（本经上品）
扶疏处正显整密。整密处正见扶疏。
【气味】甘，微温，无毒。
【主治】主痈疽久败疮，排脓，止痛，大风癞疾，五痔，鼠 ，补虚，小儿百病。
【核】曰∶出蜀郡汉中，今不复采。唯白水、原州、华原山谷者最胜，宜、宁二州者亦
佳。春生苗，独茎丛生，去地二三寸。作叶扶疏，状似羊齿，七月开黄紫色花，结小尖角，
长寸许。八月采根，长二三尺，紧实若箭干，皮色黄褐，折之柔韧如绵，肉理中黄外白，嚼
之甘美可口。若坚脆味苦者，即苜蓿根也。勿误用木耆草，形类真相似，只是生时叶短根横
耳。修治去头上皱皮，蒸半日，劈作细条，槐砧锉用。茯苓为之使，恶龟甲、
先人云∶黄 一名戴糁，戴椹，百本。戴在首，如卫气出目行头，自上而下，从外而内，
百
矣。
【 】曰∶黄中色，通志云∶始生为黄， ，耆宿也。指使不从力役，如人胃居中，营
卫气血，筋脉齿发之属，莫不始生于胃，而卫气之 吸，营血之濡运，筋脉之展摇，齿发之
生长，亦莫不从胃指挥宣布。所谓外者中之使也，营血筋脉悉属有形，统御节制，唯一卫气，
所谓卫者气之帅也。痈疽久败、大风癞疾、五痔鼠 ，咸无卫气卫外，故肌肉腐烂。黄 味
甘气温，肉似肌腠，皮折如绵，宛若卫气之卫外而固者也。故能温分肉，充皮肤，肥腠理，
司开阖。唯卫气虚弱，不能固护肌肉者宜之。倘涉六淫，毒热炽盛，又当谢之，未可谬用。
补虚者，补卫气之虚，小儿阴常有余，气常不足，故百病咸宜也。
（涉六淫毒炽盛，亦非禁止不行，惟在颐指气使者何如耳。耆宿，则更事久历，事能尽
知，乃可颐指气使，不从力役。设非主张于内者，安能固护于外耶。）
[Shangpin (Superior Grade) of the Benjing]
Where branches and leaves are spread out, it precisely reveals their neatness and density; where they are neat and dense, it precisely shows their spreading distribution.
[Taste and Nature] Sweet, slightly warm, non-toxic.
[Indications] Primarily treats carbuncles, sores, and long-standing ulcerated wounds; expels pus, alleviates pain, treats severe wind-induced leprosy-like diseases (leprosy), five types of hemorrhoids (wuzhi), scrofula (shulou), tonifies deficiency, and treats various ailments in children.
[Verification] Says: Originates from Shujun and Hanzhong regions, but is no longer collected today. Those produced in Baishui, Yuanzhou, and Huayuan valleys are considered the best; those from Yizhou and Ningzhou are also excellent. Seedlings emerge in spring, growing singly in clusters, about two to three cun above the ground. Leaves are spread out, resembling ferns. Yellow-purple flowers bloom in the seventh lunar month, bearing small, pointed pods about one cun long. Roots are harvested in the eighth lunar month, measuring two to three chi in length, tight and solid like arrow shafts. The skin is yellow-brown; when broken, it is flexible and tough like cotton. The flesh is yellow inside and white outside, tasting sweet and pleasant when chewed. If hard, brittle, and bitter, it is the root of Medicago sativa (alfalfa). Do not mistakenly use Astragalus propinquus (muqi cao); although similar in appearance, its leaves are shorter and roots grow horizontally when fresh. For processing, remove the wrinkled skin at the top, steam for half a day (banri), split into thin strips, and chop on a locust wood (huai zhen) anvil. Poria cocos (Fuling) serves as its guiding herb; it is incompatible with Testudinis Carapax et Plastrum (Guijia).
Predecessors stated: Huangqi is also known as Daican, Daishen, and Baiben. "Dai" means wearing on the head, analogous to Wei Qi (Defensive Qi) originating from the eyes and circulating through the head, moving from top to bottom and from exterior to interior, covering all hundred bones.
[Collected Explanations] Says: "Huang" refers to yellow, which is the color of centrality. Tongzhi records: Initially born as "Huang," maturing into "Qi," meaning "Elder" or "Veteran." It implies commanding without engaging in manual labor, just as the Stomach resides centrally in the body, managing Ying Qi (Nutritive Qi), Wei Qi (Defensive Qi), blood, sinews, vessels, teeth, and hair. All these tangible structures originate from the Stomach. The inhalation of Wei Qi, the nourishment and circulation of Ying Blood, the extension and movement of sinews and vessels, and the growth of teeth and hair all follow the commands and directives of the Stomach. What is external is the envoy of what is internal. Ying Blood and sinews/vessels belong to tangible forms; their command and control rely solely on Wei Qi. Thus, it is said that "Wei Qi is the commander of Qi." Carbuncles, chronic ulcers, severe wind-leprosy, five hemorrhoids, and scrofula occur because there is a lack of Wei Qi protecting the exterior, leading to muscle decay. Huangqi has a sweet taste and warm nature; its texture resembles muscle and interstices, and its flexibility upon breaking is like cotton, resembling how Wei Qi protects the exterior and consolidates it. Therefore, it can warm the muscles, fill the skin, fatten the interstices, and regulate the opening and closing of pores. It is suitable only when Wei Qi is deficient and unable to consolidate the muscles. If affected by the Six Evils (Liu Yin) with intense toxic heat, it should be rejected and not used erroneously. "Tonifying deficiency" here refers to tonifying the deficiency of Wei Qi. Children often have excess Yin but insufficient Qi; thus, Huangqi is suitable for various childhood ailments.
(If affected by the Six Evils with intense toxic heat, it is not absolutely prohibited, but depends entirely on how the physician directs and utilizes it. An "Elder/Veteran" implies extensive experience and knowledge, capable of directing operations without manual labor. Without internal foundation and authority, how can there be external consolidation?)
