味辛，性平，生用微寒，熟用温，有毒。主治伤寒引起的寒热往来，心下痞硬，降逆气，缓解喉咽肿痛，头晕目眩，胸胀咳嗽气逆，腹中鸣响，止汗，消除心腹胸膈间的痰热积结，治疗咳嗽气上逆，心下急痛、坚硬痞块，时行疫病引起的呕吐逆气，消散痈肿，堕胎，治疗萎黄病，使面目容光焕发。生半夏令人呕吐，熟半夏令人通便。使用时需用汤水清洗至滑腻感尽除。又名守田，又名地文，又名水玉，又名示姑。生长于槐里的川谷地带。五月和八月采集根部，晒干。（射干作为其引经药，厌恶皂荚，畏惧雄黄、生姜、干姜、秦皮、龟甲，与乌头相反。）
陶隐居说：槐里属于扶风郡，现在首推青州出产，吴中也有。以肉质白色者为佳，不嫌陈久，使用时都先用汤水清洗十余遍，直到滑腻感尽除，否则，会刺激咽喉。方剂中有半夏，必须配伍生姜的，也是为了制约其毒性。唐本注说：半夏，各地都有。生长在平泽中的，名叫羊眼半夏，圆白者优良，然而江南产的个头大，直径达一寸，南方人特别重视它，近来互相混用，功效状态差异很大。询问南方人，说它的苗是由跋（鸢尾），陶弘景注中说：虎掌极像半夏，注解说由跋是说鸢尾，在此注解中似乎说由跋，三件事混淆，陶弘景最终未能识别。臣禹锡等谨按蜀本草说：熟半夏可以下痰。又《图经》说：苗一茎，茎端三叶，有两根重叠，上小下大，五月采则虚小，八月采实大。采集时应当用灰埋两天，汤洗后晒干。药性论说：半夏，使药忌羊血、海藻、饴糖，柴胡为其引经药，有大毒。汤淋十遍去尽涎沫，其毒性以生姜等分制约使用。能消痰涎，开胃健脾，止呕吐，去除胸中痰满，降肺气，主治咳结。新产生的半夏，磨涂痈肿不消，能除瘤瘿气。虚而有痰气的，加用之。日华子说：味酸、辛。治疗吐食反胃，霍乱转筋，肠腹冷痰疟疾。
图经说：半夏，生于槐里川谷，现在到处都有，以齐州出产的为佳。二月生苗一茎，茎端出三叶，浅绿色，颇似竹叶而光亮，江南的似芍药叶。根下相重生，上大下小，皮黄肉白。五月、八月内采根，用灰埋两天，汤洗后晒干。一说五月采的虚小，八月采的实大。然而以圆白、陈久的为佳。那些生长在平泽的很小，名叫羊眼半夏。另外由跋极像半夏，而苗高一尺多，根如鸡蛋大，多生在林下，有人说就是虎掌的小者，足以造成混淆。半夏主治胃冷呕哕，是方药中最紧要的。张仲景治疗反胃呕吐，大半夏汤：半夏三升，人参三两，白蜜一升，用水一斗二升混合，扬一百二十遍，煮取三升半，温服一升，每日两次。也治疗膈间支饮。又主治呕哕，谷物不能下行，眩晕心悸。半夏加茯苓汤：半夏一升，生姜半斤，茯苓三两，切碎，用水七升，煎取一升半，分次温服。又主治心下悸动。半夏麻黄丸：两物等分，筛末蜜丸，大小如小豆。每服三丸，每日三次。其余主治寒厥赤丸，四逆呕吐。附子粳米汤乃是伤寒方：用半夏一升，洗去滑腻，焙干，捣末，小麦面一升，合和，用水揉成团，水煮令面熟则药成。初吞四、五枚，每日两次，逐渐增至十五枚，边煮边服，觉得病减，想再合服也很好。禁食饴糖与羊肉。
雷公说：凡是使用，不要误用白旁子的种子，真像半夏，只是咬着微酸，不入药用。如果修事半夏四两，捣了白芥子末二两，头醋六两，两味搅令浑浊，将半夏投入其中，洗三遍使用。半夏上有隙涎，如果洗不净，令人气逆，肝气怒满。圣惠方：治疗时气，呕吐逆气不下食。用半夏半两，汤浸洗七遍去滑，生姜一两同锉碎，用水一大盏，煎至六分去滓。分两次服，不计时候温服。又一方：治疗蝎子咬伤，五个孔皆相通。半夏一分为末，用水调敷。经验后方：正胃。半夏二两，天南星二两，上为末，用水五升，入坛子内，与药搅匀，浸一宿，去清水，焙干，重碾令细。每服水二盏，药末二钱，姜三片同煎至八分，温服，至五服效。斗门方：治疗胸膈壅滞，去痰开胃。用半夏净洗焙干，捣罗为末，以生姜自然汁和为饼子，用湿纸裹，于慢火中煨令香熟。水两盏，用饼子一块如弹丸大，入盐半钱，煎取一盏，温服。能去胸膈壅逆，大压痰毒及治酒食所伤，其功极验。简要济众：治疗久积冷，不下食，呕吐不止，冷在胃中。半夏五两，洗过为末，每服二钱，白面一两，以水和搜，切作棋子，水煮面熟为度。用生姜、醋调和服之。古今录验治疗喉痹。半夏末方寸匕，鸡蛋一枚头开窍子，去内黄白，盛淳苦酒令小满，纳半夏末着中，搅和鸡蛋内，以环子坐之，于炭上煎，药成置杯中，稍暖咽之。钱相公箧中方治疗蝎螫人，取半夏以水研涂之立止。深师方：治疗伤寒病汗不止。半夏熟洗干末之，生姜汤服一钱匕。子母秘录：治疗小儿腹胀。半夏少许洗，捣末，酒和丸如粟米大。每服二丸，生姜汤吞下。不愈，加之，每日两次服。又若以火炮之为末，贴脐亦佳。又一方：治疗五绝。一曰自缢，二曰墙壁压，三曰溺水，四曰魇魅，五曰产乳。凡五绝，皆以半夏一两，捣筛为末，丸如大豆，纳鼻中愈。心温者，一日可治。产书：治疗产后运绝。半夏一两，捣为末，冷水和丸如大豆，纳鼻孔中即愈。此是扁鹊法。

衍义说：半夏，今人只知道去痰，不说益脾，大概是因为能分水的原因。脾恶湿，湿则濡而困，困则不能制水。《经》说：湿胜则泻。一男子夜数如厕，有人教以生姜一两碎之，半夏汤洗，与大枣各三十枚，水一升，瓷瓶中，慢火烧为熟水，时时呷，数日便已。
Banxia (Pinelliae Rhizoma)
Pungent, neutral in nature; raw is slightly cold, cooked is warm, and it is toxic. It mainly treats chills and fever caused by Shanghan (Cold Damage), hardness below the heart, descends rebellious Qi, relieves swelling and pain of the throat and pharynx, dizziness, chest distension with cough and rebellious Qi, abdominal borborygmus, stops sweating, eliminates phlegm-heat accumulation in the heart, abdomen, chest, and diaphragm, treats cough with rebellious Qi, acute pain and hard palpable masses below the heart, vomiting and rebellious Qi due to seasonal epidemics, dissipates carbuncles and swellings, induces abortion, treats sallow complexion, and enhances facial luster. Raw Banxia causes vomiting, while cooked Banxia promotes bowel movement. When used, it must be washed with hot water until the slippery sensation is completely removed. Also known as