
Guizhi Tang (Cinnamon Twig Decoction): Cinnamon Twig (Guizhi, *Cinnamomi Ramulus*), White Peony Root (Baishao, *Paeoniae Radix Alba*), Fresh Ginger (Shengjiang, *Zingiberis Rhizoma Recens), Jujube (Dazao, *Ziziphi Jujubae Fructus)*, Licorice Root (Gancao, *Glycyrrhizae Radix et Rhizoma)*, Prepared Aconite Root (Fuzi, *Aconiti Lateralis Radix Praeparata*).
In Taiyang disease (disease of the Taiyang channel), after sweating therapy, if perspiration continues unceasingly, accompanied by aversion to wind, difficulty in urination, slight stiffness of the four limbs making flexion and extension difficult, this formula is indicated. In cases where Wind-Dampness pathogens interfere with each other, causing severe body pain and restlessness, preventing turning over or shifting position, this formula is also indicated.
Unceasing perspiration following sweating therapy depletes the exterior and causes Yang collapse. When Yang is deficient, it cannot protect the exterior, hence the aversion to wind. Difficulty in urination arises because both the channels and the fu-organs are deficient; the Qi transformation of the Bladder fails, leading to an inability to excrete urine. Excessive sweating depletes Body Fluids at the exterior, which fail to nourish the sinews, resulting in slight stiffness of the four limbs and difficulty in movement. Guizhi Tang is used to harmonize Ying (Nutritive) and Wei (Defensive) Qi at the exterior; adding Fuzi strengthens the Primordial Yang at the exterior. "Wind-Dampness interfering" refers to the mutual agitation of Wind and Dampness pathogens. How do we know this? If Wind were the sole pathogen, symptoms would typically follow the patterns of the Six Channels. However, since the entire body suffers from pain and restlessness with an inability to turn, there are no specific channel patterns to distinguish, thus indicating Wind-Dampness interference. Guizhi Tang resolves Wind at the exterior, while Fuzi warms and dispels Cold-Dampness.
Ephedra Herb (Mahuang, *Ephedrae Herba* - removed nodes), Asarum Root (Xixin, *Asari Radix et Rhizoma* - removed soil, 2 liang each), Prepared Aconite Root (Fuzi, *Aconiti Lateralis Radix Praeparata*, 1 piece).
In Shaoyin disease (disease of the Shaoyin channel), upon initial onset, if there is fever contrary to expectation and a deep pulse, this formula is indicated.
Diseases originating from Yin channels should not present with fever. Why does Shaoyin disease present with fever upon initial onset? This is due to the transmission between the Taiyang and Shaoyin channels, which are interior-exterior pairs. The Taiyang Bladder Channel and Shaoyin Kidney Channel are interior-exterior partners. When the Kidney Channel is deficient, Taiyang pathogens enter directly into the Kidneys via the collaterals. Since residual pathogens have not fully entered the interior, there is fever at the exterior; true Cold has entered the Kidneys, hence the deep pulse at the interior. Because there is Taiyang exterior heat, Mahuang is used to induce sweating; because there is Shaoyin interior cold, Xixin and Fuzi are used to warm the interior.
Coptis Rhizome (Huanglian, *Coptidis Rhizoma* - removed hairs, stir-fried, 4 liang), Scutellaria Root (Huangqin, *Scutellariae Radix*, stir-fried, 1 liang), Egg Yolk (Jizihuang, *Galli Yolk Sac*, raw, 2 pieces), White Peony Root (Baishao, *Paeoniae Radix Alba*, stir-fried, 2 liang), Donkey-Hide Gelatin (Ejiao, *Colla Corii Asini* - stir-fried with clam powder, 3 liang).
In Shaoyin disease, if there is mental restlessness and an inability to sleep, this formula is indicated.
When Cold pathogens directly strike the Three Yin channels, it is named Yin Syndrome, remaining within one channel without further transmission. However, when transmitted from the Three Yang channels, even if reaching the Three Yin channels, it is still termed Yang Syndrome. The difference in transmission lies in the nature that Yin is static and Yang is active. Symptoms of Shaoyin disease include dry tongue and mouth, and somnolence. The desire to sleep but inability to do so results in mental restlessness and insomnia. Shaoyin belongs to the Water organ; when Water is scorched by Heat, it cannot control Fire, leading to restlessness. For excess Yang, bitter flavors are used to drain, hence Huangqin and Huanglian are used for their bitterness. For insufficient Yin, sweet flavors are used to tonify, hence egg yolk and Ejiao are used for their sweetness. For depleted Yin Qi, sour flavors are used to astringe, hence Baishao is added for its sourness.
