治疗咳逆上气（咳嗽气喘，气机上逆），喘渴（肺虚挟火），喉痹（咽喉肿痛闭塞），肺痿（肺部萎弱不用之病）肺痈（肺部化脓性感染），咳吐脓血。是治疗咳嗽的要药（燃烧烟雾通过管状物吸入也有效。百合、款冬花等分制成蜜丸，名为百花膏，治疗咳嗽痰血。凡是阴虚劳嗽，通用款冬花、紫菀、百部、百合、沙参、生地黄、麦冬、五味子、知母、黄柏、黄芩、白芍。如果内热骨蒸，加牡丹皮、地骨皮。若咳嗽又兼腹泻的，是肺移热于大肠，脏腑俱病。咳嗽且发热不止的，是阴虚火炎，都难治），寒热虚实，皆可施用（《本草汇》说：隆冬独秀，先春开放，得肾之体，先肝之用，所以是温肺理嗽的最佳药物。大抵咳嗽必因寒，寒为冬气，入肺为逆。款冬花不是肺家专药，乃使肺邪从肾顺流而出。肺恶寒。郭佩兰，着《本草汇》）。十一、二月开花如黄菊，微见花、未舒者良（生河北关中，世多以枇杷蕊伪之）。拣净花，甘草水浸一宿，曝用。得紫菀良。杏仁为使。恶皂荚、硝石、玄参。畏黄 、贝母、连翘、麻黄、青葙、辛夷（虽畏贝母，得之反良）。

Moisten the lungs, clear heat, and stop coughing.
Pungent, warm, pure yang. Clears heat and moistens the lungs, resolves phlegm and relieves irritability. Calms fright and brightens the eyes.
Treats cough with rebellious qi (cough and asthma with upward rushing of qi), wheezing and thirst (lung deficiency with constrained fire), throat obstruction (swelling and blockage of the throat), lung flaccidity disease (a condition where the lungs become weak and atrophic), lung abscess (purulent infection of the lungs), and coughing up pus and blood. It is an essential herb for treating cough (burning it to inhale the smoke through a tube is also effective. Equal parts of Baihe [Lily Bulb] and Kuantonghua [Flos Tussilaginis] made into honey pills, named Baihua Gao [Hundred Flower Paste], treats cough with hemoptysis. For yin-deficiency consumptive cough, Kuantonghua, Ziwan, Baibu, Baihe, Shashen, Shengdihuang, Maidong, Wuweizi, Zhimu, Huangbai, Huangqin, and Baishao are commonly used together. If there is internal heat with bone-steaming fever, add Mudanpi and Digupi. If cough is accompanied by diarrhea, it indicates heat transferred from the lung to the large intestine, affecting both zang and fu organs. If cough persists with continuous fever, it indicates yin deficiency with flaming fire; both conditions are difficult to treat). It can be applied in cases of cold, heat, excess, and deficiency (Bencao Hui [Compendium of Materia Medica] states: Blooming uniquely in deep winter and before spring, it embodies the nature of the Kidney and utilizes the function of the Liver first, thus making it the best herb for warming the lungs and regulating cough. Generally, cough arises from cold; cold is the qi of winter, and entering the lung causes rebellion. Kuantonghua is not exclusively a lung herb, but rather facilitates the flow of lung pathogenic factors out through the kidney. The lung dislikes cold. Guo Peilan, author of Bencao Hui). Flowers bloom in the 11th and 12th lunar months like yellow chrysanthemums; those slightly visible and not fully opened are superior (Grows in Guanzhong, Hebei; often counterfeited with Loquat stamens in the market). Select clean flowers, soak in Licorice water overnight, and dry in the sun. Works well with Ziwan. Xingren acts as an assistant. Clashes with Zaojiao, Xiaoshi, and Xuanshen. Fears Huangjing, Beimu, Lianqiao, Mahuang, Qingxiang, and Xinyi (Although it fears Beimu, combining them yields good results).
Moisten the lungs, clear fire.
Pungent and warm to moisten the lungs, bitter and warm to direct qi downward. Tonifies deficiency, regulates the middle, resolves phlegm, and stops thirst.
Treats cold-heat knotting of qi, cough with rebellious qi, and coughing up pus and blood (specifically treats bloody phlegm, considered a sacred medicine for blood consumption disease), deficiency heat in the Lung meridian, and pediatric convulsions and epilepsy (also deficiency with heat). It can open throat obstruction and expel foul saliva/phlegm, but due to its pungent dispersing and slippery nature, it should not be used alone or in excessive amounts (Bencao Hui states: Bitterness can reach downwards, pungency benefits Metal [Lung], thus it stops vomiting blood and protects the lungs, serving as a premier agent. Although it enters the highest region, it excels at reaching downwards, allowing qi transformation to reach the Zhou Du [Bladder], promoting free urination, a fact unknown to many. Li Shicai said: Pungent yet not drying, moistening yet not cold, tonifying yet not stagnant, it is truly a gentleman of gold and jade. Without frequent use or exclusive application, rapid effects cannot be achieved. Zhou Du refers to the Bladder]).
Roots with nodes, purple in color, moist and soft are superior (Often counterfeited with Plantago roots and Inula roots, leading to misdiagnosis and harm). Remove head and whiskers, soak in honey water, and bake for use. Kuantonghua acts as an assistant. Clashes with Tianxiong, Qumai, Ben Cao, and Yuanzhi. Fears Yinchen. The white variety is named Wan (Shizhen stated: Purple enters the Blood aspect, white enters the Qi aspect).
