In addition to the above two kinds, there are roots of the same plant, Fangfeng, which are also used as Peucedanum praeruptorum in Shaanxi, Hebei, Henan, Guangxi and other places. The commodity is called "Peucedanum rigidum". See the article "Stone windproof".
The chemical composition of Peucedanum purpurea root contains coumarin: Peucedanum glycoside is about 1.6 1%. It also contains spongiosol, mannitol and volatile oil. The main components of volatile oil are wormwood and limonene. The root of Peucedanum praeruptorum contains Peucedanum praeruptorum A, B, C and D.
Pharmacological action The method of collecting tracheal mucus secretion from anesthetized cats proves that oral administration of Peucedanum chinense 1 g/kg can significantly increase the secretion of respiratory mucus, so it has expectorant effect. Injecting 1% iodine solution1~1.5 ml into the pleural cavity of cats caused cough, and taking 0.8 ~ 2 g/kg decoction had no obvious antitussive effect. Peucedanum (see "Fangfeng" article) has antibacterial and antifungal effects.
Processing Radix Peucedani: clean impurities, remove reed, wash the soil, soak it slightly, take it out, moisten it thoroughly, slice it and dry it. Honey Peucedanum: Take Peucedanum slices, mix well with refined honey and appropriate amount of boiling water, slightly stuffy, stir-fry in a pot with slow fire until it doesn't stick to your hands, take them out and let them cool. (Each Peucedanum Peucedanum slice 100 kg, 20 kg of refined honey)

Famous experts discuss ① "Compendium": "Qianhu is the medicine of Taiyin and Yangming in hands and feet, which is different from that of Chaihu whose pure yang rises and enters Shaoyang and Jueyin. It is good at lowering qi, so it can treat phlegm heat, asthma and cough, nausea and vomiting. Under the qi, the fire will drop, and the phlegm will also drop. Therefore, it has the achievement of promoting the old and bringing forth the new, and it is necessary to take medicine for phlegm. "Tao Hongjing said that he and Bupleurum have the same merits, although the treatment and syndrome are the same, but the main body is different."
(2) "Materia Medica": "Peucedanum, a medicine for dispelling cold, purifying exterior evils, warming lung qi and eliminating phlegm and cough. Such as cold syndrome, cough, phlegm and asthma, heavy voice and strong qi, this evil is also in the lung meridian; Typhoid syndrome, headache, aversion to cold, fever and bone pain, this evil is also in the bladder meridian; The chest and hypochondrium are full and the qi knot is uncomfortable, and this evil is also divided into the middle diaphragm. Pregnancy fever, unwilling to eat; Children have fever, and the rash is shapeless; "Your Excellency's phlegm is hot, and he resists qi. This evil spirit is trapped in the phlegm, and you can cure it with Qianhu." "Luo Yijin, Peucedanum chinense, Rhizoma Pinelliae, Rhizoma Arisaematis, Fructus Aurantii Immaturus, Fructus Aurantii Immaturus, dry phlegm, Fritillaria, Radix Ophiopogonis, Coptidis Rhizoma and Trichosanthes Radix, all have their own differences."
(3) "Herbal Tongxuan": "Peucedanum, lung and liver medicine also. Dispel wind and heat, eliminate phlegm and lower qi, promote appetite and digestion, stop vomiting and asthma, relieve cough and prevent miscarriage, and stop children from crying at night. Bupleurum chinense and Peucedanum chinense are both wind medicines, but Bupleurum chinense mainly rises and Peucedanum chinense mainly falls to different ears. All kinds of skills are the effect of searching for wind and lowering qi, and the liver and gallbladder are patients with wind and phlegm, so there is nothing else to treat them. Avoid fire. "
