*Guangdong Tongzhi* records: The fruit of *Miwang* turns yellow in the fifth lunar month, with a sweet and sour taste. Those crossing the sea purchase it at a high price. There is a plant called "Yaotao" similar to *Miwang*, which ripens in the sixth and seventh lunar months; its fruit is as large as a papaya. Anyone crossing the sea who consumes it will not suffer from seasickness or vomiting.

*Zhaoqing Fuzhi* records: *Miwangzi* is also known as Mangguo. The tree grows several zhang high, blooms extremely profusely, and bees gather joyfully upon seeing the flowers, hence the name. *Jiaoguang Lu* records: In the second lunar month, *Miwang* is also called Wangguo. Its relative includes Yaotao, which blooms in the fifth lunar month and ripens in the sixth and seventh. In years of famine, Yaotao produces even more fruit. A Guangdong folk song says: "When rice prices are high, eat Yaotao." Thus, people in Guangzhou value Wangguo but despise Yaotao. It is valued because it is "expected" (Wang); bees expect its flowers, and humans expect its fruit.

**Stopping Seasickness**: [Commentary] Seasickness is called "Kuchuan" by northerners. "Ku" sounds like "Ku". This syndrome often presents with vomiting and loss of appetite, resolving upon disembarkation. It is common among those with weak Stomach Qi. *Miwang* fruit is sweet and sour, can tonify Stomach Qi, and thus can stop vomiting and seasickness.

*Luofu Zhizhi* records: The Putao tree is two to three zhang high. Its leaves resemble Cassia leaves. It blooms year-round. The flowers consist of clusters of filaments without petals, resembling cut silk balls, about one cun long, colored yellow-green. The fruit resembles an apple, with a shell half a finger thick, extremely sweet and fragrant. The seed is not attached to the shell; shaking it makes a rattling sound. These trees are abundant in the streams of Luofu Mountain. Monkeys and birds peck at them, and the flesh floats out with the current. Mountain dwellers dam the water to collect them, obtaining several hu at a time. Brewing this fruit yields wine called "Putao Chun," whose fragrance remains unchanged after a year. Making it into a paste is particularly delicious.

*Tong Beiyan Shigui* records: Wuyu powder originates from Qiannan, Jiangxi. Locals produce it using the method for lotus root starch, selling it to distant regions as food. It is also known as Wuyu powder or Black Bibi. It is sweet, cold, non-toxic. It dissolves copper rust and breaks down hard accumulations, removes epigastric masses and stagnation, resolves Dan Shi toxicity and Gu poison, clears the Heart to remove nebulae, eliminates damp-heat from the Lung and Stomach meridians, treats hoarseness due to wind injury from excessive drinking, and promotes the eruption of dry, purple sores (from *Beiyan Shigui*).

Shan Bibi grows in mountain soil. In spring, it sprouts seedlings with three leaves, resembling chives but finer, with shiny leaves. The root is bean-sized, growing larger with age. The root is used medicinally and is also called Shan Bibi. Grinding the root into powder, filtering through water, and drying it for eye application removes nebulae miraculously (avoid iron vessels when extracting powder).

[Commentary]: Shan Bibi prefers dryness and must grow on highland dry soil to proliferate easily. When transplanted into gardens, if exposed to dirt and moisture, the roots rot quickly.

Regarding Qian Daer: Previously, while staying in Dong'ou, I heard that Master Ma's eye drop powder was the best under heaven. Observing his preparation, I found he ground Shan Bibi powder and mixed it with Haiqiumu and Zhenzhu powder, yielding exceptional efficacy. It is said to remove facial dark spots and moles, dissipate masses, and eliminate star-shaped protrusions and pterygium in the eyes. Compared to Bibi produced in marshy areas, its action is more potent.

**Mogu San** (*Zhongfutang Fang*): A divine eye-drop formula. Wash and peel wild Bibi powder, pound in a stone mortar, squeeze juice through fine silk, similar to making lotus root starch. Then, levigate calcined calamine (Luganshi) with clear well water and dry it. Decoct Huanglian, Huangbai, Huangqin, Ganju, and Bohe in water, adding Tongbian (child's urine) once. Levigate and dry Zhenzhu with the decoction, boil in tofu, grind finely, and levigate again. For every 1 liang of dried Bibi powder, mix with 5 qian of processed Luganshi and appropriate amount of Zhenzhu powder for eye application.

**Secret Formula for Brightening Eyes and Removing Nebulae** (*Zhongfutang Fang*): Take 1 liang of Jinwen Dahuang and 4 liang of Beixixin. Add 120 liang of high-quality spring water. Place herbs in a clay pot, decoct until 20 liang remain. Filter through fine silk. Pour into a large silver bowl placed on three bricks. Under the bowl, place a lamp with sesame oil and seven rush wicks to smoke the bottom of the bowl, reducing the liquid to a paste consistency (drop forms a bead). For each 1 liang of paste, add 5 qian of wild Bibi powder (more is acceptable) and 3 fen of Bingpian. Mix evenly to form pills. For old, dense nebulae, add 5 fen of Chan Tui powder (washed, dried, ground, levigated three times) per 1 liang of paste. Another method: Mix equal parts wild Bibi powder and Zhu Yi. Place in half an eggshell. Apply to Yintang before sleep. Wait for fluid to enter the eyes; nebulae exit with tears. Cured in 20 days. Also treats "River Snail Head Eye" disease.
