秦亭位于陇西，宕昌也有出产。据说只有几亩地生长，因为蝮蛇吃它的根，所以很珍贵难得。也有人使用泰山产的，现在多用汉中及建平出产的。传说它与防葵同根同类，但放入水中下沉的是野狼毒，上浮的是防葵。世医使用较少，也难得，是治疗腹内疾病的要药。（《大观本草》卷十一，《政和证类本草》二六八页）
[Salvia Miltiorrhiza / Mouse Tail Sage]
Bitter in taste, slightly cold in nature, non-toxic. It primarily treats scrofula (tuberculous lymphadenitis of the neck) characterized by alternating chills and fever, and dysentery with continuous pus and blood discharge. The white-flowered variety treats white dysentery, while the red-flowered variety treats red dysentery. Also known as Lingqiao. Grows in plains and marshes. Leaves are harvested in April, flowers in July, and dried in the shade. It is abundant in fields; people harvest it to dye soap. It is also used to treat lower jiao damp-heat dysentery; it should be decocted strongly to extract the juice and formed into pills for administration. Nowadays, people also use it as a tea infusion. (Da Guan Ben Cao, Vol. 11; Zheng He Zheng Lei Ben Cao, p. 273)
[Roof Moss]
Sweet in taste, cold in nature. It primarily treats floating heat on the skin, alternating chills and fever, and promotes the qi mechanism of the small intestine and bladder. It grows on the shaded roofs of houses. Harvested in August and September. This refers to the green moss growing on tile roofs; it is peeled off and boiled for consumption. (Da Guan Ben Cao, Vol. 11; Zheng He Zheng Lei Ben Cao, p. 284)
[Ipsom Seed / Morning Glory Seed]
Bitter in taste, cold in nature, toxic. It directs qi downward, treats edema and swelling of the legs, expels wind toxicity, and promotes urination. It is a vine plant; its flowers resemble those of the broad bean and are yellow. Its fruits are small pods containing black seeds shaped like spherical kernels. Recently, this herb has been used to treat leg swelling and shortness of breath; once urination becomes smooth, recovery is invariably achieved. This herb was originally named because field people exchanged it using "pulling oxen" (referring to the seed's shape or method of exchange). There is another grass species with three white spots on its leaves... (Text ends here)
[Northern Cynanchum / Wild Wolf Poison]
Pungent in taste, neutral in nature, highly toxic. It primarily treats cough with rebellious qi, breaks up food stagnation and accumulations, treats cold-hot water retention, hypochondriac masses and癖块 (fixed lumps), malignant sores, scrofula, ulcerative lesions, evil spirits, gu poison, and can kill flying birds and running beasts. Also known as Xu Du. Grows in the valleys of Qinting and Fenggao. Roots are harvested in February and August, dried in the shade. Old roots that sink in water are considered superior. (Soybean acts as its guiding drug; it is incompatible with Polygoni Multiflori Caulis / Maijujiang.)
Qinting is located in Longxi, and Dangchang also produces it. It is said that only a few mu of land produce it, and because vipers eat its roots, it is rare and precious. Some use specimens from Mount Tai; currently, those from Hanzhong and Jianping are preferred. It is claimed to share the same root class with Fangkui (Astragali Complanati Radix); when placed in water, those that sink are Wild Wolf Poison, while those that float are Fangkui. It is rarely used by physicians today and is hard to obtain, yet it is an essential medicine for treating internal abdominal diseases. (Da Guan Ben Cao, Vol. 11; Zheng He Zheng Lei Ben Cao, p. 268)
