肺主皮毛，其合阳明（大肠）。故发汗解肌，以通上下阳气（仲景白通汤、通脉四逆汤并加
之，以通脉回阳），益目睛（白睛属肺），利耳鸣，通二便（时珍曰∶葱管吹盐入玉茎中，治
小便不通，及转脬危急者极效）。治伤寒头痛，时疾热狂，阴毒腹痛（阴证厥逆，用葱白安
脐上熨之）。气通则血活（气为血帅），故治吐血衄血，便血痢血（《食医心镜》∶葱煮粥食，
治赤白痢，薤粥亦良），折伤血出（火煨研封，止痛无瘢），乳痈风痹，通乳安胎（妇人妊娠
伤寒，葱白一物汤，发汗而安胎，加生姜亦佳。《删繁方》∶合香豉、阿胶，治胎动）。通气

初起便用独头大蒜，切片灸之，三壮一易，百壮为率。但头项以上，切不可灸，恐引气上，

火满背高阜，头孔百数，则毒外出，否则内逼五脏而危矣。《纲目》曰∶《精要》谓头上毒

无妨也）。然其气熏臭，多食生痰动火，散气耗血，损目昏神（五荤皆然，而蒜尤甚。《楞严

Light in nature, it releases the exterior and harmonizes the interior, unblocks Yang Qi, and invigorates blood circulation.
Raw garlic chives (Congbai) are pungent and dispersing; cooked ones are sweet and warm (Tao Hongjing stated: White chives are cool, green chives are hot; green chives should not be used in decoctions for treating Cold Damage). The exterior is solid while the interior is hollow, making it a vegetable corresponding to the Lung meridian.
The Lung governs the skin and hair, and its interior-exterior pair is the Large Intestine (Yangming Meridian). Therefore, it induces sweating to release the muscle layer, and unblocks the Yang Qi of the upper and lower body (Zhang Zhongjing added Congbai to Baitong Decoction and Tongmai Sini Decoction to unblock vessels and restore Yang), benefits the eyes (the sclera belongs to the Lung), relieves tinnitus, and promotes the free flow of urination and defecation (Li Shizhen stated: Inserting a chive tube into the urethra and blowing salt into it is extremely effective for treating urinary retention and critical cases of bladder torsion). It treats headache caused by Cold Damage, mania due to epidemic febrile diseases, and abdominal pain from Yin toxicity (for Yin syndrome with cold extremities, apply Congbai on the navel and moxa or iron it). When Qi flows freely, Blood circulates actively (Qi is the commander of Blood); thus, it treats hematemesis, epistaxis, hematochezia, and bloody dysentery (Food Doctor's Heart Mirror recorded: Eating chive porridge treats red and white dysentery; eating Allium macrostemon porridge is also good). For traumatic injuries with bleeding, fire-roast and powder it for external application to stop pain without scarring. It treats breast abscesses and wind-bi syndromes, promotes lactation, and calms the fetus (For pregnant women suffering from Cold Damage, a single-ingredient Chive White Decoction induces sweating and calms the fetus; adding fresh ginger is also excellent. Shanfan Fang recorded: Combined with Fermented Soybean Paste and Donkey-hide Gelatin, it treats restless fetus). Because it unblocks Qi, it can detoxify, neutralizing drug poison, fish and meat poison, earthworm poison, and dog bite poison. It suits various foods, hence called "Vegetable Elder" and "Harmonizing Grass". Use the white part with roots attached; sometimes the green part is used. Consuming it with honey is fatal; consuming it with dates causes illness (Baiyi Fang recorded: For patients with external hemorrhoids, first fumigate and wash with a decoction of Sparganii Rhizoma, then apply a mixture of green chive juice and honey, which feels as cool as ice. Duxing Fang recorded: For edema and swollen feet, boil chives in water and soak the affected area three to five times daily for best results).
Zhang Qian brought seeds from the Western Regions, introducing them to China, so it is also known as Hu Suan (Garlic).
Pungent and warm. It opens the stomach and strengthens the spleen, unblocks the Five Zang organs, and reaches all orifices (Any substance that is extremely odorous or fragrant can unblock orifices). It dispels cold-dampness, resolves summerheat, wards off plagues, reduces carbuncles and swellings (mash and mix with sesame oil for topical application), breaks up masses and accumulations, digests meat, and kills snake, insect, and gu poisons. It treats coma due to heatstroke (mash and take warm with dijiang [earth slurry]). For intractable epistaxis, mash and apply to the sole of the foot to guide heat downward. For Guan Ge syndrome (obstruction of upper and lower pathways), mash and insert into the anus to open the pylorus. Applied to the umbilicus, it reaches the Lower Jiao, reduces edema, and promotes urination and defecation. Slice it, burn mugwort, and moxa for all carbuncles, malignant sores, and swollen nodules. Single-clove garlic is particularly effective (Li Xun stated: Moxibustion for carbuncles and ulcers is superior to other medicines. This is because heat-toxin stagnates in the middle jiao, blocking upper and lower passages; the toxic vapors must be vented before resolution. At the onset, use single-clove garlic, slice it, and moxa; change every three applications, with one hundred applications as a standard limit. However, never moxa the head and neck region, as it may draw Qi upward and cause greater disaster. Shi Yuan stated: There were cases of eight hundred applications, using about one sieve of mugwort. Initially, the necrotic tissue did not hurt; only when reaching healthy flesh did pain occur. By night, the fire illuminated the high points of the back, with hundreds of holes in the head, allowing toxins to exit externally; otherwise, they would press inward against the Five Zang, leading to danger. Compendium of Materia Medica stated: Jingyao claimed head toxins cannot be moxa-ed, which is incorrect. The head is the gathering place of all Yang meridians; mugwort cones should be small like peppercorns, and three to five applications per point suffice. Additionally: Li Dongyuan moxa-ed Yuan Haowen's brain carbuncle using cones as large as two nuts, applying one hundred applications until pain was felt, leading to recovery. From this, it can be inferred that for head toxins that do not hurt, larger cones and more applications are acceptable). However, its odor is pungent and foul; excessive consumption generates phlegm and fire, dissipates Qi, depletes Blood, and impairs vision and spirit (This applies to all Five Pungents, but especially garlic. Sutra of Perfect Enlightenment stated: Cooked Five Pungents provoke lust, while raw ones increase anger; therefore, Buddhists abstain from them. Buddhism classifies Garlic, Small Garlic, Asafoetida, Ci Cong (Winter Scallion), and Ge Cong (Mountain Scallion) as the Five Pungents. Ci Cong refers to winter scallions; Ge Cong refers to mountain scallions; Asafoetida is a Western Region vegetable, said to be equivalent to Coriander in China. Taoism classifies Chinese Chives, Macrostemon, Garlic, Coriander, and Rapeseed as the Five Pungents. Rapeseed refers to Brassica napus). Avoid consuming with honey.
