【主治】
解暑热，利小便。又治水湿病非常有效。肺得到它则清化功能运行。但是饮食不节制、劳累辛苦的人，如果患伤暑，导致大热大渴，汗出如雨，烦躁喘促，或者腹泻或者呕吐，必须补益元气以降火，不可一概使用葱白来加重体表的虚弱。只有夏季乘凉饮冷，导致阳气被阴邪所遏制，出现头痛发热恶寒，烦躁口渴，或者呕吐或者腹泻，或者霍乱的，适宜用葱白来发越阳气，散水和脾。俗人用它代替茶汤饮用，说能解暑，这是很大的错误。另外它的性质温，不可热饮，反而会导致呕吐逆气。
【气味】
味辛，性平。叶性温，根须性平，都无毒。药性上升，属阳。归手太阴肺经和足阳明胃经。
【主治】
发散以通达上下阳气。所以《活人书》治疗伤寒头痛剧烈如破，用连须葱白汤为主方。张仲景治疗少阴病下利清谷，里寒外热，四肢厥逆脉微弱的，用白通汤为主方。方内用葱白。如果面色赤红的，用四逆汤加葱白。腹部疼痛的，去掉葱白。总原则是肾厌恶燥，急需食用辛味食物来润之。葱白的辛温，用来通达阳气。另外将葱管吹盐入尿道内，治疗小便不通及转脬（尿潴留）危急病症。但白色主冷，青色主热，伤寒汤剂中不得用青葱。另外春季吃生葱，让人脸上起游风（荨麻疹类皮肤病）。生葱同蜂蜜吃导致腹泻。烧葱同蜂蜜吃壅滞气机杀人。生葱合枣吃让人生病。合犬肉、雉肉同吃，让人患血病。
[Flavor and Nature]
Pungent, neutral in nature, non-toxic.
[Indications]
Evil qi within the five zang organs. Expels Taenia solium (pork tapeworm). Disperses wheezing in the intestines. Primarily treats accumulated cold qi. Heart and abdominal fixed masses and pain. Treats wind-deficiency syndrome of the uterus in women.
Pediatric malnutrition diarrhea and cold dysentery.
[Flavor and Nature]
Pungent, slightly warm, non-toxic. Capable of ascending and descending, belongs to Yang. Enters the Hand-Taiyin Lung Meridian and Foot-Taiyin Spleen Meridian.
[Indications]
Wind-water toxic swelling. Removes evil qi. Stops cholera-like vomiting and diarrhea. Stomach and spleen vomiting and regurgitation. Warms the middle jiao and promotes free flow of qi. Upper jiao stagnation heat. Bad breath after drinking alcohol. All are treated by decocting with scallion water.
[Flavor and Nature]
Pungent, slightly warm, non-toxic. Belongs to Metal and Water. Possesses the efficacy of penetrating from top to bottom.
[Indications]
Resolves summerheat and promotes urination. Also very effective for treating water retention. When the Lung receives it, its clearing and transforming functions operate. However, for those who do not regulate their diet or engage in hard labor, if they suffer from summerheat injury leading to high fever, extreme thirst, profuse sweating like rain, restlessness, panting, or diarrhea/vomiting, one must tonify primordial qi to descend fire; one should not indiscriminately use scallions as this would further deplete the exterior. Only when cooling off in summer and consuming cold drinks causes yang qi to be suppressed by yin pathogens, resulting in headache, fever, aversion to cold, restlessness, thirst, vomiting, diarrhea, or cholera, is it appropriate to use scallions to vent yang qi, disperse water, and harmonize the spleen. Laypeople use it as a substitute for tea, claiming it resolves summerheat; this is a serious error. Furthermore, its nature is warm and should not be drunk hot, as this may cause vomiting and regurgitation.
[Flavor and Nature]
Pungent, neutral in nature. Leaves are warm, roots and bulbs are neutral; all are non-toxic. Ascending and Yang. Enters the Hand-Taiyin Lung Meridian and Foot-Yangming Stomach Meridian.
[Indications]
Disperses to unblock yang qi throughout the upper and lower body. Therefore, *Huoren Shu* (Book of Life) treats severe headache due to Cold Damage using Decoction of Scallion Bulb with Roots as the main formula. Zhang Zhongjing treats Shaoyin disease with clear grain diarrhea, interior cold with exterior heat, cold limbs, and faint pulse, using Bai Tong Tang (White Connecting Decoction) as the main formula, which contains scallion bulb inside. If the complexion is red, Si Ni Tang (Frigid Extremities Decoction) is used with added scallion bulb. If there is abdominal pain, remove the scallion bulb. The general principle is that the Kidney dislikes dryness, so pungent foods should be eaten urgently to moisten it. The pungent-warm nature of scallion bulb is used to unblock yang qi. Additionally, blowing salt into the urethra via a scallion tube treats urinary retention and critical conditions like bladder torsion. However, white indicates cold and green indicates heat; green scallions must not be used in Cold Damage decoctions. Eating raw scallions in spring causes migratory wind (urticaria) on the face. Eating raw scallions with honey causes diarrhea. Eating roasted scallions with honey obstructs qi and can be fatal. Eating raw scallions with dates causes illness. Eating scallions with dog meat or pheasant meat causes blood diseases.
