Produced in Guangdong, the fruit is the size of a thumb, shaped like an eggplant but with ridges, hard as stone and unbreakable by striking; its calyx is yellowish-black, resembling soy sauce color. Another variety refers to the tender seeds of *Ipomoea nil* (Morning Glory), which people in Suzhou harvest and preserve in honey for food; this is also called Tianqie (Heavenly Eggplant). It has a strong qi-breaking effect and is completely different from the aforementioned Tianqie.

For treating epigastric pain: *Jiusheng Kuhai* (Sea of Life-Saving Bitterness) records: Grind it with water and take orally; one fruit per dose is effective.

For treating scorpion venom: *Wuzazu* (Miscellaneous Morsels) records: In the Guanzhong region, there is Tianqie, which can treat scorpion stings.

Produced in Qiongzhou (modern Hainan). If the fruit contains one seed, ingestion leads to immediate death; if it contains two seeds, it can be detoxified using fecal urine (*Fenqing*). This drug is used only in external surgical plasters and hemp preparations; it may only be applied externally and not taken internally.

Gao Lian in *Zhenyi Yaopin* (Precious and Rare Medicinal Materials) states: Mianqie (Burmese Eggplant), also written as Mianqie, resembles a large chestnut, covered by a cap-like structure resembling painted skin. It originates from the Burma region in southern Yunnan and is hard as stone. *Dianlue* (Brief Records of Dian/Yunnan) notes: The branches and leaves of Mianqie resemble those of cultivated eggplants; the fruits resemble lychee seeds and have a calyx. Locals carve them and hang them up; they are used to wipe the eyes to remove nebulae (cataracts/opacities) and can also resolve carbuncle toxins. *Dunnan Zaji* (Miscellaneous Records of Southern Yunnan) states: Mianqie comes from Burma, is large and purple, with a round and intact calyx; those with a waxy yellow hue are of superior quality. *Yuezhi* (Records of Yue/Guangdong) states: Muqie (Wooden Eggplant) is produced in Gaozhou Prefecture, Guangdong, featuring a square calyx; it is used to wipe the eyes to clear visual obscurations, which is indeed Mianqie. When ground with water and applied topically, it treats toothache; applied to the eye orbits, it clears fire-toxin and can detoxify various medicines.

For treating Dingchuang Zouhuang (Carbuncle with systemic toxicity/toxic heat invading the interior): *Liangpeng Huiji* (Collection of Good Friends' Prescriptions) records: This prescription originated from Prime Minister Zhang of Baodi. It is 100% effective and truly a miraculous formula. Whenever Carbuncle Zouhuang occurs, where toxin attacks inward causing loss of consciousness, rescue is possible as long as breath remains. Take one Mianqie fruit, place it in a porcelain bowl with yellow wine, and grind the fruit within the wine until fully processed, equivalent to the time it takes to brew a pot of tea. Pour the wine into a long-necked tin pot. Add two green onions with roots intact (bit by teeth without breaking), seven white cowpeas, and if it is the season when buckwheat blooms, add seven buckwheat grains (not used in other seasons). Additionally, use wheat, chewed by multiple people into a glutinous paste (mianjin), to seal the mouth of the pot. Place the pot in a water bath and boil for the duration of one incense stick. Remove and drink hot; recovery follows sweating.
