【释名】 子。
时珍曰∶生于附子之侧，故名。许慎《说文》作 子。
【集解】弘景曰∶此附子边角之大者，削取之。昔时不用，比来医家以疗香港脚多验。
恭曰∶侧子、附子，皆是乌头下旁出者。以小者为侧子，大者为附子。今以附子角为侧
子，理必不然。若当阳以下、江左、山南、嵩高、齐鲁间，附子时复有角如大豆许。夔州以
上剑南所出者，附子之角，但如黍粟，岂可充用？比来都下皆用细附子有效，未尝取角也。
保升曰∶今附子边，果有角如大枣核及槟榔以来者，形状自是一颗，且不小。乃乌头旁
出附子，附子旁出侧子，甚明。
时珍曰∶侧子乃附子旁粘连小者尔，故吴普、陶弘景皆指为附子角之大者。其又小于侧
子者，即漏篮子矣。故杨氏《附子记》言∶侧子、漏篮，园人皆不重之，以乞役夫。
【修治】同附子。
【气味】辛，大热，有大毒。
普曰∶神农、岐伯∶有大毒。八月采。畏恶与附子同。
【主治】痈肿，风痹历节，腰脚疼冷，寒热鼠 。又堕胎（《别录》）。
疗香港脚，冷风湿痹，大风筋骨挛急（甄权）。冷酒调服，治遍
【发明】机曰∶乌头乃原生之脑，得母之气，守而不移，居乎中者也。侧子散生旁侧，
体无定在，其气轻扬，宜其发散四肢，充达皮毛，为治风之药。天雄长而尖，其气亲上，宜
其补上焦之阳虚。木鳖子则余气所结，其形摧残，宜其不入汤服，令人丧目也。
时珍曰∶唐·元希声侍郎，治瘫痪风，有侧子汤，见《外台秘要》，药多不录。

【释名】 侧子。
李时珍说：生长在附子旁边，所以叫这个名字。许慎在《说文解字》中写作“侧子”。
【集解】陶弘景说：这是附子边角上较大的部分，削取下来使用。过去不使用，近来医家用来治疗脚气病多有效验。
苏恭说：侧子和附子，都是乌头旁边长出的附属物。小的称为侧子，大的称为附子。现在把附子的角状部分当作侧子，道理上一定不对。如果在阳城以下、江东、山南、嵩山、齐鲁之间，附子偶尔会有像大豆那样大小的角状突起。夔州以上剑南地区出产的，附子的角状突起只有黍米、粟米大小，怎么可以充作药用？近来京城都使用细小的附子有效，从未取用角状部分。
马志说：如今附子边缘，确实有像大枣核及槟榔大小的角状物，形状自然是一颗完整的，而且不小。这分明是乌头旁生出的附子，以及附子旁生出的侧子。
李时珍说：侧子不过是附子旁边粘连生长的小块罢了，所以吴普、陶弘景都指认为是附子角状部分中较大的那些。比侧子更小的，就是漏篮子了。所以杨氏《附子记》中说：侧子和漏篮，种植园的人都不重视，把它们送给劳役的仆役。
【修治】 处理方法同附子。
【气味】 辛味，大热，有大毒。
吴普说：神农、岐伯认为：有大毒。八月采集。畏恶性质与附子相同。
【主治】 痈肿，风痹历节痛，腰脚疼痛发冷，寒热往来及鼠瘘（淋巴结核）。又能堕胎（出自《名医别录》）。
治疗脚气病，冷风湿痹，大风引起的筋骨拘挛急迫（出自甄权）。用冷酒调服，可治疗遍身……（原文此处似有缺漏或断句问题，依文意译为：治疗遍身……）
【发明】 寇宗奭说：乌头是原生的主根头部，得母体之气，坚守不移，居于中央。侧子散生于旁侧，位置不固定，其气轻扬升散，适宜发散四肢，通达皮毛，是治疗风邪的药物。天雄长得细长且尖，其气趋向于上，适宜补益上焦的阳虚。木鳖子则是余气凝结而成，形体摧残破损，适宜不入汤剂服用，否则令人失明。
李时珍说：唐代元希声侍郎，治疗瘫痪风，有用侧子汤，见于《外台秘要》，药物组成大多未收录。
(Recorded in the Lower Category of *Bie Lu*)
[Names] Cezi.
Li Shizhen stated: It grows on the side of Fuzi (Processed Lateral Root of Aconitum carmichaelii), hence the name. Xu Shen's *Shuowen Jiezi* writes it as "Cizi".
[Collected Explanations] Tao Hongjing said: This is the larger part from the corners and edges of Fuzi, which is sliced off for use. It was not used in ancient times; recently, physicians have found it effective in treating Hongjiaojing (Gouty Arthritis/Chronic Foot Edema).
Su Gong said: Both Cezi and Fuzi are lateral outgrowths of Wutou (Radix Aconiti). The smaller ones are called Cezi, and the larger ones are called Fuzi. To regard the horn-like projections of Fuzi as Cezi is certainly incorrect. In regions south of Yangcheng, Jiangzuo, Shannan, Songgao, and Qilu, Fuzi occasionally has horn-like projections the size of soybeans. However, those produced in Jiannan north of Kuizhou have horn-like projections only the size of millet grains; how can these be used? Recently, fine Fuzi has been effective in the capital without taking the horn-like parts.
Bao Sheng said: Currently, there are indeed horn-like projections on the edges of Fuzi, some as large as jujube pits or betel nuts, forming a distinct, substantial entity. It is clear that these are Fuzi growing laterally from Wutou, and Cezi growing laterally from Fuzi.
Li Shizhen said: Cezi is merely the small pieces adhering to the side of Fuzi. Therefore, Wu Pu and Tao Hongjing both identified them as the larger horn-like parts of Fuzi. Those smaller than Cezi are called Loubanzi. Thus, Yang's *Fuzi Ji* states: Gardeners do not value Cezi and Loubanzi, often giving them to laborers.
[Preparation] Same as Fuzi.
[Properties and Flavors] Acrid, very hot, highly toxic.
Wu Pu said: Shennong and Qibo stated: Highly toxic. Harvested in August. Its incompatibilities and aversions are the same as Fuzi.
[Indications] Carbuncles and swellings, wind-bi with joint pain throughout the body, cold pain in the waist and feet, alternating chills and fever, and shulou (scrofula/lymphatic tuberculosis). It can also induce abortion (*Bie Lu*).
Treats Hongjiaojing (Gouty Arthritis), cold-damp bi syndrome, and tendon spasms caused by severe wind (Zhen Quan). Taken with cold wine, it treats generalized... [Text appears incomplete here].
[Elucidation] Kou Zongshi said: Wutou is the original central root head, possessing the mother's qi, remaining fixed in the center. Cezi grows scattered on the sides, its position being indefinite, and its qi is light and ascending, making it suitable for dispersing to the four limbs and penetrating the skin and hair, serving as an herb for treating wind pathogens. Tianxiong is long and pointed, its qi tends upward, making it suitable for tonifying yang deficiency in the upper jiao. Mugua Zi (Mumiguo) is formed from residual qi, its shape being damaged, so it should not be taken in decoctions, lest it cause blindness.
Li Shizhen said: Yuan Xisheng, Vice Minister of the Tang Dynasty, treated paralysis-wind using Cezi Tang, recorded in *Waitai Miyao*, though most ingredients were not listed.