Shoutian, Diwen, Shuiyu, and Shigu. Grows in the valleys of Huaili. The roots are harvested in May and August and dried in the sun. (Shegan (Belamcandae Rhizoma) serves as its guiding herb; it is incompatible with Zaojia (Gleditsiae Fructus Spina); it fears Xionghuang (Realgar), Shengjiang (Zingiberis Rhizoma Recens), Ganjiang (Zingiberis Rhizoma), Qinpi (Ailanthi Cortex), and Guijia (Testudinis et Chelonis Carapax et Plastrum); it is chemically opposite to Wutou (Aconiti Lateralis Radix Preparata).)
Tao Hongjing stated: Huaili belongs to Fufeng Commandery. Currently, the best quality comes from Qingzhou, though Wuzhong also produces it. Those with white flesh are superior. It does not spoil with age. Before use, it must be washed with hot water more than ten times until the slippery sensation is gone; otherwise, it will irritate the throat. In prescriptions containing Banxia, Shengjiang (Zingiberis Rhizoma Recens) must be included to counteract its toxicity. Tang Ben Zhu noted: Banxia is found everywhere. Those growing in flat marshes are called Yangyan Banxia (Sheep's Eye Pinellia), and those that are round and white are considered excellent. However, those from Jiangnan are large, up to one cun in diameter, and highly valued by Southerners. Recently, they have been used interchangeably, but their efficacy differs significantly. Inquiry with Southerners revealed that its sprout is Youba (Iris tectorum). Tao's annotation states: Huzhang (Arisaema cum Baccis) resembles Banxia closely. The annotation mentions Youba refers to Iris tectorum, yet in this note, it seems to refer to Youba, causing confusion among the three items, which Tao Hongjing ultimately failed to distinguish. Ministers Yuxi and others carefully followed the Shu Ben Cao stating: Cooked Banxia can resolve phlegm. Tu Jing stated: The sprout has a single stem with three leaves at the tip, and two overlapping roots, smaller at the top and larger at the bottom. Harvested in May, they are hollow and small; harvested in August, they are solid and large. Upon harvesting, they should be buried in ash for two days, washed with hot water, and dried. Yao Xing Lun stated: For Banxia, avoid Yangxue (Ovis Blood), Haizao (Sargassum), and Yitang (Maltose); Chaihu (Bupleuri Radix) serves as its guiding herb. It has great toxicity. It should be rinsed with hot water ten times to remove all saliva/phlegm. Its toxicity is controlled by using equal parts of Shengjiang (Zingiberis Rhizoma Recens). It can eliminate phlegm and saliva, open the stomach and strengthen the spleen, stop vomiting, remove fullness of phlegm in the chest, descend Lung Qi, and treat cough with congestion. Fresh Banxia, when ground and applied externally, can resolve persistent carbuncles and remove tumors and goiter qi. It is added for deficiency with phlegm-q stagnation. Ri Hua Zi stated: Sour and pungent. It treats vomiting and food regurgitation, cholera with muscle cramps, intestinal and abdominal cold-phlegm malaria.
