The *Lu Yan Fang* (Verified Records Formulas) treats arrows penetrating the abdomen and rupturing the intestines, causing blood accumulation, with the *Kuizi Tang* (Hibiscus Seed Decoction):
Take one *sheng* of *Kuizi* (Abelmoschi Fructus, Hibiscus seed), four *sheng* of urine, boil until one *sheng* remains, and take it all at once to expel the foreign body; the condition will then heal.

It is also stated: To treat internal bleeding from arrow wounds and abdominal distension due to blood stasis, use the *Guazi San* (Melon Seed Powder):
*Dried Ginger* (Ganjiang, Rhizoma Zingiberis Preparatum) (two *liang*)
*Melon Seeds* (Guazi, Cucurbitae Semen) (two *liang*)
Grind these two ingredients and sieve them. Take one *fangcun bi* (a measure equivalent to a square inch scoop) with wine before meals.

Another formula: *Luru San* (Rubia Powder):
*Luru* (Radix Rubiae, Madder root) (three *liang*)
*Almond* (Xingren, Armeniacae Semen Amarum) (two *liang*)
Grind these two ingredients. Take one *fangcun bi* with wine before meals.

The *Bing Yuan Lun* (Treatise on the Origins and Manifestations of Diseases) states: If an arrow penetrates the bone and shatters it, the arrowhead must be extracted, and all broken bone fragments must be removed before applying medicine. Otherwise, the wound will never heal; even if it does, it will remain painful. If further touched or injured, it may cause panic, boiling blood, and ulceration, potentially leading to death.

The *Ge Shi Fang* (Ge’s Formulas) treats arrowheads and various blade edges stuck in hidden areas such as the throat, pharynx, chest, and diaphragm that cannot be removed:
Crush *Almonds* (Xingren, Armeniacae Semen Amarum) and apply topically.

Another formula: Apply the brain of the *Mole Cricket* (Lougu, Gryllotalpae Ganglion) topically.

The *Qian Jin Fang* (Essential Prescriptions Worth a Thousand Gold) treats metal arrowheads that cannot be removed:
*Bai Lian* (Bai Lian, Ampelopsis Radix) and *Ban Xia* (Pinelliae Rhizoma) in equal parts, ground into powder. Take one *fangcun bi* with wine, three times daily. [Note: The *Lu Yan Fang* records: *Bai Lian* three *liang*, *Ban Xia* (dried) three *liang*. Roast, sieve, and take one *fangcun bi* with water, three times daily. Superficial wounds expel the object in ten days, deep wounds in twenty days, ensuring it never remains lodged in the flesh.]

The *Duan Ju Fang* (Short Drama Formulas) treats metal arrowheads stuck in the throat, pharynx, chest, back, diaphragm, and other locations that cannot be removed:
*Peony Root Bark* (Mudan Pi, Moutan Cortex) (one *fen*)
*Bai Lian* (Ampelopsis Radix) (one *fen*)
Grind into powder, take one *fangcun bi* with wine, three times daily. The object will emerge spontaneously. [Note: In the *Qian Jin Fang*, the dosage of *Bai Lian* is two *fen*.]

Another formula: Take used menstrual cloth from a woman, burn it to ash, take one *fangcun bi* with wine, three times daily; the object will be expelled immediately. (This matches the *Ji Yan Fang*.)

The *Lu Yan Fang* treats arrowheads stuck in the abdomen with the *Qumai San* (Cheatgrass Powder):
Grind *Qumai* (Herba Siegesbeckiae) finely. Take one *fangcun bi* with wine, three times daily and twice at night. It can also treat various splinters. It may also be mixed with wine for topical application.

It is also stated: For an arrow that has remained in the body for three to five years without being expelled:
Take three *sheng* of *Hemp Seeds* (Mazi, Cannabis Fructus), grind into powder, mix with water to obtain three *sheng* of juice, and take warm; it will be expelled shortly.

The *Long Men Fang* (Dragon Gate Formulas) treats arrowheads stuck in the abdomen:
Crush *Trichosanthes Fruit* (Gualou, Trichosanthis Fructus) and apply to the wound. Do this three times daily; the object will emerge spontaneously.
