（《素问·病能论》）
帝曰∶有病怒狂者，此病安生？（怒狂者，多怒而狂也，即骂詈不避亲疏之谓。）岐伯曰∶生于阳也。帝曰∶阳何以
使人狂？岐伯曰∶阳气者因暴折而难决，故善怒也，病名曰阳厥。（阳气宜于畅达，若暴有折 ，则志无所伸，或事有难
决，则阳气被抑，逆而上行，故为怒狂，病名阳厥。）帝曰∶何以知之？岐伯曰∶阳明者常动，巨阳、少阳不动，不动而
动大疾，此其候也。（阳明常动者，谓如下关、地仓、大迎、人迎、气冲、冲阳之类，皆有脉常动者也。巨阳、少阳不动
者，谓巨阳惟委中、昆仑，少阳惟听会、悬钟，其脉虽微动，而动不甚也。于其不甚动者而动且大疾，则其常动者更甚
矣，此即阳厥怒狂之候。）帝曰∶治之奈何？岐伯曰∶夺其食即已。夫食入于阴，长气于阳，故夺其食即已。（五味入口
而化于脾，食入于阴也。藏于胃以养五脏气，长气于阳也。食少则气衰，故节夺其食，不使胃火复助阳邪，则阳厥怒狂
者可已。）使之服以生铁洛为饮，夫生铁洛者，下气疾也。（生铁洛，即炉冶间锤落之铁屑，用水研浸，可以为饮，其属
金，其气寒而重，最能坠热开结，平木火之邪，故可以下气疾、除狂怒也。凡药中用铁精、铁华粉、针砂、铁锈水之类，
皆同此意。癫狂详义，见针刺类三十七，当与此互阅。）
Yellow Emperor asked: There are cases of disease characterized by anger and mania. How does this disease arise? (Anger and mania refer to frequent anger and mental derangement, specifically cursing without distinction between relatives and strangers.) Qibo replied: It arises from Yang. The Yellow Emperor asked: How can Yang cause a person to become manic? Qibo said: When the Qi of Yang is suddenly frustrated and difficult to resolve, it leads to irritability; this disease is named Yang Jue (Yang reversal). (The Qi of Yang should be smooth and unobstructed. If suddenly frustrated, the will cannot be expressed; or if matters are difficult to decide, Yang Qi is suppressed and rebels upward, leading to anger and mania, hence the name Yang Jue.) The Yellow Emperor asked: How do we know this? Qibo said: The Maiyang channel (Stomach Meridian) usually has pulsation, whereas the Juyang (Taiyang) and Shaoyang channels do not. If the latter pulse rapidly where they normally do not, this is the sign. (By "Maiyang usually pulses," it refers to acupoints such as Xiaguan, Dicang, Daying, Renying, Qichong, and Chongyang, where arterial pulses are constantly felt. By "Juyang and Shaoyang do not pulse," it refers to Weizhong and Kunlun for Juyang, and Tinghui and Xuanzhong for Shaoyang; their pulses are slight and not prominent. If these areas show vigorous pulsation, the pulsation in the normally active Maiyang channel would be even more intense, which is the sign of Yang Jue with anger and mania.) The Yellow Emperor asked: How should it be treated? Qibo said: Depriving them of food will cure it. Food enters the Yin and augments Yang Qi; therefore, depriving them of food cures it. (The five flavors enter and are transformed by the Spleen, representing food entering Yin. Stored in the Stomach to nourish the Qi of the Zang-Fu organs, it augments Yang. Reducing food intake reduces Qi; thus, restricting food prevents Stomach Fire from assisting Yang pathogenic factors, allowing Yang Jue and mania to subside.) Administer a decoction made of Shengtie Luo (Iron Filings). Shengtie Luo has the effect of rapidly descending Qi. (Shengtie Luo refers to iron filings hammered off during smelting, which can be soaked in water and drunk. It belongs to Metal, is cold and heavy in nature, and is most effective at suppressing heat, opening stagnation, and pacifying Wood and Fire pathogenic factors. Thus, it descends rebellious Qi and eliminates mania. Medicines using Tie Jing, Tie Hua Fen, Zhen Sha, or Iron Rust Water share this intent. Detailed meanings of Dian Kuang are found in Section 37 of the Acupuncture category and should be cross-referenced here.)
