多生长在阴冷的山崖和险峻的裂缝处。它的叶子长的接近一尺长，宽一寸多，质地柔韧像皮革一样，背面有黄色的绒毛，所以名叫石苇。（李时珍《本草纲目》）
味苦，性平，气微寒。主治劳热邪气，癃闭不通。（《神农本草经》）能止烦渴、降逆气，通利膀胱胀满，补益五劳。
安五脏。
[论] 石苇生长在石头旁边以及阴冷的山崖险缝中，汲取的阴气最为纯正，似乎与肾气有直接的联系，以此作为补益后发挥通利的作用，因此统管各种淋证（小便不利）。
[修治] 刷去背面的黄毛，以免刺激肺部引起咳嗽，并且应当去掉茎梗，微微炙烤后使用。
有地朕血、见愁草、血竭、血风草等名称。贴地生长，细小柔弱且蔓延铺开，茎是红色的，折断后有汁液流出，叶子呈青紫色，夏季茂盛，六月开红花，结细小的果实，取苗和种子入药。另外络石也叫做地锦，属于藤蔓类植物，与此同名但不同物。（苏颂《本草图经》引禹锡语）
气味苦平。主治心气。（“平”即是辛，火得到金气，就能宅居水而化为血。）通流血脉，也可以治疗气病。
附方：妇人血崩，用草血竭嫩者蒸熟，用油盐姜腌制食用，饮酒一二杯送下；或者阴干研为粉末，用姜酒调服一二钱，即可止血。血淋，用血风草，井水研磨后服用，三次即愈。
[论] 地锦蔓延生长，茎赤红，叶子更呈青紫色，观察它在夏季茂盛，六月开红花，结细实，且味道苦，似乎得火之化气。
五六月份，在湿地及腐木上突然发生，紫褐色，中空虚浮，弹它会有粉尘飞出，大的如斗大，重的不超过一两钱。秋季采收。
味辛，气平，其体质轻虚，是上焦肺经的药物。清肺散血热解毒，治疗时疫引起的剧烈头痛，以及喉痹咽疼。（去掉外皮膜，马勃一味研为末，沙……吐涎血即……）
[论] 马勃本源于腐化之气，当五六月火土极盛之时，万物化生的气息已至极点，此时腐化之气也乘着这个时机……
[修治] 用生布张开，将马勃在上面摩擦，下面用盘子承接收集粉末使用。
Shiwei (Pyrrosiae Folium) grows mostly in shady cliffs and dangerous crevices. Its leaves are nearly one chi long, over one cun wide, soft and tough like leather, with yellow hairs on the back, hence named Shiwei. (Benhu)
Bitter in taste, neutral in nature, slightly cold in qi. It treats labor-heat and pathogenic qi, strangury with inability to urinate. (Shennong Bencao Jing) It stops irritability, directs rebellious qi downward, unblocks fullness of the Bladder, tonifies the five labors, and calms the five Zang organs.
[Discussion] Shiwei grows beside stones and in shady cliffs and dangerous crevices, obtaining the yin qi most purely. It seems to have an immediate connection with Kidney qi, using tonification as a means for unblocking. Thus, it governs all types of strangury (Lin syndrome).
[Preparation] Brush off the yellow hairs to avoid irritating the lungs and causing coughing. The stems should also be removed. Use after slight roasting.
It has various names such as Di Zhen Xue, Jian Chou Cao, Xue Jie, and Xue Feng Cao. It spreads along the ground, thin and weak, creeping and spreading. The stems are red, exuding juice when broken, and the leaves are greenish-purple. It flourishes in summer, blooms red flowers in the sixth lunar month, and bears small fruits. The seedlings and seeds are used. Additionally, Luan Shi (Trachelospermi Caulis et Folium) is also called Di Jin; it belongs to the vine category but is a different substance sharing the same name. (Yuxi)
The flavor is bitter and neutral. It treats Heart qi. ("Neutral" implies acridity; Fire receiving Metal qi can reside in Water and transform into Blood.) It promotes the flow of blood vessels and can also treat Qi disorders.
Prescription: For uterine bleeding (Xue Beng), steam tender Ca Xue Jie, pickle with salt, oil, ginger, and eat. Take with one or two cups of wine to stop bleeding. Or dry it in the shade, grind into powder, and take one or two qian mixed with ginger wine to stop bleeding immediately. For hematuria (Xue Lin), use Xue Feng Cao, rub with well water, and drink. Three doses will cure it.
[Discussion] Di Jin spreads with red stems and greener purple leaves. Observing its flourishing in summer, blooming red flowers in the sixth month, bearing small fruits, and having a bitter taste, it seems to derive from the transformation of Fire.
In the fifth and sixth lunar months, it suddenly appears on wet soil and rotting wood. It is purplish-brown, hollow and floating; when flicked, dust comes out. Large specimens may be as big as a dou, weighing no more than one qian. Harvest in autumn.
Acrid in taste, neutral in nature. Its substance is light and void; it is a herb for the Upper Jiao Lung Meridian. It clears the Lungs, disperses blood heat, and resolves toxicity. It treats epidemic severe headache and throat obstruction (Hou Bi) with sore throat. (Remove the membrane. Ma Bo alone, ground into powder... spitting saliva and blood...)
[Discussion] Ma Bo originates from the qi of putrefaction. When Fire and Earth are at their peak in the fifth and sixth lunar months, the qi of generation and transformation of all things is at its extreme. At this time, the qi of putrefaction also takes advantage of this momentum...
[Preparation] Spread raw cloth open, rub the Ma Bo on it, and catch the powder in a plate below. Use the powder.
