六阳六阴脉，分属左右手。心、小肠、肝、胆、肾、膀胱在左，主血；肺、大肠、脾、胃、命门、三焦在右，主气。

六阳脉与六阴脉，分别归属于左右两手。左手候心、小肠、肝、胆、肾、膀胱，主血；右手候肺、大肠、脾、胃、命门、三焦，主气。
男子以气为基础受孕，所以气为主宰；女子以血为基础受孕，所以血为主宰。如果男子久病，右手寸口脉（气口）的搏动强于左手人迎脉，说明还有胃气，病情虽然严重也可以治疗；女子久病，左手人迎脉的搏动强于右手寸口脉（气口），说明还有胃气，病情虽然严重也可以治疗。与此相反的情况属于逆证。有人问：人迎脉在左手，气口脉在右手，男女都是如此，位置固定不变。脉法说：左手脉大顺合男性生理，右手脉大顺合女性生理，为什么您的说法违背常理呢？我说：《脉经》全书，王叔和谆谆教导医者，这里的左右手是以医生诊脉时的站位为基准而言的，如果以患者为本位，那错误就相差千里了！
春，意为蠢动。阳气升浮，草木萌芽，蠢然而动。前代哲人说春季人体人气在头部，有病适宜用吐法。又说：治疗伤寒的大法，春季适宜用吐法。“宣”的意思就是扬举。所谓吐法，是从上部排出的方法。现在的世俗之人，往往有疮疡的人，胸膈胀满的人，虫积的人，认为不在春季用毒药进行宣泻就不能痊愈。医生于是用牵牛子、巴豆、大黄、枳壳、防风等药制成丸剂，命名为春宣丸。在二月、三月服用，直到出现腹泻才停止。在刚开始腹泻的时候，脏腑得以通畅，暂时感觉轻松爽快。却不知道气机升发于上，则下部的阴气非常虚弱，而使用泻下药残害其阴气，这种危害哪里说得完呢！况且张仲景使用承气汤等泻下药，必须有严重的痞满、坚实的实证，有燥屎内结，转矢气，腹部下迫急迫且没有表证的情况下，才施行这种方法。可下的证候不完全具备时，还需要等待时机。泻利性质的药物，怎么可以轻易尝试呢？
我的伯父身体肥胖但骨骼消瘦，口味浓重性格深沉，五十岁时轻信他人，忽然在三月半购买春宣丸一帖，服用后腹泻两三次。每年都以此为常规。到了五十三岁那年，七月初天气炎热至极，无病突然死亡。这难道不是错误地把春宣当作春泻，从而招致祸患吗？从上向下召唤称为“宣”，“宣”这个字，明确是指吐法。张子和先生已经详细论述过，前代贤人怎么会乱说话呢！经过详细审查订正，毫无疑问。后来因此死亡的又有几个人，我特意列举出来，作为后人的警戒！
The six Yang pulses and the six Yin pulses are distributed to the left and right hands respectively. The Heart, Small Intestine, Liver, Gallbladder, Kidney, and Bladder are on the left, governing Blood; the Lung, Large Intestine, Spleen, Stomach, Mingmen (Gate of Life), and Sanjiao (Triple Burner) are on the right, governing Qi.
Men conceive through Qi, so Qi is primary; women conceive through Blood, so Blood is primary. If a man has been ill for a long time and the Qikou pulse (Cunkou pulse at the right wrist) is fuller than the Yingying pulse (Renying pulse at the left carotid artery), it indicates the presence of Stomach Qi; although the illness is severe, it is treatable. If a woman has been ill for a long time and the Yingying pulse is fuller than the Qikou pulse, it indicates the presence of Stomach Qi; although the illness is severe, it is treatable. The reverse situation is considered adverse (Ni). Someone might ask: "The Yingying pulse is on the left, and the Qikou pulse is on the right; this is the same for both men and women, with fixed positions. The Pulse Classic states: 'A large pulse on the left suits men, a large pulse on the right suits women.' Why does your statement contradict this?" I reply: "In the entire *Mai Jing* (Pulse Classic), Wang Shuhe earnestly instructs physicians that these left and right hands refer to the physician's position during diagnosis. If interpreted from the patient's perspective, the error would be as vast as a thousand miles!"
Spring implies stirring or awakening. Yang Qi ascends and floats, grasses and trees sprout, stirring into motion. Ancient sages stated that in spring, human Qi resides in the head, and illnesses should be treated with emesis (Tui Fa). It is also said: "The general principle for treating Shanghan (Cold Damage) is to use emesis in spring." The term "Xuan" means to raise or spread. Emesis is described as a method where pathogens exit from the upper body. In contemporary secular practice, people often believe that those with skin sores, chest fullness, or intestinal parasites cannot recover unless they undergo purgation with toxic herbs in spring. Physicians therefore prepare pills using Qian Niu Zi (Pharbitidis Semen), Ba Dou (Crotonis Fructus), Da Huang (Rhei Radix et Rhizoma), Zhi Ke (Aurantii Fructus Immaturus), Fang Feng (Saposhnikoviae Radix), etc., naming them Chun Xuan Wan (Spring Spreading Pill). These are taken in February and March until diarrhea occurs. At the onset of diarrhea, the Zang-Fu organs become unblocked, providing temporary relief. However, one fails to realize that when Qi rises to the upper body, the Yin in the lower body becomes extremely weak. Using purgative drugs damages this Yin, a harm too numerous to describe. Moreover, Zhang Zhongjing used Xia Yao (purgative formulas) like Chengqi Tang only when there was severe fullness, solid excess, dry feces, passing flatus, abdominal urgency, and no exterior syndrome. If the indications for purgation are not fully present, one must wait. How can purgative drugs be tried lightly?
My uncle had a fat body but thin bones, favored strong flavors, and had a deep temperament. At fifty years old, he轻信 (lightly believed others) and suddenly bought a dose of Chun Xuan Wan in mid-March, taking it which resulted in two or three bowel movements. He made this a yearly routine. In his fifty-third year, in early July when the heat was intense, he died suddenly without prior illness. Was this not due to mistakenly treating Chun Xuan as a spring purge, thereby bringing disaster upon himself? To summon from above is called "Xuan"; thus, "Xuan" clearly refers to emesis. Mr. Zhang Hezi has already discussed this in detail; how could ancient sages speak falsely? After careful examination and verification, there is no doubt. Several others have since died from this practice. I highlight this case as a warning for future generations!
