《神农本草经》记载用葱煮汤，治疗伤寒引起的寒热往来、中风、面目浮肿，能够促使发汗。
【发明】
葱茎味道辛温，药性上升，归入手太阴肺经和足阳明胃经，专门主司发散，以疏通上下阳气，这就是《神农本草经》中记载的煮汤主治功效。因此，对于伤寒引起的剧烈头痛，使用连须葱白配伍香豉组成的香豉汤。少阴病出现下利清谷（腹泻排出未消化食物）、里寒外热、四肢厥冷且脉象微弱的情况，在白通汤中使用葱白，是因为葱白辛温能通达阳气。妊娠期间感受风邪导致的喘咳，非葱白和橘皮不能消除，且葱白还能安胎顺气。金创骨折损伤导致出血疼痛不止者，用带叶的葱煨熟后敷在患处，变冷后立即更换，疼痛立刻停止，且不会留下瘢痕。这是因为葱叶专门消散血气，葱须专门通行经络，葱花主治心痹痛如刀刺般疼痛，葱子能明目，补益中气不足。蟠葱专门主治冷热疝气。胡葱能化解五石散，使桂枝化为水状，治疗肿毒。
蒜个头小的称为蒜，大的称为胡蒜。
味道辛温，有小毒。服用云母的人严禁食用，胡蒜、独颗蒜尤其禁忌。
【发明】
胡蒜与普通蒜的功效相似，都归入手太阴肺经和足阳明胃经。气味辛辣猛烈，能通达五脏，贯通各个孔窍，去除寒湿，辟除邪恶之气，消除痈肿，化解症积及肉食积滞，主治溪毒并降气。治疗蛊毒、蛇虫咬伤、沙虱疮等，这是它的功效。夏季食用可以解暑，但多食会耗伤元气、损害视力。养生之人应当禁忌。用艾火灸烤独颗蒜效果很好，因为其药力专一。凡是中暑毒的人，烂嚼三四瓣吞下即可见效。又有鼻出血不止的情况，将蒜捣碎贴敷于足心，鼻血止住后立即擦去。蒜泥水一次性服用两升，可吐出腹中的虫积。对于噎膈（吞咽困难）食物无法咽下、腹部灼热如火、手不可触碰的症状，都有疗效。但是胃虚食少的人，误服此法会加速病情恶化。香港脚风病（脚气病），以及时行病（流行性疾病）痊愈后应忌食，因为它能鼓动残留的病邪。服用云母、钟乳石的人不要食用，因为它会搅散药力，触犯必致腹痛泄泻，之前的治疗效果全部废弃。小蒜主治霍乱引起的腹中不安，温中焦，祛除邪气痹阻和毒瓦斯。《黄帝内经》说，吃小蒜、生吃鱼，会使人夺去气阴，导致阴核疼痛，不能与韭菜同食，否则会使身体沉重。
Hucong (Allium fistulosum var. bulbiferum) is of good quality; Pancong (Allium cepa var. ascalonicum, also known as Dragon Claw Scallion).
It is pungent and neutral in nature, non-toxic. It is contraindicated for those taking Dihuang Tang (Rehmannia Root Decoction), Changshan (Dichroa Root), or Miguui (Honey-processed Cinnamon Twig), as consuming it will render the medicinal efficacy ineffective. Raw Cong (Scallion/Garlic Chive) is particularly to be avoided. Consuming Cong together with chicken, pheasant, or dog meat can induce blood disorders (bleeding or abnormal blood circulation).
The *Shennong Bencao Jing* records that decocting Cong into a soup treats chills and fever associated with Shanghan (Cold Damage), wind-stroke, and edema of the face and eyes, promoting sweating.
