Zizhi (Poria with Pine Root) serves as its Shi herb (directing herb). It is incompatible with Gansui (Euphorbia Lathyris Root). Now it is found everywhere near the capital; people in Dongshan and Nanjiang dig it up frequently to eat as a staple food. The largest and finest specimens come from Nankang, and these are also used for dietary therapy.
[Note]: When Shuyu is dried, pounded into fine powder, and sifted into starch, it is delicious and effective in curing diseases and tonifying the body. There are two types: one is white and superior; the other is greenish-black and inferior in taste. Those from the Shu Road are particularly good.

Baizhu (Atractylodes Macrocephala Rhizome), Gouqigen (Lycium Bark), and Sangbaipipi (Mulberry Root Bark) serve as its Shi herbs (directing herbs). There are two types of Ju (Chrysanthemum): one has purple stems, fragrant odor, sweet taste, and edible leaves for soup; this is the true Chrysanthemum. The other tastes bitter and is inedible, named Kuyi (Bitter Mugwort-like plant), which is not true Chrysanthemum. Their flowers look very similar, distinguished only by their sweet or bitter taste. Most abundant in Li County, Nanyang; now found everywhere, easily propagated by seed. There is also White Chrysanthemum, with similar stems and leaves but white flowers, harvested in May. It also treats wind-induced vertigo and can prevent hair whitening. The "Immortal Classics" regard Chrysanthemum as having miraculous uses, though hard to obtain in large quantities; it is suitable for regular consumption.
