【释名】木奴。
陶弘景说：柑子，未经历霜冻时味道还酸，霜降后非常甜，所以名叫柑子。
李时珍说：汉代李衡在武陵洲上种植柑树，被称为“木奴”。
【集解】苏颂说：产自西戎的乳柑品质最佳。
陶弘景说：柑生长在岭南及江南地区，树形像橘树，果实也像橘子但更圆大，生时皮色青，熟时皮色黄赤。只有乳柑的皮入药。
孟诜说：柑有朱柑、黄柑、乳柑、石柑、沙柑。橘有朱橘、乳橘、塌橘、山橘、黄淡子。这些品种的皮都能去气调中，果实都可供食用，其中以乳柑为上品。
李时珍说：柑是南方的水果，福建、广东、温州、台州、苏州、抚州、荆州等地盛产，川蜀地区产量稍逊。柑树与橘树无异，只是刺较少。柑皮比橘皮颜色黄而稍浓，纹理稍粗且味道不苦。橘子可以久存，柑容易腐败。柑树怕冰雪，橘树稍微耐寒一些。这是柑与橘的区别。现在人们多将柑皮、橘皮混用，不可不辨别，详见橘条下。案语：韩彦直《橘谱》记载：乳柑产于温州各县，以泥山所产为最，因为其味道像乳酪而得名。当地人称之为真柑，视其他柑为假。其树枝叶婆娑，叶片纤长，花香浓郁，果实圆润端正，表皮如涂蜡般光泽，直径六七寸，皮薄味美，脉络不粘瓣，食用不留渣，一颗仅二三个核，也有全无核的，掰开时香气雾人，是柑中的极品。生枝柑，形状不圆，皮色青且粗糙，味道微酸，留在枝头可耐久存，等到味道变甘，才带叶采摘，因此得名。海红柑，树小果实极大，有的周长达到一尺，皮厚色红，可久藏，现在的狮头柑也是这一类。洞庭柑，种自洞庭山，皮细味美，成熟最早。甜柑，类似洞庭柑但更大，每颗必分八瓣，不需经霜就变黄。木柑，类似洞庭柑，表皮粗糙坚硬，瓣大汁少，所以叫木柑。朱柑，类似洞庭柑但更大，颜色极红，味道酸，人们不重视它。馒头柑，靠近蒂部隆起如馒头尖，味道香美。
【气味】甘味，大寒，无毒。苏颂说：冷。
陶弘景说：多吃使人肺冷生痰，脾冷引发顽固积块，大肠腹泻，出阴汗。
【主治】清除肠胃中的热毒，解丹石药毒，止暴渴，利小便（《开宝本草》）。
【附方】新增一方。
难产：柑橘瓤，阴干，烧至存性，研成粉末。温酒送服二钱。（出自《集效方》）

李时珍说：橘皮苦辛温，柑皮辛甘寒。外形虽然相似，但气味不同。
孟诜说：多吃令肺燥。
【主治】下气调中（孟诜）。解酒毒及酒后口渴，去除白膜，焙干研末，点汤加盐饮用（孙思邈）。治疗产后肌肤浮肿，研末酒服（孟诜）。伤寒病后因饮食或劳累复发者，浓煎汁服用（李时珍）。山柑皮：治疗咽喉痛，有效（《本草图经》）。

[Invention] Li Shizhen stated: Juhé (Citrus reticulata Seed) enters the Foot-Jueyin Liver Meridian and has the same efficacy as Qingpi (Green Tangerine Peel), thus it can treat lower back pain and hernia located in the lower body. This is not merely based on the symbolic association with the seed. The *Heji Jufang* (Formulas of the Bureau of Taiping People's Welfare Pharmacy) contains Juhé Wan (Tangerine Seed Pill) for treating various hernias, internal swelling, testicular descent, hardness like stone, or swelling leading to ulceration, which is effective. There are many varieties; see the original formula for details.
[Attached Formula] New one.
Lower Back Pain: Juhé (Citrus reticulata Seed) and Duzhong (Eucommia Bark), each 2 liang, stir-fried. Grind into powder. Take 2 qian per dose, washed down with salted wine. (*Jianbian Fang*)
Leaf
[Flavor and Nature]: Bitter, Neutral, Non-toxic.
[Indications]: Guides rebellious Qi in the chest and diaphragm, enters the Jueyin meridian, moves Liver Qi, reduces swelling and dissipates toxicity. Used for mastitis (Ru Yong) and hypochondriac pain, combined with herbs that regulate menstruation (Zhen Heng).
