五劳者∶一曰肺劳，短气面浮，鼻不闻香臭；二曰肝劳，面目干黑，口苦精神不守，
能独卧，目视不明；三曰心劳，忽忽喜忘，大便苦难，或时鸭溏，口内生疮；四曰脾劳，舌
本苦直，不得咽唾；五曰肾劳，背难俯仰，小便不利，色赤黄而有余沥，茎内痛，阴囊湿生
疮，小腹满急。六极者∶一曰气极，令人内虚，五脏不足，邪气多，正气少，不欲言；二曰
血极，令人无颜色，眉发落，忽忽喜忘；三曰筋极，令人数转筋，十指爪甲皆痛苦，倦不能
久立；四曰骨极，令人瘦削，齿苦痛，手足烦疼，不可以立，不欲行动；五曰肌极，令人羸
瘦无润泽，饮食不生肌肉；六曰精极，令人少气，吸吸然内虚，五脏气不足，毛发落，悲伤
喜忘。七伤者∶一曰大饱伤脾，善噫欲卧，面黄；二曰大怒逆气伤肝，少气目暗；三曰强力
举重，久坐湿地，伤肾少精，腰背痛，厥逆下冷；四曰形寒寒饮伤肺，少气咳嗽，鼻塞，五
曰忧愁思虑伤心，苦惊喜忘喜怒；六曰风雨寒暑伤形，发肤枯夭；七曰恐惧不节伤志，恍惚
不乐。又有志劳、思劳、心劳、忧劳、瘦劳，亦名五劳。阴寒、阴痿、里急精寒精少、阴下
湿、精清、小便苦数、临事不举，亦名七伤。种种区别，愈繁愈乱，按图索骥，贻误实多，
皆非求本之论也。要之，五脏不可不分，轻重不可不辨，气血阴阳水火，不可不知，虚症之
治，无余蕴矣。若其强作解人，硬派名目，几何而不至杀人于反掌间也哉？
五劳包括：一是肺劳，表现为气短、面部浮肿，鼻子闻不到香味和臭味；二是肝劳，表现为面目干枯发黑，口苦、精神不能守舍，能够独自卧床，视力模糊不清；三是心劳，表现为心中恍惚、容易遗忘，大便干结困难，有时像鸭粪一样稀溏，口腔内生疮；四是脾劳，表现为舌根僵硬发苦，无法吞咽唾液；五是肾劳，表现为背部难以俯仰，小便不通利，颜色赤黄且有余沥不尽，阴茎内部疼痛，阴囊潮湿生疮，小腹胀满急迫。
六极包括：一是气极，使人内脏虚弱，五脏精气不足，邪气多而正气少，不想说话；二是血极，使人面色无华，眉毛头发脱落，心中恍惚、容易遗忘；三是筋极，使人频繁发生转筋（肌肉痉挛），十个手指的指甲都感到痛苦，疲倦得不能久站；四是骨极，使人身体消瘦，牙齿痛苦，手足烦热疼痛，无法站立，不想活动；五是肌极，使人瘦弱没有光泽，饮食不能转化为肌肉；六是精极，使人气短，呼吸微弱感觉内脏空虚，五脏之气不足，毛发脱落，悲伤且容易遗忘。
七伤包括：一是过饱损伤脾胃，容易打嗝想睡觉，面色发黄；二是大怒导致气机逆乱损伤肝脏，气短、视力昏暗；三是强力举重或久坐湿地，损伤肾脏导致精气减少，腰背疼痛，四肢厥冷下焦寒冷；四是形体受寒或饮用冷饮损伤肺脏，气短咳嗽，鼻塞；五是忧愁思虑损伤心脏，因惊恐而痛苦，易忘事，喜怒无常；六是风雨寒暑损伤形体，导致皮肤枯槁早衰；七是恐惧没有节制损伤意志，导致神志恍惚不快乐。
又有志劳、思劳、心劳、忧劳、瘦劳，也称为五劳。阴寒、阳痿、里急精寒精少、阴部潮湿、精液清稀、小便频数痛苦、行房时勃起功能障碍，也称为七伤。各种分类区别，越繁杂越混乱，如果按图索骥地机械套用，造成的误诊误治实在很多，这些都不是探求疾病根本的论述。总之，五脏不可不区分，病情的轻重不可不辨别，气血阴阳水火的关系不可不了解，虚损病症的治疗就没有遗漏了。如果那些强行装作懂行的人，硬要归类名目，岂不是很快就会导致杀人于反掌之间吗？
The Five Labors (Wu Lao) include: First is Lung Labor, characterized by shortness of breath, facial edema, and anosmia; second is Liver Labor, characterized with dry and dark complexion, bitter taste in the mouth, mental restlessness, ability to lie alone, and blurred vision; third is Heart Labor, characterized by mental confusion, forgetfulness, difficult or constipated stools, occasionally loose stools resembling duck feces, and oral ulcers; fourth is Spleen Labor, characterized by a stiff and bitter tongue root, and inability to swallow saliva; fifth is Kidney Labor, characterized by difficulty in bending and extending the back, dysuria, reddish-yellow urine with dribbling, pain within the penis, damp sores on the scrotum, and fullness and urgency in the lower abdomen.
The Six Extremities (Liu Ji) include: First is Qi Extremity, causing internal deficiency, insufficiency of the Zang organs, an excess of pathogenic factors, a deficiency of healthy Qi, and reluctance to speak; second is Blood Extremity, causing pallor, loss of eyebrows and hair, mental confusion, and forgetfulness; third is Tendon Extremity, causing frequent muscle spasms, pain in the fingernails, fatigue preventing prolonged standing; fourth is Bone Extremity, causing emaciation, toothache, vexing heat and pain in the hands and feet, inability to stand, and reluctance to move; fifth is Muscle Extremity, causing emaciation without luster, and food failing to transform into muscle tissue; sixth is Essence Extremity, causing shortness of breath, a sensation of internal emptiness with shallow breathing, insufficiency of Qi in the five Zang organs, hair loss, sadness, and forgetfulness.
The Seven Injuries (Qi Shang) include: First, overeating injures the Spleen, leading to belching, drowsiness, and sallow complexion; second, great anger causes Qi rebellion injuring the Liver, leading to shortness of breath and dim vision; third, strenuous lifting or sitting long on wet ground injures the Kidneys, reducing Essence, causing lower back pain, cold limbs, and coldness in the lower Jiao; fourth, external cold exposure or drinking cold beverages injures the Lungs, causing shortness of breath, cough, and nasal congestion; fifth, worry and overthinking injure the Heart, causing distress from sudden fright, forgetfulness, and emotional instability; sixth, wind, rain, cold, and heat injure the body form, causing withered skin and premature aging; seventh, unregulated fear injures the Will (Zhi), causing mental恍惚 (absent-mindedness) and unhappiness.
There are also Will Labor, Thought Labor, Heart Labor, Worry Labor, and Emaciation Labor, collectively referred to as the Five Labors. Yin-cold, impotence, interior tension with cold and scanty essence, dampness in the genital region, clear semen, painful frequency of urination, and erectile dysfunction during intercourse are collectively referred to as the Seven Injuries. Various classifications and distinctions become increasingly complex and chaotic; mechanically applying these categories leads to significant diagnostic errors, representing theories that fail to seek the root cause. Ultimately, the five Zang organs must be distinguished, the severity of conditions must be identified, and the relationships among Qi, Blood, Yin, Yang, Water, and Fire must be understood, leaving no gaps in the treatment of deficiency syndromes. If one forcibly imposes labels while pretending to understand, how could it not result in fatal consequences at a moment's notice?
