通中发汗，头疼风湿总蠲除。利便开关，香港脚奔豚通解散。专攻喉痹，亦可安胎。伤寒
寒热
皆宜，面目浮肿亦治。
葱味最辛，肺之药也。故解散之用居多。

凡中风、中暑、中气、中毒、中恶、霍乱等一切卒暴之证，用姜汁和童便服之。姜汁能

轻可去实，为发散第一药。惟在冬月，真有寒邪在表者，宜之。或非冬月，或无寒邪，
或寒
邪在里，或伤风等证，虽发热恶寒，不头痛身疼而拘急，六脉不浮紧者，皆不可用。虽可汗
之证，亦不宜多服，汗为心液，若不可汗而汗，与可汗而过汗，则心血为之动矣。或亡阳，
或血溢，而成大患，可不慎哉。
麻黄乃太阳经药，兼入肺经。肺主皮毛；葛根乃阳明经药，兼入脾经。脾主肌肉，发散
虽同
，所入迥异。
【葱白】
味道辛，性质平。归入肺、胃两经。忌与枣、蜜、狗肉、野鸡肉同食。
能通达中焦并发汗，头痛及风湿之症皆可清除。通利小便并开通关窍，脚气病（香港脚）及奔豚气（一种自觉有气从少腹上冲胸咽的病证）皆可解散。专治喉痹（咽喉肿痛闭塞），也能安胎。伤寒引起的寒热往来皆适宜，面目浮肿也能治疗。
葱的味道最辛，是入肺的药。所以发散解表的作用居多。
多吃葱，会让人神志昏沉、头发脱落、虚气上冲。
【生姜】
味道辛，性质热，无毒。归入肺、胃两经。
生用能发表散邪，熟用可温中暖胃。开胃有奇效。止呕是极好的药剂。气胀腹痛都妙，痰凝血滞也都良善。刮去姜皮，对于胀满病症必定要用。
凡是中风、中暑、中气、中毒、中恶、霍乱等一切突然暴发的病证，用姜汁配合童子尿服用。姜汁能化痰开窍，童子尿能降火。古方用姜茶治疗痢疾，热痢保留姜皮，冷痢去掉姜皮，非常巧妙。忌与干姜同服。
【桂枝】
味道辛、甘，性质温。归入心、肺、膀胱三经。
助阳散寒，温通经脉。通达营卫，调和表里。无汗时能发汗，有汗时能止汗。调理心腹疼痛。搜剔关节痹痛。
直行兼作奔豚气的向导。
《本经疏证》说：“和营、通阳、利水、下气、行瘀、补中是桂枝的六大功效。”
【麻黄】
味道苦，性质温，无毒。归入心、肺、膀胱、大肠四经。浓朴为使药。畏辛夷、石苇。去掉根节，用水煮，去掉浮沫。
去除营分中的寒气，宣泄卫分的风邪。发汗依靠它的温散作用，消肿在于它行水的功能。既主治实喘，也配伍用于痛痹。
轻清之品可以去实邪，是发散的第一要药。只有在冬季，确实有寒邪在体表时，才适宜使用。如果不是冬季，或者没有寒邪，或者寒邪在体内，或者伤风等病证，虽然发热恶寒，但不头痛身疼且拘急，六脉不浮紧的，都不可用。即使是可汗之证，也不宜多服。汗为心之液，如果不可汗而强发其汗，或可汗而过汗，就会扰动心血。或者导致亡阳，或者导致血溢，从而造成大患，能不谨慎吗？
麻黄是太阳经的药物，兼入肺经。肺主皮毛；葛根是阳明经的药物，兼入脾经。脾主肌肉，发散作用虽然相同，但所入经络迥然不同。
[Scallion White]
Pungent in flavor, neutral in nature. Enters the Lung and Stomach meridians. Contraindicated with dates, honey, dog meat, and pheasant meat.
