[Shilongchu]
Bitter, slightly cold (Note: The original text mentions "slightly warm," but based on the analysis by Tao Hongjing and the Tang Bencao commentary, which states it clears heat when taken, it is considered not warm), non-toxic. It primarily treats evil qi in the heart and abdomen, difficult urination, strangury and urinary retention, wind-dampness, ghostly fixation and toxic vapors, tonifies internal deficiency and insufficiency, fullness and distension, lack of luster in the body, sweating, eliminates burning pain in the urethra, and kills ghostly fixation and toxic vapors. Long-term use tonifies emaciation, lightens the body, improves hearing and vision, and prolongs life. Also known as Longxu, Cao Xuduan, Zhenzhu, Longhua, Xuanwan, and Caodu. Those with nine nodes and rich aroma are superior. It grows in the valleys and wetlands of Liangzhou. The stems are harvested in May and July and dried in the sun.

Tao Hongjing said: The stems are green, thin, and connected, with red fruits. It is now produced near roads in watery and rocky areas, resembling the Longxu grass from Dongyang used to make mats, but with more nodes. The *Tang Bencao* commentary notes: *Mingyi Bielu* says it is also called Fangbin. It mainly treats roundworms and indigestion. Upon examining other versions of the commentary: *Mingyi Bielu* states it is slightly warm, but current usage clears heat, implying it is not actually warm. Ministers Yu Xi et al., according to the *Shu Ben Tu Jing*, stated: The stems resemble [text unclear], growing in clusters, commonly known as Longxu Grass. People currently use it to make mats; it is available everywhere. The roots are harvested in August and September and dried in the sun. Chen Cangqi said: According to records, if mats made of Longxu grass become old and dirty, taking one square chi boiled in water and drinking the juice treats strangury and sudden urinary obstruction. It is now produced in Fenzhou and is found everywhere.

Bitter, neutral, slightly cold, non-toxic. It primarily treats wind-damp bi syndrome, joint pain (Li Jie Tong), convulsions with tongue protrusion, palpitations and erratic qi, thief-wind, rat-sores and carbuncles, acute masses, promotes water metabolism, and treats flaccidity and paralysis. Long-term use lightens the body and brightens the eyes. Also known as Mi Xian, Cheng Gao, Cheng Ji, Wu Xin, and Wu Dian. It grows in the rivers and marshes of Hanzhong, as well as in Yuanju and Handan. The stems and leaves are harvested in July and dried in the shade. (It works well when combined with Qin Pi.)

Tao Hongjing said: It is rarely used by common people. The *Tang Bencao* commentary notes: This herb grows in clusters, resembling *Leonurus japonicus* (Chongwei) and *Pedicularis resupinata* (Baitouweng), with hairy leaves and red stems. It is highly effective for treating thief-wind. People in the south call it Wufeng Grass, also known as Luxian Grass, saying that deer eat this grass to recover from illness. There are two varieties, large and small; people in Chu still refer to the large one as Da Wufeng Grass and the small one as Xiao Wufeng Grass. Examining Chen Cangqi's *Bencao*: Women who take it will suffer from infertility. Ministers Yu Xi et al., according to the *Shu Ben Tu Jing*, stated: The leaves resemble *Leonurus japonicus*, growing in clusters, hairy, with yellow flowers and dark red-black roots.

Chen Cangqi said: Also known as Wu Xin Grass, not meaning the grass has no heart. People in the south call it Wufeng Grass, but it is not used in prescriptions. The *Suwen* records: The Yellow Emperor asked: A patient has a hot body, physical weakness and collapse, profuse sweating like bathing, aversion to wind, and shortness of breath. What disease is this? Qibo replied: The disease is named Jiufeng (Wine Wind). The Emperor asked: How to treat it? Qibo replied: Use Ze Xie (Alisma Rhizome) and Bai Zhu (Atractylodis Macrocephalae Rhizoma) each in ten parts, and Mi Xian (Dendrobii Officinalis Caulis / or specific herb contextually identified as such in ancient texts, here transliterated as Mi Xian) in five parts. Mix them and take three finger-pinches after meals.
