（《唐本草》）
【释名】顽荆（《图经》）。
【集解】恭曰∶栾荆茎、叶都似石南，干亦反卷，经冬不死，叶上有细黑点者，真也
，今雍州所用者是。而洛州乃用石荆当之，非也。俗方大用，而本草不载，亦无别名。但有
栾华，功用又别，非此物花也。
颂曰∶栾荆今生东海及淄州、汾州。所生者皆枝茎白，叶小圆而青色，颇似榆叶而长
，冬夏不凋。六月开花，花有紫、白二种。子似大麻。四月采苗叶，八月采子。
宗 曰∶栾荆即牡荆也，子青色如茱萸，不合更立此条。苏恭又称石荆当之，转见穿凿
时珍曰∶按∶许慎《说文》云∶栾，似木兰。木兰叶似桂，与苏恭所说叶似石南者相近
。苏颂所图者即今牡荆，与《唐本草》者不合。栾荆是苏恭收入本草，不应自误。盖后人不
识
子
【气味】辛、苦，温，有小毒。
权曰∶甘、辛，微热，无毒。决明为之使。恶石膏。
【主治】大风，头面手足诸风，癫痫狂痉，湿痹寒冷疼痛（《唐本》）。四肢不遂，通血
脉，明目，益精光（甄权）。
合 油同熬，涂人畜疮疥
（《拾遗》）
【集解】藏器曰∶石荆似荆而小，生水旁，《广济方》一名水荆是也。苏颂言洛人以当
栾荆者，非也。
【主治】烧灰淋汁浴头，生发令长（藏器）。
(From *Tang Bencao*)
[Names] Wan Jing (Stubborn Vitex) (*Tujing*).
[Collection and Explanation] Su Gong stated: The stems and leaves of Luan Jing are similar to Shinan, and the branches also curl backwards. It does not die after enduring winter; those with fine black spots on the leaves are genuine. This is what is currently used in Yongzhou. However, Luozhou uses Shijing to substitute for it, which is incorrect. Although widely used in folk prescriptions, it is not recorded in the *Bencao* texts, nor does it have other aliases. There is a plant called Luan Hua, but its functions are different, and it is not the flower of this herb.
Su Song stated: Luan Jing is currently found in Donghai, as well as in Zizhou and Fenzhou. All specimens produced there have white stems and branches, small, round, green leaves that resemble elm leaves but are longer. They do not shed their leaves in winter or summer. They bloom in June, producing flowers of two colors: purple and white. The fruits resemble hemp seeds. The herbs and leaves are harvested in April, and the fruits in August.
Chen Cangqi stated: Luan Jing is actually Muzhing (Male Caste Tree). Its fruits are green like cornel berries. It should not have been listed as a separate entry. Su Gong's claim that Shijing is used to substitute for it further reveals forced interpretation.
Li Shizhen stated: According to Xu Shen's *Shuowen Jiezi*, "Luan resembles Mulan." The leaves of Mulan resemble those of Cassia, which is close to Su Gong's description of leaves resembling Shinan. The illustration provided by Su Song depicts current Muzhing, which does not match the records in *Tang Bencao*. Since Luan Jing was included in the *Bencao* by Su Gong, it should not be an error on his part. It is likely that later generations did not recognize its fruit...
[Properties and Flavor] Pungent, bitter, warm, slightly toxic.
Zhen Quan stated: Sweet, pungent, slightly hot, non-toxic. Jueming acts as its guide drug. It is incompatible with Gypsum Fibrosum.
[Indications] Treats Feng Da (Severe Wind disease), various wind-pathogen conditions affecting the head, face, hands, and feet; epilepsy, mania, and spasms; cold-damp bi syndrome causing pain (*Tang Bencao*). Relieves paralysis of the four limbs, unblocks blood vessels, brightens the eyes, and enhances visual clarity (Zhen Quan).
Boiled together with oil and applied topically to treat sores and scabies in humans and livestock.
(From *Xinxiu Bencao Shiyi*)
[Collection and Explanation] Chen Cangqi stated: Shijing resembles Jingthorn but is smaller, growing near water sources. It is also known as Shuijing (Water Jingthorn) in the *Guangji Fang*. Su Song's statement that people in Luozhou use it to substitute for Luan Jing is incorrect.
[Indications] Burned to ash, leached with water to obtain juice, and used to wash the hair to promote hair growth and length (Chen Cangqi).
