(Compendium of Materia Medica)
[Names] Xiannü Jiao (Fairy's Delight)
[Collected Explanations] Li Shizhen stated: Jiuxianzi (Nine Immortals Root) originates from Mount Taihe in Junzhou. One root connects nine tubers; the larger ones are like chicken eggs, and the smaller ones are like Pinellia ternata (Banxia). They are white in color. In the second lunar month, shoots emerge, with vines growing six or seven chi high. The stems are slender and smooth. The leaves resemble those of Sapium sebiferum (Wu You), but are shorter, flatter, and not round. At the forks of each leaf, subsidiary branches arise, either one or two, hanging gracefully. In the sixth and seventh lunar months, small greenish-yellow flowers bloom, followed immediately by fruit formation. The seeds grow in clusters, resembling those of Cyperus esculentus (Gujingcao). The roots are harvested in the ninth lunar month.
[Flavor and Properties] Bitter, cool, non-toxic.
[Indications] Sore throat, Hou Bi (obstruction and swelling of the throat), disperses blood stasis. Grind with fresh well water or vinegar to extract juice, hold in the mouth and swallow; this is very effective (Li Shizhen).
(Song Dynasty Kai Bao Ben Cao)
[Names] Jiedu (Detoxifier) (Compendium of Materia Medica), Huangjie (Yellow Knot) (Compendium of Materia Medica)
Su Song stated: Its vines resemble those of soybeans, hence the name.
[Collected Explanations] Su Song stated: Shandougen (Sophorae Tonkinensis Radix et Rhizoma) grows in the valleys of Jiannan, as well as Yizhou and Guozhou. It is also found in Guangxi today, with those from Zhongzhou and Wanzhou being of superior quality. The seedlings and vines resemble legumes, with green leaves that do not wither in winter. The roots are harvested in the eighth lunar month. In Southern Guangnan, it resembles a small locust tree, growing over one chi high; the stone rat feeds on its roots. Therefore, people in Lingnan capture rats, dry their intestines and stomachs, and use them to detoxify and clear heat, which is highly effective.
[Flavor and Properties] Sweet, cold, non-toxic.
Li Shizhen stated: According to Shen Kuo's "Dream Pool Essays," Shandougen has an extremely bitter taste. The Materia Medica stating it is sweet is a significant error.
[Indications] Resolves toxicity of various medicines, relieves pain, reduces carbuncles and toxic swellings, treats fever and cough, cures acute jaundice in humans and horses, and kills small insects (Kai Bao Ben Cao).
Holding it in the mouth and swallowing the juice effectively resolves throat swelling and toxicity (Su Song).
It treats abdominal distension due to Qi stagnation and expels Ascaris lumbricoides (Cunbai zhu chong). Taken as pills, it stops dysentery. Taken as a ground juice, it stops sudden onset of heat-jue heart and abdominal pain, and pain from five types of hemorrhoids. Applied as juice, it treats various heat-induced swellings, alopecia barbae, and injuries from snakes, dogs, and spiders (Li Shizhen).
[Attached Prescriptions] Ten old prescriptions, three new ones.
