藏器曰∶俗呼为象胆，以其味苦如胆也。
【集解】 曰∶芦荟生
颂曰∶今惟广州有来者。其木生山野中，滴脂泪而成。采之不拘时月。
时珍曰∶芦荟原在草部。《药谱》及《图经》所状，皆言是木脂。而《一统志》云∶爪
哇、三佛齐诸国所出者，乃草属，状如鲎尾，采之以玉器捣成膏。与前说不同，何哉？岂亦
木质草形乎？

【校正】自草部移入此。
【释名】胡桐碱（《纲目》）、胡桐律。
曰∶胡桐泪，是胡桐树脂也，故名泪。作律字者非也，律、泪声讹尔。
时珍曰∶《西域传》云∶车师国多胡桐。颜师古注云∶胡桐似桐，不似桑，故名胡桐。
虫食其树而汁出下流者，俗名胡桐泪，言似眼泪也。其入土石成块如卤碱者，为胡桐碱（音
减）。或云∶律当作沥，非讹也，犹松脂名沥青之义。亦通。
【集解】恭曰∶胡桐泪，出肃州以西平泽及山谷中。形似黄矾而坚实。有夹烂木者，云
是胡桐树脂沦入土石碱卤地者。其树高硕，皮叶似白杨、青桐、桑辈，故名胡桐木，堪器用。
保升曰∶凉州以西有之。初生似柳，大则似桑、桐。其津下入地，与土石相染，状如姜
极咸苦，得水便消，若矾石、硝石之类。冬月采之。大明曰∶此有二般∶木律不中入药；惟
用石律，石上采之，形如小石片子，黄土色者为上。颂曰∶今西番亦有商人货之。时珍曰∶
木泪乃树脂流出者，其状如膏油。石泪乃脂入土石间者，其状成块，以其得卤
药为胜。
【气味】咸、苦，大寒，无毒。
恭曰∶伏砒石。可为金银焊药。
【主治】大毒热，心腹烦满，水和服之，取吐。牛马急黄黑汗，水研三、二两灌之，立
瘥（《唐本》）。主风虫牙齿痛，杀火毒、面毒（大明）。风疳 齿，骨槽风劳。能软一切物。
多服令人吐（
【发明】颂曰∶古方稀用。今治口齿家多用，为最要之物。
时珍曰∶石泪入地受卤气，故其性寒能除热，其味咸能入骨软坚。

【释名】奴会（出自《开宝本草》）、讷会（出自《嘉祐补注神农本草拾遗》）。
李时珍说：名称的含义尚不清楚。
苏颂（引藏器语）说：民间称为象胆，因为它的味道像胆汁一样苦。
【集解】陶弘景说：芦荟生长在……
苏颂说：现在只有广州有进贡的。这种树生长在山野中，滴下树脂泪状物而成。采集不限制月份。
李时珍说：芦荟原本在草部。《药谱》和《图经》所描述的，都说它是木脂。而《一统志》记载：爪哇、三佛齐等国出产的，属于草类，形状像鲎的尾巴，用玉器捣成膏状。这与前面的说法不同，为什么呢？难道也是木质草形吗？
【气味】味苦，性寒，无毒。
【主治】热风引起的烦闷，胸膈间的热气，明目镇心，治疗小儿癫痫惊风，治愈五疳病，杀灭三种寄生虫及痔疮疮疡，解除巴豆毒（出自《开宝本草》）。主治小儿各种疳热（李权）。研成粉末，敷于……牙齿
【发明】李时珍说：芦荟是厥阴经的药物，其功效专门在于杀虫清热。以上各种疾病，都是热与虫所致。
浸……炙……
【附方】新增一方。
小儿脾疳：芦荟、使君子等分，研成粉末。每次用米汤送服一、二钱。（出自《卫生易简方》）
（《唐本草》）
【校正】从草部移入此部分。
【释名】胡桐碱（出自《本草纲目》）、胡桐律。
陶弘景说：胡桐泪是胡桐树的树脂，所以叫泪。写作“律”字是不对的，“律”和“泪”只是声音讹误罢了。
李时珍说：《西域传》记载：车师国多胡桐树。颜师古注释说：胡桐像桐树，不像桑树，所以名叫胡桐。虫子吃它的树导致汁液流出向下流淌的，俗名叫胡桐泪，意思是像眼泪一样。那些渗入土石结成块状像卤碱的，叫做胡桐碱（音减）。有人说：“律”应当作“沥”，并不是讹误，就像松脂名叫沥青的意思一样。也通顺。
【集解】苏恭说：胡桐泪，出产在肃州以西的平泽及山谷中。形状像黄矾但质地坚实。有的夹杂着腐烂木头，说是胡桐树脂沦陷在土石碱卤之地。这种树高大硕壮，皮叶像白杨、青桐、桑树之类，所以名叫胡桐木，可供器物使用。
苏保升说：凉州以西有生长。初生时像柳树，长大则像桑树、桐树。其津液流入地下，与土石相染，形状像姜，极咸苦，遇水就溶解，像矾石、硝石之类。冬季采集。
孟诜说：这有两种：木律不适合入药；只用石律，在石头上采集，形状像小石片子，黄土色的是上品。
苏颂说：现在西番也有商人贩卖它。李时珍说：木泪是树脂流出的，形状像膏油。石泪是脂液进入土石之间的，形状结成块，因为它得到卤气，作为药材更好。
【气味】味咸、苦，性大寒，无毒。
苏恭说：能伏制砒石。可作为金银焊接药。
【主治】大毒热，心腹烦满，用水调服，使其呕吐。牛马急黄黑汗症，用水研磨二三两灌服，立即痊愈（出自《唐本草》）。主治风虫牙齿痛，杀灭火毒、面毒（孟诜）。治疗风疳导致的牙龈问题，骨槽风劳。能软化一切物体。多服让人呕吐（……）
【发明】苏颂说：古方中很少使用。现在治疗口齿科多用，是最重要的药物。
