(Song Dynasty *Tujing Bencao*)
[Collected Explanations] Song said: Fo Jia Cao (Sedum lineare) grows in Yinzhou. It mostly attaches to stones facing the sun, resembling Ma Chi Xian (Portulaca oleracea) but finer and longer, with yellow flowers, does not bear fruit, and is available throughout the four seasons.
Shizhen said: In the second month, seedlings emerge in clumps, four or five cun high. The stems are brittle and leaves fine, soft and lustrous like Ma Chi Xian, pointed, long, and small. It blooms yellow flowers in summer and withers after frost. People often plant it on rocky mountains or tile walls, calling it Fo Zhi Jia (Buddha's Fingernails). *Jiu Huang Ben Cao* states that plants one or two chi high with very large leaves are Jing Tian (Sedum sarmentosum), not this one.

[Flavor and Properties] Sweet, cold, slightly toxic.
[Indications] Burns and scalds; grind and apply topically (Song).

(*Bencao Gangmu*)

[Collected Explanations] Shizhen said: Hu Er Cao (Saxifraga stolonifera) grows in shady and damp places; people also cultivate it on rocky mountains. The stem is five or six cun high, covered with fine hairs, bearing one leaf per stem, shaped like a lotus leaf cover. People call it Shi He Ye. The leaves are as large as a coin, resembling the young leaves of common mallow or the ears of a tiger. It bears small pale red flowers in summer.
[Flavor and Properties] Slightly bitter, acrid, cold, slightly toxic.
Dugu Tao said: Its juice can boil sand.

[Names] Tian Hu Sui (Hebenstretia chinensis) (*Bencao Gangmu*), Ye Yuan Sui (same), E Bu Shi Cao (Goat Does Not Eat Grass) (*Shixing Bencao*), Ji Chang Cao (Chicken Intestine Grass) (see names below).
[Collected Explanations] Shizhen said: Shi Hu Sui is a small herb growing in stone crevices and shady, damp places. It is two or three cun high, sprouts in winter, with fine stems and small leaves, resembling tender Hu Sui (Coriander). Its odor is pungent and irritating, inedible, even goats refuse to eat it. It bears tiny yellow flowers in summer and produces small seeds. It propagates easily, covering remote areas. Note: Sun Simiao's *Qianjin Fang* mentions a small herb growing near water channels in damp places, resembling Hu Sui, named Tian Hu Sui, also called Ji Chang Cao. This is this herb. It shares the name "Ji Chang" with Fan Lv's (Stellaria media) chicken intestine but is a different substance.
[Flavor and Properties] Acrid, cold, non-toxic.
Shizhen said: Acrid, warm. Its juice can neutralize Pi Shi (Arsenic trioxide) and Xiong Huang (Realgar).
[Indications] Unblocks nasal qi, benefits the nine orifices, expels wind-phlegm (Bing). Removes eye nebula; stuff into nose, nebula falls naturally (Zangqi). Treats hemorrhoids (Shen). Detoxifies, brightens eyes, dissipates redness and swelling cloudiness, deafness, headache, and cerebral soreness, treats phlegm-malaria, nasal obstruction, stuffing nose causes polyps to fall, also dissipates sores and swellings (Shizhen).
[Elucidation] Shizhen said: E Bu Shi Cao has a warm temperature that rises and an acrid flavor that disperses; it is Yang, capable of connecting to Heaven. The head and lungs both belong to Heaven, thus it can reach the brain to treat vertex pain and eye diseases, unblock nasal qi and eliminate polyps; internally reaches the Lung meridian to treat phlegm-malaria and dissipate sores and swellings. Its efficacy is indeed comprehensive. Note: Ni Weide's *Yuanji Qiwei Ji* states: Bi Yun San for treating eye nebula uses E Bu Shi Cao detoxifying as the Sovereign drug, Qing Dai (Indigo Naturalis) clearing heat as the Assistant, Chuan Xiong (Ligusticum chuanxiong) strongly acrid breaking stagnation and removing evil as the Envoy; these are ascending and penetrating drugs. Generally, it is like opening a pot lid; one must ensure pathogenic evils do not close in, allowing them an exit. However, its power is small yet sharp; frequent use accumulates its strength. All eye diseases can utilize it. Raw use is more miraculous. Wang Xi's *Jiyao* poem says: After red eyes, nebula suddenly appears, named Goat Does Not Eat Grass in herbs. Frequently changed when stuffed in nose, within three days vision returns to clear.
