《病机机要》云∶“中腑者，宜汗之，中脏者，宜下之。”此腑脏二字，实是指经络，言腑无汗法，入脏亦岂有下法？
“五脏者，藏精气而不写，故满而不能实；六腑者，传化物而不藏，故实而不能满。”此脏宜补，腑宜通之要旨也。考
长沙三百九十七法，邪归中土，乃可议下，其少阴急下三条，指转入阳明腑证者言，仍是土郁夺之之义，如已脏真失守，
而复泻之，是虚虚也。古于汗下之法，禁例綦严，岂宜如是之倒行逆施乎？观其论中腑曰脉浮恶风寒，则明是中经；论
中脏曰大便秘结，则明是中腑。辨名正误，庶于立言之旨有合云。

《病机机要》中说：“中腑的病证，适宜用发汗法治疗；中脏的病证，适宜用泻下法治疗。”这里的“腑”和“脏”二字，实际上是指经络而言。如果说腑病没有发汗的治法，那么邪气入脏难道就有泻下的治法吗？
《黄帝内经》说：“五脏的功能是贮藏精气而不向外泄泻，所以它们的状态是充满精气但不能被水谷实邪填满；六腑的功能是传导消化后的糟粕而不贮藏精气，所以它们的状态是可以被水谷实邪填满但不能保持精气的充盈。”这是说明脏宜补益、腑宜通利的关键要点。考察张仲景（长沙太守）所立的三百九十七种治法，只有当邪气传入中土（脾胃/阳明），才可以讨论使用泻下法。其中少阴病急下证的三条条文，指的是邪气转入阳明腑实证的情况，这仍然符合“土郁夺之”（通过泻下解除中焦郁滞）的意义。如果脏腑的真气已经失守，再使用泻下法，这就造成了“虚虚”（使虚者更虚）的错误。古人对于发汗和泻下法的禁忌规定非常严格，怎么能像这样颠倒行事、违背常理呢？观察原文论述中腑时说“脉浮、恶风寒”，这明确是指中经（经络受邪）；论述中脏时说“大便秘结”，这明确是指中腑（腑气不通）。辨别名称以纠正错误，才符合立论的本意。
按周天运行共三百六十五度又四分之一度，其间日月星辰循环流转而不停息，依靠南北两极作为枢纽。两极安居其位，众星环绕拱卫它，星星在运动而极星不动，体现了动以静为主的原则。《灵枢·五十营篇》说：人体的经脉上下、左右、前后共二十八条，对应天上的二十八宿。一呼气时气行三寸，一吸气时气行三寸，经过一万三千五百次呼吸，气在体内运行五十个周次，水下漏百刻，太阳运行二十八宿的距离，此时漏水滴尽，经脉之气也运行完毕了。人的营气和卫气营运不息，如果没有一个根本来统摄，怎么可能经常循环不休止呢？心主与命门，就是人身上的南极和北极。心，是神志居住的处所，神藏于内不显露且处于无为状态，五脏六腑的营运，无不以心为君主，所以《内经》说“君主清明则下属安宁，君主昏昧则十二官危”。心的元神，就是天上的南极。命门的一点元气，是生气的根源，藏在两肾中间，作为十二经脉的根本，必须像锁钥一样闭固，正如《内经》所说“阴气平和，阳气秘固，精气才能正常治理”。肾的元气，就是天上的北极。天的南极，潜入地下三十六度，位于南方，下方属阴而南方属阳，是居于阴位的阳。人的心君位于腹部之上，腹部属阴而上方属阳，也是居于阴位的阳。天的北极，露出地面三十六度，位于北方，上方属阳而北方属阴，是居于阳位的阴。人的命门，位于背部之下，背部属阳而下方属阴，也是居于阳位的阴。天的两个极，相对而立作为中枢，然后营运不息；人的心君与命门，也必须神气相合，然后营卫才能周流不息。然而静，是动的根基。心作为十二官的君主，主导静定；命门作为十二经脉的根本，主导秘密固藏，这就是两极安居其位而不移动的道理。
The *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet) states: "For diseases affecting the Fu organs, sweating methods are appropriate; for diseases affecting the Zang organs, purgative methods are appropriate." The terms "Fu" and "Zang" here actually refer to the meridians. If it is said that there is no sweating method for Fu organ diseases, how could there be a purgative method for pathogens entering the Zang organs?
