枫香脂
味辛、苦，性平，无毒。主治瘾疹（风团伴瘙痒的皮肤病）、风痒、浮肿和齿痛。又名白胶香。其树皮，味辛，性平，有小毒。主治水肿，能利下焦水气，需煮汁服用。各地大山中都有生长。
《唐本草》注解说：树高大粗壮，叶子呈三角形。商州、洛州一带多有生长。五月在树上砍出坑穴，十一月采集树脂。（此条为《唐本草》新增附注）
臣禹锡等人谨按：蜀地版本的《本草》将枫香、脂、皮分为三条记载，主治功效略有不同。注释中说：据王劭《广轩辕本纪》记载：黄帝时期有类似白杨但枝条分叉的树。其树脂落入地下千年变成琥珀。《图经》说：树高大粗壮，木质肌理坚硬，叶子呈三角形且有香气。《尔雅》疏证说：《说文解字》记载：枫木叶子浓密，枝条柔弱，容易摇动。又名[缺字]。郭璞注：叶子圆形且分叉有香气，就是现在的枫香。《南方草木状》说：枫香树的果实大如鸭蛋。二月开花并连着结果，八、九月成熟，晒干后可燃烧。只有九真郡出产。陈藏器说：枫皮除了原有功效外，性质涩滞，能止住痢疾。苏恭说能利下水肿，但水肿并非涩药所治，苏恭的说法有误。又说有毒，更证明了之前的谬误。用水煎服是治疗下痢最好的方法。日华子说：枫皮能止霍乱、刺风、冷风。煎汤洗浴可治之。
《图经》说：枫香脂，旧籍未记载其出产州郡，只说所在大山皆有，现在南方及关陕地区多有生长。形状像白杨，非常高大粗壮。叶子圆形且分叉，有的呈三角形且有香气。二月有花，白色。接着连枝结实，大如鸭蛋。八月、九月成熟，晒干后可燃烧。《南方草木状》说：枫实只有九真郡有。使用它有神奇效果，是难得之物。其树脂称为白胶香，五月砍成坑穴，十一月采集。其皮性质涩滞，能止痢疾。用水煎饮。《尔雅》称枫为[缺字]，说天风吹过时就会鸣响。《说文解字》说：枫木，叶子浓密枝条柔弱容易摇动。汉代宫殿中多种植它。到了霜降后，叶子变红可爱，所以诗人多称颂它。任昉《述异记》说：南方有枫子鬼。老枫木长成人的形状，也叫灵枫，其实是树瘤瘿节。至今越地巫师得到这种树瘤，雕刻成鬼神形象，可以招致灵异。在下沉香条目下有提到枫香，治疗风邪引起的瘾疹瘙痒毒素。与此相似，即同一种东西。
简要济众方：治疗吐血不止。白胶香不限分量，细细研磨成散剂。每次服用二钱，用新汲取的冷水调服。陶弘景说：枫树上的菌类，吃了让人笑个不停，用地浆解毒。《通典·南蛮记》：枫脂变成琥珀，在地上旁边不长草木，深挖八九尺，大如槲树根，削去皮就形成了。起初像桃胶，形成后变坚硬。宋齐丘《化书》说：老枫木化为羽人。
《衍义》说：枫香，与松脂都可以冒充乳香，尤其需要区别。枫香微黄白色，烧起来更能辨别真伪。兼能治疗风邪引起的瘾疹瘙痒毒素。用水煎煮，趁热炸洗患处。
Fengxiang Zhi (Liquidambar Resin)
Taste: Acrid, Bitter. Nature: Neutral. Non-toxic. Main indications: Urticaria (wind-driven wheals with itching), wind-induced pruritus, edema, and toothache. Also known as Baijiaoxiang (White Gum Resin). Its bark tastes acrid, is neutral in nature, and has slight toxicity. Main indications: Edema; promotes the downward movement of water qi; decocted in water for use. It grows in large mountains everywhere.
