Houttuynia cordata
From Wikipedia, the free encyclopedia
outtuynia cordata (simplified Chinese: 鱼腥草;
traditional Chinese: 魚腥草; pinyin: yúxīng cǎo;
literally "fishy-smell herb"; Japanese: Dokudami 蕺草,
literally "poison blocking plant";
Vietnamese: giấp cá; pak kao tong (ຜັກຄາວທອງ) in Lao; Korean: 약모밀.
In English, it is known as lizard tail,
chameleon plant, heartleaf, fishwort and bishop's weed.
[1] It is one of two species in the genus Houttuynia,
is a flowering plant native to Japan, Korea,
southern China and Southeast Asia,
where it grows in moist, shady places.
Growth [edit]
Houttuynia cordata is a herbaceous perennial plant growing to between 20 and 80 cm.
The proximal part of the stem is trailing and produces adventitious roots,
while the distal part of the stem grows vertically. The leaves are alternate,
broadly heart-shaped, 4–9 cm long and 3–8 cm broad. Flowers,
growing usually in Summer, are greenish-yellow,
borne on a terminal spike 2–3 cm long with 4-6 large white basal bracts.
Cultivation
The plant grows well in moist to wet soil and even slightly submerged in water
in partial or full sun. Plants can become invasive in gardens
and difficult to eradicate. Propagation is via division.
In temperate gardens, it is usually in one of its cultivated forms,
including: Chameleon (synonymous with H.c. 'Court Jester', H.c. 'Tricolour',
H.c. 'Variegata') this variety is slightly less vigorous than the species
and has leaves broadly edged in yellow and flecked with red;
Flore Pleno has masses of white bracts and the vigour of the parent species.
Usage [edit]
Culinary use
Grown as a leaf vegetable, particularly in Vietnam,
where it is called giấp cá or diếp cá and is used as a fresh herbal garnish.
The leaf has an unusual taste that is often described as fishy (earning it the nickname "fish mint"),
so it is not enjoyed as universally as basil, mint, or other more commonly used herbs.
In North-Eastern India particularly Meghalaya,
it is locally known as "Ja mardoh" and used in salads or cooked with other vegetables.
In the southwestern Chinese provinces of Yunnan, Guizhou, and Sichuan,
roots are used as a root vegetable. English names include heartleaf, lizardtail, and fishwort.
Traditional use [edit]
Houttuynia cordata is also used in used in folk medicine for diuresis and detoxification and herbal medicine for its antiviral, antibacterial and antileukemic activities.[2][not in citation given] Recently it has been suggested that it might have anti-obesity properties.[3] Houttuynia cordata was used by Chinese scientists to tackle SARS as it is conventionally used to treat pneumonia.[4]
H. cordata injection, a traditional Chinese medicine, is often used to relieve abnormal lung symptoms, infectious disease, refractory hemoptysis and malignant pleural effusion in China.[citation needed] H. cordata injection has a direct inhibitory activity against Pseudorabies herpes virus in vitro.[5]
It is used in traditional Chinese medicine and can (in injection form) cause severe allergic reactions.[6]
In Japan, the beverage dokudami cha (Japanese: ドクダミ茶; literally "Houttuynia cordata tea") is made from the dried leaves, widely used as a general detox for ridding the body from harmful bacteria.
