【释名】凌泉（出自《神农本草经》）、大就（出自《神农本草经》）。
李时珍说：这种植物叶子呈黄色且圆形，所以名叫黄环，有如同萝白环的含义。它也是葛类植物，所以名叫就葛。“跋”是野兽脚的名称，它的豆荚形状像兽足，所以叫作野狼跋子。
【集解】《名医别录》说：黄环生长在蜀郡的山谷中。三月采集根部，阴干备用。
吴普说：蜀地的黄环，又名生刍。二月长出苗茎，颜色正红，高度约二尺。叶子黄色、圆形、顶端较大，经过日晒后叶面会有黄白色的汁液。五月果实圆润。三月采集根部，根部呈黄色，纹理顺直，像车轮的辐条一样散开。
陶弘景说：外形类似防己（Pseudostellaria heterophylla），也呈现车轮辐条状的纹理。《蜀都赋》中说：“青珠黄环”，指的就是这种药。有人说它是大戟花，这肯定不对。它使用很少，市场上很少有人认识它。又说：野狼跋子产于交州和广州地区，形状扁平。将其捣碎混合米投入水中，无论鱼的大小都会浮出水面而死。
苏恭说：黄环只有襄阳地区大量出产，其他地方虽有但也稀少，巴西人称之为就葛，现在庭院中也种植它。它是藤本植物生长，粗大的茎直径可达六、七寸，根部也是葛类，陶弘景说它像防己，比较接近。如果误食葛根，会导致呕吐腹泻不止，用土浆可以解毒，这才是真正的黄环。现在太常寺收集的来自剑南地区的药材，其实是鸡屎葛根，并非黄环。它的花是紫色的，它的果实名叫野狼跋子，角状生长，类似皂荚。从交广地区送入太常寺的，正是黄环的种子。花和果实的成熟时间与葛相同。
李时珍说：吴普描述得非常详细，为什么唐宋时期的本草著作没有收录呢？《范子计然》说：黄环产自魏郡，以黄色者为上品。
【气味】味苦，性平，有毒。
吴普说：神农、黄帝认为有毒；桐君、扁鹊认为味苦。
雷敩说：大寒，有小毒。
徐之才说：鸢尾（Iris tectorum）是其引经药。畏茯苓（Poria）、防己（Stephaniae Tetrandrae Radix）、干姜（Zingiberis Rhizoma Preparata）。
【主治】蛊毒、鬼疰、鬼魅等邪气滞留脏腑之中，治疗咳嗽气逆、寒热往来（李时珍补充）。
治疗痰嗽，消除水肿，通利小便（李时珍补充）。
【附方】新方一则。

(Recorded in the Lower Category of *Shennong Bencao Jing* [Classic of Materia Medica])
Yelangbazizi (Recorded in the Lower Category of *Mingyi Bielu* [Additional Records of Famous Physicians])
[Names] Lingquan (from *Shennong Bencao Jing*), Da Jiu (from *Shennong Bencao Jing*).
Li Shizhen stated: This plant has yellow and round leaves, hence its name Huanghuan (Yellow Ring), implying a meaning similar to "white ring like a creeper." It belongs to the genus *Pueraria* (Kudzu), hence the name Jiuge. "Ba" refers to the foot of a wild beast; its pods resemble such feet, thus it is called Yelangbazizi (Wild Wolf's Paw).
[Collection and Explanation] *Mingyi Bielu* states: Huanghuan grows in the valleys of Shujun. The roots are harvested in March and dried in the shade.
Wu Pu stated: The Huanghuan from Shu is also known as Shengchu. Seedlings emerge in February, appearing bright red, reaching a height of two chi. The leaves are yellow, round, with broad tips; after sun exposure, yellowish-white juice appears on the leaf surface. The fruits become round in May. Roots are harvested in March; they are yellow with longitudinal fibers, resembling the spokes of a wheel.
Tao Hongjing stated: It resembles Fangji (*Stephaniae Tetrandrae Radix*), also showing a texture like wheel spokes. The *Shudu Fu* says: "Green pearls and yellow rings," referring to this herb. Some claim it is the flower of *Euphorbia*, which is definitely incorrect. It is rarely used, and few people in the market recognize it. He further stated: Yelangbazizi originates from Jiaozhou and Guangzhou, with a flat shape. When crushed and mixed with rice into water, fish of all sizes float up and die.
Su Gong stated: Huanghuan is abundant only in Xiangyang; although present elsewhere, it is rare. People in Baxi call it Jiuge, and it is now cultivated in gardens. It grows as a vine; thick stems have a diameter of six or seven cun. The root is also of the *Pueraria* type. Tao Hongjing's description that it resembles Fangji is close. If mistaken for Kudzu root (*Puerariae Lobatae Radix*) and ingested, it causes incessant vomiting and diarrhea, which can be resolved by drinking clay slurry. This is the true Huanghuan. The specimens collected by the Taichang Temple from Jiannan are actually Jishige roots (*Pueraria thomsonii*), not Huanghuan. Its flowers are purple; its fruit is named Yelangbazizi, growing in pods similar to Gengjiao (Soap Pod). Those sent to the Taichang Temple from Jiaozhou and Guangzhou are indeed the seeds of Huanghuan. The flowering and fruiting times coincide with those of Kudzu.
Li Shizhen stated: Wu Pu's description is very detailed, yet why was it omitted in the materia medica of the Tang and Song dynasties? *Fanzi Jiran* states: Huanghuan comes from Weijun, and those with yellow color are considered superior.
[Properties and Flavor] Bitter, neutral, toxic.
Wu Pu stated: Shennong and the Yellow Emperor considered it toxic; Tongjun and Bian Que considered it bitter.
Lei Xiao stated: Greatly cold, slightly toxic.
Xu Zhicai stated: Yuanwei (*Iridis Tectoris Rhizoma*) acts as its guiding drug. It is incompatible with Fuling (*Poria*), Fangji (*Stephaniae Tetrandrae Radix*), and Ganjiang (*Zingiberis Rhizoma Preparata*).
[Indications] Gu poison, Gui Zhu (ghostly infection), and Gui Mei (demonic influences); evil qi lodged within the Zang organs. Treats cough with inverted Qi, alternating chills and fever (supplemented by Li Shizhen).
Treats phlegm-cough, reduces edema, and promotes urination (supplemented by Li Shizhen).
[Attached Prescriptions] One new prescription.
Yelangbazizi
[Properties and Flavor] Bitter, cold, slightly toxic.
[Indications] Malignant sores, scabies. Kills parasites and fish (*Mingyi Bielu*). Applied topically with vinegar for sores and scabies is effective (Tao Hongjing).