The *Tang Bencao* commentary states: The tree is tall and robust, with triangular leaves. It is abundant in the Shang and Luo regions. In May, pits are cut into the tree; in November, the resin is collected. (This note was added in the *Tang Bencao*).
Min Yuxi et al. carefully examined: In the Shu edition of *Bencao*, Fengxiang, its resin, and its bark are listed as three separate entries with slightly different main indications. The commentary notes: According to Wang Shuo's *Guang Xuanyuan Benji*: During the time of the Yellow Emperor, there was a tree resembling white poplar but with forked branches. Its resin turns into amber after being buried underground for a thousand years. The *Tujing* states: The tree is tall and robust, with hard wood texture, triangular leaves that are fragrant. The commentary on *Erya* states: The *Shuowen Jiezi* records: "Fengmu has dense leaves and weak branches that sway easily." It is also named [missing character]. Guo Pu's annotation: "Leaves are round and forked with fragrance; this is the current Fengxiang." The *Nanfang Caomu Zhuang* states: The fruit of the Fengxiang tree is as large as a duck egg. Flowers appear in February and bear fruit continuously; they ripen in August or September and can be dried for burning. It is found only in Jiuzhen Commandery. Chen Cangqi states: Besides its original functions, Fengpi (Feng bark) is astringent and stops dysentery. Su Gong stated it reduces edema; however, edema is not treated by astringent herbs, so Su Gong's statement is erroneous. He further claimed it is toxic, which clarifies previous errors. Decocting in water is the best method for treating dysentery. Rihua Zi states: Fengpi stops Huoluan (cholera-like syndrome), Cifeng (thorn-wind), and Lengfeng (cold-wind). A decoction for bathing treats these conditions.
The *Tujing* states: Fengxiang Zhi was not recorded in older texts regarding its specific origin commanderies, stating only that it grows in large mountains everywhere. Currently, it is abundant in the South and Guan-Shaan regions. It resembles white poplar and is very tall and robust. Leaves are round and forked, some triangular and fragrant. White flowers appear in February, followed by fruits attached to the branches, as large as duck eggs. They ripen in August or September and can be dried for burning. The *Nanfang Caomu Zhuang* states: Feng fruits are found only in Jiuzhen. Using them has miraculous effects; it is a rare item. Its resin is called Baijiaoxiang. Pits are cut in May, and collected in November. The bark is astringent and stops dysentery. Decocted in water for drinking. The *Erya* refers to Feng as [missing character], saying it makes a sound when the heavenly wind blows. The *Shuowen Jiezi* states: "Fengmu has dense leaves and weak branches that sway easily." It was widely planted in Han dynasty palaces. After frost, the leaves turn red and are lovely, hence frequently praised by poets. Ren Fang's *Shuyou Ji* states: There are Fengzi ghosts in the South. Old Feng trees take human form, also called Lingfeng, which are actually burls or galls. To this day, shamans in Yue obtain these burls, carve them into images of gods and spirits, and claim they can induce spiritual phenomena. Under the entry for Chenxiang (Agarwood), Fengxiang is mentioned for treating wind-induced urticaria and itching toxins. This is similar and refers to the same substance.
Jianyao Jizhong formula: For continuous hematemesis. Baijiaoxiang, regardless of quantity, is finely ground into powder. Take 2 qian each time, mixed with fresh cold water. Tao Hongjing states: Fungi growing on Feng trees cause uncontrollable laughter if eaten; antidote with Di Jiang (earth slurry). *Tongdian: Nanman Ji*: Feng resin transforms into amber. Where it lies on the ground, no grass or trees grow nearby. Digging deep reveals it at eight or nine chi depth, as large as an oak root. After peeling, it forms thus. Initially like peach gum, it hardens upon formation. Song Qiqiu's *Huashu* states: Old Feng trees transform into feathered immortals.
*Yanyi* states: Fengxiang can be confused with Songzhi (Pine resin) and used to adulterate Ru Xiang (Frankincense); distinction is particularly important. Fengxiang is pale yellow-white; burning it helps verify authenticity. It also treats wind-induced urticaria and itching toxins. Decoct in water and wash the affected area while hot.
