\r安息香\pj327.bmp\r
味辛、苦，气平。无毒。惟生海外，亦系木脂。因香辟邪，土人呼为辟邪树也。七
月七日，裂其树皮，胶脂如饴，随即涌出。坚凝成块，其色黄黑。烧烟鬼惧神欢，研服邪驱
恶逐。鬼胎能下，虫毒可消。
味甘，气温。无毒。来从西域，卖自广东。气极芬香，色乃紫赤。或云∶系诸香汁
，煎合成就。一说∶是狮子屎，故饰其名。诸论纷纭，难指孰是。今市卖者，多如膏油。辟
诸恶，杀鬼物精邪；去三虫，除虫毒痫 。仍禁梦魇，尤通神明。
\r龙脑香\pj328.bmp\r
（即冰片） 味辛、苦，气温、微寒。无毒。来从海舶，出自波斯。木直长类杉，皮有
甲错；枝傍生发叶，背白正圆。香即木脂结成，状若梅花细瓣。片片洁净，气甚熏人。
市家多用番硝混搀，不可不
细择也。（番硝质重色苍，如砂细碎。龙脑轻浮洁白，片片相侔。细
草务加。（不致耗蚀。）目热
赤疼，调膏点上即止；喉痹肿塞，擂末吹入立消。疳毒生管中，连敷渐殁。（和眼药敷。）舌
胀退场门外，多掺自收。（病重

乎？
味辛、苦，气平。无毒。只产于海外，也是树木的树脂。因为香气能驱避邪气，当地人称之为辟邪树。七月七日，剥开树皮，胶脂像糖稀一样，随即涌出。凝固成块，颜色黄黑。燃烧时烟雾缭绕，鬼怪害怕神灵欢喜；研末服用可驱邪除恶。能排出鬼胎，消除虫毒。
味甘，气温。无毒。来自西域，在广东售卖。气味极其芬芳，颜色紫赤。有人说：是各种香汁煎煮混合而成。另一说：是狮子粪便，所以给它装饰名字。各种说法纷纭，难以确定哪一个是正确的。现在市场上卖的，多呈膏油状。能驱避各种恶气，杀死鬼物精邪；去除三虫，消除虫毒引起的癫痫。还能禁止梦魇，尤其能通神明。
（即冰片） 味辛、苦，气温、微寒。无毒。从海船运来，出自波斯。树木笔直修长类似杉树，树皮有鳞片状裂纹；枝条旁生发出叶子，叶背白色正圆。香气是木脂凝结而成，形状像梅花细瓣。片片洁净，气味非常熏人。市售商家多用番硝掺杂，不可不仔细挑选。（番硝质地重颜色青苍，如砂粒般细碎。龙脑轻浮洁白，片片相等。细草务必添加。（以免损耗。）眼睛发热红肿疼痛，调成膏药点上即可停止；喉痹肿胀堵塞，研磨成末吹入立刻消除。疳毒生在耳管中，连续敷用逐渐消失。（配合眼药敷用。）舌头肿胀退到嘴门外，多掺入自会收回。（病情重的，用五钱才能痊愈。）还能治疗小儿痘疮，心烦狂躁胡言乱语。取研磨细末，用猪心血做丸。浓煎紫草葺汤，送下芡实大小的药粒。竟然能使痘疹发透，更能安定心神。龙脑油出产于佛誓国，钻树取得，摩治一切风气。根下的清液，又名膏香。能驱逐风涎，可以开通关窍。
（陈嘉谟）按语：丹溪说：龙脑属火，世人只知道它寒而通利，然而没达到它热而轻浮飞越的特性。《局方》只是喜欢香气而重视细致，动辄与麝香同用，作为桂枝附子的辅助。然而人身之阳易动，阴易亏，希望思考这一点。节斋又说：龙脑大辛善走，所以能散热，通利结气。医方中目痛、喉痹、下疳多用它的，是取其辛散的作用。人想死的人吞服它，气散尽也。世人误以为寒，不知道辛散性甚，似乎凉耳。诸香皆属阳，岂有香之至者，而反寒乎？
Anxi Xiang (Styrax)
Taste: Acrid, Bitter. Nature: Neutral. Non-toxic. It grows only overseas and is also a tree resin. Because its fragrance repels evil spirits, locals call it the "Evil-Repelling Tree." On the seventh day of the seventh lunar month, the bark is split, and the gum resin oozes out like malt syrup. It solidifies into lumps, yellowish-black in color. When burned, the smoke frightens ghosts and pleases deities; when ground and taken orally, it drives away evil and expels malignancy. It can induce the expulsion of "ghost fetus" (abnormal uterine growths) and eliminate insect poison.
