四方如意草
一名箭头草，剪刀草，大风草。百草镜云∶生山间或田塍，有紫白二种，紫花者名金剪
刀，
白花者名银剪刀，入药白花者良。叶与人家盆栽者无异，但花小，叶狭长而尖，微有别耳。
敏按∶山野间如意草，叶上尖下圆，深青色，与人家所种无异，惟叶色稍深绿耳。其花
亦
与如意草一类二种，其性情功效，亦不甚远。
葛祖方∶治痞块疮毒，追风理气，逐疫肺痈。
乳痈初起∶百草镜∶用玉如意草一两，白酒煎，饱肚时服，初起者二服即消，成脓者两
剂必
溃，已溃者三服易敛，疼痛者服之能止。
乳痈疔疮∶救生苦海∶白花如意草，一名银剪刀，生田野山间，较人家种者叶狭花小，
捣汁
服之，渣敷患处。
儿背生泡∶集验∶小儿背上起白泡，累如缀珠，一二日即破，脓血外流，痒甚，一处方
好，
一处又起。用如意草捣烂敷之，长巾缚定，一夜而愈。
脚上生疮∶集验∶治脚上生疮，乱孔如蜂窝者，用如意草捣烂敷之。或用干如意草为末，
鸡子清调敷亦可。
按∶此种又与地丁草不同，地丁小而此种大；地丁叶深绿；此叶浅绿。有云家种如意草，
亦有白花者，乃真玉如意。野生者，仍是银剪刀耳。性劣，不若家种者良。

Sifang Ruyi Cao (Four-Directional Ruyi Grass)
Also known as Jiantou Cao (Arrow Grass), Jiandao Cao (Scissors Grass), and Dafeng Cao (Great Wind Grass). *Baicao Jing* records: It grows in mountains or on field ridges, coming in purple and white varieties. The one with purple flowers is named Jin Jiandao (Golden Scissors), and the one with white flowers is named Yin Jiandao (Silver Scissors); for medicinal use, the white-flowered variety is superior. Its leaves are no different from those potted at home, except that the flowers are smaller, and the leaves are narrower, longer, and slightly pointed at the tip.
Zhao Xuemin notes: Ruyi Cao found in the wild has leaves that are pointed at the top and round at the bottom, with a deep cyan color, showing little difference from cultivated varieties, except that the leaf color is slightly darker green. Its flowers belong to the same category but a different species; its nature and efficacy are not significantly different.
Ge Zufang records: Treats pi kuai (abdominal masses), chuang du (sores and toxins), expels wind and regulates qi, dispels epidemic pathogens, and treats fei yong (lung abscess).
For early-stage ru yong (mastitis): *Baicao Jing* records: Use 1 liang of Yu Ruyi Cao (Jade Ruyi Grass), decocted in bai jiu (white wine). Take when the stomach is full. For early-stage cases, two doses will cause resolution; for cases where pus has formed, two prescriptions will lead to rupture; for already ruptured cases, three doses facilitate easy healing; it also relieves pain.
For ru yong and ding chuang (furuncle): *Jiusheng Kuhai* records: Baihua Ruyi Cao (White-flowered Ruyi Grass), also known as Yin Jiandao (Silver Scissors), grows in fields and mountains. Its leaves are narrower and flowers smaller than cultivated varieties. Crush and take the juice internally; apply the dregs externally to the affected area.
For blisters on a child's back: *Jiyan* records: White blisters appear on a child's back, accumulating like beads. They rupture within one to two days, discharging pus and blood, causing severe itching. As one area heals, another appears. Crush Ruyi Cao and apply as a poultice; bind firmly with a long cloth strip. Healing occurs overnight.
For sores on the feet: *Jiyan* records: To treat sores on the feet presenting with chaotic holes resembling a honeycomb, crush Ruyi Cao and apply as a poultice. Alternatively, grind dried Ruyi Cao into powder, mix with ji zi qing (egg white), and apply.
Note: This herb differs from Di Ding Cao (Viola Herba). Di Ding Cao is smaller, while this herb is larger; Di Ding Cao has dark green leaves, whereas this herb has light green leaves. Some claim that cultivated Ruyi Cao with white flowers is the true Yu Ruyi (Jade Ruyi). Wild varieties remain Yin Jiandao (Silver Scissors). Their medicinal quality is inferior to cultivated varieties.
For infant smallpox accompanied by急促 breathing (qi ji): Liu Shi Yan Fang (Liu’s Verified Formula) records: Baihua Di Ding (White-flowered Viola), regardless of quantity, decocted in water and taken orally, immediately stops急促 breathing.
Yan Tian Huo Dou (Summer Heat Fire Smallpox), Liu Shi Yan Fang: During summer months, smallpox may present as "fire smallpox," characterized by redness all over the body. Crush Baihua Di Ding (White-flowered Viola) to extract juice, and take mixed with bai jiu (white wine)...
