酢浆草，民间称为酸浆。旧籍未记载其产地，只说生长在道路旁边。如今南方低湿之地及人家园圃中多有生长，北方地区也有生长的。叶子像水萍一样，丛生；茎端长有三片叶子，叶间生出细小的黄花，果实为黑色。夏季采集叶片使用。刚长出嫩芽时，小孩多食用它。南方人用它擦拭石器，使其洁白如银。
（音顷）实，旧籍未记载其产地，如今到处都有。北方人种植它以绩麻织布，以及搓打绳索。植株高四、五尺或六、七尺；叶子像苎麻但较薄，花黄色，果实带壳类似蜀葵，里面的种子是黑色的。九月、十月采集果实，阴干后使用，古方中也使用根部。
蒲公草，旧籍未记载其产地，如今各地平原沼泽田园中都有生长。初春生苗，叶子像苦苣菜，有细刺；中心抽出一根茎，茎端开出一朵花，颜色黄如金钱；折断茎部有白色汁液流出，人们也食用它。民间称为蒲公英，语音讹传为仆公罂。用水煮取汁液治疗妇女乳痈，又捣碎外敷疮口，效果都很好。又治疗恶刺及狐尿刺，摘取根茎的白色汁液涂抹患处，只要多涂几次立刻痊愈。此方出自孙思邈《千金方》。其序言中说：我在贞观五年七月十五日夜，因左手中指背面触碰到庭院树木，到早晨便患疼痛难以忍受。经过十天，疼痛日益加深，疮疡日益高肿，颜色像熟透的小豆色。曾听长者论说有此方，于是依此法治疗。手下即愈，疼痛也消除，疮疡随即痊愈，不到十天便恢复如初。杨炎《南行方》也记载了它的疗效。
Oxalis corniculata, commonly known as Suanjiang (sour berry). Old texts do not record its place of origin, stating it grows by the roadside. Currently, it is abundant in low-lying wet areas and home gardens in the south, and also found in some northern regions. The leaves resemble duckweed, growing in clusters; three leaves emerge at the stem tip, with small yellow flowers between the leaves, and black fruits. Leaves are harvested in summer for use. When young and tender, children often eat them. Southerners use it to polish stone vessels, making them white as silver.
Qing Shi (Seed of Oxalis), old texts do not record its place of origin, but it is now ubiquitous. Northerners cultivate it for spinning cloth and twisting ropes. The plant is four to five or six to seven chi tall; leaves resemble ramie but are thinner, flowers are yellow, and fruits have shells similar to Malva verticillata, containing black seeds inside. Fruits are harvested in September and October, dried in the shade for use; ancient prescriptions also utilize the root.
Taraxacum mongolicum, old texts do not record its place of origin, but it is now present in plains, marshes, and fields everywhere. In early spring, shoots emerge; leaves resemble Sonchus oleraceus, with fine spines; a single stem emerges from the center, bearing a flower at the tip, yellow like gold coins; breaking the stem exudes white juice, which people also consume. Commonly called Puying (Dandelion), the name is an erroneous pronunciation of Pugongying. Boiling the plant in water to extract juice treats Ru Yong (breast abscess) in women; crushing and applying it topically to sores is also effective. It also treats "evil thorns" and fox urine thorns; applying the white juice from the roots and stems cures them quickly if applied frequently. This prescription originates from Sun Simiao's Qianjin Fang (Prescriptions Worth a Thousand Gold). The preface states: "In the night of July 15th of the fifth year of Zhen Guan, my left middle finger back touched a tree in the courtyard. By morning, I suffered unbearable pain. After ten days, the pain deepened, and the sore became increasingly swollen, colored like cooked mung beans. Having heard elders discuss this prescription, I followed the treatment. It healed immediately upon application, pain ceased, and the sore recovered. Within ten days, I was fully restored." Yang Yan's Nan Xing Fang (Southern Journey Prescriptions) also records its efficacy.
