百病多兼有痰，故病以化痰为先。善治痰者，兼治气，气顺则痰利。痰脉浮滑者宜降；
浮实者宜吐，沉小者不宜吐，恐虚故也。凡治痰症，不可全用利药，过使脾气虚弱，则痰反
易生而多。若脾虚生痰者，用健脾燥湿，便要利补兼用。陈皮、白术为佐也。痰乃秽浊之物，

百病多兼夹痰邪，因此治疗疾病应以化痰为首要任务。善于治疗痰证的人，会兼顾调理气机，气机顺畅则痰液易于排出。脉象浮滑的痰证适宜用降气法；脉象浮而实大的适宜用涌吐法；脉象沉小的不适宜用涌吐法，因为担心损伤正气。凡是治疗痰证，不可完全使用利水渗湿的药物，过度使用会使脾气虚弱，反而容易生痰且痰量增多。如果是脾虚生痰的情况，应采用健脾燥湿的方法，并且要补益与通利兼顾。方中可佐以陈皮、白术。痰属于秽浊之物，适宜使用竹沥达痰丸（能够引导痰液从大肠排出，不损伤元气，效果神奇）。
半夏二两（经过七次炮制，用姜汁浸泡透彻，晒干后切片，在瓦片上焙熟）；白茯苓、陈皮（去除白色内皮，洗净）、炙甘草、人参各一两；大黄（用酒浸泡透彻后晒干）、酒黄连各三两；沉香五钱；礞石一两（取焰硝一两与礞石混合均匀，放入银罐内，用瓦片盖好，用盐泥封固，晒干后置于炭火中煅烧至金黄色）。
以上药物研为细末，加入半碗竹沥、两钟姜汁，放入锅内熬煮一刻钟，然后将药粉与汁液混合捣匀，盛放在磁罐中，晒干。仍然按照前面的方法，用竹沥和姜汁再次捣晒七次，最后用竹沥调和制成如小豆大小的丸剂。每次服用一百丸，饭后用米汤送服。（出自《万病回春》）
风痰引起的头晕（伴有呕吐逆气、目眩、面色青黄、脉弦等症状）：
半夏、生南星、寒水石各一两；天麻五钱；雄黄三钱；小麦面三两。
研为细末，用水调和成饼状，水煮至浮起，捞出后捣碎制成丸剂。每次服用五十粒，用姜汤送服，效果极佳。（出自《古法机要》）
寒痰引起的气喘：
取一片青橘皮展开，放入一粒巴豆，用麻线扎紧，在火上烧至存性（保留药材部分药效），研为细末。用姜汁和酒调服。天台人李翰记载，此方能治疗莫秀才的口喘病，服药后立即停止。（出自《张果医说》）
痰火证：
天花粉一斤，切成片，第一次用藜芦汁一钟拌和后晒干；第二次用萝卜汁一钟拌和后晒干；第三次用竹沥一钟拌和后晒干。研为细末，每次服用一钱，用好茶送服。（出自《怀德堂录》）
另一种用法：桑白皮四两、款冬花二两、薄荷四两、甘草二两、芽茶四两、陈香橼四两、萝卜子五钱、杏仁五钱、鹅管石五钱，用水和白糖制成丸剂服用。（出自《卫生备要》）
Hundred diseases often involve phlegm; therefore, treating disease should prioritize resolving phlegm. Those skilled in treating phlegm simultaneously regulate Qi (vital energy); when Qi flows smoothly, phlegm is easily discharged. For phlegm with a floating and slippery pulse (Fuping Huamai), descending methods are suitable; for a floating and excess pulse (Fushi Mai), emetic methods are suitable; for a deep and small pulse (Chenxiao Mai), emetic methods are not suitable due to the fear of damaging healthy Qi (Zhengqi). In general, treating phlegm disorders should not rely entirely on diuretic/damp-draining herbs, as excessive use weakens Spleen Qi (Pipi), which may cause phlegm to be generated more easily and abundantly. If phlegm is generated due to Spleen deficiency, one should employ methods to strengthen the Spleen and dry dampness (Jianpi Zaoshi), combining tonification with draining. Chenpi (Tangerine Peel) and Baizhu (Atractylodes Macrocephala Rhizome) serve as adjuncts. Phlegm is a turbid substance; it is suitable to use Zhuli Datan Wan (Bamboo Juice Pill for Expelling Phlegm, capable of guiding phlegm out through the Large Intestine without damaging Yuan Qi [Original Qi], with miraculous effects).
