Ms. Shi has suffered from a pathogenic sensation syndrome for over three weeks (21 days). Initially, chills and fever were mixed and indistinguishable; subsequently, she experienced fever without chills, with heat intensifying in the late afternoon (Shi Wu) and gradually subsiding at dawn. Reviewing previous prescriptions, Xiaoyao San (Free and Easy Wanderer Powder) was administered first, followed by Taoren Chengqi Tang (Peach Kernel and Rhubarb Decoction), yet the condition worsened with each treatment. She had poor appetite, loose stools, swollen feet, and abdominal distension; the severity of distension correlated with the degree of fever—worse when hot, better when cool. If this were Liver Qi stagnation, fever would not necessarily occur, nor would distension fluctuate with heat. If this were Blood Bi (Blood Stasis Obstruction), the pathology should be in the Lower Jiao (Lower Burner), not manifesting as distension in the Middle Wan (Epigastrium). Investigating the etiology, it is not due to Qi stagnation or Blood coagulation, but rather the lingering of latent pathogens. *Jiren Bian* states: "Late-onset sensations in autumn, resembling malaria, are essentially diseases of latent Summerheat. Summerheat invariably carries Dampness, lodging in the Mo Yuan (Membrane Source), which corresponds to the Middle Jiao. After long-term latent residence, the pathogen erupts according to timing. Moving from interior to exterior, this results in external heat and internal distension. Regarding loose stools and foot swelling, these undoubtedly belong to Dampness diseases." To eliminate distension, one must dispel the pathogen. As long as the pathogen remains, distension persists. This illustrates the principle that Shanghan (Cold Damage) requires differentiation of the Six Channels, while Wenbing (Warm Diseases) and Summerheat require differentiation of the Three Jiaos. If the Upper Jiao is not resolved, the disease will inevitably spread; for the Middle and Lower Jiao, mild diuresis (Dan Shen) combined with slightly acrid herbs is used. This is because formless pathogens cannot be attacked as if they were tangible excesses. The previous proposal suggested that sweating after medication, leading to reduced fever and distension, indicates the mechanism of latent pathogens reaching the exterior. Latent Summerheat-Damp pathogens differ from Wind-Cold exterior pathogens; new exterior pathogens should first be cleared via the exterior, whereas latent pathogens should first be cleared from the interior. Once the interior is clear, the exterior resolves spontaneously. Recently, cough has appeared, and diarrhea persists. In exterior diseases, cough is considered mild; in Fu organ diseases, unblocking constitutes tonification. Both cough and diarrhea serve as outlets for latent pathogens and should not be forcibly suppressed.

An Bo notes: Prescribed Bohe (Mint) and Shanzhi (Gardenia Fruit), using bitter and acrid flavors to clear interior heat; Fuling Pi (Poria Peel), Dadou Juan (Soybean Sprout), Huashi (Talcum), and Tongcao (Akebia Stem), using sweet and bland flavors to leach out exterior dampness; Xingren (Apricot Seed) and Juhong (Citrus Reticulata Pericarpium) to open Lung Qi; Banxia (Pinellia Tuber) and Peilan (Eupatorium Fortunei) to awaken the Spleen.

At age fourteen (two sevens), Tian Gui (menstrual essence/substance promoting reproductive maturity) arrives, the Ren Mai (Conception Vessel) becomes unobstructed, and the Chong Mai (Penetrating Vessel) becomes abundant, causing menstruation to arrive on time; hence it is called Menstruation (Jing). "Jing" means regularity; deviation from regularity constitutes disease. Therefore, regulating menstruation is paramount for women; if regulated, hundred diseases do not arise; if disregulated, various symptoms swarm forth. Blood is generated by the Heart, stored in the Liver, and controlled by the Spleen. The Chong Mai is the Sea of Blood; blood is like water. Just as rivers flow, if they dry up or burst their banks, the disaster is great. Investigating the causes of illness, some attribute it to Blood depletion. Generally, women regard the Liver as their先天 (primary foundation); they are prone to depression. Liver Wood stagnation generates Fire, which scorches Yin and damages fluids, causing menstrual blood to deplete daily and the menstrual pathway to become obstructed. The Classics state: "Diseases of the Two Yang (Stomach and Large Intestine) originate from the Heart and Spleen; those with hidden grievances who do not menstruate exemplify this." Others attribute it to Bing Jue (Metrorrhagia and Metrostaxis). "Bing" is like the collapse of a mountain peak; "Jue" is like waves bursting forth. Since Blood belongs to Yin, when quiet, it circulates within the vessels; when agitated, it flows erratically. The Classics state: "Yin deficiency with Yang pulsation is termed Bing." When Yang Qi moves internally, it causes Xin Xia Beng (subcutaneous bleeding/menstrual flooding); this exemplifies such cases. Having been ill for a long time, her physique is emaciated and Yin is deficient, with Liver Fire stagnant and vigorous. Last spring, she experienced amenorrhea, metrorrhagia, and syncope; now her period is delayed by two months. Do not worry about the lack of blood flow; rather, fear the recurrence of metrorrhagia. The proposed treatment is to nourish Kidney Yin to assist Heart Yang, while simultaneously cultivating the Chong and Ren vessels, hoping for continuous vitality, balanced Qi and Blood, no risk of erratic flow, and restoration of normal cycles. Not only will the disease depart and the person be safe, but health may return even without medication.

An Bo notes: Prescribed self-made Bulian Wan (Nourishing Refining Pill) to nourish Kidney Yin and assist Heart Yang, and to cultivate the Chong and Ren vessels to support their functions.
