味苦，平，无毒。主蛇虺、蜂虿、 狗、菜肉、蛊毒，鬼疰，风疰，诸大毒不可入
口者，皆消除之。又去血，可末着痛上，立消。毒入腹者，煮饮之即解。一名白葛。生交州
山谷。
陶隐居云∶此药疗毒，莫之与敌，而人不复用，殊不可解，都不闻有识之者，想当似葛
尔，
须别广访，交州人未得委悉。唐本注云∶此草荆、襄间山谷大有，苗似萝摩，叶圆浓，茎俱
有白毛，与众草异。蔓生，山南俗谓之白葛。用疗毒有效。而交、广又有白花藤，生叶似女
贞，茎叶俱无毛，花白，根似野葛，云大疗毒，而交州用根不用苗，则非藿也。用叶苗者，
真矣。二物疗治，并如《经》说，各自一物，下条载白花藤也。臣禹锡等谨按蜀本图经云
∶蔓生，叶圆若 ，今襄州北、汝州南岗上有。五月、六月采苗，日干。
海药云∶主风邪热极，宜煮白兔藿饮之。干则捣末，敷诸毒妙。

味辛，温，无毒。主鬼物百精，蛊毒疫疾，邪恶气，温疟。久服强悍轻身，益气
延年。一名鬼督邮。生泰山山谷及陇西。三月采。
陶隐居云∶鬼督邮之名甚多。今俗用徐长卿者，其根正如细辛，小短扁扁尔，气亦相似。
今
狗脊散用鬼督邮，当取其强悍宜腰脚，所以知是徐长卿，而非鬼箭、赤箭。唐本注云∶此药
叶似柳，两叶相当，有光润，所在川泽有之。根如细辛，微粗长，而有臊（昔刀切）气。今
俗
用代鬼督邮，非也。鬼督邮别有本条在下。臣禹锡等谨按蜀本图经云∶苗似小麦，两叶相

[White Rabbit Huo]
Taste: bitter; Nature: neutral; Toxicity: non-toxic. It is indicated for snake bites, bee stings, dog bites, and poisoning from ingesting vegetables or meat, gu poison (poisoning caused by magical toxins), gui zhu (a contagious chronic wasting disease attributed to evil spirits), feng zhu (zhu disease caused by wind pathogen). It eliminates all kinds of severe toxins that cannot be taken orally. Furthermore, it removes blood stasis; when ground into powder and applied topically to painful areas, relief is immediate. If the toxin has entered the abdomen, decocting and drinking it resolves the toxicity. Also known as Bai Ge (White Kudzuvine). Grows in the valleys of Jiaozhou.
Tao Hongjing stated: "This herb is unmatched in treating toxins, yet people no longer use it, which is incomprehensible. No one seems to recognize it. I suspect it resembles Kudzuvine (Ge Gen), but further extensive investigation is required. The people of Jiaozhou are not fully acquainted with it."
The *Tang Bencao* annotation notes: "This herb is abundant in the valleys between Jingzhou and Xiangyang. Its seedlings resemble Metaplexis japonica (Luo Mo), with round, thick leaves and stems covered in white hairs, distinct from other weeds. It grows as a vine and is commonly called 'Bai Ge' in southern mountains. It is effective in treating toxins. However, in Jiaozhou and Guangzhou, there is another herb called Bai Hua Teng (White Flower Vine). Its leaves resemble Ligustrum lucidum (Nv Zhen), its stems and leaves are hairless, its flowers are white, and its root resembles wild Kudzuvine. It is said to be highly effective against toxins, but the people of Jiaozhou use only the root, not the seedlings; thus, it is not Huo. Those using the leaves and seedlings possess the true White Rabbit Huo. Both herbs have therapeutic effects as described in the *Shennong Bencao Jing*; they are two distinct substances. Bai Hua Teng is recorded in the following entry."
Ministers Yu Xi et al., according to the *Shu Ben Tu Jing*, state: "It grows as a vine with round leaves... It is found on hills north of Xiangzhou and south of Ruzhou. Collect the seedlings in May and June, and dry them in the sun."
*Hai Yao Ben Cao* states: "It treats extreme heat caused by wind pathogens; it is suitable to decoct White Rabbit Huo and drink it. When dried and ground into powder, it is excellent for applying to various toxins."
[Xu Chang Qing]
Taste: pungent; Nature: warm; Toxicity: non-toxic. It is indicated for ailments caused by evil spirits and myriad essences (gui wu bai jing), gu poison, epidemic diseases, evil qi, and wen nue (warm malaria). Long-term consumption makes the body strong, agile, and light, benefiting qi and prolonging life. Also known as Gui Du You. Grows in the valleys of Mount Tai and Longxi. Collected in March.
Tao Hongjing stated: "There are many names for Gui Du You. What is currently used as Xu Chang Qing has roots resembling Asarum (Xi Xin), though slightly shorter and flattened, with a similar aroma. In the preparation of Gou Ji San, Gui Du You is used for its ability to strengthen the waist and legs; therefore, we know this is Xu Chang Qing, not Gui Jian Yu (Arrowroot) or Chi Jian (Red Arrow)."
The *Tang Bencao* annotation notes: "The leaves of this herb resemble willow leaves, growing in opposite pairs with a glossy surface. It is found in marshes and rivers everywhere. The roots resemble Asarum but are slightly thicker and longer, possessing a fishy/musky odor (xi dao qie). Using it as a substitute for Gui Du You in current practice is incorrect. Gui Du You has its own separate entry below."
Ministers Yu Xi et al., according to the *Shu Ben Tu Jing*, state: "The seedlings resemble wheat, with opposite leaves. They are green in March, bear fruit in July and August (smaller than Metaplexis japonica fruits), turn yellow in September, and wither in October. It grows in low, wet marshes and is found in various places now. Collect in August and dry in the sun."
*TU Jing Ben Cao* states: "Xu Chang Qing grows in the rocky valleys of Mount Tai and Longxi. It is also found in the regions of Zizhou, Qizhou, Huai River, and Si River. Green seedlings emerge in March, with leaves resembling small mulberry leaves, growing in opposite pairs with a glossy surface. It bears fruit in July and August, resembling Metaplexis japonica but smaller. The seedlings turn yellow in September and wither in October. The roots are yellow, resembling Asarum but slightly thicker and longer, with a musky odor. Collect in March and April. Also known as Bie Xian Zong."
Lei Gong stated: "Upon collection, coarsely pound the herb, mix thoroughly with a small amount of honey, place in a porcelain vessel, steam during the three fu days (the hottest period of summer), and then dry in the sun for use."