[Invention/Commentary]
The stem of Cong has a pungent and warm flavor, ascending to enter the Hand-Taiyin Lung Meridian and Foot-Yangming Stomach Meridian. It specializes in dispersing pathogens and unblocking Yang Qi throughout the upper and lower body, which corresponds to the therapeutic indications recorded in the *Shennong Bencao Jing*. Therefore, for severe headache caused by Shanghan, Xiangchi Tang (Fermented Soybean Decoction with Scallion White) containing scallion white with roots is used. In Shaoyin disease presenting with diarrhea of undigested food, internal cold with external heat, cold limbs, and a faint pulse, Congbai (White Part of Scallion) is included in Baitong Tang (Bai Tong Decoction) because its pungent-warm nature unblocks Yang Qi. For asthma and cough due to wind pathogen during pregnancy, only Congbai and Jupi (Tangerine Peel) can eliminate the condition, and they also calm the fetus and regulate Qi. For traumatic injuries (Jinchuang) with fractures, bleeding, and unceasing pain, cooked scallions with leaves are applied topically; replacing them frequently while warm stops the pain immediately without leaving scars. This is because Congye (Scallion Leaves) specifically dissipates blood and Qi, Congxu (Scallion Roots) specifically promotes meridian circulation, Conghua (Scallion Flowers) treats heart bi syndrome with stabbing pain like a knife, and Congzi (Scallion Seeds) brightens the eyes and supplements insufficient Middle Qi. Pancong specifically treats cold and hot hernia. Hucong (Large Green Onion) resolves the "Five Minerals" (Wushi San), dissolves Guizhi (Cinnamon Twig) into water, and treats carbuncles and toxic swellings.
Garlic bulbs that are small are called Suan (Garlic); large ones are called Husuan (Wild Garlic/Large Garlic).
They are pungent and warm in nature, with slight toxicity. They are strictly forbidden for those taking Yunmu (Mica). Husuan and Dukesuan (Single-clove Garlic) are especially contraindicated.
[Invention/Commentary]
Husuan and ordinary Suan have similar functions, entering both the Hand-Taiyin Lung Meridian and Foot-Yangming Stomach Meridian. Their aroma is pungent and fierce; they can penetrate the Five Zang Organs, reach all orifices, dispel cold-dampness, ward off evil qi, resolve carbuncles and swellings, transform accumulations (Zhengji) and meat stagnation, treat "stream poison" (toxicity from mountain streams), and direct Qi downward. They are effective for treating gu poison (parasitic diseases), snake and insect bites, and shashi sores (sandfly/mite dermatitis). Consuming garlic in summer helps relieve summerheat, but excessive consumption damages Qi and harms the eyes. Those practicing health preservation should avoid it. Roasting single-clove garlic over moxa fire is highly effective due to its concentrated potency. For patients suffering from summerheat toxicity, chewing three or four cloves and swallowing provides immediate relief. For persistent epistaxis (nosebleed), crushed garlic applied to the sole of the foot stops the bleeding once it ceases, after which it should be wiped off. Drinking two sheng (approx. 400ml) of garlicky juice at once induces vomiting to expel intestinal parasites. It is also effective for yige (dysphagia/chest obstruction) where food cannot be swallowed, abdominal heat like fire, and extreme tenderness to touch. However, for patients with deficient stomach Qi and poor appetite, misusing this method accelerates adverse outcomes. It is contraindicated in jiaoxie (footQi/polyneuritis) and after epidemic diseases, as it may stir up residual pathogens. Those taking Yunmu (Mica) or Zhongru (Stalactite) must not consume it, as it disrupts medicinal efficacy, causing abdominal pain and diarrhea, rendering previous treatments futile. Xiaosuan (Small Garlic) treats abdominal discomfort in Huoluan (Cholera-like disorder), warms the Middle Jiao, and eliminates pathogenic obstruction and toxic vapors. The *Huangdi Neijing* states: consuming Xiaosuan and raw fish depletes Qi and Yin, causing pain in the genitalia; it should not be eaten with Jiucai (Chinese Chives), as this combination causes heaviness of the body.