李时珍说：石泪入地受卤气影响，所以其性寒能除热，其味咸能入骨软坚。
【附方】新增六方。
湿热牙疼，喜欢吸风：胡桐泪，加入麝香掺敷。
牙疼出血：胡桐泪半两，研成粉末。每晚贴敷。或加入少许麝香。
走马牙疳：胡桐碱、黄丹等分为末，掺敷。（出自《医林集要》）
牙疳宣露，脓血臭气者：胡桐泪一两，枸杞根一升。每次用五钱，煎水热漱。另一方法：胡桐泪、葶苈等分。研末掺敷。（出自《圣惠方》）
牙齿蠹黑：这是肾虚。胡桐泪一两，丹砂半两，麝香一分，研成粉末，掺敷。（出自《圣济总录》）
[Correction] Transferred from the Herb Section to this section.
[Names] Nu Hui (from *Kaibao Bencao*), Ne Hui (from *Shiyi*).
Li Shizhen says: The meaning of the names is unknown.
Zang Jing (cited by Su Song) says: Commonly called "Elephant Gallbladder" because its taste is bitter like gallbladder bile.
[Collection and Explanation] Tao Hongjing says: Lu Hui grows in...
Su Song says: Currently, only Guangzhou has supplies. The tree grows in mountains and wilds, dripping resinous tears. Collection is not restricted by month.
Li Shizhen says: Lu Hui was originally in the Herb Section. Both *Yapu* and *Tujing* describe it as tree resin. However, *Yitongzhi* states that those produced in Java, Srivijaya, and other countries belong to the grass category, resembling a horseshoe crab's tail, and are pounded into paste using jade mortars. This differs from previous descriptions; why? Could it also be woody yet herbaceous in form?
[Flavor and Properties] Bitter, Cold, Non-toxic.
[Indications] Treats wind-heat causing vexation and oppression, heat qi in the chest and diaphragm, brightens the eyes and calms the heart spirit, treats pediatric epilepsy and convulsions, cures five types of Gi disease (malnutrition syndrome), kills three types of parasites, treats hemorrhoidal sores, and resolves Radix Codonopsis (Baidu) toxicity (*Kaibao Bencao*). Treats various heat patterns of pediatric Gi disease (Li Quan). Pounded into powder and applied to... teeth.
[Elucidation] Li Shizhen says: Lu Hui is a medicine for the Jueyin Meridian. Its efficacy specializes in killing parasites and clearing heat. All the aforementioned diseases are caused by heat and parasites.
Soaking... Roasting...
