葱白禀受天的阳气，获得地的金味，中间空心象征肺脏，味道辛平，所谓“平”即指凉性，且性质无毒。葱分为寒热两类，葱白性冷，葱青色热，所以在治疗伤寒的汤剂中，不使用葱青。它入入手太阴肺经、足厥阴肝经和足阳明胃经，因为辛味能够发散解肌，能够通达上下的阳气，所以凡是外来的拂郁（气机郁滞）诸症，皆由其主治，具有辛凉、辛润、利窍、解散通气的作用。
葱白入肺经和胃经。能发汗疏通骨节，治疗伤寒引起的头痛，通利大小肠，消散面目浮肿，缓解心腹急痛，去除喉痹（咽喉肿痛闭塞），安胎，如治疗香港脚气病，需连须煎服。若出现脱阳厥逆证，可将葱白炒热熨烫脐部；对于新近折断皮肤有渗出液的情况，可涂敷于患处以治疗跌打损伤和金创（金属利器造成的创伤）。不可与蜂蜜、松菜、常山同用，否则会导致死亡。葱叶入药煎汤，可洗涤疮疥及风水引起的肿痛。葱子能补不足，温中益精。葱根主治伤寒头痛。
主治（痘疹合参）：痘疹初起发热时，可用此药解肌，但夏季忌用。
按语：葱白最辛，是入肺的药物，多食令人神志昏沉、头发脱落，导致虚气上冲，这大概是其走窜利窍的缘故吧。
马齿苋，禀受天的阴寒之气，兼得地中的金气，所以其叶节间含有水银（注：古人观察到的白色汁液或矿物质沉积，非现代化学汞），这是因为得金气多的缘故。味道辛、苦，气寒，无毒。其性辛寒，所以能凉血散热。因此，它能治疗痈疮、疔肿、白秃（头皮癣类疾病）、三十六种风结疔疮，捣碎外敷则肿胀消散、疔根拔出，绞汁内服则恶物当下，二便通畅，虫热能除，目翳能退，胎孕能滑，这些都是辛寒滑利功效的体现。凡脾胃虚寒、大便滑泄者禁用。勿与鳖甲同用，否则能化小鳖伤人。治疗赤白痢疾，不问老少、孕妇，捣取汁三合，与鸡蛋清调和，微温后顿服，不过两次发作即可痊愈。治疗多年的恶疮，百方不愈，或者疼痛游走不止者，并捣碎外敷，不过两三次即可痊愈。治疗疔疮肿毒，用马齿苋二分，锻石三分，研为末，用鸡蛋清调和敷之即愈。
苋实能除邪，利大便和小便，明目退去白翳和青盲（视力障碍），杀灭疣虫，去除寒热。叶入血分，通经络，逐瘀血功效显著，下胎产最快捷，孕妇临产时，煮食易于分娩，但不要多吃，以免寒凉伤中损腹，忌与鳖同食。马齿苋，性滑，主治与苋实大致相同，在疮科尤为擅长，杖疮敷之可散血，疔疮敷之可引出疔根，痈疮痘毒结疮，均用外敷治愈，马咬伤、马汗射工毒等，也取汁涂抹痊愈。
Congbai (Scallion White) inherits the Yang Qi of Heaven and acquires the Metal flavor of Earth. Its hollow center resembles the Lung organ. It tastes Pungent and Neutral; "Neutral" here implies a Cool nature, and it is non-toxic. Scallions are categorized into Cold and Hot types: Congbai is Cold, while the green part is Hot. Therefore, in decoctions for treating Shanghan (Cold Damage), the green part is not used. It enters the Hand Taiyin Lung Meridian, Foot Jueyin Liver Meridian, and Foot Yangming Stomach Meridian. Because Pungency can disperse and release the muscle layer, and can unblock the Yang Qi of the upper and lower body, it governs all disorders caused by external obstruction and stagnation. It serves the function of being Pungent-Cool, Pungent-Moistening, opening orifices, dissipating constraint, and promoting circulation.
