Semen Lepidii et Descureniae (Tingli, 葶苈), grows in flatlands near cities, marshes, and fields. Currently, it is found in all prefectures of Jingdong, Shaanxi, and Hebei, with the produce from Caozhou being superior. In early spring, its seedlings and leaves emerge, reaching a height of six or seven cun, resembling Shepherd's Purse (Jicai, 荠); the root is white, and the branches and stems are green; flowers bloom in the third lunar month, slightly yellow; pods form, and the seeds are flat, small like broomcorn millet but slightly longer, and yellow. The fruits are harvested after the Start of Summer (Lixia, 立夏) and dried in the sun. *Yueling* states: "In the first month of early summer, delicate grasses die." Both Xu Shen and Zheng Xiang's annotations clarify that "delicate grass" refers to plants such as Shepherd's Purse (Jicai, 荠) and Semen Lepidii et Descureniae (Tingli, 葶苈). This herb withers and dies by summer, hence it is harvested at this time. Zhang Zhongjing treated Lung Abscess (Fei Yong, 肺痈) manifesting as wheezing and inability to lie down, using Tingli Dazao Xiefei Tang (Cocklebur and Jujube Decoction to Drain the Lungs) as the primary formula. The Semen Lepidii et Descureniae (Tingli, 葶苈) is stir-fried until yellow, pounded into powder, and formed into pills the size of bullet seeds. For each dose, take twenty Jujubes (Dazao, 大枣), add three sheng of water, decoct to obtain two sheng, then insert one pill-sized portion, continue decocting to obtain one sheng, and administer in a single dose. It also treats Zhi Yin (Branchy Fluid Retention, 支饮) causing dyspnea. Cui Zhiti's prescription treats ascending Qi and cough, prolonged breathing difficulty preventing lying down, generalized edema, facial edema alone, or pedal edema alone. Take three sheng of Semen Lepidii et Descureniae (Tingli Zi, 葶苈子), gently roast over low fire, pound and sieve into a powder. Soak in five sheng of clear wine for seven days in winter or three days in summer. The initial dose is the size of a peach pit, taken three times daily and once at night; in winter, twice daily and twice at night. Adjust according to the patient's strength, aiming for mild purgation of one or two bowel movements. If the condition is acute and critical, do not wait for the full soaking period; the juice may be extracted through fine silk gauze and administered immediately. Semen Lepidii et Descureniae (Tingli, 葶苈) has a single stem growing upward, with pods emerging from the leaf tips; the pods are thick and short. There is another variety, Goujie Grass (Goujie Cao, 苟芥草), whose leaves near the base have an unusual shape, producing long and slender pods. These two varieties must be distinguished during collection. Additionally, *Qie Zhong Fang* describes a plaster pill for containing in the mouth to treat cough: use one liang of Semen Lepidii et Descureniae (Tingli Zi, 葶苈子) from Caozhou, roasted on paper until black; one liang of Rhizoma Anemarrhenae (Zhimu, 知母); one liang of Fritillariae Thunbergii Bulbus (Beimu, 贝母). Pound and sieve these three substances together. Add half a liang of jujube pulp and one and a half liang of melted rock sugar, mix into the medicine, and form into pills the size of bullet seeds. Each dose consists of one pill wrapped in new cotton, held in the mouth, and slowly swallowed with saliva. Severe cases require no more than three pills. Physicians today also frequently use this method.
