Used plant part

Fresh leaves. The rhizome, too, is aromatic, and is used in Manipur, a small area in North-Eastern India bordering Burma.

Plant family

Saururaceae (lizard tail family)

Sensory quality

Of this species, two different chemotypes (i.e., plants with different constituents, but otherwise identical features) are known: The Chinese/Vietnamese chemotype resembles coriander in its aroma, and the Japanese chemotype is characterized by a strange lemon or orange odour that is often compared to ginger; see also lemon myrtle on lemony spices. Some have compared the fragrance of chameleon herb with raw meat or fish, but I cannot agree.

The taste is aromatic, very close to Vietnamese coriander, but with an astringent aftertaste.

Main constitu­ents

The plant (Japanese chemotype) contains a variety of flavonoids, flavonoid glycosides (afzerin, quercitrin, isoquer­citrin) and pyridine alkaloids; the essential oil was found to consist mainly of decanal (caprylic alde­hyde), do­decanal (lauryl alde­hyde) and 2-hen­decanon (methyl nonyl ketone). (Planta Medica 61, 237, 1995)

Another work reports the essential oil’s main com­ponents being dodecanoic acid, 2-hen­decanon and methyl decanoate.

The volatile oil of the Chinese/Viet­namese chemotype was found to contain myrcene, 2-hen­decanon, limonene and decanoyl acet­aldehyde (3-keto­dodecanal). The latter compound seems mainly responsible for the characteristic flavour; it is a potent antibacterial agent. The plant is, thus, used in traditional Chinese medicine.

Origin

East Asia. Today, the plant grows wild in a vast area from Nepal via Thailand to Korea.

The chame­leon plant is often grown as an orna­mental in Europe and the USA; most popular are varie­gated culti­vars with attrac­tive three-coloured foliage.

Etymology

The scientific plant name is in honour of Maarten Houttuyn (1720 – 1798), a Dutch biologist.

The name lizard tail (properly referring to a closely related genus, Saururia) is motivated by the acute shape of the leaves in both Saururia and Houttuynia.

The name Chameleon plant (or chameleon herb) should be used only for the beautifully coloured variety which is most common as an orna­mental in the West, and whose triple-hued leaves (yellow, red, green) remember to the proverbial colour-shifting chameleon.

The English names fish­wort and heart­leaf refer, with some exagger­ation, to the plant’s strong odour and to the heart-shaped leaves, respec­tively. See also mugwort for the element -wort. A rather parallel name is Chinese yuxing cao [魚腥草] fish-stinking herb.

The Vietnamese name of the plant is diep ca [diếp cá], which is probably to be understood as lettuce (smelling like) fish; an alternative spelling is giap ca [giấp cá]. Other names reported, especially vap ca which is pretty common in English herbal literature, appear to be founded in writing errors in early Western reports. In Vietnam, that name is not known.

The leaves of the chame­leon plant are sometimes found in Viet­namese salads and gar­nishes. In Vietnam, many other fresh herbs serve the same purpose (see Viet­namese coriander). Their fresh, aromatic flavour goes even well with European salads.

The North-Eastern Indian union state Manipur boasts of a highly original cuisine, which uses not only leaves but also the fresh rhizome of chameleon plant; it emplys a host of further herbs (among others, a Mediterranan-like type of basil, cress, dill, coriander, long coriander, Vietnamese coriander). The preference for aromatic leaves and an excessive use of fermented fish flavours puts Manipuri food far apart from Indian mainstream cooking, making it more comparable to the cooking styles of neighbouring South East Asia.

In Mani­puri cuisine, chame­leon leaves are often em­ployed in salads like singju [সিংজু, ꯁꯤꯡজু], a mixture of raw leaves, lotus root slices and aromatic herbs; it is flavoured with nutty-tasting powder of sesame seeds, toasted legumes and pungent fermented fish; if available, slices of superhot local chiles (umorok [উমোরোক, ꯎꯃꯣꯔꯣꯛ]) might be sprinkled over it. Often, they are used in conjunction with fish, both fresh and fermented.

The chopped rhizome may also be used, particularly to cut the intensive fermented fish favour of the local signature food iromba [ইরোম্বা, ꯏꯔꯣꯝꯕꯥ], a type of liquid to dry vegetable curry with loads of fermented fish (ngari [ঙারি, ꯉꯥꯔꯤ]. The ground root is an in­gre­dient for fish curries. Leaves can also be dipped in a batter pre­pared from chick­pea flour to prepare a fresh-tasting pakora [पकोड़ा], locally known as bora [বোরা, ꯕꯣꯔꯥ]; the same is also done with other robust herbs like long coriander.
