Funiuhua (Celastrus orbiculatus Flower)
Bitter, sweet; neutral in nature. Non-toxic. Also known as Gehuci Ci Hua (Tiger-Barrier Thorn Flower), it grows only in the counties near Yizhou in Shu. It is found near rivers and marshes, with deep red stems and many thorns. The leaves are green and fine, resembling cypress leaves but not pointed; the flowers are pale yellow, like apricot blossoms but in spikes. Harvested after mid-March and dried in the shade. It mainly treats widespread pain caused by severe wind pathogens, and cures limb contracture due to damp-bi syndrome. It can stop bleeding from the five types of hemorrhoids, and dispel dizziness and headache caused by wind.

Nanteng (Dingongteng / Caulis Duriozanthi)
Pungent, warm in nature. Non-toxic. Originates from Quanzhou and Rongzhou (both in Fujian Province), growing in the valleys of southern mountains. It often climbs on Nanmu trees, hence its name. The leaves are slightly pointed like apricot leaves, and the shoots resemble horse-whip plant without nodes.
The bark is purple-brown, and it can be harvested at any time. It specifically treats wind-pain, taken after soaking in wine. Its potency is strong, so it can also be applied externally or swallowed, turning white hair black. Shinanteng grows on rocky mountains, with tall plants that do not shed leaves in winter. The leaves resemble loquat leaves but lack hairs on the back. The flowers resemble those of the Chinese toon tree, small and clustered. Red fruits form in autumn, harvested as needed.
There are many varieties, one called Guimu. It is incompatible with Daxiao Ji (Cirsium japonicum and Cirsium setosum) and interacts with Wujia Pi (Acanthopanacis Cortex). It is most suitable for treating kidney deficiency with weak legs, and effective for wind-damp bi syndrome. Women should not take it for a long time, as doing so may cause intense longing for men. The fruit is particularly effective against insect toxins and also expels wind-bi and accumulations.

Manjingzi (Fructus Viticis)
Bitter, pungent, sweet; warm, slightly cold in nature. Yin within Yang. Non-toxic. Not restricted to specific regions, it thrives near water shores. The fruit grows on vines, named accordingly. It is as large as a paulownia seed, black in color, light, and hollow. Harvested according to season and dried in the shade; used only after stir-frying, grinding, and removing the husk. It is a herb for the Taiyang channel, incompatible with Aconitum carmichaelii (Wutou) and Gypsum Fibrosum (Shigao). It mainly treats cold and heat in muscles and bones, and contracture due to damp-bi; it regulates headaches in this channel, including heavy and dizzy sensations. It benefits joints, promotes hair growth, clears the nine orifices, expels parasites, disperses wind pathogens, and brightens the eyes. It stops tinnitus and strengthens loose teeth. Long-term use delays aging, lightens the body, and makes the skin lustrous and oily (pronounced "zhi"). Contraindicated in cases of stomach deficiency, as it may cause adverse effects.