[Attached Formula] New one.
Lung Abscess: Green tangerine leaves, wash, crush and squeeze to obtain one cup of juice. Ingest. Recovery occurs when pus and blood are vomited out. (*Jingyan Liangfang*)
(Song Dynasty *Kaibao Bencao*)
[Names]: Munu.
Tao Hongjing said: When unripe, the citrus fruit is sour; after frost, it becomes very sweet, hence the name Ganzi.
Li Shizhen said: In the Han Dynasty, Li Heng planted citrus trees on Wuling Island, known as "Munu."
[Collected Explanations] Su Song said: Rungan from Western Regions is the best.
Tao Hongjing said: Citrus grows in Lingnan and Jiangnan. The tree resembles the tangerine tree, and the fruit resembles a tangerine but is rounder and larger. The skin is green when raw and yellow-red when ripe. Only the peel of Rungan is used medicinally.
Meng Shen said: There are Zhugan, Huanggan, Rungan, Shigan, and Shagan. There are Zhuju, Ruju, Taju, Shanju, and Huangdanzi. The peels of these varieties all regulate Qi and harmonize the middle jiao, and their fruits are edible. Among them, Rungan is the finest.
Li Shizhen said: Citrus is a southern fruit, abundant in Fujian, Guangdong, Wenzhou, Taizhou, Suzhou, Fuzhou, and Jingzhou. Sichuan produces less. The tree is no different from the tangerine tree, except having fewer thorns. The peel of citrus is yellower and slightly thicker than that of tangerine, with coarser texture and non-bitter taste. Tangerines can be stored long-term, while citrus spoils easily. Citrus trees fear ice and snow, whereas tangerine trees are slightly more resistant. This is the difference between citrus and tangerine. Nowadays, people often mix citrus peel and tangerine peel, which must be distinguished; see under the entry for Tangerine. Note: Han Yanzhi's *Ju Pu* states: Rungan comes from counties in Wenzhou, with those from Ni Mountain being the best, named so because its taste resembles milk curds. Locals call it True Citrus, regarding others as fake. Its branches are luxuriant, leaves slender, flowers fragrant, fruits round and regular, skin waxy and glossy, diameter six to seven cun, peel thin and delicious, segments do not stick to the peel, no residue left after eating, containing only two or three seeds, or none at all. Breaking it open releases a fragrant mist, making it the supreme variety. Shengzhigan grows on branches, shape not round, skin green and coarse, taste slightly sour, stays on branches for a long time, picked with leaves only when sweet, hence the name. Haihong gan has small trees but huge fruits, some up to one chi circumference, thick red skin, storable long-term; Lion Head Citrus belongs to this category. Dongting gan originates from Dongting Mountain, fine skin, beautiful taste, ripens earliest. Tiangan is similar to Dongting but larger, always eight segments, turns yellow without frost. Mugan is similar to Dongting, rough hard skin, large segments with little juice, hence "Wood". Zhugan is similar to Dongting but larger, extremely red, sour taste, not valued. Mantou gan has a bun-like protrusion near the stem, fragrant and delicious.
[Flavor and Nature]: Sweet, Greatly Cold, Non-toxic. Su Song said: Cold.
Tao Hongjing said: Overconsumption causes cold lungs and phlegm, cold spleen with stubborn masses, diarrhea, and sweating in the yin regions.
[Indications]: Clears heat and toxins in the intestines and stomach, resolves Dan-Shi drug toxicity, stops sudden thirst, promotes urination (*Kaibao Bencao*).
[Attached Formula] New one.
Dystocia: Citrus pulp, dried in shade, burned until carbonized (preserving nature), ground into powder. Take 2 qian with warm wine. (*Jixiao Fang*)
Peel
[Flavor and Nature]: Pungent, Sweet, Cold, Non-toxic.
Li Shizhen said: Tangerine peel is Pungent, Bitter, Warm; Citrus peel is Pungent, Sweet, Cold. Although they look similar externally, their flavors and natures differ.
Meng Shen said: Overconsumption dries the lungs.
[Indications]: Descends Qi and harmonizes the middle jiao (Meng Shen). Resolves alcohol toxicity and post-drinking thirst, removes white membrane, roasted, ground, taken with water and salt (Sun Simiao). Treats postpartum edema, taken as powder with wine (Meng Shen). For relapse of Shanghan disease due to diet or labor, take concentrated decoction (Li Shizhen). Shangan peel: Treats sore throat, effective (*Bencao Tujing*).
Seed
[Indications]: Used for facial masks (*Su Song*).
