*Pyrrosiae Folium* (Shiwei), grows on rocks in the valleys of Mount Hua. It is now found in Jinzhou, Jiangzhou, Chuzhou, Haizhou, Fuzhou, and Jiangning Prefecture. It grows in clusters on rocks; the leaves are like willow leaves, with hairs on the back and spots resembling leather texture, hence its name. The best quality comes from places where no water sound can be heard. Leaves are harvested in February and July and dried in the shade for use. Southern TCM practitioners stir-fry it into powder, mix it with cold wine, and administer it orally; it is very effective in treating *Fabei* (a carbuncle/abscess occurring on the back). *Pyrrosiae Folium* is also known as *Shipi*. However, there is a plant in Fuzhou also called *Shipi*, which flowers in March. Its leaves are harvested in that month to decoct a bath soup, primarily used to treat wind pathogens. Another variety grows on old tiled roofs, named *Weiwei* (Lepisorus thunbergianus), which is also good for treating *Lin* syndrome (dysuria or painful urinary frequency).

*Weiwei* is documented under the entry for *Shiwei*.

*Cibotii Rhizoma* (Gouji), grows in the valleys of Mount Chang. It is now also produced in the Taihang Mountains, Zizhou, Wenzhou, and Meizhou. The rhizome is black, three to four cun long, and about two fingers wide in diameter. The sprouts are fine and fragmented, greenish, reaching a height of about one chi, without flowers. The stems and leaves resemble those of *Guanzhong* (Cyrtomium fortunei) but are finer. The rhizome is long and highly branched, resembling the spine of a dog, hence its name. The flesh inside is greenish-yellow. Roots are harvested in spring and autumn and sun-dried for use. Currently, varieties with golden hairs are also used in prescriptions.

*Dioscoreae Hypoglaucae Rhizoma* (Bixie), grows in the valleys of Zhending. It is now found in Heyang, Shanzhou, Jingdong Circuit, Jingzhou, and various commanderies in Shu. The rhizome is yellowish-white, with many nodes, about three fingers wide in diameter. The sprouts and leaves are all green, growing as vines. The leaves are trifoliate, resembling *Shanyu* (Dioscorea opposita) or similar to mung bean leaves. Flowers come in yellow, red, and white varieties; some do not flower but bear white seeds. Roots are harvested in spring and autumn and sun-dried. Old texts state there are two types of this herb: those with thorny stems have solid, white roots; those without thorns have hollow, soft roots, with the soft ones considered superior. However, the variety produced in Chengde Jun currently has roots as hard as *Shanyu*, with vining stems and leaves resembling buckwheat leaves, and triangular seeds. The roots are harvested at any time, sliced thinly with a sharp knife, and sun-dried for use. The *Zhengyuan Guangli Fang* records its use for treating men with *Yaojiao Bi huan ji* (numbness, weakness, and stiffness in the waist and legs, leading to unsteady gait). Take 24 parts of *Dioscoreae Hypoglaucae Rhizoma* combined with 8 parts of *Eucommiae Cortex* (Duzhong), pound and sieve them. Administer orally with warm wine every morning, starting with a dose of three *qianbi*, increasing up to five *qianbi*. Beef consumption is prohibited. There is also a large prescription formula called *Bixie Wan*, which has similar efficacy.
