When Taiyin (Too Yin) governs the heaven, if Cold-Water qi prevails excessively, Heart-Fire becomes constrained internally. If internal heat is already severe, treating internal heat should be the urgent priority; if internal heat is not yet severe, dispelling cold and resolving constraint should be the urgent priority. For instance, in *Xuan Ming Lun Fang* (Treatise on the Declaration of Clarity), prescriptions listed under various symptom categories address "Lou Feng" (Leaking Wind - a condition characterized by abnormal sweating due to wind invasion) accompanied by thirst, using *Muli* (Oyster Shell), *Fangfeng* (Saposhnikovia Root), and *Baizhu* (Atractylodes Macrocephala Rhizome), prioritizing the treatment of Lou Feng as an acute condition. If Heart transfers cold to the Lung, resulting in "Fei Xiao" (Lung Wasting-Thirst), the urgency lies in Heart-Fire overacting on the Lung and damaging Qi and Blood. The "transferred cold" here does not refer to a genuine pathogenic cold, but rather to deficiency; therefore, *Renshen* (Ginseng Radix et Rhizoma), [missing character, likely Huangqi], *Shudihuang* (Prepared Rehmannia Root), *Beiwuweizi* (Schisandra Chinensis Fruit), *Sangbaipi* (Morus Alba Bark), *Mendong* (Ophiopogon Tuber), and *Gouqi* (Lycium Barbarum Fruit) are used to first rescue the decline of Qi and Blood, hence cold-natured drugs for clearing internal heat are not employed. If Heart transfers heat to the Lung, transmitting it to become "Ge Xiao" (Diaphragm Wasting-Thirst), Lung heat becomes the urgent priority. *Mendong* (Ophiopogon Tuber) is used as the Sovereign herb to treat latent fire in the Lung; *Gualou* (Trichosanthes Fruit) and *Zhimu* (Anemarrhena Rhizome) act as Ministers to drain heat; *Gancao* (Licorice Root), *Beiwuweizi* (Schisandra Chinensis Fruit), *Shengdihuang* (Raw Rehmannia Root), *Gegen* (Pueraria Lobata Root), and *Renshen* (Ginseng Radix et Rhizoma) act as Assistants to generate fluids and benefit Qi and Blood. If Heart-Fire flares upward to invade the Lung, it must be because the Heart itself has pathology and was not properly regulated, leading to deficiency of Qi and Blood in the Zang organs, thereby causing Jueyin Liver Fire to rebel upward. Therefore, *Fushen* (Poria with Hostwood) is used to calm the mind, stabilize will, and nourish spirit, combined with the cooling properties of *Zhuye* (Bamboo Leaf) and *Mendong* (Ophiopogon Tuber) to settle the "dwelling" of the spirit, allowing the fire to find rest and subside. These three discussions on Wasting-Thirst reflect Liu Hejian’s (Liu Wan-su) approach to prescribing, weighing the appropriateness of addressing root and branch, urgency and slackness, severity and lightness, and selecting herbs that precisely target the affected Zang organs.

Depending on whether the Ministerial Fire (Ministerial Fire refers to the physiological fire that drives metabolic activities) is mild or excessive, mild cases are treated with orthodox methods (treating according to the nature of the disease), while excessive cases may require contrary methods (treating against the apparent symptoms). For symptoms such as phlegm agitation and bleeding, treatment is applied flexibly according to circumstances. Bleeding from Shaoshang (LU-11, located at the radial corner of the thumbnail) on the thumb can be used to move Qi. If swelling extends externally, external herbal applications are necessary. I once used a goose feather dipped in vinegar-water to stimulate the throat and extract phlegm. Sour flavors can astringe phlegm and resolve stagnant blood. If "Ru E" (Goat's Throat - tonsillar hypertrophy) is severe and does not dissipate, minor incisions can be made on the tonsils to release blood. *Mayaxiao* (Niter/Sodium Nitrate) is blown into the throat to reduce fire pathogens. Decoctions containing *Yeyan* (Belamcanda Rhizome), *Qingdai* (Indigo Naturalis), *Gancao* (Licorice Root), *Jiegeng* (Platycodon Root), *Zhizi* (Gardenia Fruit), *Huangqin* (Scutellaria Root), *Eshizi* (Arctium Fruit), and *Dahuang* (Rhubarb Root) are prescribed based on their beneficial effects to disperse Upper Jiao heat. External applications may include *Shengdihuang* (Raw Rehmannia Root), *Jiu Gen* (Chinese Chive Root), and *Fulonggan* (Stove Earth). If throat sores are white with much saliva, or red with much blood, they generally follow the same pattern as mouth ulcers. Decoctions of *Qiangwei Genpi* (Rose Root Bark), *Huangbai* (Phellodendron Bark), and *Qingdai* (Indigo Naturalis) can be held in the mouth and swallowed slowly. My teacher stated that Lizhong Tang (Regulate the Middle Decoction) can also be used for treatment; see details under the Mouth Ulcer section.
