（音矿。《唐本草》）
【校正】原与骐 竭同条，今自木部分入此。
【释名】赤胶（苏恭）、紫梗。
时珍曰∶
梗是矣
【集解】恭曰∶紫 ，紫色如胶。作赤 皮及宝钿，用为假色，亦以胶宝物。云蚁于海
畔树藤皮中为之。紫 树名渴廪，骐 竭树名渴留，正如蜂造蜜也。研取用之。《吴录》所
谓赤
曰∶《广州记》云∶紫 生南海山谷。其树紫赤色，是木中津液结成，可作胡胭脂，
余滓
志曰∶按别本注言∶紫 、骐 竭二物同条，功效全别。紫 色赤而黑，其叶大如盘，
从叶上出。骐 竭色黄而赤，从木中出，如松脂也。
颂曰∶按∶段成式《酉阳杂俎》云∶紫 树出真腊国，彼人呼为勒 。亦出波斯国。木
高丈许，枝叶郁茂，叶似橘柚，经冬不凋。三月开花，白色，不结子。天有雾露及雨沾濡，
其枝条即出紫 。波斯使者所说如此。而真腊使者言∶是蚁运土上于树端作窠，蚁壤得雨露
凝结而成紫 。昆仑出者善，波斯次之。又《交州地志》亦云∶本州岁贡紫 ，出于蚁壤。
乃知与血竭俱出于木而非一物，明矣。今医家亦罕用，惟染家须之。
宗 曰∶紫 状如糖霜，结于细枝上，累累然，紫黑色，研破则红。今人用造绵烟脂，
迩来亦难得。
时珍曰∶紫 出南番。乃细虫如蚁、虱，缘树枝造成，正如今之冬青树上小虫造白蜡一
般，故人多插枝造之。今吴人用造胭脂。按∶张勃《吴录》云∶九真移风县
人视土知其有蚁，因垦发。以木枝插其上，则蚁缘而上，生漆凝结，如螳螂螵蛸子之状。人
折漆以染絮物，其色正赤，谓之蚁漆赤絮。此即紫 也。血竭乃其树之脂膏，别见木部。

(Voice sounds like "Kuang". From *Tang Bencao* [Compendium of Materia Medica of the Tang Dynasty])
[Correction] Originally listed in the same entry as Qilin Jie (Dragon's Blood), it is now moved from the Wood Section to this section.
[Names] Chi Jiao (Red Gum, Su Gong); Zi Geng (Purple Stem).
Li Shizhen says:
Calling it "Geng" is correct.
[Collected Explanations] Su Gong says: Zi Mao (Purple Resin) is purple-black and resembles gum. It can be made into red leather and precious ornaments, used as a false color dye, or to glue treasures. It is said to be produced by ants within the bark of tree vines on the seashore. The tree producing Zi Mao is called Kelin, and the tree producing Qilin Jie is called Keliu, just as bees produce honey. It is ground and taken for use. What *Wu Lu* [Records of Wu] refers to as Chi...
*Guangzhou Ji* [Record of Guangzhou] states: Zi Mao grows in the valleys of the South Sea. Its tree is purple-red; it is formed from the condensation of the tree's sap, and can be used to make Hu rouge. The remaining dregs...
*Zhi* [Local Gazetteer] states: According to notes in other editions, Zi Mao and Qilin Jie are in the same entry but have completely different efficacies. Zi Mao is red-black, with leaves as large as plates, exuding from the leaves. Qilin Jie is yellow-red, flowing from the wood, resembling pine resin.
Su Song says: According to Duan Chengshi's *Youyang Zazu*, the Zi Mao tree comes from Chenla, where locals call it Le... It also comes from Persia. The trunk is over one zhang high, with lush branches and leaves; the leaves resemble those of citrus, remaining green through winter. Flowers bloom in March, white, without fruit. When mist, dew, or rain wets the branches, they exude Zi Mao. This is what Persian envoys reported. However, Chenla envoys stated: Ants carry soil to the top of the trees to build nests; the ant soil, condensed by rain and dew, forms Zi Mao. That from Kunlun is superior; that from Persia is inferior. Additionally, *Jiaozhou Dizhi* [Geography of Jiaozhou] states: The annual tribute of Zi Mao from this prefecture comes from ant-soil. Thus, it is clear that although both Zi Mao and Xue Jie (Blood Dragon's Blood) come from trees, they are not the same substance. Currently, physicians rarely use it; only dyers require it.
Kou Zongshi says: Zi Mao resembles sugar frost, clustering on fine branches in strings, appearing purple-black, turning red when ground. Nowadays, people use it to make cotton smoke rouge, which has become rare recently.
Li Shizhen says: Zi Mao comes from the Southern Barbarian lands. It is created by tiny insects resembling ants and lice crawling along tree branches, similar to how small insects on holly trees produce white wax today; thus, many people insert branches to cultivate them. People in Wu currently use it to make rouge. According to Zhang Bo's *Wu Lu*: In Yifeng County, Jiuzhen Commandery... people observe the soil to know where ants are, then till and dig. They insert wooden branches, upon which ants climb up and secrete a lacquer-like substance that condenses, resembling mantis egg cases. People break the branches to collect the lacquer for dyeing silk floss; the color is pure red, called "Ant-Lac Red Floss." This is Zi Mao. Xue Jie is the resinous paste of its tree, see the Wood Section.
[Flavor and Toxicity] Sweet, salty, neutral, slightly toxic. Chen Cangqi says: Non-toxic.
[Indications] Evil qi in the five zang organs, metal wounds (trauma from sharp instruments), leukorrhea, resolving blood stasis, generating flesh, relieving pain. Can be combined with Qilin Jie... for treating sores and scabies; suitable for inclusion in plasters (Li...)
[Attached Prescriptions] Three new prescriptions.
Bleeding from tooth gaps: Zi Mao, Frankincense, Musk...
Postpartum blood syncope, delirium, and loss of consciousness: Use 1 liang of Zi Mao. Grind into powder. Take 2 qian bi with wine. (*Xu Family Prescribed Formulas*)
Menorrhagia, gradual emaciation and sallow complexion: Powdered Zi Mao, take 2 qian per dose, swallowed with plain warm water on an empty stomach. (*Yang's Household Formulas*)