Suhe Xiang (Styrax Benzoin / Styrax Tonkinensis)
Taste: Sweet. Nature: Warm. Non-toxic. It comes from the Western Regions and is sold in Guangdong. Its aroma is extremely fragrant, and its color is purple-red. Some say it is made by decocting and mixing juices of various aromatics. Another theory says it is lion feces, hence its embellished name. Various theories abound, making it difficult to determine which is correct. Those currently sold in the market are mostly like paste or oil. It repels all kinds of evil qi, kills ghostly entities and evil spirits; eliminates three types of intestinal parasites, and removes insect poison causing epilepsy. It still prevents sleep paralysis (nightmares), and especially promotes clarity of the spirit.
Longnao Xiang (Borneol)
(Also known as Bingpian) Taste: Acrid, Bitter. Nature: Warm, slightly cold. Non-toxic. It arrives via sea ships and originates from Persia. The tree is straight and long, resembling cedar, with scaly bark; branches grow sideways producing leaves that are white on the back and perfectly round. The fragrance is formed by the condensation of tree resin, resembling fine petals of plum blossoms. Each piece is clean, and the aroma is very pungent. Merchants often mix it with foreign saltpeter (fanxiao), so careful selection is essential. (Foreign saltpeter is heavy and dark green, finely granular like sand. Borneol is light, floating, pure white, and each piece is uniform. Fine herbs must be added carefully to prevent loss.) For heat-induced redness and pain in the eyes, applying it as a paste stops the pain immediately; for throat obstruction (houbi) with swelling and blockage, grinding it into powder and insufflating it eliminates the condition instantly. For gan poison (chronic ulcerative disease) growing in the ear canal, continuous application gradually resolves it (combined with eye drops applied externally). For tongue swelling protruding outside the mouth, adding it causes retraction (for severe cases, use 5 qian to achieve cure). It also treats childhood smallpox accompanied by mental restlessness, mania, and delirious speech. Take the finely ground powder, form pills with pig heart blood. Decoct Zicao (Arnebiae Radix seu Cortex) thickly, and swallow the pill the size of a water chestnut. It effectively promotes the eruption of the rash and stabilizes the mind. Longnao oil is produced in Fo Shi Guo (Srivijaya/Foshi region); it is obtained by drilling trees and massaged to treat all wind conditions. The clear liquid from the roots is also called Gao Xiang (Ointment Fragrance). It can drive out wind-phlegm and open orifices.
(Chen Jiamo) Commentary: Danxi stated: Borneol belongs to Fire. The world knows it as cold and promoting unblocking, but fails to realize its hot, light, floating, and soaring nature. *Ju Fang* (*Tai Ping Hui Min He Ji Ju Fang*) merely favors its fragrance and values its fineness, often using it together with Shexiang (Moschus) as an assistant to Guizhi (Cinnamomi Ramulus) and Fuzi (Aconiti Lateralis Radix Praeparata). However, human Yang qi is easily disturbed, and Yin is easily deficient; one should ponder this. Jiezai further stated: Borneol is highly acrid and moves rapidly, thus it can dissipate heat and unblock stagnant qi. Medical formulas for eye pain, throat obstruction, and chancre (xia gan) use it frequently, taking advantage of its acrid dispersing property. If a person wishing to die swallows it, their Qi will scatter completely. People mistakenly consider it cold, not realizing its strong acrid dispersing nature makes it seem cool. All aromatics belong to Yang; how could the most aromatic substance be contrary to cold?
