又名岑皮，又名石檀。产于庐江的川谷及冤句地区。二月和八月采集树皮，阴干。（大戟为其使药，畏吴茱萸。）
陶隐居说：民间称为樊皮（音同“规”），用水浸泡后用来和墨写字，颜色不脱落，呈微青色。而且树皮也很薄，恐怕不是这种。民间方剂中：只用于治疗眼疾，道家也有使用的地方。《唐本草》注解说：这种树像檀香树，叶子细小，树皮有白点但不粗糙交错，取树皮用水浸泡便呈现碧绿色，写在纸上看起来都是青色的就是真品。民间因为味道苦，称之为苦树。也用树皮治疗眼疾，有效。因为叶子像檀树叶，所以名叫石檀。臣禹锡等人谨按《药性论》记载：秦白皮，性平。畏苦瓠、防葵。主治明目，去除肝脏中的久热，两眼红肿疼痛，迎风流泪不止。治疗小儿身体发热，煎汤洗澡可痊愈。树皮一升，用水煎煮澄清，冷却后清洗红眼极有效。日华子说：清洗肝脏，益精明目，治疗小儿热惊，皮肤风痹，退热。又名盆桂。
《图经》说：秦皮，产于庐江的川谷及冤句，现在陕西各州郡及河阳也有生长。它的树木大都像檀香树。枝干都是青绿色的。叶子像匙头那么大且不光滑。没有花和果实，根像槐树的根。二月和八月采集树皮，阴干。其树皮有白点但不粗糙交错，民间称为自木。取树皮浸泡水便呈碧绿色，写在纸上看起来是青色，这才是真品。
《外台秘要》：治疗红眼及眼球上的疮疡。秦皮一两，清水一升，在白碗中浸泡，春夏季节一个饭时以上，看到碧色渗出，就用筷子头裹着棉絮，仰卧滴入患眼，仍先从眼角大眦开始让药液充满眼睛，微痛不要怕，过很久，大约吃三顿饭的功夫，就侧卧沥去热汁。每天十次以上用药，不超过两天痊愈。又一方：治疗眼睛因红眼痊愈后留下的翳晕。秦皮一两，切碎，水一升五合，煮取七合，澄清。用此液浸泡眼中。《淮南子》：某木色青，翳而羸痛蜗脘，这些都是治疗眼疾的药物。注：某，即苦历木。用水浸泡树皮变青后用来洗眼，有效。沈存中记载秦皮治疗天蛇毒。类似癞病但不是癞病。天蛇，即……
Qinpi (Cortex Fraxini)
Bitter, slightly cold or very cold, non-toxic. Primarily treats wind-cold-damp bi syndrome (a condition characterized by pain, numbness, and limited mobility of limbs and joints caused by invasion of wind, cold, and damp pathogens), eliminates the sensation of biting cold on the body surface, clears heat, treats green nebula and white membrane in the eyes (corneal opacity or clouding), cures leukorrhea in men and women, pediatric epilepsy, and fever. It can be prepared as an eye-washing decoction. Long-term consumption prevents graying of hair, lightens the body, makes the skin lustrous and smooth, promotes a robust physique, and facilitates fertility.
Also known as Cenpi (Cen Bark) and Shitan (Stone Sandalwood). Grows in the valleys of Lujiang and Yuanju. The bark is harvested in February and August and dried in the shade. (Daji [Radix Euphorbiae] serves as its guiding herb; it is incompatible with Wuzhuyu [Fructus Evodiae].)
Tao Hongjing states: Commonly called Fanpi (pronounced "gui"), when soaked in water and used to mix ink for writing, the color does not fade and appears slightly green. Moreover, the bark is quite thin, which casts doubt on this identification. In folk prescriptions: it is used solely for treating eye diseases, and also has applications in Daoist practices. The commentary in *Tang Bencao* notes: This tree resembles sandalwood, with fine leaves and bark marked with white spots but not rough or crisscrossed. When the bark is soaked in water, it yields a jade-green color; if written on paper, it appears cyan. This is the authentic variety. Because of its bitter taste, the common people call it Kushu (Bitter Tree). Its bark is also used to treat eye conditions and is effective. Since the leaves resemble those of sandalwood, it is named Shitan. Ministers Yuxi and others, according to *Yaoxing Lun*, record: Qinbaipi (White Bark of Qin), neutral in nature. Incompatible with Kuho (Bitter Gourd) and Fangkui (Radix Adenophorae). It brightens the eyes, removes long-standing heat from the liver, treats redness, swelling, and pain in both eyes, and stops profuse tearing due to wind. For pediatric fever, a bath using the decoction is curative. One sheng of bark, boiled in water until clear, cooled, and used to wash red eyes is extremely effective. Rihua Zi states: Cleanses the liver, benefits essence, brightens the eyes, treats pediatric heat-induced convulsions, cutaneous wind-bi, and reduces fever. Also known as Pengui.
*Tujing* records: Qinpi grows in the valleys of Lujiang and Yuanju; it is now also found in various prefectures of Shaanxi and Heyang. The trees generally resemble sandalwood. Branches and trunks are all greenish-blue. Leaves are about the size of a spoon head and not glossy. There are no flowers or fruits; the roots resemble those of the locust tree. The bark is harvested in February and August and dried in the shade. The bark has white spots but is not rough or crisscrossed; commonly called Zimu. Soaking the bark in water yields a jade-green color, and writing on paper shows a cyan hue, indicating authenticity.
*Waitai Miyao*: Treats red eyes and sores on the eyeball. One liang of Qinpi, soaked in one sheng of clear water in a white bowl for more than one meal-time during spring and summer, until a jade-green color emerges. Use a chopstick wrapped with cotton to apply drops into the affected eye while lying supine. Start from the inner canthus, allowing the liquid to fill the eye completely. Mild pain is acceptable. After a considerable time, approximately equivalent to three meals, tilt the head to drain the hot fluid. Apply more than ten times daily; recovery occurs within two days. Another prescription: Treats nebula and halos remaining after the resolution of red eyes. One liang of Qinpi, sliced, boiled in one sheng and five he of water until reduced to seven he, then clarified. Used to soak the eyes. *Huainanzi*: Certain trees with green color, causing nebula, wasting, pain, and curvature, are all remedies for eye diseases. Commentary: "Certain tree" refers to Kuli Mu (Bitter Traveler's Tree). Soaking the bark in water turns it blue/green for washing eyes, which is effective. Shen Cunzhong records that Qinpi treats Tianshe du (Heavenly Snake Poison). It resembles leprosy but is not leprosy. Heavenly Snake, i.e., ...
