味咸，性寒，无毒。主治十二种水肿、瘿瘤（甲状腺肿大等颈部肿块）聚结之气、疮疡。产于东海。
陶隐居说：现在只有高丽出产，用绳子捆扎像卷起的麻一样，呈黄黑色，柔软坚韧可以食用。《尔雅》说：纶（音同“伦”）像轮子，组像织带，东海有这种植物。现在的青苔、紫菜都像纶，这种昆布也像组，恐怕就是它了。凡是海中的蔬菜，都能治疗瘿瘤结气。青苔、紫菜之类也是这样。干苔性质热，柔苔性质非常冷。现在考证：陈藏器在《本草》中说：昆布，主治阴部溃烂，含在口中让汁液咽下。产于南海。叶子像手掌大，像薄苇席，紫色。臣禹锡等人谨慎按《药性论》说：昆布，臣药，有小毒。通利水道，去除面部浮肿，治疗恶疮、鼠瘰（淋巴结核）。陈藏器说：紫菜，味甘，性寒。主治下部热气烦闷，多吃令人腹痛，引发气逆，吐出白沫，喝少量热醋可以化解。萧炳说：海中的菜里有小螺子，损害人体，不可多吃。
《图经本草》在海藻条目下已有详细记载。
《唐本注》说：又有石帆，形状像柏树，治疗石淋（尿路结石）。又有水松，形状像松树，治疗溪毒（山间湿热毒邪）。陈藏器说：主治颓卵肿（睾丸肿胀）。煮汁咽下，产于南海。叶子像手大，干燥时呈紫赤色，大小很像薄苇席。陶隐居说产自新罗，黄黑色，叶子柔软细小。陶隐居解释的昆布，其实是马尾海藻。新注说：如果是瘿气，取粉末用蜜做成丸剂，含化即可自行消散。《海药本草》说：谨按《异志》记载：生于东海水中，其草顺流而生。新罗产的呈黄黑色，叶子细小，胡人采集后搓成绳索，阴干，通过船运到中国。性质温，主治大腹水肿、各种浮气以及瘿瘤气结等，效果很好。雷公说：凡是用昆布，先用破蒸笼屉同煮，去掉咸味，焙干，细切使用。每修治一斤，用大小十个蒸笼屉。与昆布一起细切，两味药各放一处，放入东流水中，从巳时煮到亥时，水随时添加，不要让水减少。《食疗本草》说：下气，久服使人消瘦。没有此病的人，不可食用。海岛的人爱吃，因为没有好菜吃，只吃这种东西。服用久了，疾病也不会产生。于是传说它对北方人有功效。北方人吃了，病都生出来了。这是因为水土不宜罢了。又说：紫菜，降热气，多吃使人腹胀。如果热气堵塞咽喉，煮汁饮用。这是海中的物产，味道仍有毒性。凡是海中的菜，所以会有损害人体的地方。《圣惠方》：治疗瘿气结核，肿胀坚硬。昆布一两，洗去咸味，捣成散剂，每次取一钱用绵包裹在好醋中浸过。含在口中咽津液，药味尽后再含。《外台秘要》：治疗颌下突然结成囊状，逐渐变大欲成瘿。以昆布、海藻等分为末，蜜丸，含如杏核大，慢慢咽汁。《千金翼方》：治疗五瘿。昆布一两，并切得像手指大，用醋浸泡，含咽汁，痊愈。
Salty in flavor, cold in nature, non-toxic. It primarily treats twelve types of edema (swelling caused by fluid retention), goiter (enlargement of the thyroid gland) and other neck masses with stagnant qi, and sores/ulcers. It grows in the East Sea.
