（本经上品）
【气味】甘平，无毒。
【主治】主伤中，除痹下气，补五脏，虚劳羸瘦，强阴，益精。久服浓肠胃。
【核】曰∶出六安山谷，及荆襄、汉中、江左、庐州、台州、温州诸处，近以温、台者
为贵。谓其形似金钗，然气味腐浊，不若川地者，形颇修洁，气味清疏，母取美观，舍清用
浊也。丛生水旁石上，根纠结甚繁，干则白软，茎叶生皆青脆，干则黄韧。五月生苗，似竹
节，间出碎小叶。七月开淡红色花，十月结实。节旁自生根须，折之悬挂屋下，时灌以水，
经年不死，俗呼为千年润，此即蜀中所产，入药最良。一种麦斛，形似大麦，累累相连，头
生一叶，而性多寒。一种雀髀斛，茎大如雀髀，叶在茎头。一种草斛，若小草，长三四寸，
柔且韧，折之如肉而实。一种木斛，中虚如木，长尺余，色深黄而光泽。修治，去根头，酒
浸一宿，曝干，酥拌蒸之，从巳至酉，徐徐焙干。唯入汤膏，不入丸散，以质绵韧，不作末
故也。陆英为之使。恶凝水石、巴豆，畏雷丸、僵蚕。
先人博议云∶石止而不动，斛受而量满。黄色甘味平气，具土德化，有杜而不出，受而
不施，成而不生，及遂事之义，故有杜兰、禁生、石 之名。盖五中之伤，外出形骸之痹，
内以伏匿之气，故外消肌肉，而内乏阴精，此能去内外之因，而致内外之益，则五中不伤，
是为之补。久之则中藏既盛，外府自浓矣。
【 】曰∶不藉水土，缘石而生。一名禁生，虽禁犹生也。一名杜兰，此以形举，亦处
杜塞之境，犹若光风泛兰也。顾山之有石，若人之有骨，盘结之状，亦若筋膜之聚络骨节也。
斛，量名，象其能入能出也。故石斛功力，宛如胃府，运化精微，散精于肾，淫气于骨，散
精于肝，淫气于筋膜，以及从脾淫肌肉，从心淫血脉，从肺淫皮毛，何莫非水谷之源，次第
敷布于神藏，次第满溢于形藏者。设痹塞则中伤，致令胃失所司，不能下精与气，遂成神藏
之虚劳，形藏之羸瘦耳。久服则量而满，故肠胃浓。满而溢，故虚劳补，羸瘦充。设非强益
谷精，安能逐除痹塞，以续伤中乎。禁生、杜兰，深可味也。
【本经上品】
【气味】味甘，性平，无毒。
【主治】主要治疗内伤，祛除痹证、降逆气，补益五脏，治疗虚劳消瘦，强壮阴精，增益精气。长期服用可使肠胃厚实。
【考证】曰：产于六安山谷，以及荆襄、汉中、江左、庐州、台州、温州等地，近来以温州、台州的石斛为珍贵。有人说它形状像金钗，但气味浑浊，不如四川地产的石斛，四川产的形态修长洁净，气味清疏，如果只追求美观而舍弃清纯选用浑浊，那就错了。石斛丛生在水边石头上，根系纠结繁茂，干燥后呈白色柔软，茎叶生长时青翠脆嫩，干燥后变黄且坚韧。五月生苗，类似竹节，间杂生出细碎小叶。七月开淡红色花，十月结果实。节旁自行生出根须，折断后悬挂在屋檐下，时常浇水，经过一年也不会死，俗称为“千年润”，这就是蜀地所产的，入药效果最好。还有一种麦斛，形状像大麦，累累相连，顶端生有一片叶子，性质多寒。有一种雀髀斛，茎粗如鸟的大腿，叶子长在茎的顶端。有一种草斛，像小草一样，长三四寸，柔韧，折断后像肉一样坚实。有一种木斛，中间空虚像木头，长一尺多，颜色深黄且有光泽。炮制方法：去掉根头，用酒浸泡一夜，晒干，用酥油拌蒸，从巳时到酉时，慢慢焙干。只用于汤剂和膏剂，不用于丸剂和散剂，因为其质地绵韧，不能磨成粉末的缘故。陆英作为它的辅药（使药）。畏忌凝水石、巴豆，害怕雷丸、僵蚕。
先父曾广泛议论说：石头静止不动，斛受纳而量满。黄色甘味性平，具备土的德行与化育功能，有杜绝而不流出、受纳而不施予、成就而不生育，以及完成事务的含义，所以有杜兰、禁生、石[斛]的名字。大概五脏的内伤，外表现为形体的痹证，内部潜伏着郁滞之气，所以外部消耗肌肉，内部缺乏阴精，这种药能去除内外的病因，从而带来内外的益处，那么五脏就不受损伤，这叫做补益。时间久了则中焦脏腑充实，外在的六腑自然厚实了。
【某名家】曰：不依赖水土，沿着石头生长。一名禁生，虽然禁止却仍能生长。一名杜兰，这是根据形状命名的，也处于闭塞之境，就像光风中的兰花一样。顾念山中有石头，就像人中有骨骼，盘结的形状，也像筋膜聚集联络骨节一样。斛，是量器的名称，象征它能进入也能排出。所以石斛的功效，宛如胃腑，运化精微物质，将精气散布于肾，使湿气滋养骨骼；将精气散布于肝，使湿气滋养筋膜；以及从脾散布湿气于肌肉，从心散布湿气于血脉，从肺散布湿气于皮毛，这些无不是水谷精微的来源，依次敷布于神藏（五脏），依次满溢于形藏（六腑）。如果发生痹塞则导致内伤，致使胃失去其职能，不能向下输送精气，于是形成神藏的虚劳，形藏的消瘦罢了。长期服用则量器装满，所以肠胃厚实。装满而溢出，所以虚劳得到补益，消瘦得以充盈。如果不是通过增强和补充水谷精气，怎么能驱逐除去痹塞，来接续修复内伤呢？禁生、杜兰，含义深远值得品味。
[Shangpin Category of the Classic of Materia Medica]
[Odor and Flavor] Sweet in taste, neutral in nature, non-toxic.
