[Juice Mandarin Orange (Ruguanzi)]
Non-toxic. Grows naturally.
Juice mandarin orange promotes the discharge of heat-toxins in the intestines and stomach, relieves sudden thirst, and promotes urination. (Recorded by Famous Physicians) [Plant Morphology] (*Bencao Tujing* states:) The tree resembles the kumquat tree, and its fruit is similar to kumquat but rounder and larger. The peel is green when unripe and yellow or reddish when ripe. It is particularly sour before the frost and very sweet after the frost, hence the name "Ganzi" (Mandarin). There are also Shagan, Qinggan, and Shangan; their properties and effects are similar, but only the peel of Shangan treats sore throat, while the others are rarely used. (*Bencao Yanyi* states:) Nowadays, juice mandarin peels are often sold as tangerine peels to people, so one must not fail to distinguish them carefully. Tangerine peel is not very bitter, whereas tangerine peel is extremely bitter, remaining bitter even when ripe. If distinguishing between tangerine and mandarin by the tightness of the peel, due to different regional preferences, both can be either tight or loose. [Origin] (*Bencao Tujing* states:) Grows in Lingnan and Jiangnan regions; those from Xirong are superior. [Season] (Growth) Leaves fall in April and regrow. (Harvest) Fruits are harvested in October.

[Sugarcane]
Non-toxic. Grows in clumps.
Sugarcane directs qi downward, harmonizes the middle, assists spleen qi, and promotes bowel movements. (Recorded by Famous Physicians) [Names] Kunlun cane, Di cane, Zhu cane. [Plant Morphology] (*Bencao Tujing* states:) There are two types here. One resembles reeds, with sparse nodes that are thin and short, called Di cane; the other resembles bamboo, being thick and long, called Zhu cane. Additionally, Guangzhou produces a type that grows for several years, resembling large bamboo, over three meters long. Now, the large ones grown in Jiangze, Min-Guang, and Sichuan are also about three meters high; people extract their juice to make sand sugar (brown sugar). (Tao Hongjing says:) Sugarcane has two types: red is named Kunlun cane, white is named Di cane. Those from Shu and Lingnan are superior and are all processed into sand sugar. Now, there is much in Jiangdong, but it is inferior to that of Shu, though still sweet and delicious. [Origin] (*Bencao Tujing* states:) Those from Jiangdong are superior; Luling also has good quality. Now, they are available in Jiangzhe, Min-Guang, and Sichuan.