[Attached Formulas] One new formula.
Pediatric Spleen Gi Disease: Lu Hui and Crataegus pinnatifida (Shijuanzi) in equal parts, pounded into powder. Take 1–2 qian each time with rice water (*Weisheng Yijian Fang*).
(*Tang Bencao*)
[Correction] Transferred from the Herb Section to this section.
[Names] Hutong Jian (from *Bencao Gangmu*), Hutong Lü.
Tao Hongjing says: Hutong Lei is the resin of the Hutong tree, hence named "Lei" (tears). Writing it as "Lü" is incorrect; "Lü" and "Lei" are merely phonetic errors.
Li Shizhen says: *Xiyu Zhuan* records: Cheshi State has many Hutong trees. Yan Shigu annotates: Hutong resembles Paulownia but not Mulberry, hence the name Hutong. When insects eat the tree and sap flows down, it is commonly called Hutong Lei (Hutong Tears), resembling human tears. Those that penetrate soil and rocks forming lumps like halite are called Hutong Jian (pronounced jian). Some say "Lü" should be written as "Li" (drip), which is not an error, similar to how pine resin is called Qingli (black asphalt). This interpretation is also acceptable.
[Collection and Explanation] Su Gong says: Hutong Lei is produced west of Suzhou in flat marshes and valleys. It resembles Huangfan (yellow alum) but is solid. Some contain rotting wood, said to be Hutong resin submerged in saline soil. The tree is tall and robust, with bark and leaves resembling Populus alba, Firmiana simplex, or Morus alba, hence named Hutong Mu, suitable for making vessels.
Su Baosheng says: Grows west of Liangzhou. Initially looks like willow, growing large like mulberry or paulownia. Its sap enters the ground, staining soil and rocks, resembling ginger, extremely salty and bitter, dissolving in water like alum or saltpeter. Collected in winter.
Meng Shen says: There are two types: Mu Lü (wood lü) is not suitable for medicinal use; only Shi Lü (stone lü) is used. Collected from stones, shaped like small stone flakes, with yellow-earth color being the best grade.
Su Song says: Merchants from Western Fan also sell it now. Li Shizhen says: Mu Lei is flowing resin, resembling ointment. Shi Lei is resin embedded in soil and rock, forming lumps. Because it absorbs saline qi, it is superior as a medicine.
[Flavor and Properties] Salty, Bitter, Great Cold, Non-toxic.
Su Gong says: Can suppress Realgar. Can be used as solder for gold and silver.
[Indications] Treats severe toxic heat, fullness and vexation in the heart and abdomen. Mix with water and induce vomiting. For cattle and horses suffering from acute jaundice with black sweat, grind 2–3 liang in water and administer orally, resulting in immediate recovery (*Tang Bencao*). Treats wind-parasitic toothache, kills fire toxin and facial toxin (Meng Shen). Treats wind-Gi affecting gums, chronic alveolar osteitis. Can soften all hard objects. Excessive intake causes vomiting (...).
[Elucidation] Su Song says: Rarely used in ancient formulas. Now widely used in dentistry, it is a most essential substance.
Li Shizhen says: Shi Lei absorbs saline qi from the earth, so its cold nature clears heat, and its salty flavor enters the bones to soften hardness.
[Attached Formulas] Six new formulas.
Damp-heat toothache, preferring cool air: Hutong Lei mixed with Moschus (Shexiang) and applied.
Toothache with bleeding: Half liang of Hutong Lei, pounded into powder. Apply nightly. Or add a small amount of Moschus.
Rapid-progressing gingivostomatitis (Zouma Yagan): Hutong Jian and Dan Sha (Cinnabar) in equal parts, pounded into powder and applied (*Yilin Jiyao*).
Gingival recession with pus, blood, and foul odor: One liang of Hutong Lei, one sheng of Lycium chinense root (Gouqigen). Use 5 qian per dose, decoct in water and rinse hot. Another method: Hutong Lei and Thlaspi arvense (Tingli) in equal parts. Pound into powder and apply (*Shenghui Fang*).
Teeth decayed and blackened: Caused by Kidney deficiency. One liang of Hutong Lei, half liang of Cinnabar (Dansha), one fen of Moschus (Shexiang), pounded into powder and applied (*Shengji Zonglu*).
