鱼鳖金星草，又名凤尾金星草。
它还有一个名字叫独脚金鸡，又被称为鸭脚金星，佩戴它可以辟除疫气。近来我在市场上见到的，有小叶且短狭的，有大叶且长狭的，这些都不是真正的辟瘟草。小的那种名叫七星草，俗称骨牌草。这种草之所以没有“五”和“六”这两个字（指形态或名称特征），是因为“五”和“六”代表天地之中数，难以形成固定结构，它们寄生在石头和树木之间。大的那种名叫剑脊金星，长度有一二尺，生长在山间溪流的旁边，老了之后叶子背面都会出现星状斑点，这两种草药，《本草纲目》东壁部分已经收录记载了。
真正的辟瘟草叶子像鸭脚，分为三叉，一茎一叶，气味清香，老了之后会有星状斑点，但香气也会减弱。《百草镜》说：鸭脚金星就是辟瘟草。叶子像鸭脚，大而薄，背面生有星点，到了八九月间，星星变老后变成黄色，晒干后，其香气凛冽且不改变；如果叶子太老或者经过水洗，就不香了。端午节采摘嫩叶阴干使用，不要见火。
药性平和，味道苦，气味香，治疗伤寒、疟疾、痢疾，风气引起的肿胀毒邪，时行疫病和秽浊之气，疏散邪风，治疗乳痈、热疮，小儿痘疹、眼疾、疳积，以及喉痹、痧胀，香气能通窜疏通经络，治疗疳积。
《百草镜》记载：治疗痧胀用鸭脚金星草，晒干研成粉末。取少许吹入鼻中，或者煎汤服用也可以。
小泉验方记载：治疗疔疮肿毒用鸭脚金星草煎酒，服一次就能消散。
鱼鳖金星草生长在背阴的山石上，立夏后发出苗芽，根细如纤线，蔓延在石头上，叶子不对生节位，一片长形一片圆形，长形的像鱼，圆形的像鳖，鱼叶经霜后变老，背面起金星，只有鳖叶没有金星，也生长在西湖飞来峰的最高处。
治疗鼓胀、瘰疬、火毒症。《采药志》说：药性凉，治疗痰火毒邪上行至身体上部。（《采药方》记载：消除痞块、痰核、腮部肿痛。）
永师方记载：治疗烟筒戳伤喉咙，用鱼鳖金星草煎浓汤，咽喉受到内伤，立即止痛并痊愈。（永师方即永宁传方。）
*Adiantum capillus-veneris* (Fish-Turtle Star-Venus Grass), also known as *Phoenix Tail Star-Venus Grass*.
It is also called *Single-Foot Golden Rooster* and *Duck-Foot Star-Venus*; wearing it can ward off epidemic pathogens. Recently, what I have seen in the market includes varieties with small, short, and narrow leaves, or large, long, and narrow leaves; none of these are the true *Biwencao* (Calamity-Dispelling Grass). The smaller variety is named *Qixingcao* (Seven-Star Grass), commonly called *Gupai Cao* (Bone-Chess Grass). It lacks the characters "five" and "six," likely because five and six represent the central numbers of Heaven and Earth, which do not easily form fixed structures; it grows as an epiphyte between rocks and trees. The larger variety is named *Jianji Jinxing* (Sword-Spine Star-Venus), measuring one to two chi in length, growing beside mountain streams; when old, stars appear on the abaxial surface of all leaves. These two varieties have already been recorded in the *Dongbi* section of the *Bencao Gangmu* (Compendium of Materia Medica).
The true *Biwencao* has leaves resembling duck feet, trifid (divided into three parts), with one leaf per stem, possessing a clear and fragrant aroma; when mature, star-like spots appear, but the fragrance diminishes. *Baicao Jing* (Mirror of Hundred Herbs) states: Duck-foot Star-Venus is indeed the Biwencao. Its leaves resemble duck feet, are large and thin, with star-like spots on the back; by the eighth and ninth lunar months, the stars turn yellow upon maturation. After drying, its aroma remains pungent and unchanged; however, if the leaves are too old or washed with water, they lose their fragrance. Harvest the tender leaves on the Dragon Boat Festival (Duanwu), dry them in the shade, and avoid exposure to fire.
Nature is neutral, taste is bitter, aroma is fragrant. It treats *Shanghan* (Cold Damage), malaria, dysentery, swelling and toxicity caused by wind-pathogens, seasonal epidemics, and foul qi. It disperses evil wind, treats *Ruyong* (Mastitis), heat sores, pediatric variola (smallpox), eye diseases, and *Gan* syndrome (childhood malnutrition/accumulation); it also treats *Hou Bi* (sore throat/throat obstruction) and *Sha Zhang* (sha distension/poisoning). Its aromatic nature penetrates and unblocks meridians, treating Gan syndrome.
*Baicao Jing*: To treat Sha Zhang, use Duck-foot Star-Venus grass, dried and powdered. Take a small amount and insufflate into the nose, or decoct and drink.
Xiaoquan Empirical Formula: For *Ding Zhong* (carbuncles/swellings), decoct Duck-foot Star-Venus grass in wine; one dose causes immediate resolution.
It grows on shaded mountain rocks. After Lixia (Start of Summer), shoots emerge; roots are fine like threads, spreading over rocks. Leaves are not opposite at nodes; one is elongated, the other round. The elongated ones resemble fish, the round ones resemble turtles. Fish-leaves become old after frost, developing star-spots on the back; turtle-leaves lack these spots. It also grows at the summit of Feilai Peak in West Lake.
It treats *Guzhang* (tympanites/distended abdomen), *Luoli* (scrofula), and fire-toxin diseases. *Caizao Zhi* (Record of Herb Gathering) states: Nature is cool; treats phlegm-fire toxin ascending to the upper body. (*Caizao Fang* [Recipe for Herb Gathering]: Resolves masses, phlegma nodules, and mumps.)
Master Yong's Formula: For throat injury caused by a pipe puncture, decoct Fish-Turtle Star-Venus grass into a thick decoction. For internal throat injuries, it immediately stops pain and heals. (Master Yong's Formula is also known as the Yongning Transmission Formula.)