Tao Hongjing stated: Currently, it is only produced in Goryeo (Korea). It is bundled with ropes like rolled hemp, appears yellowish-black, and is soft, tough, and edible. The *Erya* states: "Lun" (pronounced 'lún') resembles a wheel, and "Zu" resembles a woven band; these are found in the East Sea. Current green algae and laver resemble "Lun," while this Kelp resembles "Zu," suggesting they might be the same. All marine vegetables can treat goiter and stagnant qi. Green algae and laver are similar in this regard. Dried seaweed has a hot nature, while fresh/soft seaweed has a very cold nature. Current research indicates: Chen Cangqi in his *Bencao* states: Kelp treats genital ulcers; hold it in the mouth and swallow the juice. It grows in the South Sea. The leaves are palm-sized, thin like reed mats, and purple. Ministers Yu Xi et al., according to the *Yaoxing Lun*, state: Kelp is a minister herb, slightly toxic. It promotes urination, reduces facial swelling, and treats malignant sores and scrofula (tuberculous lymphadenitis). Chen Cangqi states: Laver is sweet in flavor and cold in nature. It treats lower heat and irritability; excessive consumption causes abdominal pain, induces qi rebellion, results in vomiting of white foam, which can be resolved by drinking a small amount of hot vinegar. Xiao Bing stated: Marine vegetables may contain small snails that harm the human body and should not be eaten in excess.
The *Tu Jing Ben Cao* details this under the entry for Sargassum Herba (Haisei, 海藻).
The *Tang Ben Zhu* states: There is also "Shi Fan" (Stone Sail), shaped like cypress, used to treat stone strangury (urinary calculi). There is also "Shui Song" (Water Pine), shaped like pine, used to treat stream toxicity (toxic damp-heat from mountain streams). Chen Cangqi states: It treats orchitis (testicular swelling). Boil and drink the juice; it grows in the South Sea. The leaves are hand-sized, dry into purple-red color, and are large like thin reed mats. Tao Hongjing stated it comes from Silla, is yellowish-black, and has soft, fine leaves. Tao's explanation of Kelp actually refers to Sargassum fusiforme (Mawei Haizao, 马尾海藻). The new annotation states: For goiter qi, take the powder, make pills with honey, and dissolve slowly in the mouth to eliminate it naturally. The *Hai Yao Ben Cao* states: According to the *Yi Zhi*: It grows in the waters of the East Sea, with its grass growing downstream. The Silla variety is yellowish-black with fine leaves. Hu people harvest it, twist it into ropes, dry it in the shade, and bring it to China by ship. Its nature is warm; it effectively treats massive abdominal edema, various floating qi conditions, and goiter with qi stagnation. Lei Gong stated: When preparing it, first boil it with broken steamer inserts to remove the salty taste, then bake, cut finely, and use. For every jin (500g) processed, use ten steamer inserts of varying sizes. Place the finely cut herbs separately in each insert, put them in flowing water from the east, and boil from Si hour (9-11 AM) to Hai hour (9-11 PM), adding water as needed without letting it run dry. The *Shi Liao Ben Cao* states: It directs qi downward; long-term use makes thin people thinner. Those without this condition should not eat it. People on islands love to eat it because there are no other good vegetables, so they only eat this. Long-term consumption prevents disease. Thus, it was rumored to be beneficial for northerners. However, northerners who ate it developed diseases. This is due to unsuitable local water and soil conditions. It is also said: Laver clears heat qi; excessive consumption causes bloating. If heat qi blocks the throat, boil and drink the juice. These are marine products, and their flavors still retain some toxicity. Therefore, all marine vegetables can potentially harm humans. The *Sheng Hui Fang* states: To treat goiter qi nodules that are swollen and hard: Take one liang of Kelp, wash away the saltiness, pound into a powder. Each time, take one qian (3g), wrap in silk, soak in good vinegar, hold in the mouth, swallow the saliva, and when the medicinal flavor is exhausted, repeat. The *Wai Tai Mi Yao* states: To treat sudden cyst formation under the jaw that gradually enlarges towards becoming a goiter: Mix equal parts of Kelp and Sargassum Herba (Haisei, 海藻) into powder, make honey pills, hold one the size of an apricot kernel in the mouth, and slowly swallow the juice. The *Qianjin Yi Fang* states: To treat five types of goiter: Take one liang of Kelp, cut into finger-sized pieces, soak in vinegar, hold in the mouth, and swallow the juice until cured.
