(Song Dynasty *Kaibao Bencao*)

[Names] Houjiang (Monkey Ginger, from *Ri Hua Zi Bencao Shiyi*), Husun Jiang (Hu Sun Ginger, Li Shizhen's note), Shimao Jiang (Stone Hair Ginger, Su Song), Shi Anqi (Stone Anthurius).
Zang Qi said: Gusuibu was originally named Houjiang. Emperor Xuanzong of the Kaiyuan era bestowed this name because it treats traumatic injuries and repairs broken bones. Some write it as "Guisuibù," which is an error. People in Jiangxi call it Husun Jiang, imitating its shape resembling a monkey.
Li Shizhen said: Anqi (Anqi) treats fractures and blood stasis. This herb has the same efficacy, hence the name Anqi.

[Collection and Explanation] Li Zhong said: Gusuibu grows in the Jiangnan region. Its rhizomes attach to trees and rocks and are covered with hairs. The leaves resemble those of Anqi.
Zang Qi said: It also grows in Qianzhou and Jizhou in Lingnan. The leaves resemble those of Shiwei but have a single stem, with other leaves growing on wood.
Daming said: It is a parasitic herb growing on trees; the rhizome resembles ginger and is slender.
Su Song said: It is now found in various prefectures along the Huai River, Zhejiang, Shaanxi, and Kuilu. It grows on trees or rocks. It is mostly found in shady places, with roots extending into strips, attached with yellow-red hairs and short leaves. It also produces large leaves forming branches. The leaf surface is green with yellow-green spots; the underside is pale green-white with purple-red spots. Leaves emerge in spring and turn dry yellow in winter. It has no flowers or fruits. The roots are harvested for medicinal use.
Kou Zongshi said: This seedling does not resemble ginger, nor does it resemble Anqi. On both sides of each large leaf, small leaves are arranged alternately, facing each other pairwise. The leaves are long with pointed lobes.
Li Shizhen said: Its rhizome is flat and long, somewhat resembling ginger. Its leaves have forked notches, quite similar to those of Guanzhong. To say the leaves resemble Anqi is greatly mistaken; to say they resemble Shiwei is also inaccurate.

Rhizome

[Processing] Lei Xiao said: Upon harvesting, scrape off the yellow-red hairs with a copper knife, cut finely, mix with honey to moisten, steam in a steamer for one day, then sun-dry for use. For urgent use, simply bake until dry; steaming is optional.

[Flavor and Properties] Bitter, warm, non-toxic. Daming said: Neutral.

[Indications] Breaks blood stasis and stops bleeding; treats fractures and traumatic injuries (*Kaibao Bencao*). Treats toxic qi invading the bones, wind-blood pain, five exhaustions and six extremes, inability to move hands and feet, upper heat and lower cold (Quan). Treats malignant sores, corrodes rotten flesh, and kills parasites (Daming). Grind into powder, sandwich between pig kidneys, roast, and eat on an empty stomach to treat tinnitus, chronic diarrhea due to kidney deficiency, and toothache (Li Shizhen).

[Elucidation] Su Song said: Gusuibu is used in formulas regulating women's blood and qi. In Shu, people treat sprains and bone/tendon injuries by crushing the root, sifting it, mixing it with millet porridge, and applying the paste to the injured area, which is effective.
Li Shizhen said: Gusuibu is a herb of the Foot-Shaoyin Kidney meridian. Therefore, it enters the bones, treats dental issues, and chronic dysentery. Previously, the son of a Wei Prefect suffered from chronic diarrhea that all physicians failed to cure, and his condition became critical. I used this herb powder stuffed into pig kidneys, roasted and fed to him, which stopped the diarrhea immediately. Since the Kidney governs urination and defecation, chronic diarrhea belongs to Kidney deficiency and cannot be treated solely through the Spleen and Stomach. *Lei Gong Pao Zhi Lun* uses this formula for tinnitus; the ear is also the orifice of the Kidney. Note: Dai Yuanli's *Zhengzhi Yaojue* states: After dysentery, if there is deficiency below and improper care, or excessive travel, sexual indulgence, or external pathogenic invasion, leading to flaccidity or pain/numbness in both legs, resulting in "Dysentery Wind" (Li Feng), one should use Duhuo Jisheng Tang taken with Hubu Sijin Wan, adding one-third part Gusuibu, grinding them together to extract juice, and taking it with wine. Externally, decoct Du Zhong, Niuxi, Shanmu Jie, Bixie, Baizhi, and Tian Nanxing, and frequently fumigate and wash the affected area. This treatment is also based on treating Kidney deficiency and bone flaccidity.

[Attached Formulas] Two old formulas, three new formulas.
Deficient Qi Attacking Teeth: Toothache with bleeding, or itching/pain. Take 2 liang of Gusuibu, finely chopped with a copper knife, stir-fried in a clay pot over low heat until black, and ground into powder. Use like regular toothpaste to brush teeth, spit out after a while, or swallow. Liu Songshi said: This method comes from *Lingyuan Fang*. It not only treats toothache but strongly strengthens bones and teeth, benefits essence and marrow, and removes toxic qi pain in bones. For loose teeth about to fall out, frequent application stabilizes them immediately, preventing further loosening. Long-term use is miraculous.
Wind-Worm Toothache: Equal parts Gusuibu and Ruxiang (Frankincense), ground into powder, made into pills with paste, and inserted into the cavity. Named Jinzhen Wan (Golden Needle Pill) (*Shengji Zonglu*).
Tinnitus and Ear Blockage: Cut Gusuibu into thin strips, fire-process, and insert into the ear while hot (Su Shi's *Tujing*).
Hair Loss After Illness: Decoct Husun Jiang (Gusuibu) and wild rose tender branches, apply the juice to the scalp.
Intestinal Wind with Blood Loss: 5 qian of Husun Jiang (charred to retain properties), taken with wine or rice water (*Ren Cun Fang*).