Tu Jing stated: Banxia grows in the valleys of Huaili and is now found everywhere, with the best quality coming from Qizhou. In February, a single stem emerges with three leaves at the tip, light green, resembling bamboo leaves but glossy; those in Jiangnan resemble Peony leaves. The roots grow overlapping below, larger at the top and smaller at the bottom, with yellow skin and white flesh. Roots are harvested in May or August, buried in ash for two days, washed with hot water, and dried. One theory says May-harvested ones are hollow and small, while August-harvested ones are solid and large. However, round, white, and aged ones are best. Those growing in marshes are very small and named Yangyan Banxia (Sheep's Eye Pinellia). Additionally, Youba (Iris tectorum) strongly resembles Banxia, but its sprout is nearly one to two chi tall, and the root is egg-sized, often growing under forests. Some say it is a small form of Huzhang (Arisaema cum Baccis), which can cause confusion. Banxia mainly treats cold-stomach vomiting and hiccups, being one of the most essential herbs in formulas. Zhang Zhongjing treated food regurgitation and vomiting with Dabanxia Tang (Major Pinellia Decoction): Banxia (Pinelliae Rhizoma) 3 sheng, Renshen (Ginseng Radix et Rhizoma) 3 liang, White Honey 1 sheng. Mix with 12 sheng of water, stir vigorously 120 times, decoct to obtain 3.5 sheng. Take 1 sheng warm, twice daily. It also treats fluid retention between the diaphragm. It further treats vomiting and hiccups where grain cannot pass down, dizziness, and palpitations. Banxia Jia Fuling Tang (Pinellia Decoction with Poria) consists of: Banxia (Pinelliae Rhizoma) 1 sheng, Shengjiang (Zingiberis Rhizoma Recens) half a jin, Fuling (Poria) 3 liang. Cut into pieces, decoct with 7 sheng of water to obtain 1.5 sheng. Divide into warm doses. It also treats palpitations below the heart. Banxia Mahuang Wan (Pinellia and Ephedra Pill) uses equal parts of the two herbs, sifted into powder, formed into honey pills the size of small beans. Take 3 pills per dose, three times daily. Other formulas include Hanjue Chi Wan (Cold Reversal Red Pill) for cold reversal, and Sini Tang (Four Reversals Decoction) for vomiting. Fuzi Jingmi Tang (Aconite and Coix Seed Decoction) is a Shanghan formula: Use Banxia (Pinelliae Rhizoma) 1 sheng, wash to remove slipperiness, dry and roast, grind to powder. Mix with Wheat Flour 1 sheng, knead with water until cooked, form into pills the size of quail eggs. Boil in water until the flour is cooked, then the medicine is ready. Swallow 4-5 pills initially, twice daily, gradually increasing to 15 pills. Cook and take immediately. If symptoms subside, continuing the dosage is beneficial. Avoid eating maltose and mutton.
