(Severe Headache, Parotitis, Pain of the Supraorbital Ridge, and Pain of the Eye Socket)
The head is the convergence point of all Yang meridians. If the Six Excesses (Six Qi) invade from outside, and the essence and nutrients become blocked internally, stagnating in the orifices and preventing the clear Yang from ascending and circulating, pain arises. The Classics state: Wind pathogens following the Fengfu point upward cause Brain Wind. Exposure to wind immediately after washing hair causes First Wind. Severe cold invading inwardly to the bone marrow causes Brain Reversal Headache. These above belong to headaches caused by Wind-Cold. Deficiency below and excess above constitute Kidney Reversal Headache. Headache accompanied by tinnitus and dysfunction of the nine orifices originates from the Stomach and Intestines; if headache is severe with whole-brain pain and cyanosis of hands and feet extending to the joints, it is incurable. Yang Qi exhaustion constitutes upper deficiency headache. Listed item by item, there are syndromes due to Wind, Cold, Dampness, Phlegm, Fire, Stagnant Heat, Hidden Summerheat, Food Injury, Alcohol Injury, Anger Injury, as well as Qi Deficiency, Blood Deficiency, True Headache, Migraine, Internal Wind disturbing the vertex, Kidney Deficiency with Water Flooding, and Kidney Deficiency with Qi Reversal.

For fluid retention in the Liver Meridian causing severe pain preventing eye opening, worse at night than during the day, Daotan Tang (Expelling Phlegm Decoction) is used.
Li Dongyuan stated: Headaches are often treated with Wind-dispersing herbs because only Wind herbs can reach the high vertex; herbs with thin flavors are Yang within Yin, ascending from earth to heaven. Taiyang Headache, characterized by aversion to wind and cold and a floating-tight pulse, is primarily treated with Chuanxiong (Ligustici Chuanxiong Rhizoma), Qianghuo (Notopterygii Rhizoma et Radix), Duhuo (Angelicae Pubescentis Radix), and Mahuang (Ephedrae Herba). Shaoyang Headache, characterized by a string-taut-thin pulse and alternating chills and fever, is primarily treated with Chaihu (Bupleuri Radix) and Huangqin (Scutellariae Radix). Yangming Headache, characterized by spontaneous sweating, alternating chills and fever, and a floating-slow-long-excess pulse, is primarily treated with Shengma (Cimicifugae Rhizoma), Gegen (Puerariae Lobatae Radix), Baizhi (Angelicae Dahuricae Radix), and Shigao (Gypsum Fibrosum). Taiyin Headache must involve Phlegm, with heavy body and abdominal pain, and a sinking-slow pulse, primarily treated with Cangzhu (Atractylodis Rhizoma), Banxia (Pinelliae Rhizoma Preparatum), and Nanxing (Arisaematis Cum Bile). Shaoyin Headache, characterized by cold feet and rebellious Qi constituting Cold Reversal, with a sinking-thin pulse, is primarily treated with Ma Huang Fu Zi Xi Xin Tang (Ephedra, Aconite, and Asarum Decoction). Jueyin Headache involving the neck, or accompanied by salivation and cold limbs with a floating-slow pulse, is primarily treated with Wuzhuyu Tang (Evodiae Fructus Decoction). Although the Taiyin and Shaoyin meridians do not ascend to the head, Phlegm and rebellious Qi obstructing the diaphragm prevent Qi from flowing freely in the head, causing pain. This is the treatment for Headache of the Six Meridians.
