\r杜仲\ph310.bmp\r，生上虞山谷及上党、汉中。今出商州、成州、峡州近处大山中
亦有之。木高数丈，叶
如辛夷，亦类柘；其皮类浓朴，折之内有白丝相连。二月、五月、六月、九月采皮用。江南
人谓之 。初生叶嫩时，采食，主风毒香港脚，及久积风冷、肠痔、下血。亦宜干末作汤，谓
之芽。花、实苦涩，亦堪入药。木作屐，亦主益脚。箧中方主腰痛补肾汤，杜仲一大斤，
五味子半大升，二物细切，分十四剂，每夜取一剂，以水一大升，浸至五更，煎三分减一，
滤取汁；以羊肾三、四枚，切，下之，再煮三、五沸，如作羹法，空腹顿服。用盐酢和之，
亦得，此亦见崔元亮《海上方》。但崔方不用五味子耳。
\r枫香\ph311.bmp\r脂，旧不载所出州郡，云所在大山皆有，今南方及关陕多有之。
似白杨，甚高硕；叶圆
而作岐，有三角而香；二月有花，白色；乃连着实，大如鸭卵。八月、九月熟，曝干可烧
。《南方草木状》曰∶枫实惟九真有之。用之有神，乃难得之物。其脂为白胶香，五月斫为
坎，十一月采之。其皮性涩，止水痢，水煎饮之。《尔雅》谓枫为 ，言天风则鸣 也
。《说文解字》云∶枫木，浓叶弱枝善摇。汉宫殿中多植之，至霜后叶丹可爱，故骚人多称
之。任 《述异记》曰∶南中有枫子鬼。枫木之老者为人形，亦呼为灵枫，盖瘤瘿也。至今
越巫有得之者，以雕刻鬼神，可致灵异。下沉香条，有枫香，云疗风瘾疹痒毒，与此相类，
即一物也。

杜仲，生长在上虞的山谷以及上党、汉中地区。现在出产于商州、成州、峡州附近的大山中也有。树木高达数丈，叶子像辛夷，也类似柘树；它的树皮类似厚朴，折断后内部有白色丝状物相连。二月、五月、六月、九月采集树皮使用。江南人称之为“思仙”。初生嫩叶时，采摘食用，主治风毒引起的香港脚（足部肿痛），以及久积的风冷、肠痔、便血。也可以晒干磨粉煮汤饮用，称为“芽”。花和果实味道苦涩，也可以入药。木材用来制作木屐，也有助于强健双脚。《箧中方》中记载的主治腰痛补肾汤：杜仲一大斤，五味子半大升，将这两味药细切，分成十四剂，每晚取一剂，用水一大升，浸泡至五更天，煎煮至剩余三分之一，过滤取汁；用羊肾三到四枚，切片放入药汁中，再煮沸三到五次，做法如同煮羹，空腹一次性服用。可以用盐和醋调和食用，也可以，这也见于崔元亮的《海上方》。只是崔方的方子不用五味子罢了。
枫香脂，旧籍未记载其出产的州郡，说所在的大山都有，现在南方及关陕地区多有出产。形状像白杨，非常高大硕壮；叶子圆形且分叉，呈三角形且有香气；二月开花，白色；花朵连着果实，大小如鸭蛋。八月、九月成熟，晒干后可以燃烧。《南方草木状》说：枫实只有九真郡才有。使用它很有神效，是难得之物。它的树脂称为白胶香，五月砍开树干形成凹槽，十一月采集。它的树皮性质涩，能止住水泻，用水煎煮饮用。《尔雅》称枫为“檕”，意思是天风吹过时它会鸣响。《说文解字》说：枫木，叶子浓密枝条柔弱善于摇动。汉代的宫殿中多种植它，到了霜降后叶子变红可爱，所以诗人多称颂它。任昉的《述异记》说：南方有枫子鬼。古老的枫木化为人的形状，也称为灵枫，大概是树瘤瘿节。至今越地的巫师如果有得到它的，用来雕刻鬼神，可以招致灵异。在下沉香条目下，有枫香，说治疗风瘾疹瘙痒毒素，与此相似，就是同一物。

Eucommia ulmoides (Du Zhong), grows in the valleys of Shangyu, as well as in Shangdang and Hanzhong. It is also found in the large mountains near Shangzhou, Chengzhou, and Xiazhou. The tree reaches several zhang in height; its leaves resemble those of Magnolia biondii (Xin Yi) and are similar to those of Broussonetia papyrifera (Zhe); its bark resembles that of Phellodendron amurense (Nong Po), and when broken, white fibrous strands connect the interior. The bark is harvested for use in February, May, June, and September. In Jiangnan, it is called "Si Xian". When the young leaves first sprout, they are picked and eaten; they treat Feng Du Hong Jiao (wind-toxity causing podagra/swollen feet), as well as long-standing accumulation of wind-cold, intestinal hemorrhoids, and bloody stool. They can also be dried, powdered, and decocted into a soup, known as "Ya". The flowers and fruits are bitter and astringent but are also suitable for medicinal use. The wood is used to make clogs, which also help strengthen the feet. The formula from *Qie Zhong Fang* for treating lower back pain and tonifying the kidneys: 1 jin of Eucommia ulmoides (Du Zhong) and half a large sheng of Schisandra chinensis (Wu Wei Zi). These two herbs are finely cut and divided into fourteen doses. Each night, take one dose, soak it in one sheng of water until the fifth watch (early morning), decoct until reduced by one-third, filter to obtain the juice; add three or four sheep kidneys, sliced, into the juice, boil again for three to five boils, similar to making a soup, and consume on an empty stomach in one go. It can be taken with salt and vinegar, which is also acceptable. This is also recorded in Cui Yuanliang's *Hai Shang Fang*. However, Cui's formula does not include Schisandra chinensis (Wu Wei Zi).
Resina Liquidambaris (Feng Xiang Zhi), old texts do not record the specific provinces where it originates, stating it is found in major mountains everywhere. It is now abundant in the south and Guan-Shan regions. It resembles Populus alba (Bai Yang) and is very tall and robust; the leaves are round and lobed, triangular in shape and fragrant; it flowers in February with white blossoms; the flowers persist attached to the fruit, which is as large as a duck egg. It ripens in August and September and can be sun-dried for burning. *Nanfang Caomu Zhuang* states: "Feng Shi (fruits of Liquidambar) are only found in Jiuzhen Commandery." Using it has miraculous effects and is a rare item. Its resin is called Bai Jiao Xiang (White Gum Resin); cuts are made in the bark in May, and collected in November. The bark is astringent in nature and stops watery diarrhea; it is decocted in water and drunk. *Erya* refers to Feng as "Zhi", saying it makes a sound when the heavenly wind blows. *Shuowen Jiezi* states: "Feng mu (Feng tree), with dense leaves and weak branches that sway easily." Many were planted in Han dynasty palaces; after frost, the leaves turn red and are lovely, so poets often praised them. Ren Fang's *Shu You Ji* says: "In the south, there are Feng Zi Ghosts. Ancient Feng trees transform into human shapes, also called Ling Feng, likely referring to tree galls/tumors." To this day, shamans in Yue who obtain these use them to carve deities and spirits, claiming to invoke spiritual phenomena. Under the entry for Agarwood (Chen Xiang), there is mention of Feng Xiang, stated to treat wind-induced urticaria and itching/toxicity, which is similar to this and refers to the same substance.
