(这是越婢汤加入四两白术。方剂详情见下文。)治疗里水证,表现为全身及面目黄肿,脉象沉,小便不通利。
若患水气病,假设小便自然通利,这是津液耗伤的表现,因此会出现口渴症状,此汤剂主治此类情况。
歌诀说:里水证脉象沉,面目发黄且浮肿,风水相搏湿邪为祸殃,专需越婢汤平息风水,四两白术擅长祛除湿邪。
陈元犀按语:水热互结蓄积,气机因湿邪阻滞,导致阳气不能通达体表而发汗,体内也不能运化水气而利尿,因此形成水气病。
有人说:针对湿气,应通过利小便来治疗,这是分消表里的治法。也有人说:越婢散去除肌表的水气,加入白术可以止渴生津。我认为:哪有小便自利、津液耗伤而致口渴的人,还继续使用此汤剂,不顾虑它会进一步重伤津液呢?
(见于湿病篇。)治疗风水证,脉象浮,身体沉重,出汗且恶风者,此汤剂主治。
陈元犀按语:恶风是因为风邪损伤了肌腠;身体沉重是因为湿邪损伤了经络;脉象浮说明病位在表。为什么不用桂枝、麻黄?所以用黄芪而不固守常规。
治疗风水证,恶风,全身都浮肿,脉象浮且不渴,持续自汗出,没有大热,此汤剂主治。
麻黄(六两),石膏(半斤),生姜(三两),甘草(二两),大枣(十二枚)。
以上五味药,用水六升,先煮麻黄,去掉上面的泡沫,再加入其他药物,煮取三升,分三次温服。若恶风,加附子一枚。
歌诀说:全身浮肿多属风邪,水随风动如涌巨波,两草三姜十二枣,八两石膏配六两麻黄调和。
陈元犀按语:恶风是风邪所致,全身浮肿是水邪所致,脉象浮是风邪发作的表现。风为阳邪,风动则水火交战。此处用药已酝酿成猛烈之势,一物而掌握两个关键要点。又用大枣、甘草安护中焦、培养正气,不担心其过度发散而损伤津液,所以谋求万全之策。
(This is Yuebi Decoction (Yuebi Tang) with four liang of Atractylodis Macrocephalae Rhizoma (Baizhu, 白术). The formula details are seen below.) It treats Li Shui (Interior Water Retention), manifesting as yellowish edema of the whole body and face, a deep pulse, and dysuria.
In cases of water qi disease, if urination occurs spontaneously, this indicates the depletion of body fluids, leading to thirst; this decoction is indicated for such conditions.
The verse states: In interior water retention, the pulse is deep, and the face and eyes appear yellow and swollen; when water and wind contend, dampness brings disaster. One specifically needs Yuebi Decoction to calm wind and water, while four liang of Baizhu excels at removing dampness.
Chen Yuanxi's commentary: When water and heat accumulate together, Qi stagnates due to dampness. This prevents Yang Qi from reaching the exterior to induce sweating and hinders the transformation of fluids in the interior to promote urination, thus resulting in water qi disease.
Some argue that for dampness, one should promote urination, which is a method of dispersing pathogenic factors from both the exterior and interior. Others suggest that Yuebi Powder removes water from the muscle layer, and adding Baizhu stops thirst and generates fluids. I argue: How can one use this decoction for patients who have spontaneous urination, depleted fluids, and thirst, without worrying about further damaging their body fluids?
(See the chapter on Dampness diseases.) It treats Feng Shui (Wind-Water Edema) characterized by a floating pulse, heavy sensation in the body, sweating, and aversion to wind; this decoction is indicated.
Chen Yuanxi's commentary: Aversion to wind indicates that wind has injured the muscle clefts (Ji Cou); a heavy sensation in the body indicates that dampness has injured the meridians; a floating pulse indicates that the disease is at the exterior level. Why not use Guizhi (Cinnamon Twig) or Mahuang (Ephedra)? Hence, Huangqi (Astragalus Root) is used instead of adhering strictly to conventional methods.
It treats Feng Shui characterized by aversion to wind, generalized edema throughout the body, a floating pulse without thirst, continuous spontaneous sweating, and absence of high fever; this decoction is indicated.
Mahuang (Ephedrae Herba, 麻黄) - six liang; Shigao (Gypsum Fibrosum, 石膏) - half jin; Shengjiang (Zingiberis Rhizoma Recens, 生姜) - three liang; Gancao (Glycyrrhizae Radix et Rhizoma, 甘草) - two liang; Dazao (Jujubae Fructus, 大枣) - twelve pieces.
Take the above five herbs, add six sheng of water, first boil Mahuang, remove the foam on the surface, then add the remaining herbs, and boil until three sheng remain. Divide into three warm doses. If there is aversion to wind, add one piece of Fuzi (Aconiti Lateralis Radix Praeparata, 附子).
The verse states: Generalized edema often belongs to wind; water surges like giant waves stirred by wind. Two parts Gancao, three parts Shengjiang, twelve Dazao, combined with eight liang of Shigao and six liang of Mahuang harmonize the formula.
Chen Yuanxi's commentary: Aversion to wind is caused by wind; generalized edema is caused by water; a floating pulse indicates the manifestation of wind. Wind is a yang pathogen; when wind moves, water and fire clash. The medication here brews into a potent force, grasping two key aspects with one approach. Furthermore, Dazao and Gancao stabilize the Middle Jiao and nourish righteous Qi, ensuring that the excessive dispersion does not damage body fluids, thereby seeking a comprehensive and safe solution.
