阳无所根据，遂致浮散于肌表之间。虽有恶热之状，诚阴虚证也，脉必细数，治宜滋阴。

The *Yellow Emperor's Inner Canon* states: Yin deficiency generates internal heat; Yang resides on the exterior, serving as the defense of Yin; Yin resides within, serving as the guardian of Yang. Excessive sexual activity damages the True Yin (Zhen Yin). Once Yin Qi is deficient, Yang has no foundation to rely upon, causing it to float and scatter between the muscle and skin layers. Although there are symptoms of aversion to heat, this is indeed a syndrome of Yin deficiency. The pulse will necessarily be fine and rapid; treatment should focus on nourishing Yin.
Main Formula: Dang Gui (Radix Angelicae Sinensis), Bai Shao Yao (Radix Paeoniae Alba), Sheng Di Huang (Radix Rehmanniae Preparata), Zhi Mu (Rhizoma Anemarrhenae), Mai Men Dong (Tuber Ophiopogonis), Bai Zhu (Rhizoma Atractylodis Macrocephalae), Bai Fu Ling (Poria) [all in equal parts]; Chai Hu (Radix Bupleuri), Gan Cao (Radix Glycyrrhizae) [dosage halved]. Decoct with Sheng Jiang (Rhizoma Zingiberis Recens) and Da Zao (Fructus Jujubae) and take orally.
(Attachment: Big Head Plague [Da Tou Wen], Mumps-like Plague [Xia Ma Wen])
The Yellow Emperor asked: There is a type of plague patient who sweats and then immediately fevers again, with a restless and rapid pulse that does not subside due to sweating, accompanied by delirious speech and inability to eat. What is this disease called? Qibo replied: This disease is named "Yin-Yang Intersection" (Yin Yang Jiao). Diseases of Yin-Yang intersection are fatal and incurable (This refers to the intermingling of Yin and Yang, where Qi and Blood do not follow their proper courses, leading to chaotic meridian flow and fever, thus the fever does not cease. It means that after taking medicine and sweating, the fever does not resolve, and the restless pulse indicates an incurable condition.) It is also said: If one is injured by Cold in winter, one will inevitably suffer from Warm diseases in spring. Therefore, the occurrence of Warm Epidemics should be deduced from the influence of the Six Qi (Yun Qi). Mildness in Spring, Heat in Summer, Coolness in Autumn, and Cold in Winter constitute the normal Qi of the four seasons. Deviations from these are abnormal Qi; contracting them causes disease. For example, severe cold in winter, if encountered, leads to Cold Damage (Shang Han). Cold toxicity hides in the skin and muscles, transforming into Warm disease in Spring and Heat disease in Summer. Or, if there is unseasonable warmth in winter, contracting it leads to Winter Warmth (Dong Wen). If many people contract the same illness, it is called Heavenly Flow Seasonal Epidemic (Tian Xing Shi Yi). If within a year, the solar terms are disordered, cold and heat are abnormal, and accompanied by heavy rain, fierce winds, or lingering fog and dew, the people will suffer from Plagues. Regardless of age, the symptoms are generally similar, hence it is called Plague Li Disease. This is what is meant by "If one does not store Essence in winter, one will suffer from Warm disease in spring." A gentleman keeps his essence secure and is not harmed by Cold; a wise person is cautious, so even strong winds and harsh toxins cannot harm him. The transmission and treatment of these diseases are largely similar to those of Cold Damage, and methods from Cold Damage can be used for reference. For releasing the exterior, mild acrid agents should be used; hot drugs like Ma Huang (Ephedrae Herba) should not be used. Pulse diagnosis: Taiyang disease presents with a large pulse; Yangming disease with a string-taut and long pulse; Shaoyang disease with a string-taut and rapid pulse; Taiyin disease with a fine and string-taut pulse; Shaoyin disease with a deep and fine pulse; Jueyin disease with a slightly moderate pulse.
