葱，味辛，气温，升也，阳也，无毒。入足阳明胃经，及手太阴肺脉。疏通关节，
祛逐风邪，理霍乱转筋，治伤寒头痛，杀鱼肉之毒，通大小肠，散面目肿浮，止心腹
急
痛，去喉痹，愈金疮折伤血出疼，捣烂炒热，傅之血止。安娠妊，塞衄血，除香港脚奔豚之邪
，疗蛇伤蚯蚓之毒，功专发散，食多神昏。病属气虚，尤勿沾口。可为佐使，而亦可为君臣
。大约为佐使者内治也，为君臣者外治也。外治宜多，内治宜少也。
葱有益而亦有损。益者，通气而散邪。损者，昏目而神夺也。北人喜食葱，往往坏目，
习俗
使然，不能禁耳。
葱善通脉，仲景夫子所以制通脉汤也。盖葱空中而善通气，通气即通脉也。温其里之寒，
解
其表之热，故脉之不通者即通。世人疑用葱以散邪，则失用葱之意矣。
韭，味辛微散，气温性急。温中下气，归心益阳，暖膝胫，和脏腑，除胸腹 癖痼冷，
止茎
管白浊遗精，活血解毒。少用则有益于肾，多食则有损于心，蜜食杀人，不可不戒。
韭子善止遗精，功胜于叶，然亦不可多用也。
或问《神农本草》云病患可久服韭，而吾子曰不可多食，岂神农非欤？嗟乎。《神农本
草》
因传世既久，远落误传耳。夫韭性辛温，尤善通利。虽曰益肾，未免消多于补，多食能令人
神昏，正伤心之明验。此予所以戒之也。
葱，味道辛，性质温，具有上升的特性，属于阳，没有毒性。进入足阳明胃经，以及手太阴肺脉。能够疏通关节，祛除风邪，调理霍乱引起的转筋（肌肉痉挛），治疗伤寒导致的头痛，消除鱼肉产生的毒素，通畅大小肠，消散面目浮肿，停止心腹部的急痛，去除喉痹（咽喉肿痛闭塞），治愈金疮折伤出血疼痛，捣烂后炒热敷用可止血。安胎，止鼻衄血（鼻出血），消除香港脚（脚气病）和奔豚（一种自觉有气从少腹上冲胸咽的病症）的病邪，治疗蛇咬伤和蚯蚓毒，功效专门在于发散，食用过多会导致神志昏沉。病情属于气虚的人，尤其不要接触食用。可以作为佐使药，也可以作为君臣药。大致来说，作为佐使药是用于内治，作为君臣药是用于外治。外治应该多用，内治应该少用。
葱有益处也有损害。益处在于，通气并疏散邪气。损害在于，损伤视力并耗夺精神。北方人喜欢食用葱，往往导致眼睛受损，这是习俗造成的，无法禁止。
葱善于通脉，张仲景先生因此制定了通脉汤。因为葱中间空心而善于通气，通气也就是通脉。温暖内部的寒邪，解除体表的发热，所以脉搏不通畅的情况就能得到疏通。世人怀疑使用葱来疏散邪气，那就误解了使用葱的本意了。
韭菜，味道辛微散，性质温且性急。温暖中焦，降逆下气，归入心脏并补益阳气，温暖膝盖和小腿，调和脏腑，消除胸腹部的癖积和顽固冷痛，停止尿道白浊和遗精，活血解毒。少量使用对肾脏有益，大量食用则损害心脏，用蜂蜜拌食会致死，不可不警惕。
有人问：《神农本草经》说病人可以长期服用韭菜，而您却说不可多吃，难道神农氏错了吗？唉，《神农本草经》因为流传年代久远，远道而来出现了误传罢了。韭菜性质辛温，尤其善于通利。虽然说是补肾，未免消耗多于补益，多吃能让人神志昏沉，这正是伤心害神的明显证据。这就是我告诫大家的原因。
Scallion (Cong), with a pungent flavor and warm temperature, possesses ascending properties and belongs to Yang; it is non-toxic. It enters the Foot-Yangming Stomach Meridian and the Hand-Taiyin Lung Channel. It unblocks joints, expels Wind pathogenic factors, regulates convulsions associated with Huoluan (Cholera-like syndrome with muscle spasms), treats headaches caused by Shanghan (Cold Damage), neutralizes toxins from fish and meat, promotes the free flow of the Large and Small Intestines, dissipates edema of the face and eyes, stops acute pain in the heart and abdomen, removes Houbi (sore throat with obstruction), heals bleeding and pain from metallic wounds and fractures, and when mashed, heated, and applied externally, it stops bleeding. It calms pregnancy, stops Nosebleed (Nu Xue), eliminates pathogens of Hongxiangjiao (Beriberi) and Bentun (a condition characterized by gas rising from the lower abdomen to the chest and throat), and treats snakebites and earthworm toxicity. Its function is specialized in dispersing and diffusing; excessive consumption leads to mental confusion. In cases of Qi deficiency, one should especially avoid consuming it. It can serve as an Assistant or Guide herb, but also as a Sovereign or Minister herb. Generally, when used as an Assistant or Guide, it is for internal treatment; when used as a Sovereign or Minister, it is for external treatment. External treatment requires larger doses, while internal treatment requires smaller doses.
Scallion has both benefits and drawbacks. The benefit lies in promoting Qi circulation and dispersing pathogenic factors. The drawback is that it impairs vision and depletes Shen (Spirit). People in the North enjoy eating scallion, often damaging their eyesight; this is due to custom and cannot be strictly prohibited.
Scallion excels at unblocking vessels (Mai); therefore, Master Zhang Zhongjing formulated Tongmai Tang (Pulse-Unblocking Decoction). Since scallion is hollow inside, it excels at promoting Qi circulation; promoting Qi circulation is equivalent to unblocking vessels. It warms internal Cold and resolves exterior Heat, thus unblocking obstructed pulses. Those who doubt the use of scallion for dispersing pathogens misunderstand its intended purpose.
Chinese Chive (Jiu), with a pungent and slightly dispersing flavor, has a warm and urgent nature. It warms the Middle Jiao, directs rebellious Qi downward, enters the Heart, tonifies Yang, warms the knees and shins, harmonizes the Zang-Fu organs, eliminates fixed masses and stubborn cold in the chest and abdomen, stops white turbidity in the urethra and spermatorrhea, invigorates Blood, and detoxifies. Used in small amounts, it benefits the Kidney; used in large amounts, it damages the Heart. Consuming it with honey can be fatal; caution is essential.
The seed of Chinese chive (Jiu Zi) excels at stopping spermatorrhea and is more effective than the leaves, yet it should not be used in excessive amounts.
One might ask: "Shennong's Classic of Materia Medica states that patients can consume chives for a long time, yet you say they should not be eaten in excess. Is Shennong incorrect?" Alas! Due to the long history of transmission, errors have arisen in Shennong's Classic of Materia Medica. The nature of chive is pungent and warm, excelling in promoting free flow and urination. Although it is said to benefit the Kidney, it tends to drain more than it tonifies. Excessive consumption causes mental confusion, which is clear evidence of its damaging effect on the Heart. This is why I issue this warning.
