Anorexia (Inability to eat) requires differentiation between deficiency-cold and heat in the Stomach. Ershen Wan (Two Spirits Pill) and Zisheng Wan (Nourishing Life Pill) are highly effective (Ershen Wan treats cold patterns). Ning Shen San (Spirit-Calming Powder) and Zisheng Wan are also excellent (These two formulas treat deficiency-heat; above all, these are formulas for disorders of the Upper and Middle Jiao). We then discuss Yong Jun Guan for the Lower Jiao (Ershen Wan treats Kidney Fire Deficiency, Liuwei Tang (Six-Ingredient Rehmannia Decoction) treats Kidney Water Deficiency).

Gu Lao (Grain Exhaustion) is characterized by drowsiness immediately after eating, attributed to Stomach Qi deficiency where Qi fails to advance. The *Zhou Hou Bei Ji Fang* (Emergency Prescriptions Kept Up the Sleeve) records grinding Sichuan pepper, dried ginger, and barley for consumption, or using Chen Xiang Tang (Agarwood Decoction) for efficacy, which effectively alleviates symptoms.
Shi Yi (Eating Similarly/Insatiable Hunger) refers to a condition where food intake does not nourish the flesh and skin; although one eats much, it feels as if still hungry. The *Huang Di Nei Jing* states: "Heat from the Large Intestine transfers to the Stomach, causing excessive hunger and emaciation, termed Shi Yi." The Stomach is the Sea of Water and Grain, responsible for transforming food into Ying (Nutritive) and Wei (Defensive) Qi. If the Stomach is invaded by pathogenic heat, consuming the Qi of grains and failing to transform them into Essence and Blood, one experiences excessive hunger and emaciation. Furthermore, if Stomach heat transfers to the Gallbladder, it is also called Shi Yi, because the Gallbladder belongs to Yang Wood; when heat invades it, it scorches Earth (Spleen/Stomach) and accelerates digestion, making Gan Lu Yin (Sweet Dew Decoction) the appropriate treatment.

Shi Yi is caused by Stomach Heat encroaching; although appetite is good, the body becomes too thin to bear. [Metaphorical description regarding bone-thinness and Sweet Dew] allows Ying and Wei Qi to rise turbidly and ascend.

Jaundice presents with a sensation of hunger after eating, a desire to lie down, and yellowing of the whole body, face, eyes, and urine. This is due to Stomach Heat and Spleen Cold; cold generates dampness, or Wind affects the Stomach while Heat affects the Spleen, generating dampness upon exposure to cold. Internal stagnation of Damp-Heat impairs the Qi transformation of the Bladder. The Bladder governs the muscle and surface of the body; if Qi transformation fails, Damp-Heat has no outlet, resulting in Jaundice. The *Jin Gui Qian Zhu* (Light Annotation on the Golden Cabinet) discusses this in detail; here we summarize the main outline via Yin and Yang. For Yin Jaundice, the color is dark like smoked yellow, accompanied by shortness of breath and spontaneous urination; the pattern is mostly deficiency, treated with Lizhong Tang (Regulate the Middle Decoction) or Jianzhong Tang (Establish the Middle Decoction). For Yang Jaundice, the color is bright like an orange peel, accompanied by rebellious Qi and difficult urination; the pattern is mostly excess, treated with Yinyin Hao Tang (Artemisia Capillaris and Coix Seed Decoction) or Zhizi Baipi Tang (Gardenia and Phellodendron Bark Decoction). There is also a type acquired through sexual indiscretion, presenting with yellowing of the body, blackening of the forehead, slight sweating, and heat in the palms and soles, named Nü Lao Dan (Female Labor Jaundice). Take women's menstrual cloth, mix with blood, burn to ash, and take one cun cube with wine on an empty stomach, twice daily; recovery is certain within three days. However, the *Jin Gui Qian Zhu* must be read. Although this yellow manifests on the exterior, the stagnant heat is abundant internally, thus it is classified under Interior Patterns.
