【爵床】
味咸，性寒，无毒。主治腰脊疼痛，无法躺卧在床上，俯身和仰起身体困难，清除热邪，可以制作成洗浴用的汤剂。生长在汉中地区的山谷及田野中。
《唐本草》注解说：这种草形状像香薷，叶子长而大，有的像荏（苏子）那样细小。生长在水泽、熟田以及道路旁边，对于治疗血胀和气逆非常有效。又主治杖打造成的疮伤，将汁液涂抹在患处，立刻就能痊愈。俗名叫赤眼老母草。现在参考其他版本的注释说：现在的人叫它香苏。
【井中苔及萍】
性大寒。主治漆疮、热疮、水肿。井中的蓝草（菘蓝），能解除野葛、巴豆等各种毒物引起的中毒。
陶隐居说：废弃的井中多生长苔藓、浮萍，以及在砖土间生长的杂草、菜蓝（菘蓝），既然有解毒功效，在井中生长的更为优良。不应该另外再有一种名字叫“井中蓝”。井底的泥土极冷，也能治疗烫伤和火灼伤。井华水（清晨第一次汲取的井水），又在服食炼制的方药中使用。臣禹锡等人谨慎地按照《蜀本》记载说：井中的苔藓和浮萍，味道苦。日华子说：无毒。
《图经》的文字内容已收录在海藻条目下。
【茅香花】
味苦，性温，无毒。主治中恶（突然感受秽浊之气导致的急症），温暖胃腑以停止呕吐，治疗心腹部的冷痛。其苗、叶可以煮成洗浴用的汤剂，驱除邪气，使人身带香气。生长在剑南道各州。它的茎、叶呈黑褐色，花是白色的，这就不是白茅香了。（今附）
臣禹锡等人谨慎地按照陈藏器的说法说：茅香，味甘，性平。生长在安南，形状像茅根。日华子说：白茅香的花塞入鼻孔，可治疗因长期灸疗导致伤口不愈合的情况，以及刀箭创伤，能止血并止痛。煎汤服用可止吐血、鼻出血。
《图经》说：茅香花，生长在剑南道各州，现在陕西、河东、京东等地的州郡也有生长。三月生苗，形状像大麦。五月开白花，也有开黄花的。有的结籽，有的不结籽，都在正月、二月采集根部，五月采集花朵，八月采集苗叶。茎、叶黑褐色而花白的，名叫白茅香。
陈藏器说：白茅香，味甘，性平，无毒。主治恶气，使人身上香气美好，煮后服用，主治腹部冷痛。生长在安南，形状像茅根，用来做洗浴。
海药说：谨按《广志》记载：生长在广南山谷，味甘，性平，无毒。主治小儿全身疮疡，用桃叶一起煮后洗浴，配合各种名贵的香料非常奇妙，尤其胜过从海外运来的药材。
《肘后方》：治疗热淋。取白茅根四斤切碎，用水一斗五升，煮取五升，冷却后，再温热饮用。每天分三次服用。又一个方子：治疗竹木刺扎在肉中出不来。取白茅根烧成末，用脂膏调和涂抹，也能治疗因风邪导致的肿胀。
《衍义》说：茅草，花白，根像茅草，但明亮洁净且长，都可以制作成洗浴用的汤剂，同本草药材一起使用尤其好。仍然加入印香中，配合香附子使用。
[Juechuang (Stemona Root)]
Salty in flavor, cold in nature, non-toxic. It primarily treats pain in the waist and spine, inability to lie on a bed, difficulty in bending forward or extending backward, clears heat, and can be used as a decoction for bathing. Grows in valleys and fields of Hanzhong.
The *Tang Bencao* annotation states: This herb resembles Xiangru (Elsholtzia splendens), with long and large leaves, sometimes fine like Ren (Perilla frutescens). It grows in marshes, cultivated fields near roadsides, and is highly effective in treating blood distension and qi rebellion. It also treats whip wounds; applying its juice leads to immediate healing. Commonly known as Chiyan Laomu Cao (Red-eyed Old Mother Grass). Current annotations from other editions state that people now call it Xiangsu.
