经》络石条注中有地锦，与此同名，而别是一类也。
经验方治藏毒赤白。地锦草采得后，洗曝干为末，米饮下一钱，立效。
【赤车使者】
味辛、苦，性温，有毒。主治风冷邪气及疰病（一种具有传染性或迁延不愈的疾病），蛊毒（中蛊中毒），症瘕（腹内结块），五脏积气（脏腑之气郁结）。
《唐本草》注云：苗叶类似香薷、兰香草，叶和茎呈红色，根呈紫红色，生长在山谷溪流的背阴处，产于襄州。八月、九月采集根部，晒干。（此条原附于前代本草之后）臣禹锡等人谨按《蜀本图经》记载：根紫色如同茜草根，生长在荆州、襄州的山谷中，二月、八月采集。《药性论》记载：赤车使者，有小毒。能治疗恶风冷气，服用后能使皮肤肌肉润泽，面色红润。

陶隐居说：产于交州、广州，形状扁平。捣碎后混合米投入水中，无论鱼大小，都会浮出水面而死。人用醋涂抹治疗疥疮也有效。《唐本草》注云：现在京城附近称为黄环子，也称为度谷，一名就葛。陶隐居说产于交州、广州，现在交州、广州送入太常寺的正是黄环子，不是其他东西。现在参考别本注云：味苦，性寒。藤本植物，花紫色。
【青苔衣】
味甘，性寒。主治皮肤间的浮热，往来寒热（忽冷忽热），通利小肠和膀胱的气机。生长在房屋背阴处。八月、九月采集。

【地锦草】
味辛，无毒。主治疏通血脉，也可用于治疗气滞。生长在道路附近的田野中，出产于滁州的质量最好。茎叶细弱，蔓延在地面上。茎呈红色，叶呈青紫色，夏季茂盛。六月开红花，结细小的果实。采集苗和种子入药。络石条下的注中有“地锦”，那是藤蔓类植物，虽然名字相同，但类别完全不同。（新定）
《图经》记载：地锦草，生长在滁州及道路附近的田野中。味辛，无毒。主治疏通血脉，也能治疗气滞。其苗叶细弱，像蔓草一样遍布地面。茎呈红色，叶呈青赤色，仲夏时节茂盛。六月开红花，结细小果实。现在的医家采集苗和种子入药。《本经》络石条注中的“地锦”，与此同名，但是另一类植物。
[Chi Che Shi Zhe (Euphorbia humifusa)]
Pungent, bitter, warm in nature, slightly toxic. Primarily treats wind-cold pathogenic factors and Zhu diseases (infectious or lingering diseases), Gu poison (poisoning from worms/venom), Zheng Jia (abdominal masses), and accumulated Qi in the five zang organs.
The Commentary of Tang Ben Cao states: The seedling resembles Xiang Ru (Elsholtzia) or Lan Xiang (Lysimachia), with red leaves and stems, and purple-red roots. It grows in the shade of valleys and streams, produced in Xiangzhou. The roots are harvested in August and September and dried in the sun. (Originally appended to previous materia medica). Minister Yu Xi et al. carefully note according to the Shu Ben Tu Jing: The root is purple like Qian Cao Gen (Rubia cordifolia root), growing in the valleys of Jingzhou and Xiangzhou, harvested in February and August. Yao Xing Lun records: Chi Che Shi Zhe has slight toxicity. It can treat severe wind-cold and cold qi; taking it makes the skin and muscles lustrous and improves complexion.
Lei Gong says: Chi Che Shi Zhe was originally named Xiao Jin Zhi. For use, it should be coarsely crushed. Mix with urine from a seven-year-old boy, steam until dry, then sun-dry. For every five liang processed, use one yi (a unit of volume) of child's urine as the standard.
Slightly toxic. Primarily treats malignant sores and scabies, and kills fish.
Tao Hongjing says: Produced in Jiaozhou and Guangzhou, it has a flat shape. When crushed and mixed with rice thrown into water, all fish, regardless of size, float up and die. Applying vinegar to rub sores is also effective. The Commentary of Tang Ben Cao states: Now called Huang Huan Zi near the capital, also known as Du Gu, or one name Jiu Ge. Tao said it comes from Jiaozhou and Guangzhou; what is now sent to the Taichang Temple from these regions is indeed Huang Huan Zi, not other substances. Current analysis of another commentary notes: Bitter, cold in nature. Vine plant, purple flowers.
[Qing Tai Yi (Roof Moss)]
Sweet, cold in nature. Primarily treats floating heat in the skin, alternating chills and fever, and promotes the Qi mechanism of the small intestine and bladder. Grows in shady places on roofs. Harvested in August and September.
Tao Hongjing says: This is green moss on tile roofs; peel it off and boil for consumption. Current analysis of another commentary notes: Non-toxic. Primarily treats childhood epilepsy-heat and epidemic febrile diseases, relieving restlessness and thirst. Minister Yu Xi et al. carefully note according to the Shu Ben Tu Jing: It is the green moss found in the north shade of old tile roofs.
[Di Jin Cao (Euphorbia humifusa)]
Pungent, non-toxic. Primarily promotes blood circulation and unblocks collaterals; can also be used to treat Qi stagnation. Grows in fields near roads; those produced in Chuzhou are particularly good. The stems and leaves are slender and weak, spreading over the ground. Stems are red, leaves are blue-purple, flourishing in summer. Red flowers bloom in June, bearing small fruits. The seedlings and seeds are collected for use. In the commentary under Luo Shi (Trachelospermum jasminoides), there is a mention of "Di Jin," which refers to vine-like plants; although sharing the same name, they belong to completely different categories. (Newly determined)
Tu Jing states: Di Jin Cao grows in Chuzhou and fields near roads. Pungent, non-toxic. Primarily promotes blood circulation and unblocks collaterals, and also treats Qi stagnation. Its seedlings and leaves are slender, creeping like vines across the ground. Stems are red, leaves are blue-red, flourishing in mid-summer. Red flowers bloom in June, bearing small fruits. Current physicians collect the seedlings and seeds for use. In the commentary of the Ben Jing under the Luo Shi entry, "Di Jin" shares the same name but is a different category.
Empirical formula for treating internal toxin causing dysentery with red and white discharge: After harvesting Di Jin Cao, wash, sun-dry, and grind into powder. Take one qian with rice broth for immediate effect.
