[Names] Xiangdou (Elephant Bean) (from *Kaibao Bencao*).
Li Shizhen said: Its fruit resembles an elephant in shape, hence the name.
[Collection and Explanation] Chen Zangqi said: According to *Guangzhou Ji*: Tengzi grows in the forests of southern Guangzhou. It grows as a vine clinging to trees, similar to *Tongcao* vine. Its fruit takes three years to mature; the pod is like a bow case, and the seeds are as large as chicken eggs, with a purplish-black exterior. Its shell can be used to store alchemical pills without deteriorating over years. The kernels inside are used for medicinal purposes and must be roasted before use.
Li Shizhen said: The seeds are purplish-black with a slight luster, one to two cun in diameter, round and flat. People often remove the flesh to make them into medicine ladles, which are hung at their waists.
[Flavor and Properties] Astringent and sweet, neutral nature, non-toxic.
[Therapeutic Actions] Treats five types of hemorrhoids (*Wuzhi*), gu poison (*Gudu*), flying corpse pharyngitis (*Feishi Houbi*). Grind the kernel into powder, lightly roast, and take with water, one or two bi. It can also be used with soybeans for bathing the face to remove dirt (Chen Zangqi). Treats pediatric rectal prolapse, bloody dysentery, and hematochezia; burn to ash and ingest. Alternatively, take one seed, cut open the pulp, roast and grind, and take 2 qian with hot wine on an empty stomach. Within three doses, it will surely be effective (*Kaibao Bencao*). Resolves various drug toxicities (Li Shizhen, *Caomu Zhuang*).
[Attached Prescriptions] One old prescription, three new prescriptions.
Pharyngitis with swelling and pain: Burn Tengzi to carbon, grind into powder, and take 1 qian with wine (*Shenghui Fang*).
Hemorrhoids with bleeding: Burn Tengzi until the substance remains (*Cunxing*). Take 2 qian with rice water; it is effective (Kou Zongshi, *Yanyi*).
Intestinal wind with bleeding: Hua Tuo's *Zhongzang Jing*: Use two Tengzi seeds and forty-nine non-bitten soap bean (*Zaoying*) seeds. Burn until the substance remains, grind into powder. Take 2 qian each time, washed down with warm wine. After a short while, drink another cup of wine and swallow immediately; extremely effective.
*Shenghui Fang*: Use three thick Tengzi seeds, wrap them in seven layers of wet paper, bake until cooked, remove the shell, and grind the pulp into powder. Take 1 qian each time, before meals, washed down with yellow wine (*Huangjiu*), once daily.
[Appendix] Hezicao (Hezi Grass) (from *Shiyi*). Chen Zangqi said: The seeds and leaves have slight toxicity. They treat gu poison and snake bites; crush and apply to sores. It climbs along banks, has pointed leaves and white flowers, and the seed contains two halves resembling a box.
