，夏月小润液。虏中盐乃有九种∶白盐、食盐，常食者；黑盐，主腹胀气满；胡盐，主耳聋
目痛；柔盐，主马脊疮；又有赤盐、驳盐、臭盐、马齿盐四种，并不入食。马齿即大盐，黑
盐凝是卤咸，柔盐疑是戎盐，而此戎盐又名胡盐，并主眼痛，二、三相乱。今戎盐虏中甚有
，从凉州来，芮芮河南使及北部胡客从敦煌来，亦得之，自是稀少尔。其形作块片，或如鸡
鸭卵，或如菱米，色紫白，味不甚咸，口尝气臭，正如 鸡子臭者言真。又河南盐池泥中，
自有凝盐如石片，打破皆方，青黑色，善疗马脊疮，又凝世或者。盐虽多种，而戎盐，卤咸
最为要用。又巴东朐 县北岸大有盐井，盐水自凝，生粥子盐，方一、二寸，中央突张伞形

陶隐居说：如今世俗中不再见到卤咸（天然结晶盐），只有魏国进贡的虏盐，就是河东的大盐，形状像结冰一样圆润坚硬，味道咸、苦，夏季略微湿润流液。虏地的盐有九种：白盐、食盐，是日常食用的；黑盐，主治腹胀气满；胡盐，主治耳聋、目痛；柔盐，主治马脊疮；还有赤盐、驳盐、臭盐、马齿盐四种，都不用于食用。马齿盐即大盐，黑盐凝结的就是卤咸，柔盐怀疑是戎盐，而这种戎盐又名叫胡盐，都主治眼痛，说法二三互相混乱。如今戎盐在虏地很有，从凉州来，芮芮河南使者及北部胡客从敦煌来，也能得到它，只是变得稀少罢了。它的形状成块片状，有的像鸡鸭蛋，有的像菱米，颜色紫白，味道不是很咸，口尝气味臭，正如像鸡蛋臭味那样说的才是真的。另外河南盐池泥中，自然有凝结如石片的盐，打破都是方形的，青黑色，善于治疗马脊疮，又有凝结世所罕见的。盐虽然多种，但戎盐、卤咸最为重要常用。另外巴东朐县北岸大有盐井，盐水自然凝结，生出粥子盐，大小一两寸，中央突起像伞形，也有方形像石膏、围棋子的。李云说：戎盐味苦，臭。这是海潮水浇在山石上，经久盐分凝结在石头上取来的。北海产的呈青色，南海产的呈紫赤色。又说：卤咸就是人煮盐时锅底下凝结坚硬的盐渣，这两种说法都没有详细说明。唐本注说：陶弘景称卤咸，怀疑是黑盐，这是碱土，议论如同前说，这种戎盐就是胡盐。沙州名为秃登盐，廓州名为阴土盐，生长在河岸山的背阴土石间，块头大小不固定，坚硬白色像石头，烧之不鸣响罢了。臣禹锡等谨慎按陈器说：盐药，味咸，无毒。主治眼睛红烂风赤，细细研磨用水调和点入眼中。又入腹去热烦，痰满，头痛，明目，镇心，用水研服。又主治蛇恶虫毒，疥癣，痈肿，瘰疬。以前入腹，用水消服，着于疮处正尔摩敷。生于海西南雷、罗诸州山谷。像芒硝末细，入口极冷。南人多用来敷疮肿，少有服用的，恐怕极冷，入腹伤人，暂且应当谨慎。日华子说：戎盐，平。助水脏，益精气，除五脏症结，心腹积聚，痛疮疥癣等。即西蕃所出，食者号戎盐，又名羌盐。

Salty, cold, non-toxic. Mainly treats brightening the eyes and eye pain, tonifying qi, strengthening muscles and bones, removing toxic parasites (du gu), treating heart and abdominal pain, hematuria, hematemesis, and bleeding from teeth and tongue. Also known as Hu salt. Produced at Huyan Mountain and the southeast corner of Fu Lu City in Jiuquan, Beidi of Xiqiang. Those from the North Sea are green; those from the South Sea are red. Harvested in the tenth month.
