According to the *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet): It states that Baihe Bing (Lily Disease) occurs because all meridians share a single origin (the Heart), leading to pathological involvement of all meridians. The patient desires to eat but cannot; remains often silent; desires to lie down but cannot sleep; desires to walk but cannot move. Food may sometimes taste good, or at other times the patient may dislike the smell of food. They feel as if cold but are not actually cold, and feel as if hot but are not actually hot. There is bitter taste in the mouth and dark red urine. Various medicines cannot cure it; taking medicine causes severe vomiting and diarrhea, as if possessed by spirits. The physical appearance seems normal, but the pulse is slightly rapid. If headache occurs during urination, recovery takes sixty days; if there is no headache during urination but rather a sensation of chilliness, recovery takes forty days; if urination feels comfortable but with dizziness, recovery takes twenty days. This disease may manifest symptoms before the illness fully develops, or appear four to five days after onset, or twenty days later, or even a month later with mild symptoms. Treatment should follow the specific syndrome presentation.

For Baihe Bing treated with sweating methods, Baihe Zhi Mu Tang (Lily and Anemone Decoction) is the primary prescription. For Baihe Bing treated with purgation methods, Huashi Daizhe Tang (Talcum and Hematite Decoction) is used. For Baihe Bing treated with emetic methods, Baihe Jizi Tang (Lily and Egg Yolk Decoction) is indicated. For Baihe Bing not treated with emetics, purgatives, or sweating methods, where the condition remains unchanged, Baihe Dihuang Tang (Lily and Rehmannia Decoction) is the main treatment. If Baihe Bing persists for a month and transforms into thirst, Baihe Xi Fang (Lily Bathing Prescription) is used. If thirst persists after bathing, Gualou Muli San (Trichosanthes Root and Oyster Shell Powder) is administered. If fever develops, Baihe Huashi San (Lily and Talcum Powder) is prescribed. For Baihe Bing presenting with Yin syndromes, Yang-rescuing methods are used; for Yang syndromes, Yin-rescuing methods are applied. Attacking Yin when Yang signs are present, followed by sweating, is a contraindication (Ni). Attacking Yang when Yin signs are present, followed by purgation, is also a contraindication.

The phrase "all meridians share a single origin" refers to the fact that all blood in the body is governed by the Heart. The Heart governs blood vessels and is associated with Fire. If Fire pathogen is excessive, heat accumulates and does not dissipate, flowing into the blood vessels, thus causing all meridians to be affected. Qi belongs to Yang, and Blood belongs to Yin. Excess Qi leads to heat, while deficient Qi leads to cold. Since the pathology is in the Blood aspect and does not involve Qi, the patient feels neither truly cold nor truly hot. The inability to eat, sleep, or walk despite the desire to do so reflects the scorching of Yin by Yang-Fire, a state of helplessness. Upper heat causes bitter taste, and lower heat causes dark urine, both resulting from Yang-Fire damaging Yin. Although medicines treat diseases, they must rely on Stomach-Qi to circulate. If toxic blood stasis blocks the Spleen and Stomach and closes the meridians, the medicine enters but the weak Stomach-Qi cannot propel it, causing the condition to worsen with vomiting and diarrhea after administration. Since the disease is not in the skin, flesh, sinews, or bones, the body shape appears normal. Only heat in the blood causes the slightly rapid pulse. A rapid pulse indicates blood heat; Heart-Fire flares upward without descending to communicate with the Kidney, and the Bladder meridian fails to guide essence upward. Upper deficiency leads to dizziness during urination, and severely, headache. Based on the severity, one can predict the time to recovery. All treatments use Baihe (Lily Bulb) as the sovereign herb to calm the Heart and nourish the Spirit, clearing heat from the blood and promoting urination and defecation to drain stagnation. Fresh Baihe is essential for efficacy. If caused by improper sweating, add Zhi Mu (Anemone Root) to regulate upper Jiao fluids. If caused by improper purgation, add Huashi (Talcum) and Daizheshi (Hematite) to resolve lower Jiao obstruction. If caused by improper emesis, add Jizi Huang (Egg Yolk) to nourish middle Jiao Ying-Blood. If not treated with emesis, purgation, or sweating, simply add Sheng Dihuang (Fresh Rehmannia Juice) to cool the blood; cooling the blood resolves heat-toxins and allows accumulation to pass naturally, resulting in black, lacquer-like stool. If unresolved after a month, with blocked meridians and failure to transform fluids causing thirst, bathing with Baihe opens the meridians and restores fluid flow, stopping thirst. Do not consume salt or Chi (Fermented Soybeans), as salty flavors congeal blood. If thirst persists after bathing due to lack of middle Jiao fluids, use Gualou (Trichosanthes Root) and Muli (Oyster Shell). If fever develops due to meridian stagnation, add Huashi (Talcum) to promote free flow. Baihe Bing exists between exterior and interior, not strictly in either, as heat travels within the blood vessels, unlike Shanghan (Cold Damage) which can be treated with sweating or purging. Thus, misdiagnosis is common, and the disease may linger for years. Recovery dates are no longer fixed. Regarding rescue from complications due to improper sweating/purging, the general principles above apply, adjusted for the patient's constitutional deficiency or excess. One must not mistake lower Yuan deficiency for the indication and use warming tonification. Note: Baihe Bing is essentially an acute form of Wei Zheng (Flaccidity Syndrome). Acquired after Shanghan, it is called Baihe Bing; acquired from chronic Lung disease, it is called Wei Zheng.

