一谷周麻。生益州山谷。二月、八月采根，晒干。
旧出宁州者第一，形细而黑，极坚实，顷无复有。今惟出益州，好者细削，皮青绿色，
谓之鸡骨升麻。北部间亦有，
形又虚大，黄色。建平间亦有，形大味薄，不堪用。人言是落新妇根，不必尔。其形自相似，
气色非也。落新妇亦解毒，
取叶 作小儿汤浴，主惊忤。
为君，味苦，平、微寒，无毒。主心腹，去肠胃中结气，饮食积聚，寒热邪气，推陈致
新。除伤寒心下烦热，诸痰
热结实，胸中邪逆，五脏间游气，大肠停积水胀，及湿痹拘挛，亦可作浴汤。久服轻身，明

〔谨案〕茈是古柴字。《上林赋》云∶茈姜。及《尔雅》云∶
藐，茈草，并作茈字。且此草，根紫色，今太常用茈胡是也。又以木代系，相承呼为茈胡。
且检诸本草，无名此者。伤寒大小柴胡汤，最为痰气之要，若以芸蒿根为之，更作茨音，大
谬矣。
味甘、苦，性平、微寒，无毒。主治解除各种毒素，杀灭百精老物殃鬼，辟除温疫、瘴气、邪气、蛊毒。

一谷周麻。生长在益州的山谷中。二月、八月采集根部，晒干。
以前出产于宁州的最好，形状细长而黑，极其坚实，近来已不再出产。现在只出产于益州，好的细削，皮呈青绿色，称为鸡骨升麻。北部地区也有，形状虚大，黄色。建平地区也有，形状大味道淡薄，不堪使用。人们说是落新妇的根，不一定如此。它们的形状自然相似，但气味颜色不同。落新妇也能解毒，取叶子煮水给小儿洗澡，主治惊忤（小儿受惊吓或突发惊厥）。
作为君药（方剂中起主要治疗作用的药物），味苦，性平、微寒，无毒。主治心腹疾病，去除肠胃中的结气，饮食积聚，寒热邪气，推陈出新。清除伤寒引起的心下烦热，各种痰热结实，胸中邪逆，五脏间的游气，大肠停积水胀，以及湿痹拘挛，也可以用作洗浴汤剂。长期服用身体轻盈，明目，益精。又名地薰，又名山菜，又名茹草，叶名芸蒿，辛香可食用。生长在洪农川谷及宛朐，二月、八月采集根部，曝晒干燥。
与茯苓、桔梗、大黄、石膏、麻子仁、甘草、桂配伍，用水一斗煮取四升，加入硝石三方寸匕，治疗烦满。半夏为其使药（辅助主药增强疗效的药物），厌恶皂荚，畏惧女菀、藜芦。现在出产于近道，形状像前胡。
蒿叶似邪蒿，春秋季节有白色花，长四、五寸，香美可食用，长安及河内都有。此柴胡是治疗伤寒的第一要药。
〔谨案〕茈是古柴字。《上林赋》说：茈姜。以及《尔雅》说：藐，茈草，都写作茈字。而且这种草，根紫色，现在太常用茈胡就是它了。又以木代系，相承呼为茈胡。并且检查各种本草，没有名为此者。伤寒大小柴胡汤，最为痰气之要，如果用芸蒿根代替，更是大错特错。

Yigu Zhouma. Grows in the valleys of Yizhou. Roots are harvested in February and August and dried in the sun.
Those formerly produced in Ningzhou were the best, slender and black, extremely solid, but no longer available. Now only produced in Yizhou; the good ones are slender and peeled, with greenish-blue skin, called Jigu Shengma (Cimicifugae Rhizoma). Northern regions also have them, which are hollow and large, yellow. Jianping region also has them, which are large and tasteless, unfit for use. People say they are roots of Astilbe chinensis (Luoxinfu), not necessarily so. Their shapes naturally resemble each other, but their qi and color differ. Luoxinfu can also resolve toxins; its leaves boiled as a bath for children treat infantile convulsions (infantile fright/convulsion).
As the sovereign drug (the principal herb in a prescription), bitter in flavor, neutral and slightly cold in nature, non-toxic. Primarily treats heart and abdominal disorders, removes stagnant qi in the stomach and intestines, food accumulation, cold and heat evil qi, pushes out the old and generates the new. Clears heart vexation and heat caused by Shanghan (Cold Damage disease), various phlegm-heat solidifications, rebellious evil qi in the chest, wandering qi among the five zang organs, water retention and distension in the large intestine, and damp-bi with spasms. It can also be used as a bathing decoction. Long-term use lightens the body, brightens the eyes, and benefits essence. Also known as Dixun, Shancai, Rucao; the leaf is called Yunhao, pungent and fragrant, edible. Grows in Hongnong river valleys and Wanqu. Roots are harvested in February and August and dried in the sun.
When combined with Poria cocos (Fuling), Platycodon grandiflorus (Jiegeng), Rheum palmatum (Dahuang), Gypsum fibrosum (Shigao), Cannabis sativa seed (Maziren), Glycyrrhiza uralensis (Gancao), and Cinnamomum cassia (Gui), boiled in ten dou of water to yield four sheng, with added Natrii Sulfas (Xiaoshi) three square-inch spoons, it treats vexation and fullness. Banxia is its minister drug, dislikes Gleditsia sinensis (Zaojiao), fears Aster tataricus (Nüwan) and Veratrum nigrum (Lilu). Currently produced in nearby regions, resembling Peucedanum praeruptorum (Qianhu).
The leaf resembles Artemisia capillaris (Xiehao); in spring and autumn, white flowers appear, four to five cun long, fragrant, sweet, and edible. Available in Chang'an and Henei. This Chaihu is the primary herb for treating Shanghan.
[Respectful Note] Zi is the ancient character for Chai. The "Shanglin Fu" states: Zi Jiang. And the "Erya" states: Miao, Zi Cao, both written as Zi. Moreover, this herb has purple roots; currently, Zihu is commonly used. It was later written with the wood radical instead of the silk radical, inherited as Zihu. Furthermore, checking various Bencao texts, none name it thus. Shanghan Xiaochaihu Tang and Dachaihu Tang are crucial formulas for phlegm-qi disorders; if Yunhao root were used instead, it would be a grave error.
