凡诸郁滞，如气、血、食、痰、风、湿、寒、热，或表或里，或脏或腑，一有滞逆，皆
为之郁，当各求其属，分微甚而开之，自无不愈。气郁者，宜木香、沉香、香附、乌药、藿
香、丁香、青皮、枳壳、茴香、浓朴、抚芎、槟榔、砂仁、皂角之类。血郁者，宜桃仁、红
花、苏木、肉桂、延胡、五灵脂、牡丹皮、川芎、当归、大黄、朴硝之类。食郁者，宜山楂
、麦芽、神曲、枳实、三棱、蓬术、大蒜、萝卜，或生韭饮之类。痰郁者，宜半夏、南星、
海石、栝蒌、前胡、贝母、陈皮、白芥子、玄明粉、海藻、皂角、牛黄、天竺黄、竹沥之类
。风郁者，宜麻黄、桂枝、柴胡、升麻、干葛、紫苏、细辛、防风、荆芥、薄荷、生姜之类
。湿郁者，宜苍术、白术、茯苓、泽泻、猪苓、羌活、独活之类。寒郁者，宜干姜、肉桂、
附子、吴茱萸、荜茇、胡椒、花椒之类。热郁者，宜黄连、黄柏、黄芩、栀子、石膏、知母
、龙胆草、地骨皮、石斛、连翘、天花粉、玄参、犀角、童便、绿豆之类。以上诸郁治法，
皆所以治实邪也。若阳虚则气不能行，阴虚则血不能行，气血不行，无非郁证，若用前法
则愈虚愈郁矣，当知所辨，而参以三法如前，庶无误也。
丹溪曰∶郁病大率有六，曰∶气郁者，胸胁疼痛，脉沉而涩。湿郁者，周身走痛，或关
节疼痛，遇阴则发，脉沉而细。热郁者，瞀闷烦心，尿赤，脉沉而数。痰郁者，动则喘息，
脉沉而滑。血郁者，四肢无力，能食便血，脉沉而芤。食郁者，嗳酸腹饱，不喜饮食。或七
情之邪郁，或寒热之交侵，或九气之怫郁，或两湿之侵凌，或酒浆之积聚，故为留饮湿郁之
疾。又如热郁而成痰，痰郁而成癖，血郁而成瘕，食郁而成痞满，此必然之理也。
戴氏曰∶郁者，结聚不得发越也，当升不升，当降不降，当变化不得变化，故传化失常
而郁病作矣。大抵诸病多有兼郁者，或郁久而生病，或病久而生郁，或用药杂乱而成郁，故
凡病必参郁治。
For all types of stagnation, such as Qi (vital energy), Blood, Food, Phlegm, Wind, Dampness, Cold, and Heat, whether located in the Exterior or Interior, Zang organs or Fu organs, once there is obstruction and reversal, it constitutes a Stagnation syndrome. One should seek their respective causes, differentiate between mild and severe conditions, and apply unblocking methods; thus, recovery will invariably follow.

The above treatments for various stagnations are intended to treat excess pathogens.
However, if Yang is deficient, Qi cannot move; if Yin is deficient, Blood cannot move. When Qi and Blood fail to circulate, it manifests as stagnation. Applying the aforementioned draining methods would further deplete deficiency and exacerbate stagnation. Therefore, differentiation is essential, and one should refer to the three prior methods (tonifying Yin and Yang to facilitate movement) to avoid error.
Zhu Danxi stated: Stagnation diseases generally fall into six categories:
1. Qi Stagnation presents with pain in the chest and hypochondrium, with a deep and choppy pulse.
2. Dampness Stagnation presents with wandering pain throughout the body or joint pain, worsening on cloudy days, with a deep and fine pulse.
3. Heat Stagnation presents with dizziness, mental oppression, irritability, dark urine, and a deep and rapid pulse.
4. Phlegm Stagnation presents with panting upon exertion, with a deep and slippery pulse.
5. Blood Stagnation presents with weakness in the four limbs, ability to eat but with bloody stools, and a deep and hollow pulse.
6. Food Stagnation presents with sour belching, abdominal fullness, and loss of appetite.
These may arise from the stagnation of Seven Emotions, invasion by alternating Cold and Heat, frustration of the Nine Qi, intrusion of dual Dampness, or accumulation of wine and fluids, leading to retained fluid and dampness stagnation diseases. Furthermore, Heat Stagnation can generate Phlegm; Phlegm Stagnation can form masses (Pi); Blood Stagnation can form movable masses (Jia); and Food Stagnation can lead to epigastric fullness and obstruction (Piman). This is an inevitable logical progression.
Dai Yuanli stated: Stagnation refers to the clustering of Qi that fails to disperse. When what should ascend does not ascend, what should descend does not descend, and what should transform does not transform, the transmission and transformation functions become abnormal, resulting in stagnation diseases.
Generally, many diseases involve concurrent stagnation. Some diseases arise after prolonged stagnation; some stagnation arises after prolonged disease; and some stagnation results from chaotic medication use. Therefore, in treating any disease, one must consider the aspect of stagnation.