Shi Wan treated the mother of Hanlin Academician Meng Duan Shi. Because Meng served in the Hanlin Academy, he neglected regular filial visits, and reports indicated slight discomfort. Deficient fire rose intermittently, causing spontaneous sweating, mental restlessness, difficulty eating, insomnia, bitter taste, difficult urination, and dizziness/chilliness during urination. From last year until then, various physicians were consulted; each medication added new symptoms. Baizhu (Atractylodes Rhizome) caused bloating; Chuanpi (Citrus Peel) caused palpitations and panting; Yuanzhi (Polygala Root) caused irritability and heat; Muxiang (Aucklandia Root) caused abdominal heat and dry throat; Renshen (Ginseng Root) caused confusion and anorexia; Zhike (Immature Bitter Orange) caused cough and shortness of breath; Maidong (Ophiopogon Tuber) caused urinary incontinence; Rougui (Cinnamon Bark) caused cranial distension and cough; Buguzhi (Psoralea Fruit) caused tenesmus and dryness; Zhimu (Anemone Rhizome) and Huangbai (Phellodendron Bark) caused empty lower abdomen; Huangqin (Scutellaria Root) and Zhizi (Gardenia Fruit) caused umbilical tightness; Xiangru (Elsholtzia Herb) caused tinnitus and vertigo; the patient constantly needed support to walk; Dahuang (Rhubarb Root) caused umbilical throbbing and lower abdominal contraction. Consequently, the patient feared medicine like scorpions, relying only on 1 qian of Renshen daily mixed in porridge to sustain life. In spring, deficient fire intensified; upon rising, profuse whole-body sweating occurred, nearly depleting Shen-Qi. Only deep fatigue with little sleep prevented sweating and calmed the mind. Shortly after waking, fire rose again, bringing sweat, distinct from Dao Han (Night Sweats). By mid-second lunar month, Shi Wan was invited to diagnose. The pulse was slightly rapid; the Left Chi and Left Cun positions were significantly stronger than others; the Qi Kou position felt faint. After diagnosis, the patient recounted previous illnesses and worsening due to medications. Many famous doctors in Wu region could not identify the disease. Shi Wan stated: "This originates from long-term overthinking injuring the Spleen, trapping Spleen-Yin, causing Jue-Yang Fire to gather in the Heart, disturbing the hundred meridians. The disease name is Baihe. Zhang Zhongjing's *Jin Gui Yao Lue* details this extensively. The text states 'various medicines cannot cure it,' hence each drug adds symptoms. Only Baihe Dihuang Tang is the specific remedy. However, chronic illness has depleted Middle Qi, and iatrogenic errors have created complex complications. Initially, use Sheng Mai San (Generate the Pulse Powder) plus Baihe, Fushen (Poria with Hostwood), and Longchi (Dragon Bone) to calm the Spirit, with少量 ShanYuzhu (Cornus Fruit) and Huanglian (Coptis Rhizome) to curb the fire. After several doses stabilize, stop all herbs to nourish Stomach-Qi, using only fresh Baihe decoction daily. As autumn arrives, Heaven's Qi descends, fire subdues, and safety is ensured. Later, in mid-autumn, Meng returned home and recovered happily without medication. Subsequently, due to mental labor, fire rose again. Zuojin Wan (Assist the Metal Pill) was prescribed successfully. Thereafter, whenever slight fire flare-ups occurred, this pill was taken. However, the bitter-dry nature enters the Heart first, and pungent-salty flavors enter the Liver. Long-term use risks transforming into fire. Must one not consider this balance proactively?"