It unblocks the middle jiao and induces sweating; it eliminates headache and rheumatism. It promotes urination and opens orifices; it resolves Hong Kong foot (podagra/foot swelling) and Ben Tun Qi (a condition characterized by gas rushing from the lower abdomen to the chest/throat). It specifically treats Hou Bi (sore throat with obstruction), and can also calm the fetus. It is suitable for chills and fever caused by Shang Han (Cold Damage), and treats edema of the face and eyes.
The flavor of scallion is most pungent, and it is a herb for the Lung. Therefore, its use in dissolving and releasing is predominant.
Excessive consumption of scallion causes mental confusion, hair loss, and upward rushing of deficient qi.
[Fresh Ginger]
Pungent in flavor, hot in nature, non-toxic. Enters the Lung and Stomach meridians.
Raw ginger releases the exterior, while cooked ginger warms the middle jiao. It has miraculous effects on opening the appetite. It is a supreme remedy for stopping vomiting. It is excellent for abdominal distension and pain, and beneficial for phlegm coagulation and blood stasis. Scraping off the ginger peel is essential for treating distension.
For all sudden acute conditions such as Zhong Feng (Wind Stroke), Zhong Shu (Heat Stroke), Zhong Qi (Qi Collapse), Zhong Du (Poisoning), Zhong E (Evil Qi Invasion), and Huo Luan (Cholera-like disorder), administer ginger juice mixed with child's urine. Ginger juice can resolve phlegm and open orifices, while child's urine can descend fire. Ancient formulas use ginger tea to treat dysentery: retain the peel for heat dysentery, remove the peel for cold dysentery, which is highly effective. Contraindicated with dried ginger.
[Cinnamon Twig]
Pungent and sweet in flavor, warm in nature. Enters the Heart, Lung, and Bladder meridians.
It assists yang and disperses cold, warms meridians and unblocks collaterals. It reaches Ying (Nutritive) and Wei (Defensive) levels, and harmonizes interior and exterior. It induces sweating when there is no sweat, and stops sweating when there is sweat. It regulates pain in the heart and abdomen. It searches out bi-syndrome (painful obstruction) in joints.
It acts directly and serves as a guide for Ben Tun Qi.
*Ben Jing Shu Zheng* states: "Harmonizing Ying, unblocking Yang, promoting diuresis, directing qi downward, moving blood stasis, and tonifying the middle are the six major efficacies of Guizhi."
[Ephedra Stem]
Bitter in flavor, warm in nature, non-toxic. Enters the Heart, Lung, Bladder, and Large Intestine meridians. Peucedani Radix (Qianhu) or Magnoliae Officinalis Cortex (Houpo) may be used as an envoy. It is incompatible with Xinyi (Magnolia Flower) and Shiwei (Pyrrosiae Folium). Remove root nodes, boil in water, and skim off the foam.
It removes cold qi from the Ying level and vents wind pathogens from the Wei level. Its sweating effect relies on its warm dispersion; its消肿 (reducing swelling) lies in its ability to move fluids. It is indicated for excess asthma and is combined in treatment for painful bi-syndrome.
Light substances can dispel excess; it is the primary herb for dispersion. It is suitable only in winter when there is truly a cold pathogen at the exterior. If not in winter, or if there is no cold pathogen, or if the cold pathogen is in the interior, or in cases of wind-cold injury where there is fever and aversion to cold but no headache, body ache, or stiffness, and the six pulses are not floating and tight, it must not be used. Even in conditions where sweating is indicated, it should not be taken excessively. Sweat is the fluid of the Heart; forcing sweat when inappropriate, or sweating excessively when appropriate, will disturb Heart Blood. This may lead to Yang collapse or hemorrhage, causing severe complications. Can one not be cautious?
Mahuang is a herb of the Taiyang (Greater Yang) meridian, and additionally enters the Lung meridian. The Lung governs skin and hair; Gegen (Kudzu Root) is a herb of the Yangming (Bright Yang) meridian, and additionally enters the Spleen meridian. The Spleen governs muscles. Although their dispersing actions are similar, the meridians they enter are vastly different.