Lei Gong stated: When using, do not mistakenly use the seeds of Bai Pangzi, which look like Banxia but taste slightly sour when chewed, and are not used medicinally. If processing 4 liang of Banxia, mix with 2 liang of ground Baijiezi (Brassicae Semen) and 6 liang of first vinegar. Stir until turbid, immerse the Banxia, wash three times, and use. Banxia contains interstitial saliva; if not washed clean, it causes rebellious Qi and liver qi stagnation with anger. Shenghui Fang treated epidemic fevers with vomiting and inability to eat: Use Banxia (Pinelliae Rhizoma) half a liang, soak in hot water and wash seven times to remove slipperiness. Mix with 1 liang of chopped Shengjiang (Zingiberis Rhizoma Recens). Decoct with one large bowl of water until reduced to 60%. Strain. Divide into two doses, take warm at any time. Another prescription treated scorpion stings where five holes were connected: Grind Banxia (Pinelliae Rhizoma) one fen into powder, mix with water, and apply. Jingyan Houfang regulated the stomach: Banxia (Pinelliae Rhizoma) 2 liang, Tian Nanxing (Arisaematis Rhizoma) 2 liang. Grind into powder. Place in a jar with 5 sheng of water, stir well, soak overnight, discard clear water, dry and roast, grind finely. Take 2 qian of powder with 2 bowls of water and 3 slices of ginger, decoct to 80%, take warm. Effective after five doses. Doumen Fang treated chest and diaphragm stagnation, resolving phlegm and opening the stomach: Wash and dry clean Banxia (Pinelliae Rhizoma), grind into powder. Mix with fresh juice of Shengjiang (Zingiberis Rhizoma Recens) to form cakes. Wrap in wet paper, bake slowly over low heat until fragrant and cooked. Add one cake (size of a quail egg) to 2 bowls of water with half a qian of salt, decoct to 1 bowl, take warm. It removes chest-diaphragm rebellious Qi, suppresses phlegm toxins, and treats damage from alcohol and food, with verified efficacy. Jianyao Zhizhong treated long-standing cold accumulation, inability to eat, incessant vomiting, and cold in the stomach: Banxia (Pinelliae Rhizoma) 5 liang, washed and powdered. Take 2 qian per dose. Mix with 1 liang of white flour, knead with water, cut into chess-piece shapes, boil until flour is cooked. Take mixed with Shengjiang (Zingiberis Rhizoma Recens) and vinegar. Gujin Luyan treated throat obstruction (Houbi): Take Banxia powder one square inch scoop. Open an egg at the head, remove yolk and white, fill with pure vinegar, add Banxia powder, stir inside the eggshell. Sit the shell on a ring over charcoal, cook until done. Place in a cup, swallow when slightly warm. Qian Xiang Gong's Box Formula treated scorpion stings: Grind Banxia (Pinelliae Rhizoma) with water and apply; relief is immediate. Shenshi Fang treated continuous sweating in Shanghan disease: Wash cooked Banxia (Pinelliae Rhizoma), dry, powder, and take one qian-bi with Shengjiang (Zingiberis Rhizoma Recens) tea. Zimu Milu treated pediatric abdominal distension: Wash a small amount of Banxia (Pinelliae Rhizoma), powder, mix with wine to form pills the size of millet grains. Take 2 pills swallowed with Shengjiang (Zingiberis Rhizoma Recens) tea. If not cured, increase dosage, twice daily. Alternatively, roast over fire, powder, and apply to the umbilicus. Another prescription treated "Five Extinctions" (sudden death-like states): 1. Hanging, 2. Crushed by walls, 3. Drowning, 4. Nightmares/demonic possession, 5. Childbirth complications. For all five, use 1 liang of Banxia (Pinelliae Rhizoma), powder, form pills the size of soybeans, insert into the nose. If the heart is still warm, it can be treated within one day. Chanshu treated postpartum fainting: 1 liang of Banxia (Pinelliae Rhizoma), powder, mix with cold water to form soybean-sized pills, insert into nostrils for immediate recovery. This is the method of Bian Que.
Yuyao Yuan treated diaphragmatic stagnation and wind-phlegm: Banxia (Pinelliae Rhizoma) as needed. Soak in sour bean water overnight, wash 5-7 times with warm water to remove bad odor, dry in the sun, powder. Knead with rice water to form cakes, dry in the sun, powder again. For every 5 liang, add 1 qian of Sheng Naozi (Borneolum Syntheticum), grind uniformly. Form chicken-head-sized pills with thick rice water. Store in gauze bags, dry in shade in a ventilated place. Take one pill with good tea or Mint Tea. Ziling Yuanjun Nanyue Furen Neizhuan treated sudden death: Blow Banxia powder (soybean-sized) into the nose.
Yanyi stated: People today only know Banxia (Pinelliae Rhizoma) resolves phlegm, not that it benefits the spleen, likely because it separates fluids. The Spleen dislikes dampness; dampness makes it soggy and sluggish, preventing it from controlling fluids. The Classic states: Excess dampness leads to diarrhea. A man suffered frequent nocturia. Someone advised crushing 1 liang of Shengjiang (Zingiberis Rhizoma Recens), washing Banxia (Pinelliae Rhizoma) with hot water, mixing with 30 dates, boiling in 1 sheng of water in a porcelain bottle over slow fire to make a tea. Sip occasionally. Cured in a few days.
