今人皆合壳用为分两，此乃应破取仁秤之。医方唯以疗眼。《仙经》以合守中丸也。臣禹锡

似枸杞而尖长，花白，子红紫色，附枝茎而生，类五味子。六月成熟，五月、六月采实，去

味甘，性温或微寒，无毒。主治心腹部的邪气结聚之气，能明目，治疗目赤肿痛、因疼痛受伤而流泪、眼睑肿胀溃烂、鼻部疾病（此处原文可能有脱字，通常指鼻渊或鼻塞等），以及心下痰饮痞块之气。长期服用可轻身益气，使人不感饥饿。产于函谷川谷及巴西地区。
陶隐居说：现在药材多从北方运来，据说出产于彭城一带。形状像乌豆大小，圆形而扁平，有纹理，状似胡桃或桃核。现在人们都连壳一起称量作为剂量，这应当是破开取仁后称重。医方中只用来治疗眼病。《仙经》中将其配合用于守中丸。臣禹锡等人谨按蜀本草图经记载：树木生长，叶子细长类似枸杞但更狭长。花白色，果实附着在茎上生长，呈紫红色，大小如五味子。茎上有很多细刺。六月成熟。现在出产于雍州。五月、六月采集，晒干。药性论记载：蕤仁，为使者药。又名堪。能治疗鼻衄（鼻出血）。
图经记载：蕤核，产于函谷川谷及巴西，现在河东地区也有。这种树高五到七尺，茎上有刺。叶子细长类似枸杞但尖端较长，花白色，果实红紫色，附着在枝茎上生长，类似五味子。六月成熟，五月、六月采集果实，去掉核和壳，阴干。古今方剂只用它来治疗眼病。刘禹锡《传信方》中记载的方法最为奇特。说：眼睛受风流泪发痒，或者生翳膜，或者发红，所有情况都主治。取宣州黄连捣碎筛成粉末，蕤核仁去皮碾成膏，因为此性质稍湿，所以末药不能太干。与黄连等分量混合，取无病的干枣三枚，切去顶部少许保留，去掉枣核，用这两种药物填满其中，再将切下的枣头盖回原处，用少量棉布包裹，以薄棉为佳。用大茶碗量的半碗水，在银器中，用文火武火交替煎取约一个鸡蛋大小的药液，用棉布过滤，待冷却后点眼，万无一失。前后试验数十人都有效，现在医生也多使用且见效，所以附记于此。
雷公说：凡是使用，先用汤浸泡去皮、尖，掰成两片。用芒硝、木通草两味药，和蕤仁同煮一伏时（约8小时）后沥出，去掉各种药物取出蕤仁，研成膏，随意加减加入药中使用。每次处理四两，用芒硝一两，木通草七两。陈藏器记载：蕤子，生用或熟用可治足睡不眠（失眠）。
Rui He (Prunus persica var. ansu Seed)
Sweet in taste, warm or slightly cold in nature, non-toxic. It primarily treats evil qi stagnation and accumulation in the heart and abdomen, brightens the eyes, treats redness of the eyes, pain-induced tearing, swelling and ulceration of the eyelids, nasal disorders, and phlegm-stagnation palpitations in the epigastrium. Long-term consumption lightens the body, benefits qi, and prevents hunger. It grows in Hangu Valley and Baxi.
Tao Hongjing stated: Currently, it comes from the north, said to originate from the Pengcheng area. Its shape is like a black soybean, round and flat, with textures, resembling walnut kernels or peach pits. Nowadays, people weigh it with the shell included for dosage; this should be weighed after cracking open to take the kernel. Medical prescriptions use it solely for treating eye diseases. The *Immortal Classics* combine it into Shouzhong Wan (Guarding the Center Pill). Minister Yuxi and others respectfully note according to the *Shu Ben Tu Jing*: It grows on trees, leaves are slender like goji berries but narrower and longer. Flowers are white, fruits grow attached to stems, purple-red in color, as large as Schisandra chinensis fruit. Stems have many fine thorns. It ripens in June. It is currently produced in Yongzhou. Collected in May and June, dried in the sun. *Yao Xing Lun* states: Rui Ren (kernel), serves as a guide drug. Also known as Kan. It can treat epistaxis (nosebleed).
*TU JING* records: Rui He grows in Hangu Valley and Baxi, and is now also found in Hedong. The tree is five to seven chi high, with thorns between stems. Leaves are slender like goji berries but pointed and long, flowers are white, fruits are red-purple, growing attached to branches and stems, resembling Schisandra chinensis fruit. It matures in June; fruits are collected in May and June, kernels and shells removed, and dried in shade. Ancient and modern formulas use it only for treating eye diseases. Liu Yuxi's *Chuan Xin Fang* describes the most unique method. It says: For wind-tearing and itching of the eyes, or formation of corneal opacities (nebula), or redness, it treats all these conditions. Take Huanglian (Coptidis Rhizoma) from Xuanzhou, pound and sieve into powder; take Rui Ren kernel, remove skin, and grind into paste. Because its nature is slightly moist, the powder must not be too dry. Mix equal parts of Huanglian powder and Rui Ren paste. Take three dry dates without disease, cut off a small portion of the top and keep it aside, remove the pit, fill the cavity completely with the two substances, replace the cut date top, wrap tightly with a small amount of cotton cloth (thin cotton is best). Use half a bowl of water measured by a large tea bowl, decoct in a silver vessel using alternating mild and strong heat until reduced to the volume of one chicken egg. Filter through cotton cloth, wait until cool, and instill into eyes. This is infallible. Dozens of trials before and after were effective; nowadays physicians also use it frequently with good results, so it is appended here.
Lei Gong said: Whenever used, first soak in hot water, remove skin and tips, split into two halves. Use Mangxiao (Natrii Sulfas) and Mutong Cao (Akebiae Caulis) together with Rui Ren, boil together for one fu period (approx. 8 hours), then drain. Remove other drugs, take out Rui Ren, grind into paste, and add to medicines as desired. For every four liang processed, use one liang of Mangxiao and seven liang of Mutong Chen. Chen Cangqi recorded: Rui Zi, raw or cooked, treats excessive sleepiness and insomnia.
