（《证类》）
【释名】紫藤香（《纲目》）、鸡骨香。
曰∶《仙传》∶拌和诸香，烧烟直上，感引鹤降。醮星辰，烧此香为第一，度 功力极
验。降真之名以此。
时珍曰∶俗呼舶上来者为番降，亦名鸡骨，与沉香同名。
【集解】慎微曰∶降真香出黔南。
曰∶生南海山中及大秦国。其香似苏方木，烧之初不甚香，得诸香和之则特美。入药
以番降紫而润者为良。
时珍曰∶今广东、广西、云南、汉中、施州、永顺、保靖，及占城、安南、暹罗、渤泥、
琉球诸地皆有之。朱辅《溪蛮丛笑》云；鸡骨香即降香，本出海南。今溪峒僻处所出者，似
是而非，劲瘦不甚香。周达观《真腊记》云∶降香生丛林中，番人颇费砍斫之功，乃树心也。
其外白皮，浓八、九寸，或五、六寸。焚之气劲而远。又嵇含《草木状》云∶紫藤香，长茎
细叶，根极坚实，重重有皮，花白子黑。其茎截置烟炱中，经久成紫香，可降神。按∶嵇氏
所说，与前说稍异，岂即朱氏所谓似是而非者乎？抑中国者与番降不同乎？
【气味】辛，温，无毒。
【主治】烧之，辟天行时气，宅舍怪异。小儿带之，辟邪恶气（李 ）。疗折伤金疮，
止血定痛，消肿生肌（时珍）。
【发明】时珍曰∶降香，唐、宋本草失收。唐慎微始增入之，而不着其功用。今折伤金
疮家多用其节，云可代没药、血竭。按∶《名医录》云∶周 被海寇刃伤，血出不止，筋如
断，骨如折，用花蕊石散不效。军士李高用紫金散掩之，血止痛定。明日结痂如铁，遂愈，
且无瘢痕。叩其方，则用紫藤香瓷瓦刮下研末尔。云即降之最佳者，曾救万人。罗天益《卫

【附方】新二。
金疮出血∶降真香、五倍子、铜花等分为末，敷之。（《医林集要》）
痈疽恶毒∶番降末、枫、乳香，等分为丸，熏之，去恶气甚妙。（《集简方》）

李时珍说：《仙传方》记载：将降真香与其他香料混合，燃烧时烟气直上，能感应引来仙鹤降落。在祭祀星辰时，焚烧此香效果最佳，其灵验功效极大。降真香的名称便由此而来。
李时珍说：民间称从海外运来的为“番降”，也称为“鸡骨”，与沉香同名。
李时珍说：降真香生长于南海山中以及大秦国（古代对罗马帝国或阿拉伯地区的泛称）。它的香气类似于苏方木，刚点燃时香味并不浓烈，与其他香料配合燃烧则特别芳香。入药以颜色紫黑且滋润的“番降”为佳。
李时珍说：如今广东、广西、云南、汉中、施州、永顺、保靖，以及占城、安南、暹罗、渤泥、琉球等地都有出产。朱辅在《溪蛮丛笑》中说：鸡骨香就是降香，原本产于海南。现在偏远溪峒地区所产的，看起来像但实际不是，质地坚硬瘦削，香味不浓。周达观在《真腊记》中说：降香生长在丛林中，外国人砍伐它费了不少功夫，因为它是树木的心材。其外层白皮厚度约为八、九寸，或者五、六寸。焚烧时气味强劲且传播得远。另外嵇含在《草木状》中说：紫藤香茎长叶细，根部极其坚实，层层有皮，花白色果实黑色。将其茎段截断放置在烟灰中，经久变成紫色香木，可以降神。按：嵇氏所说的情况，与前人的说法稍有不同，难道就是朱氏所说的“似是而非”的那种吗？还是说中国本土产的和海外进口的不同呢？
【气味】辛味，温性，无毒。
【主治】焚烧它，可以避开时行瘟疫之气，驱除住宅中的怪异邪气。小儿佩戴它，可以辟除邪恶之气（引自李杲）。治疗跌打损伤和金刃创伤，止血定痛，消肿生肌（李时珍）。
【发明】李时珍说：降香在唐代、宋代的本草著作中未被收录。唐慎微才开始将其增补进去，但没有注明其具体功用。如今治疗跌打损伤和金刃创伤的医生多用其节段，说它可以代替没药和血竭。按：《名医录》记载：周姓之人被海盗用刀砍伤，血流不止，筋脉如同断裂，骨骼如同折断，使用花蕊石散无效。军士李高用紫金散敷盖伤口，血止疼痛停止。第二天结痂如铁般坚硬，于是痊愈，而且没有留下瘢痕。询问其药方，原来是刮下紫藤香瓷瓦上的粉末研末而成。说是降真香中最好的品种，曾救治万人。罗天益《卫生宝鉴》……
【附方】新增二方。
(From *Zhenglei Bencao*)
[Names] Ziteng Xiang (Purple Vine Incense) (from *Bencao Gangmu*), Jigu Xiang (Chicken Bone Incense).
