(From *Bencao Shiyi* [Supplement to Materia Medica])
[Names] Guizhen (Ghost Needle).
Chen Zangqi stated: This refers to the part of the "rotten bamboo root" that first enters the soil. Because its nature is considered malicious and evil, its original name was concealed. There is also a herb named "Guizhen" in the Grass category.
[Properties and Flavor] Bitter, neutral, non-toxic.
[Indications] Treats sudden onset of malignant qi, adverse invasion (sudden fright or pathogenic invasion), and pain in the heart and abdomen; decocted juice is taken orally (Chen Zangqi). Decocted juice is taken to expel fish bones stuck in the throat. Calcined until carbonized but retaining its properties, mixed with a small amount of Calomelas (Qingfen), and applied with oil to treat head sores in children (Li Shizhen).
[Prescriptions] Two new prescriptions included.
Fish bone stuck in the throat: Take rotten bamboo from the base of a fence, remove mud, grind into powder, and make pills the size of an Indian corn seed using honey. Wrap in cotton and hold in the mouth; the bone will dissolve naturally. (Wang Kuang, *Baiyi Xuanfang* [Selected Prescriptions for Hundred Diseases])
Hematuria (blood in urine): Take bamboo roots under fences that have been in the soil for many years, quantity unspecified. Wash clean, decoct in water, and drink several bowls; bleeding stops immediately. (*Jiuji Liangfang* [Good Prescriptions for Emergencies]...)
(Seven species in the Miscellaneous Wood Category, nineteen species appended)
(From *Shennong Bencao Jing* [Divine Farmer's Materia Medica], Lower Grade)
[Correction] Merged with "Chengli Chizhu" [Red Pillar Inside the City] listed as "Known Name, Unused" in *Mingyi Bielu* [Record of Famous Physicians].
[Names] Baishui Chengzhongmu (Century-Old Tree Within the City Walls) (*Shennong Bencao Jing*), Chengli Chizhu [Red Pillar Inside the City].
*Mingyi Bielu* states: Huaimu grows in Pingze, Jinyang. It also states: Chengli Chizhu grows in Pingyang during the Jin Dynasty.
Li Shizhen stated: According to *Wu Pu Bencao*: Huaimu grows in Pingyang, Jin Dynasty, and Pingze, Hedong. This matches the origin and indications of "Chengli Chizhu" in *Mingyi Bielu*, indicating they are the same substance. It refers to wood from ancient cities used by people of the Jin Dynasty, hence the statement that it grows in Pingyang, Jin, and Hedong. Now merged into one entry; however, the term "Huaimu" may contain an error.
[Properties and Flavor] Bitter, neutral, non-toxic. *Mingyi Bielu* states: Pungent.
Wu Pu stated: Shen Nong and Lei Gong considered it: Non-toxic.
[Indications] Treats chronic cough with rebellious qi, damage to the Middle Jiao resulting in emaciation and weakness. For women, treats erosion of the yin, leukorrhea with bleeding, excessive white discharge with yin erosion, wind-damp bi syndrome with pathogenic qi, and tonifies the Middle Jiao and benefits Qi (all from *Mingyi Bielu*). Decoction is taken to treat difficult labor...
("Known Name, Unused" in *Mingyi Bielu*)
[Correction] Merged with two entries from *Bencao Shiyi* [Supplement to Materia Medica]: "Fumu" [Rotten Wood] and "Dizhu" [Earth Lord].
[Names] Dizhu [Earth Lord].
Chen Zangqi stated: "Chengdong Fumu" [Rotten Wood East of the City] refers to ancient trees east of the city that have rotted in the soil, also known as Dizhu. "East of the City" carries the same meaning as "soil of the east wall."
The prescription of Du Zhenglun: Uses wood from ancient city pillars decocted in water and taken orally to treat dystocia [difficult labor]. It belongs to this category.
[Properties and Flavor] Salty, warm, non-toxic. Chen Zangqi stated: Neutral.
[Indications] Pain in the heart and abdomen, stops diarrhea and bloody/purulent stools (*Mingyi Bielu*). Treats ghostly qi.
Soak rotten wood in water and apply the juice to the affected area; alternatively, grind into powder and mix with vinegar for application (Chen Zangqi). For any cases of spasmodic pain in the hands and feet, numbness, and inability to move, decoct rotten wood in water and apply the hot liquid to the painful area; this is very effective (Li Shizhen).