Tao Hongjing said: Nowadays, natural crystallized salt (luxian) is no longer seen in common practice. Only the prisoner's salt (luyan) presented by the Wei state, which is the large salt from Hedong, resembles frozen ice in being round and hard, with a salty and bitter taste, becoming slightly moist and fluid in summer. There are nine types of salt in the barbarian regions: white salt and edible salt, which are commonly consumed; black salt, mainly used for abdominal distension and fullness of qi; Hu salt, mainly used for deafness and eye pain; soft salt, mainly used for equine spinal sores; and four others—red salt, mottled salt, smelly salt, and horse-tooth salt—which are not used for food. Horse-tooth salt is large salt; black salt congealed is luxian; soft salt is suspected to be Rong salt. This Rong salt is also called Hu salt, both treating eye pain, leading to confusion between the second and third descriptions. Currently, Rong salt is quite available in the barbarian lands, coming from Liangzhou, and obtained by envoys from the southern river of Ruirui and northern barbarian guests from Dunhuang, though it has become scarce. Its shape is block-like or sheet-like, sometimes resembling chicken or duck eggs, or water caltrop seeds, with a purple-white color and not very salty taste. It smells foul when tasted; the true kind smells exactly like rotten eggs. Additionally, in the mud of the Henan salt pool, there naturally forms salt congealed like stone sheets, which break into squares, are blue-black, and effectively treat equine spinal sores. Although there are many types of salt, Rong salt and luxian are the most important and commonly used. Furthermore, in Baidong County, north bank, there are abundant salt wells where brine naturally congeals to produce porridge-shaped salt, one or two inches square, protruding in the center like an umbrella, or square like gypsum or Go stones. Li Yun stated: Rong salt is bitter and foul-smelling. It is formed when seawater washes over mountain rocks, and after a long time, salt condenses on the stones for collection. Those from the North Sea are green; those from the South Sea are purple-red. It was also said that luxian is the hardened salt residue condensed at the bottom of pots when people boil salt. These two explanations are not detailed. The Tang Ben Zhu noted: Tao referred to luxian, suspecting it to be black salt, which is alkali soil. Discussing as per the previous statement, this Rong salt is Hu salt. In Shazhou, it is called Toudeng salt; in Kuozhou, Yin earth salt. It grows in the shaded rocky soil between riverbanks and mountains. The blocks vary in size, are hard and white like stone, and do not crackle when burned. Minister Yuxi and others carefully noted according to Chen Cangqi: Salt medicine is salty and non-toxic. It treats red and rotting eyes due to wind-heat, finely ground and mixed with water for eye application. Internally, it clears heat and irritability, resolves phlegm-fullness, relieves headache, brightens eyes, and calms the heart, taken as a water suspension. It also treats venomous snake and insect bites, scabies, tinea, carbuncles, and scrofula. For internal use, dissolve in water and drink; for external sores, apply directly. It grows in the valleys of Leizhou and Luozhou southwest of the sea. It resembles fine mirabilite powder, feels extremely cold in the mouth. Southerners mostly use it to apply to sores and swellings, rarely taking it internally, fearing its extreme coldness may harm the interior, so caution is advised. Ri Huazi stated: Rong salt is neutral. It assists the Water Zang (Kidney), benefits essence and qi, removes five-zang accumulations, heart and abdominal masses, painful sores, scabies, etc. It originates from Xifan (Western Tibet); consumers call it Rong salt, also known as Qiang salt.
The Tu Jing details are under the Edible Salt entry.
Chen Cangqi stated: Rong salt is piled like eggs. Danfang Jingyuan stated: Rong salt comes in red and black colors. Piled like eggs, dried mercury, processed cinnabar.
Yanyi stated: Rong salt forms piles, cut like pillows, fine and white, sweet and salty taste. Its efficacy also lies in dispelling blood stasis. Enters the Kidney meridian, treating stasis-redness, dryness, and blurred vision in the eyes.