[Indications] Primarily treats internal injury (shangzhong), dispels bi-syndrome (bi-zheng) and directs rebellious qi downward, tonifies the five zang organs, treats consumptive disease with emaciation (xulao leishou), strengthens yin essence, and benefits jing essence. Long-term consumption thickens the intestines and stomach.
[Verification] It is said: Produced in the valleys of Lu'an, as well as Jingxiang, Hanzhong, Jiangzuo, Luzhou, Taizhou, Wenzhou, etc. Recently, those from Wenzhou and Taizhou are considered precious. Some say its shape resembles a gold hairpin, but its odor is turbid, unlike those from Sichuan, which have an elegant and clean shape and a clear, sparse odor. If one only seeks aesthetic beauty while abandoning purity for turbidity, that would be a mistake. Dendrobium grows in clusters on rocks by the water, with tangled and abundant roots; when dry, they are white and soft. The stems and leaves are green and crisp when growing, turning yellow and tough when dry. In May, shoots emerge resembling bamboo nodes, interspersed with small fragmented leaves. In July, pale red flowers bloom; in October, fruits form. Roots sprout naturally from the nodes; if broken and hung under eaves, watering them occasionally allows them to survive for years. Commonly known as "Thousand-Year Moisture" (Qiannian Run), this is the variety produced in Shu, which is best for medicinal use. There is also a type called Maihu (Wheat Dendrobium), shaped like wheat grains, connected in clusters, with a single leaf at the head, possessing a cold nature. There is Qubi Hu (Sparrow Thigh Dendrobium), with stems as thick as a sparrow's thigh, leaves at the stem tip. There is Cao Hu (Grass Dendrobium), resembling small grass, 3-4 cun long, soft and tough, solid like meat when broken. There is Mu Hu (Wood Dendrobium), hollow inside like wood, over a chi long, deep yellow in color and glossy. Processing: Remove the root head, soak in wine overnight, sun-dry, mix with su (animal fat/butter) and steam from Si hour to You hour, then slowly bake dry. It is used only in decoctions and pastes, not in pills and powders, because its texture is fibrous and tough, making it unsuitable for grinding into powder. Luying (Euphorbia humifusa) serves as its assistant herb (shi). It is incompatible with Ningshuishi (Calcitum) and Badou (Crotonis Fructus), and fears Leiwan (Omphalia lapidescens) and Jiangcan (Bombyx Batryticatus).
My late father discussed extensively: Stone remains still and unmoving; Dendrobium receives and fills to capacity. Yellow color, sweet taste, and neutral nature embody the virtue and transformation of Earth. It has the meaning of blocking without leaking, receiving without giving, completing without generating, and fulfilling tasks. Hence the names Dulán (Du Lan), Jinsheng (Jin Sheng), and Shi [Hu]. Generally, internal injury to the five zang organs manifests externally as physical bi-syndrome and internally as latent stagnant qi. Thus, external muscles are consumed, and internal yin essence is deficient. This herb removes both internal and external causes, thereby bringing internal and external benefits, so the five zang organs are not injured; this is what is meant by tonification. Over time, the central zang organs become abundant, and the exterior fu organs naturally thicken.
[A Master] said: It does not rely on soil or water, but grows along stones. One name is Jinsheng (Forbidden Growth), meaning it grows even when forbidden. Another name is Dulán, named after its shape, also residing in a blocked environment, yet appearing like orchids in a gentle breeze. Consider that mountains having stones is like humans having bones; their knotted appearance is similar to fascia gathering and connecting bone joints. "Hu" is a unit of measurement, symbolizing its ability to enter and exit. Therefore, the efficacy of Dendrobium is akin to the Stomach organ, transforming and transporting refined essences, scattering essence to the Kidney to nourish bones, scattering essence to the Liver to nourish fascia, and similarly from the Spleen nourishing muscles, from the Heart nourishing blood vessels, and from the Lung nourishing skin and hair. All these are sources of grain and water essence, sequentially distributed among the Shen Zang (Spirit Stores/Five Zang) and sequentially overflowing into the Xing Zang (Form Stores/Six Fu). If bi-stagnation occurs, it leads to internal injury, causing the Stomach to lose its function, unable to descend essence and qi, resulting in deficiency-consumption of the Shen Zang and emaciation of the Xing Zang. Long-term consumption fills the measure, thus thickening the intestines and stomach. When full and overflowing, deficiency-consumption is tonified, and emaciation is filled. Without strengthening and benefiting the grain essence, how could one drive out bi-stagnation to repair internal injury? The meanings of Jinsheng and Dulán are profound and worthy of contemplation.