Congbai enters the Lung and Stomach meridians. It induces sweating to unblock joints, treats headache due to Shanghan, promotes bowel and bladder movements, disperses edema of the face and eyes, relieves acute pain in the heart and abdomen, removes Hou Bi (obstruction of the throat), calms pregnancy, and treats Hongxiangjiaoqi (Gouty Arthritis/Chronic Edema of the legs), requiring boiling with roots attached. For Tuo Yang Jue Ni syndrome (collapse of Yang with cold extremities), stir-fried Congbai is applied hot to the navel. For fresh skin abrasions with exudate, it is applied topically to treat trauma and metallic injuries. It must not be used together with Honey, Songcai (Pine vegetable), or Changshan (Radix Dichroae), otherwise it may cause death. The leaves, when decocted, can wash sores, scabies, and swelling/pain due to Wind-Water. The seeds tonify deficiencies, warm the middle, and benefit essence. The root treats headache due to Shanghan.
Indications (Integration of Smallpox and Rash): When smallpox/rash initially presents with fever, this herb releases the muscle layer; however, it is contraindicated in summer.
Commentary: Congbai is extremely pungent and acts on the Lung. Excessive consumption causes mental confusion and hair loss, leading to the upward rush of deficient Qi, likely due to its penetrating and draining properties.
Machi Xian (Portulaca Oleracea) inherits the Yin-Cold of Heaven and combines with the Metal Qi of the earth. Hence, its leaf nodes contain mercury-like substances due to abundant Metal Qi. It tastes Pungent and Bitter, has a Cold nature, and is non-toxic. Its Pungent-Cold nature allows it to cool blood and dissipate heat. Thus, it treats carbuncles, sores, furuncles, alopecia barbae/capitis (white baldness), and thirty-six types of wind-contracted furuncles. Applied topically as a paste, it reduces swelling and extracts the root of the furuncle. Taken as juice, it expels pathogenic matter, promotes urination and defecation, eliminates insect-heat, reverses corneal opacity (cataract/macular degeneration), and facilitates childbirth. These effects result from its Pungent-Cold, slippery, and draining actions. It is contraindicated in cases of Spleen-Stomach deficiency-cold and loose stools. Do not use with Biejia (Tartar Testudinis), as it may transform into a small turtle causing injury. To treat Chi Bai Xia Li (Dysentery with red and white discharge), regardless of age or pregnancy status, take 3 he of fresh juice mixed with one egg white, warm slightly, and drink at once. Recovery occurs within two doses. For chronic malignant sores unresponsive to other treatments, or those with wandering pain, apply crushed paste topically; healing occurs within two to three applications. For furuncles and toxic swellings, mix Machi Xian (2 parts) with Duanshi (Calcined Alumen, 3 parts), powder them, and apply with egg white for cure.
Xianshi (Amaranthus Seeds) dispels evil pathogens, promotes bowel and bladder movements, brightens eyes, removes white films and blindness, kills warts/insects, and resolves chills and fever. The leaves enter the Blood level, unblock meridians, and excel at expelling blood stasis. They most rapidly induce abortion. Pregnant women near delivery may boil and eat them to facilitate labor, but should not consume excessively, as coldness damages the middle and abdomen. Contraindicated with Turtle. Machi Xian is slippery in nature. Its indications are similar to Xianshi, especially in dermatology. It dissipates blood stasis in whip-mark injuries, extracts the root of furuncles, and heals carbuncles and smallpox toxins via topical application. It also cures horse bites, horse sweat poisoning, and She Gong Du (archerfish/spider venom).
Indications (Integration of Smallpox and Rash): Machi Xian treats carbuncle toxins and promotes bowel/bladder movements. It should not be taken in large amounts to avoid damaging Stomach Qi. For post-smallpox gingival ulcers, calcined Machi Xian powder should be insufflated.
