(Wei Xian) possesses the functions of promoting circulation, dispelling wind, and detoxifying.
Bitter in flavor and neutral in nature. It treats wind-damp bi syndrome (painful obstruction caused by wind and dampness), Li Jie pain (severe joint pain), fright epilepsy, and Zai Feng (pathogenic wind). It also treats Shu Yong (scrofula and carbuncles). (*Su Wen* records its use for treating Jiu Feng (alcohol-induced wind), characterized by symptoms such as body heat, lethargy, profuse sweating like a bath, aversion to wind, and shortness of breath. The prescription consists of Ze Xie (Alisma Rhizome) and Bai Zhu (Atractylodes Macrocephala Rhizome) each in ten parts, and Wei Xian in five parts, mixed and taken as three finger-crowns after meals.) Also known as Mi Xian, or Lu Xian. (Mi deer and Lu deer belong to the same category. Su Gong stated: People in the south call it Wu Feng Cao, also named Lu Xian Cao, meaning that when a deer is ill, it carries this herb in its mouth, and the illness heals.)
(Ma Lan Zi) refers to the fruit of Ma Lan. It has a drying property and treats Han Shan (cold hernia) and cold accumulation.
Sweet in flavor and warm in nature. It treats lower abdominal hernia pain, cold accumulation within the abdomen, water-type diarrhea, and various other diseases.
(Long Xu Cao) refers to Long Xu Cao. It promotes urination and unblocks strangury.
Bitter in flavor and slightly cold in nature. It treats strangury with urinary retention and burning pain in the urethra. Bai Xi (old woven mats) has similar main indications. Take old, dirty mats measuring one chi by one chi, boil them in water, and drink the decoction.
(Deng Long Cao) refers to Deng Long Cao. It promotes circulation and clears damp-heat.
Bitter in flavor and cold in nature. It eliminates heat, promotes diuresis to remove dampness, clears the lungs and transforms phlegm, relieves irritability and fullness, and promotes urination. (It is effective for treating Huang Bing [jaundice].) It treats Shang Qi cough (cough due to rebellious qi). (The juice can be boiled and drunk, or ground into a paste, or freshly crushed juice can be drunk.) Applied externally to children's Shan Pi (sudden swelling/pain). (Zhu Danxi said: Deng Long Cao, being bitter, can clear damp-heat; being light and ascending, it treats the upper jiao, thus primarily treating hot cough and sore throat. This herb treats hot-phlegm cough, while Fo Er Cao treats cold-phlegm cough. Li Shizhen said: Suan Jiang (Physalis alkekengi) clears heat, thus clearing the lungs and treating cough; it promotes diuresis, thus transforming phlegm and treating pi accumulation. One person suffered from deficiency and fatigue with phlegm and cough; adding this herb to the decoction was very effective.) The roots, stems, flowers, and leaves are all usable. (Leaves applied to moxibustion sores prevent blistering.)
Seeds are sour in flavor and neutral in nature. They have the same efficacy as the roots, stems, flowers, and leaves. (For Tian Pao Shi Chuang [blistering eczema], crush the seeds and apply externally, or grind into powder and mix with oil for external application.)
(Fo Er Cao) refers to Fo Er Cao. It can be used for famine relief.
Sweet in flavor and neutral in nature. It eliminates phlegm and stops cough. (Li Shizhen said: *Bie Lu* states: treats chills and fever, stops cough; Zhang Yuansu states: treats cold cough, referring to the superficial aspect; Hua Shou states: treats hot cough, referring to the root cause. Generally, cold coughs are often due to fire constrained internally with cold affecting externally. Referring to Chen Shi's Experiential Formula: Yi Qi San treats all types of coughs, regardless of duration or time of day. Use twice the amount of Kuan Dong Hua (Tussilago Farfara Flower), half the amount of Fo Er Cao, and two liang of Shu Di Huang (Rehmannia Glutinosa Root prepared with wine). Roast until dry, grind into powder. Take two qian each time, burn it on a stove, inhale the smoke through a tube and swallow. If saliva/phlegm is produced, spit it out. My family once stored this method to treat chronic cough, but doctors failed to cure it. Accidentally, I met a maid in Yuanzhou who used this method, and she was cured after two doses.) Mixed with rice flour to make Qiu Shi (dried grain snacks), which tastes sweet. It is best as food during famine years.
