The head region belongs to the intersection of the Foot-Taiyang Bladder Meridian and the Du Vessel (as stated in *Ling Shu*: When the Foot-Taiyang meridian is affected, it causes sudden headache, eyes feeling as if they are protruding, and the neck feeling as if being pulled. As stated in *Su Wen*: In the first day of Cold Damage disease, the Ju Yang (Taiyang) receives the pathogen, hence headache. On the seventh day, when the Ju Yang disease declines, the headache subsides slightly. It also states: For heat diseases starting at the head and head, puncture the Taiyang area at the nape to induce sweating and stop the disease. It also states: In Jue syndrome of the Ju Yang, there is swelling and heaviness of the head, inability to walk, leading to falling). The head also belongs to the Foot-Yangming Stomach Meridian (*Ling Shu* states: The Luo-connecting vessel of the Foot-Yangming ascends along the lateral aspect of the tibia and connects with the head and nape. It also states: Stomach Qi flows upward into the Lung; its fierce Qi rushes upward to the head, traveling along the pharynx and ascending to the orifices. *Su Wen* states: When the guest Sun vessels of the Yangming are involved, headache, rhinorrhea, and abdominal swelling occur. Lou Quanshan said: When the pathology is in the Stomach causing headache, purgation must be used for recovery). The head also belongs to the Foot-Shaoyang Gallbladder Meridian (*Ling Shu* states: In Jue headache, severe headache occurs with surging pulses around the ears and heat; bloodletting should be performed, followed by treatment of the Foot-Shaoyang. Li Dongyuan said: Headache with tinnitus is due to Qi deficiency, treated primarily with Renshen (Ginseng Radix et Rhizoma) and Huangqi (Astragali Radix). Zhu Danxi said: Li Dongyuan's Qingkong Gao treats Shaoyang headache). Generally, the head belongs to the Three Yang meridians of the Hand and Foot and the Yangwei Vessel (*Ling Shu* states: The Three Yang meridians of the Hand travel from hand to head, while those of the Foot travel from head to foot. It also states: For half-head cold pain, first treat Hand-Shaoyang and Hand-Yangming, then Foot-Shaoyang and Foot-Yangming. *Su Wen* states: The five rows on the head, each with five points, are used to vent the rebellious heat of all Yang meridians. Wang Qixuan said: The meridians of the Three Yang all ascend to the head. The head is the convergence of the Three Yang. Zhang Zihe said: Persistent headache indicates pathology in the Three Yang meridians. Sun Jingsi said: Modern Toufeng (wind-disease of the head) is also caused by deficient Yang Qi. Shen Chengzhi said: The distribution of the head follows five rows. The central row starts from the anterior hairline, goes over the vertex down to the Dazhui point at the nape, belonging to the Du Vessel. One cun above the anterior hairline is named Shenting (DU24), an intersection of the Foot-Taiyang Bladder, Foot-Yangming Stomach, and Du Vessels. One cun above the posterior hairline is Fengfu (DU16); 0.5 cun below that is Yamen (DU15), both intersections of the Du and Yangwei Vessels. The second row is 1.5 cun lateral to the central row on either side, bounded anteriorly and posteriorly by the hairlines, belonging to the Foot-Taiyang Bladder Meridian. The third row is directly above the pupils on either side, also bounded by the hairlines, an intersection of the Foot-Taiyang Bladder, Foot-Shaoyang Gallbladder, and Yangwei Vessels). The head also belongs to the Foot-Jueyin Liver Meridian (*Ling Shu* states: In Jue headache, there is throbbing head pain, sadness, and tendency to weep; observe the pulsating vessels on the head and puncture severely painful areas until bleeding stops, then regulate the Foot-Jueyin. *Su Wen* states: In Liver Heat disease, rebellion causes dizziness and headache, with pulse qi rushing to the head. It also states: Visual blurring and swaying, vertigo, and deafness indicate excess below and deficiency above, with pathology in the Foot-Shaoyang and Foot-Jueyin. Note: Xunmeng refers to a sensation like something covering the head, swaying unsteadily; vertigo and deafness are signs of dizziness, constituting Liver Jue, suitable for Gouteng San. Wang Haicang said: Wine-soaked Danggui (Angelicae Sinensis Radix) treats various headaches. Since headaches mostly belong to Liver Wood, blood-invigorating/nourishing herbs are primary. Zhu Danxi said: Blood-deficiency headache attacking upwards from the temporal region (fish tail) involves connected head pain, treated primarily with Danggui and Chuanxiong, involving the Foot-Taiyang and Foot-Jueyin meridians). It is also associated with the Foot-Shaoyin Kidney Meridian (*Ling Shu* states: In Jue headache, heavy and painful head requires draining the five rows on the head, first treating Hand-Shaoyin, then Foot-Shaoyin. Xu Zhike said: Liver deficiency causes upper deficiency, leading to dizziness; Kidney deficiency causes lower deficiency, leading to headache. Li Dongyuan said: In cases of Jue headache caused by severe cold invading to the bone marrow, since marrow is dominated by the brain, brain rebellion causes brain pain and tooth pain, suitable for Qianghuo Fuzi Tang). The head is also separately attributed to the Six Foot Meridians (Li Dongyuan said: Treating headache requires Chuanxiong. If ineffective, add guiding herbs according to the meridian: Chuanxiong for Taiyang, Baizhi for Yangming, Chaihu for Shaoyang, Cangzhu for Taiyin, Xixin for Shaoyin, Wuzhuyu for Jueyin. He also stated: For Taiyang headache with floating-tight pulse, use Chuanxiong, Qianghuo, Mahuang. For Shaoyang headache with wiry-thin pulse and alternating chills and fever, use Chaihu, Huangqin. For Yangming headache with spontaneous sweating, fever without aversion to cold, and long-floating pulse, use Shengma, Gegen, Shigao, Baizhi. For Taiyin headache with phlegm, heavy body, and abdominal pain (phlegm-stagnation), use Cangzhu, Banxia. For Shaoyin headache with non-circulation of the Three Yin and Three Yang meridians, cold feet and rebellious Qi constituting Cold Jue, with deep-thin pulse, use Mahuang Fuzi Xixin Tang. For Jueyin headache with vomiting of frothy saliva, cold Jue, and deep-slow pulse, use Wuzhuyu Tang)).