[Jingzhong Tai Ji Ping (Moss and Duckweed in Wells) & Jingzhong Lan (Isatis Leaf grown in Wells)]
Great cold in nature. Treats lacquer dermatitis, heat sores, and edema. Jingzhong Lan (Isatis Leaf grown in wells) neutralizes poisons from Yege (Gelsemium elegans), Badou (Croton tiglium), and other toxic substances.
Tao Hongjing stated: Abandoned wells often contain moss, duckweed, and weeds/vegetable Isatis growing among bricks and soil. Since they possess detoxifying properties, those growing in wells are superior. There should not be a separate species named "Jingzhong Lan." Mud at the bottom of wells is extremely cold and also treats scalds and burns. Jinghua Shui (well water drawn at dawn) is also used in preparation methods for ingested refined medicines. Ministers Yu Xi et al., carefully according to the *Shu Ben*, recorded: Moss and duckweed in wells have a bitter taste. Rihua Zi stated: Non-toxic.
The text of the *Tu Jing* is included under the entry for Haizao (Sargassum).
[Maoxiang Hua (Flower of Cyperus aromaticus)]
Bitter in flavor, warm in nature, non-toxic. Treats Zhong'e (sudden illness caused by foul miasma), warms the stomach to stop vomiting, and treats cold pain in the heart and abdomen. Its seedlings and leaves can be boiled into a bath decoction to ward off evil qi and make the body fragrant. Grows in various prefectures of Jiannan Dao. Its stems and leaves are dark brownish-black, and flowers are white; this is not Baimao Xiang (White Sedge Flower). (Currently appended)
Ministers Yu Xi et al., carefully according to Chen Cangqi, stated: Maoxiang has a sweet flavor and neutral nature. It grows in Annan and resembles Maogen (Rhizoma Imperatae). Rihua Zi stated: The flower of Baimao Xiang inserted into the nostrils treats ulcers that fail to heal after prolonged moxibustion, as well as knife and arrow wounds, stopping bleeding and pain. Decoction stops hematemesis and epistaxis.
The *Tu Jing* states: Maoxiang Hua grows in various prefectures of Jiannan Dao; it is now also found in Shaanxi, Hedong, and Jidong prefectures. Seedlings emerge in March, resembling barley. White flowers bloom in May, though some have yellow flowers. Some produce seeds, others do not. Roots are harvested in January and February, flowers in May, and seedlings in August. Those with dark brownish-black stems and leaves and white flowers are named Baimao Xiang.
Chen Cangqi stated: Baimao Xiang has a sweet flavor, neutral nature, and is non-toxic. It treats malignant qi, making the body fragrant. Boiled and consumed, it treats internal cold pain. It grows in Annan, resembling Maogen, and is used for bathing.
Haiyao stated: According to the *Guang Zhi*: It grows in the mountains and valleys of Guangnan, has a sweet flavor, neutral nature, and is non-toxic. It treats generalized sores in children; boiling it with peach leaves for bathing, combined with various precious aromatics, is very miraculous and superior to imported goods.
The *Zhou Hou Fang*: To treat Re Lin (hot strangury). Take four jin of Baimaogen, chop it, boil in one dan five sheng of water until reduced to five sheng. Cool it, then drink it while warm. Take three times daily. Another prescription: For bamboo or wood splinters stuck in flesh. Burn Baimaogen to ash, mix with fat/grease, and apply externally. It also treats swelling caused by wind.
The *Yanyi* states: Mao grass has white flowers and roots like sedge, but bright, clean, and long. All parts can be used for bath decoctions; using them together with Bencao is particularly good. It is still incorporated into Yinxiang (Indian incense), combined with Xiang Fuzi (Aconitum carmichaelii lateral root prepared with aromatics).