Li Shizhen states: The *Xianchuan Fang* records that when mixed with various other incenses and burned, the smoke rises straight up, capable of attracting cranes to descend. It is the premier incense for worshipping stars and planets, with extremely effective spiritual power. This is how it acquired the name "Jiangzhen" (Descending True).
Li Shizhen states: Commonly, those imported from overseas are called "Fan Jiang" (Foreign Descending), also named "Jigu", sharing the same name as Chenxiang (Agarwood).
[Collection and Explanation] Chen Shenwei states: Jiangzhen Xiang originates from the Qian South region.
Li Shizhen states: It grows in the mountains of the South Sea and in Daqin (ancient term for Rome or the Arab world). Its scent resembles Sufangmu (Sappanwood); initially, it does not smell strongly when burned, but becomes exceptionally fragrant when blended with other incenses. For medicinal use, the "Fan Jiang" that is purple in color and moist is considered superior.
Li Shizhen states: Currently, it is produced in Guangdong, Guangxi, Yunnan, Hanzhong, Shizhou, Yongshun, Baojing, as well as Champa, Annam, Siam, Brunei, and Ryukyu. Zhu Fu in *Ximan Congxiao* says: Jigu Xiang is Jiangxiang, originally originating from Hainan. Those produced in remote stream valleys today look similar but are not authentic; they are hard, lean, and not very fragrant. Zhou Daguan in *Zhenlu Ji* says: Jiangxiang grows in dense forests; foreigners expend considerable effort chopping it down because it is the heartwood of the tree. The outer white bark is eight or nine cun thick, or five or six cun. When burned, its odor is potent and spreads far. Additionally, Ji Han in *Caomu Zhuang* says: Ziteng Xiang has long stems and fine leaves, a very solid root with layered bark, white flowers, and black seeds. If its stem segments are placed in soot for a long time, they turn into purple incense capable of invoking spirits. Note: What Ji Han described differs slightly from previous accounts. Could this be what Zhu Fu referred to as "seemingly correct but actually wrong"? Or perhaps the domestic variety differs from the foreign import?
[Odor and Flavor] Acrid, Warm, Non-toxic.
[Indications] Burning it repels epidemic qi and strange phenomena in dwellings. Carrying it protects children from evil qi (cited from Li Gao). It treats fractures and metal wounds, stops bleeding, alleviates pain, reduces swelling, and generates flesh (Li Shizhen).
[Elucidation] Li Shizhen states: Jiangxiang was omitted from the materia medica of the Tang and Song dynasties. Tang Shenwei was the first to add it, without specifying its functions. Today, practitioners treating fractures and metal wounds often use its nodes, claiming it can substitute for Moyao (Myrrh) and Xuexie (Dragon's Blood). Note: According to *Mingyi Lu*, a person surnamed Zhou was cut by a pirate's blade, with blood flowing uncontrollably, tendons severed, and bones broken. Huayanshi San (Flower Stamen Stone Powder) was ineffective. Soldier Li Gao applied Zijin San (Purple Gold Powder), stopping the bleeding and pain. By the next day, the wound scabbed over like iron, healing completely without scarring. Inquiring about the prescription, it turned out to be powder scraped from Zi Teng Xiang on porcelain tiles. He claimed it was the best quality of Jiangzhen, having saved ten thousand people. Luo Tianyi's *Weisheng Baojian*...
[Attached Prescriptions] Two new prescriptions.
Metal wounds with bleeding: Jiangzhen Xiang, Wubeizi (Chinese Gallnut), Tonghua (Copper Flower) ground into equal parts powder, applied externally. (*Yilin Jiyao*)
Carbuncles and malignant sores: Fan Jiang powder, Fengxiangzhi (Styrax), Ruxiang (Frankincense) made into pills in equal parts, used for fumigation to remove foul odors effectively. (*Jijian Fang*)
