生长在溪流、山涧、水田和港口静止的水中，如果是流动的水则不生长。形状像蕨类植物的嫩芽，中间有一根茎，两旁细叶成对聚集，形状像蜈蚣，因此得名。
叶子相当粗糙涩手，不像浮萍那样有光泽。《本草纲目》“水藻”集解部分下有马藻，叶子也是对生，形状也略微相似，但实际上不是同一种东西。
大概是因为藻类可以吃，而这种植物不可食用，所以主治功效也不同。民间俗称边箕萍。《群方谱》记载：它是麻萍的异种，长度大约一指左右，叶子相对连接缀合，不像普通浮萍那样点点清轻。
治疗虱子：《同寿录》记载：将蜈蚣萍晒干后烧烟熏蒸，则所有的跳蚤、壁虫都能清除。

治疗小儿各种疾病及痧胀，需要作为重要药物使用。
李氏《草秘》：这种草叶子对生，茎圆梗，生长在靠近田间水沟的地方。
It grows in streams, mountain gullies, paddy fields, and ports in still water; it does not grow in flowing water. Its shape resembles the young fronds of ferns, with a single central stem and fine leaves gathered oppositely on both sides, resembling a centipede, hence the name.
The leaves are quite rough and astringent to the touch, unlike the glossy surface of *Lemna minor* (Duckweed). In the "Collection of Explanations" under "Aquatic Algae" in *Bencao Gangmu* (Compendium of Materia Medica), there is *Alisma plantago-aquatica* (Water-plantain/Ma Zao), which also has opposite leaves and a slightly similar shape, but is actually a different species.
Presumably, because algae are edible while this plant is not, their therapeutic indications differ. It is commonly known as Bianji Ping. *Qunfang Pu* states: It is a variant of Maping, growing about one finger's length long, with leaves connected oppositely, unlike the scattered, light nature of common duckweed.
Note: Maping refers to what is now known as Centipeda minima (Wugong Ping).
For treating lice: *Tongshou Lu* records: Dry Centipeda minima, burn it to produce smoke, and fumigate with it; all fleas and bedbugs will be eliminated.
Supplement from *Longbai Yaoxing Kao*: Originates from Shandong.
Taste: Bitter with a slight pungency. Actions: Dispels wind, unblocks meridians, invigorates blood, strengthens sinews and bones, and promotes circulation through collaterals. Indications: Trauma, bi-syndrome (painful obstruction), numbness, and skin wind conditions. Soaking it in wine for regular consumption yields significant effects. Alternatively, add Cinnamon Twig (*Guizhi*), Angelica Sinensis (*Danggui*), Safflower (*Honghua*), and White Peony Root (*Shaoyao*) to the formula. The stem tips are used medicinally.
From Wang Lianshi's *Herbal Formulas*: The variety of *Glochidion puberum* (Guixiangyou) with fine leaves is called Tianxiangyou. Crush the roots and leaves together to extract juice; its taste resembles sesame oil, hence the name.
From Li's *Grass Secrets*: The seedlings and leaves of Guixiangyou resemble Elsholtzia splendens (Xiangru).
Case: A man suffered from swelling and pain in his thigh for two or three months, with internal suppuration that could not drain, leaving him in critical condition. Applying this herb caused the pus to burst out; after several doses, he recovered. Apply the juice of this herb mixed externally to treat various boils, carbuncles, pumpkin abscesses (Donggua Yong), and osteomyelitis (Fugu Ju). According to Li's *Grass Secrets*: For pumpkin abscesses and osteomyelitis, combine this herb with one qian of Licorice Root (*Gancao*), add salt crystals from soy sauce boards, crush them together, and apply externally with effectiveness. It moistens the skin, nourishes complexion, and resolves toxic sores. Locals use it only for snake bites, bee stings, and thorn injuries by rubbing the leaves on the affected area. (Source: Wang Lianshi's *Herbal Formulas*.)
Supplement from *Longbai Yaoxing Kao*: Originates from Pingle County, Guangxi.
Indication: An essential medicine for treating various pediatric diseases and sha-distension (sand distension).
From Li's *Grass Secrets*: This herb has opposite round-stemmed leaves and grows near field ditches.
Indication: For trauma, contusions, swelling, and fractures, crush and take the juice internally; apply externally to various swellings and toxins.
From Wang Lianshi's *Herb Gathering Book*: Caoli Jinchai produces yellow flowers, with a single slender stem rising straight up, resembling Xingtou Cao. It treats traumatic injuries (Jin Chuang) by invigorating blood, and addresses cloudy urine (Baizhuo) and spermatorrhea (Yijing).
Kai Bai Chai Cao treats leukorrhea (Baidai) and excessive vaginal discharge (Baiyin) in women; decoct it with raw white liquor for administration.
