Luan Jing (Vitex negundo var. heterophylla)

Pungent, bitter, warm, slightly toxic. Primarily treats Feng Da (leprosy), wind pathogens affecting the head, face, hands, and feet, epilepsy, mania, spasms, and cold pain caused by Bi syndrome (obstruction). Folk prescriptions:
Used in large quantities, but not recorded in Ben Cao (Materia Medica), nor does it have an alternative name. There is Luan Hua (flower of Vitex negundo), which has different functions; it is not this flower.
Tang Ben Zhu (Note from Tang Dynasty Materia Medica) states: Observing its stems and leaves, they resemble Shi Nan (Acanthopanax sessiliflorus); the trunk also curls backward. It survives winter, and those with fine black spots on the leaves are authentic. The variety used in Yongzhou currently is this type. However, Luozhou uses Shi Jing to substitute for it, which is incorrect. (Originally attached in Tang Ben). Minister Yuxi et al. carefully note according to Yao Xing Lun (Discussion on Drug Properties): Luan Jing Zi (seed of Vitex negundo var. heterophylla) is the Jun (Emperor/Monarch) herb, adverse to Shi Gao (Gypsum Fibrosum), sweet and pungent, slightly warm, non-toxic. It can treat inability to move the four limbs, primarily unblocking blood vessels, brightening the eyes, and benefiting essence and luster. Jue Ming (Cassiae Semen) serves as the Shi (Assistant/Envoy) herb.
Tu Jing (Illustrated Canon) states: Luan Jing, old texts do not specify the provinces where it originates; now it grows in Donghai, Zizhou, and Fenzhou. Nature is warm, taste is bitter, slightly toxic. Seedlings and leaves primarily treat severe mania, spasms, Bi syndrome, and cold diseases. Su Gong says: Stems and leaves resemble Shi Nan; the trunk naturally curls backward, does not wither in winter, and those with fine black spots on the leaves are authentic. What is presented by various commanderies now has white stems, small, round, green leaves, somewhat resembling elm leaves but longer, remaining evergreen in winter and summer. Seeds are harvested in the sixth and seventh months. Boiled together with Di Li Qing (Bitumen), it is applied to sores and scabies on camels and livestock, or used in Lin Yao Zha (medicated washes for urinary issues); it is also called Wan Jing (Stubborn荆).
Yan Yi (Supplementary Meaning) states: Luan Jing is the Mu Jing (Vitex negundo) mentioned earlier; it should not be listed as a separate entry. Moreover, Ben Jing (Shennong's Classic of Materia Medica) originally did not include Luan Jing, which was already covered in the entry for Man Jing Shi (Viticis Fructus).

Fu Mu Pi (Bark of Fu Tree)

Bitter, neutral, slightly toxic. Expels wind and blood stasis, treats Hong Jiao (Beriberi/Foot Qi) pain and obstruction, breaks up bruised blood, and relieves unbearable pain. Take the white bark, roast it over fire, soak it in wine, and ingest. Boil it with Wu Mu Pi (barks of five trees) to make a decoction, and rub it on swollen and painful Hong Jiao areas. It kills Zhu Chong (chillworms causing chilblains) and Feng Sao (wind-induced itching). Burn it into ash, place it in wine, let the flavor become pure, and it will not spoil after a long time. Grows in mountain valleys in Jiangnan. The tree is several zhang in circumference. Leaves move without wind; flowers reverse before closing. The Book of Songs says: "The flowers of Tang Di turn back." Zheng Xuan's commentary states: "Tang Di is Yu Li (Prunus japonica), also called Yang." Cui Bao says: "Yang has round leaves and weak pedicels, swaying greatly in even a slight breeze." (Newly supplemented, see Chen Cangqi.)