The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: "The five Zang organs store essence and qi without excreting, thus they are full but not solid; the six Fu organs transmit and transform substances without storing, thus they are solid but not full." This is the key principle that Zang organs should be tonified and Fu organs should be unblocked. Examining the three hundred and ninety-seven treatment methods established by Zhang Zhongjing (the Grand Administrator of Changsha), purgation can only be considered when the pathogen enters the central earth (Spleen/Stomach or Yangming). The three clauses regarding urgent purgation in Shaoyin disease refer to cases where the pathogen has transferred to the Yangming Fu organ syndrome, which still aligns with the meaning of "attacking the stagnation of earth" (resolving middle-jiao stagnation via purgation). If the true qi of the Zang organs has already been lost, administering purgatives would constitute "making the deficient more deficient" (exacerbating deficiency). Ancient texts were extremely strict regarding contraindications for sweating and purging methods; how could one act so contrary to reason? Observing the discussion on "diseases affecting the Fu," it mentions "floating pulse, aversion to wind and cold," which clearly indicates "diseases affecting the meridians" (pathogens in the collaterals); discussing "diseases affecting the Zang," it mentions "constipation," which clearly indicates "diseases affecting the Fu organs" (obstruction of Fu organ qi). Distinguishing names to correct errors would better align with the original intent of the discourse.
According to the celestial sphere, there are 365 and 1/4 degrees. The continuous circulation of the sun, moon, and stars relies on the North and South Poles as pivots. The two poles remain stationary while all other stars revolve around them; the stars move, but the poles do not, demonstrating that motion is governed by stillness. The *Lingshu: Fifty Circulations Chapter* states: "The human body has twenty-eight meridians running up, down, left, right, front, and back, corresponding to the Twenty-Eight Lunar Mansions. With each exhalation, Qi moves three cun; with each inhalation, Qi moves three cun. After thirteen thousand five hundred breaths, Qi completes fifty circuits in the body, water drains from the clepsydra for one hundred marks, and the sun travels the distance of the Twenty-Eight Lunar Mansitions. When the water runs out, the meridian Qi also ends." The circulation of Ying (Nutritive) and Wei (Defensive) Qi cannot ceaselessly cycle without a fundamental controller. The Heart Master and the Mingmen (Gate of Life) serve as the South and North Poles of the human body. The Heart is the residence of Shen (Spirit); Shen resides within, remains concealed, and acts through non-action. The operations of the five Zang and six Fu organs are all directed by the Heart as the sovereign. Thus, the Classics state: "If the Sovereign is clear-minded, the subordinates are at peace; if the Sovereign is unclear, the twelve officials are in danger." The primordial Shen of the Heart corresponds to the Celestial South Pole. A single point of Yuan Qi (Original Qi) in the Mingmen is the root of vital energy, hidden between the two Kidneys, serving as the foundation of the twelve meridians. It must be securely locked like a gate latch, as stated in the Classics: "When Yin is peaceful and Yang is secure, Jing and Qi are regulated." The Yuan Qi of the Kidney corresponds to the Celestial North Pole. The Celestial South Pole dips thirty-six degrees below the horizon and is positioned in the south; below is Yin and south is Yang, representing Yang residing in a Yin position. The Human Heart Sovereign is located above the abdomen; the abdomen is Yin and above is Yang, also representing Yang residing in a Yin position. The Celestial North Pole rises thirty-six degrees above the horizon and is positioned in the north; above is Yang and north is Yin, representing Yin residing in a Yang position. The Human Mingmen is located below the back; the back is Yang and below is Yin, also representing Yin residing in a Yang position. The two celestial poles stand opposite each other as the central pivot, enabling endless circulation; similarly, the Human Heart Sovereign and Mingmen must have their Shen and Qi combined to allow Ying and Wei Qi to circulate endlessly. However, stillness is the root of motion. As the sovereign of the twelve officials, the Heart governs stillness and stability; as the foundation of the twelve meridians, the Mingmen governs secrecy and retention. This is analogous to the two poles remaining stationary in their positions.