Banxia (Pinellia Tuber) 2 liang (processed seven times, soaked thoroughly in Shengjiang juice [Fresh Ginger Juice], dried, sliced, and roasted on tiles); Baifuling (Poria) 2 liang; Chenpi (Tangerine Peel, white pith removed, cleaned) 2 liang; Zhigancao (Prepared Licorice Root) 1 liang; Renshen (Ginseng Root) 1 liang; Dahuang (Rhubarb Root and Rhizome, soaked in wine until penetrated, then dried) 3 liang; Jiu Huangqin (Scutellaria Root processed with wine) 3 liang; Chenxiang (Aquilaria Wood) 5 qian; Mengshi (Calamine) 1 liang (mixed evenly with 1 liang of Yanxiao [Saltpeter], placed in a silver jar, covered with a tile, sealed with salt mud, dried, and calcined in charcoal fire until golden yellow).
The above ingredients are ground into fine powder. Add half a bowl of Zhuli (Bamboo Sap) and two zhong of Shengjiang juice (Fresh Ginger Juice), boil in a pot for one ke (approx. 15 minutes), then mix the powder with the liquid and pound thoroughly. Store in a porcelain jar and dry. Repeat the pounding and drying process seven times using Zhuli and Shengjiang juice as before. Finally, mix with Zhuli to form pills the size of small beans. Take 100 pills per dose, washed down with rice water after meals. (From *Wanbing Huichun*)
Wind-phlegm causing dizziness (accompanied by vomiting/nausea, vertigo, greenish-yellow complexion, and wiry pulse [Xianmai]):
Banxia (Pinellia Tuber) 1 liang; Sheng Nanting (Raw Arisaema Rhizome) 1 liang; Hanshuishi (Calcitum) 1 liang; Tianma (Gastrodia Rhizome) 5 qian; Xionghuang (Realgar) 3 qian; Xiaomai mian (Wheat flour) 3 liang.
Grind into powder, mix with water to form cakes, boil in water until they float, remove, pound into pills. Take 50 pills per dose, washed down with ginger soup. Extremely effective. (From *Gufa Jiyao*)
Cold-phlegm causing asthma/wheezing:
Take one piece of Qingjupi (Green Tangerine Peel), unfold it, insert one Badou (Croton Seed), tie tightly with hemp thread, roast over fire until "preserving nature" (charred but retaining efficacy), grind into powder. Mix with Shengjiang juice (Fresh Ginger Juice) and wine to take. Li Han from Tiantai recorded that this cured Scholar Mo's immediate-onset asthma. (From *Zhangguo Yishuo*)
Phlegm-fire disorder:
Huafen (Trichosanthes Root) 1 jin, sliced. First, mix with one zhong of Lizi (Veratrum Juice) and dry in the sun; second, mix with one zhong of Luobozhi (Radish Juice) and dry in the sun; third, mix with one zhong of Zhuli (Bamboo Sap) and dry in the sun. Grind into powder. Take 1 qian per dose, washed down with good tea. (From *Huaide Tanglu*)
Another prescription: Sangbaipi (Mulberry Root Bark) 4 liang; Kuandonghua (Farfara Flower) 2 liang; Bohe (Mint Herb) 4 liang; Gancao (Licorice Root) 2 liang; Yacha (Sprouted Tea Leaves) 4 liang; Chen Xiangyuan (Dried Citron Fruit) 4 liang; Bobzi (Radish Seed) 5 qian; Xingren (Apricot Seed) 5 qian; Eguan Shi (Avicenniae Fructus or similar mineral) 5 qian. Form pills with water and white sugar. (From *Weisheng Beiyao*)
