Headache due to Kidney Deficiency arises from insufficiency of Kidney Yin, causing deficient Yang to lose its anchor and ascend upward. This corresponds to the "headache and cranial disease" mentioned in *Su Wen*, characterized by deficiency below and excess above, with pathology involving the Foot-Shaoyin (Kidney) and Foot-Taiyang (Bladder) meridians. Xu Xueshi refers to this as "Ren Jue Headache" (Kidney-Jue Headache).
Yuzhen Wan: Treats headache that is unbearable due to insufficient Kidney Qi and rebellious Qi ascending, termed Ren Jue. The pulse is wiry upon light palpation and firm upon heavy pressure.
Ingredients: Liu Huang (Sulfur, 2 liang), Shi Gao (Gypsum Fibrosum, calcined until red and ground), Ban Xia (Pinelliae Rhizoma Preparatum), Xiao Shi (Natrii Sulfas, each 1 liang, ground).
Preparation and Administration: Grind all ingredients into a fine powder and mix uniformly. Use fresh ginger juice to form pills the size of paulownia seeds. Dry them in the shade. Take 20 pills per dose, administered with ginger decoction or rice water. Moxibustion on Guanyuan (CV4) for 100 moxa cones is also beneficial. For patients with deficiency-cold constitution, remove Shi Gao and add Zhong Ru Fen (Stalactitum Powder, 1 liang).
Heixi Dan (from *Ju Fang*): Treats chronic cold of the Spleen Yuan, excess above and deficiency below, phlegm-fluid retention in the chest, or phlegm attacking the head and eyes; also used for Ben Tun (running piglet syndrome) with Qi rebellion, distension of both hypochondria, five types of fluid-retention diseases, Hong Kong jiao (gout/foot disease) attacking upward, sudden apoplexy, phlegm flooding obstructing the diaphragm, and disorders of non-ascending and non-descending Yin and Yang Qi.
Ingredients: Chen Xiang (Aquilariae Lignum Resinatum), Fu Zi (Aconiti Lateralis Radix Preparata), Hu Lu Ba (Trigonellae Semen), Rou Gui (Cinnamomi Cortex, each half liang); Hui Xiang (Foeniculi Fructus), Po Gu Zhi (Psoraleae Fructus), Rou Dou Kou (Myristicae Semen), Jin Ling Zi (Meliae Fructus), Mu Xiang (Aucklandiae Radix, each 1 liang); Hei Xi (Plumbum), Liu Huang (Sulfur, combined to form lead-sulfur cinnabar, each 2 liang).
Preparation and Administration: Grind all ingredients into powder and mix. Use wine-boiled wheat paste as a binder to form pills the size of paulownia seeds. Dry in the shade and polish with a cloth bag. Take 40 pills per dose, administered on an empty stomach with ginger-salt water. Another version includes Yang Qi Shi (Opscopiae Concha, half liang) and Ba Ji Tian (Morindae Officinalis Radix, 1 liang).
Liver-Jue Headache results from Liver Fire rebelling and ascending to attack the brain. The pain is invariably located at the vertex (top of the head) because the Liver Meridian intersects with the Du Mai (Governing Vessel) at the vertex. Although the Taiyang Meridian also ascends to the forehead and intersects at the vertex, Taiyang headache is invariably accompanied by aversion to wind and cold, whereas Jueyin (Liver) headache is often accompanied by vertigo, or cold limbs and twitching/spasms.
Longhui Wan (Formula see under "Jue Er" - Deafness due to Jue): Add Gan Ju (Chrysanthemi Flos) and Ling Yang Jiao (Capricornis Cornu) for cases with excess Qi and hard stool; for deficiency cases, use Sheng Di Huang (Rehmanniae Radix), Ling Yang Jiao, Gan Ju, and Mai Dong (Ophiopogonis Tuber) to nourish and clear heat, thereby softening the Liver so that Jue resolves spontaneously.
Yiqing Wan: Consists solely of Huang Lian (Coptidis Rhizoma), soaked overnight in Wu Zhu Yu Tang (Evodia Decoction), then ground into powder and formed into pills using congee.
Xieqing Wan: Dang Gui (Angelicae Sinensis Radix, de-radicle and dried), Long Dan Cao (Gentianae Radix), Chuan Xiong (Ligustici Chuanxiong Rhizoma), Zhi Zi (Gardeniae Fructus), Chuan Da Huang (Rhei Radix et Rhizoma, stir-baked), Qiang Huo (Notopterygii Rhizoma et Radix), Fang Feng (Saposhnikoviae Radix, de-radicle, equal parts).
Preparation and Administration: Grind into powder. Form pills the size of chicken beans using refined honey. Take one pill per dose, dissolved in warm water with rock sugar and Zhu Ye (Bambusae Folium) decoction.
