【感热劳伤之症】内热躁闷，喘咳气逆，唇焦口渴，小便赤涩，此久蒸成劳，因疳成
劳之症也。

，气分感热；右脉沉数，血分感热。

【心虚劳伤之症】惊悸恍惚，神志不定，心痛咽肿，喉仲介介如梗，实则毛焦发落，
唇裂舌赤，烦热咳逆，此心劳之症也。
【心虚劳伤之因】曲运神机，耗散心血，内而欲心妄动，外而起居如惊，则诸念动处

【感热劳伤的症状】体内发热、烦躁闷乱，气喘咳嗽且气机上逆，嘴唇焦枯、口渴，小便颜色深黄且排尿涩痛。这是长期受热熏蒸导致劳损，或因疳积转化为劳损的症状。
【感热劳伤的病因】《机要》（《医学发明》，李东垣著）中说，劳损类的疾病，是因为正气虚弱而感受外邪。例如长途行走导致疲劳困倦，又逢大热天气而感到口渴，那么热邪就会留滞于肾。由于肾水不能制约心火，就会导致骨骼干枯、骨髓空虚，从而形成感热劳伤的症状。
【感热劳伤的脉象】脉象多表现为洪大且快速。左脉浮数，表示气分感受热邪；左脉沉数，表示血分感受热邪；右脉浮数，表示气分感受热邪；右脉沉数，表示血分感受热邪。
【感热劳伤的治疗】对于左脉浮数、血分感受热邪的患者，使用柴胡归芍汤，加入生地黄、牡丹皮。对于右脉浮数、气分感受热邪的患者，使用柴胡地骨皮散，加入紫苏、广陈皮来治疗。
柴胡归芍汤：治疗血分感受热邪。
药材组成：柴胡、黄芩、山栀、甘草、当归、白芍药、生地黄、牡丹皮。
柴胡地骨皮散：治疗气分感受热邪。
药材组成：柴胡、地骨皮、知母、甘草、紫苏、广陈皮、干葛。
【心虚劳伤的症状】容易受惊心悸、神志恍惚不定，心痛且咽喉肿痛，喉咙中有异物感如同被梗塞，严重时毛发焦枯脱落，嘴唇干裂、舌头红赤，烦热咳嗽气逆，这是心劳的症状。
【心虚劳伤的病因】过度用心思考，耗散了心血，内在的欲望妄动，外在的生活起居如同受惊一般，那么在念头萌动的地方都会产生火邪。火邪旺盛损伤肺金（肺属金），导致咳嗽气急，于是心劳的症状就发作了。
【心虚劳伤的脉象】左脉多呈现浮象。左寸脉浮缓，表示心气不足；左寸脉浮数，表示心血不足。
【心虚劳伤的治疗】心气不足，属于虚寒证的，使用归脾汤；属于虚热证的，使用天王补心丹。心血不足，属于虚热证的，使用门冬安神丸；属于实热证的，使用导赤各半汤。
[Symptoms of Heat-Induced Labor Injury] Internal heat, restlessness, and oppression; panting, coughing, and rebellious qi; dry and cracked lips with thirst; dark and scanty or painful urination. These are symptoms of labor injury caused by long-term steaming from heat, or labor injury resulting from gan (nutritional deficiency syndrome in children).
[Etiology of Heat-Induced Labor Injury] The *Jiyao* (Essential Principles) states that diseases of labor damage arise from deficiency leading to pathogenic invasion. For instance, fatigue from long-distance travel combined with thirst induced by extreme heat causes heat to lodge in the Kidney. When Kidney Water fails to control Heart Fire, it results in dry bones and empty marrow, thereby forming the condition of heat-induced labor injury.
[Pulse Patterns of Heat-Induced Labor Injury] The pulse is often surging (Hong) and rapid (Shu). A floating and rapid pulse on the left indicates heat in the Qi level; a deep and rapid pulse on the left indicates heat in the Blood level. A floating and rapid pulse on the right indicates heat in the Qi level; a deep and rapid pulse on the right indicates heat in the Blood level.
[Therapeutic Methods for Heat-Induced Labor Injury] For patients with a floating and rapid pulse on the left, indicating heat in the Blood level, use Chaihu Guishao Tang (Bupleurum and Peony Decoction) with added Shengdi Huang (Rehmanniae Radix) and Dan Pi (Moutan Cortex). For patients with a floating and rapid pulse on the right, indicating heat in the Qi level, use Chaihu Digupi San (Bupleurum and Phellodendron Powder) with added Zi Su (Perilla Leaf) and Guang Pi (Citri Reticulatae Pericarpium).
Chaihu Guishao Tang: Treats heat in the Blood level.
Ingredients: Chai Hu (Bupleuri Radix), Huang Qin (Scutellariae Radix), Shan Zhi (Gardeniae Fructus), Gan Cao (Glycyrrhizae Radix et Rhizoma), Dang Gui (Angelicae Sinensis Radix), Bai Shao Yao (Paeoniae Radix Alba), Sheng Di Huang (Rehmanniae Radix), Dan Pi (Moutan Cortex).
Chaihu Digupi San: Treats heat in the Qi level.
Ingredients: Chai Hu (Bupleuri Radix), Di Gu Pi (Lycii Cortex), Zhi Mu (Anemarrhenae Rhizoma), Gan Cao (Glycyrrhizae Radix et Rhizoma), Zi Su (Perillae Folium), Guang Pi (Citri Reticulatae Pericarpium), Gan Ge (Puerariae Radix).
[Symptoms of Heart Deficiency Labor Injury] Palpitations due to fright, mental confusion and instability, heart pain, and throat swelling. There is a sensation of obstruction in the throat as if something were stuck. In severe cases, hair becomes brittle and falls out, lips crack, and the tongue is red. Accompanied by irritability, heat, coughing, and rebellious qi, these constitute the symptoms of heart labor injury.
[Etiology of Heart Deficiency Labor Injury] Excessive mental exertion dissipates Heart Blood. Internally, desires move recklessly; externally, daily activities resemble a state of fright. Wherever thoughts arise, fire is generated. Excessive fire damages Metal (the Lung), causing coughing and急促 breathing, thus triggering heart labor injury.
[Pulse Patterns of Heart Deficiency Labor Injury] The left pulse is often floating. A floating and moderate (Huan) pulse at the left Cun position indicates insufficient Heart Qi; a floating and rapid (Shu) pulse at the left Cun position indicates insufficient Heart Blood.
[Therapeutic Methods for Heart Deficiency Labor Injury] For insufficient Heart Qi presenting as deficiency-cold, use Guipi Tang (Restore the Spleen Decoction); for deficiency-heat, use Tianwang Buxin Dan (Emperor of Heaven's Special Pill to Nourish the Heart). For insufficient Heart Blood presenting as deficiency-heat, use Mendong Anshen Wan (Ophiopogon Pill to Calm the Spirit); for excess-heat, use Daochi Geban Tang (Half-and-Half Decoction for Directing Redness).

Tianwang Buxin Dan: See previous section on cough with epistaxis/hemoptysis.
