(Micangxiang / Zhan Sugar Fragrance) Properties are slightly warm. It treats wind-water toxic swelling, removes malignant qi and latent corpse-possession qi (Fu Shi).

Tao Hongjing stated: This fragrance is essential for incense blenders (Xiang Jia), but is not formally used in medicine. It is only used to treat malignant nodules and toxic swellings. Micangxiang originates from Jin'an and Cenzhou. The truly pure and authentic grade is hard to obtain; it is often adulterated with its bark and the excrement of wood-boring insects. Only those that are soft are considered superior. Other fragrances do not have issues of authenticity but differ in refinement and coarseness.

*Haiyao Bencao* stated: Noururexiang (Nipple Fragrance/Frankincense), according to *Guangzhi*, originates from the South Sea. It is resin from Persian pine. Those that are purple-red and like cherries are of the highest grade. Immortal formulas often use it for Bigu (grain avoidance), and additionally treat deafness, stroke, lockjaw with inability to speak, and effectively treat women's blood and qi disorders. It can make rouge wine turn red and transparent; those that are red and transparent are superior. *Jianyao Jizhong* formula for inducing labor: Take one fen of yellow, high-quality Ruxiang, grind finely into powder, mix evenly with sow's blood, form pills the size of Sophora seeds. Take five pills per dose, washed down with wine. *Boji Fang* treats fetus death in the womb. Take yellow, high-quality Ruxiang, mix with pig heart blood collected at noon on Dragon Boat Festival or on New Year's Eve, grind into pills the size of a cockle. Store in a red silk bag and hang on the door. If a patient presents symptoms, have them dissolve one pill in wine and swallow. Another formula treats acute and chronic convulsive diseases (Jing Feng). Take half liang of Ruxiang and half liang of Kansui (Radix Euphorbiae Kansui), grind together finely. Take half qian per dose, mixed with Ruxiang decoction or urine, which is excellent. *Lingyuan Fang* treats Onychocryptosis (Ingrown Nail/Jia Ju) where flesh wraps the nail with pus and blood, causing persistent pain. For this condition, the nail embedded in the flesh must be removed; even without treatment, it may heal. If an ulcer has formed and does not heal, use this method: apply equal parts of Ruxiang powder and calcined Vitriol (Danfan) topically; the necrotic flesh will disappear and healing will occur. Shen Kuo (Shen Cunzhong) believed Ruxiang is identical to Xunluxiang. Those shaped like nipples are called Ruxiang; those flattened against the ground are called Taxiang. *Danfang Jingyuan* refers to Ruxiang as "Yatong" (Dumb Copper).
