Notes

Teder young shoots and leaves - raw or cooked as a pot-herb[1][2][3][4][5]. The leaves and young shoots are harvested in the spring when about 8cm long[6]. Strongly aromatic according to one report[4] whilst others say that it is rather smelly and somewhat like rotten fish[7][8]. Our experience is that the leaves have a delicious orange-like smell and make a marvellous flavouring in salads[K]. One report says that there are two distinct chemotypes of this species. Plants from Japan have an orange scent, whilst those from China have a smell resembling coriander leaves (Coriandrum sativum)[9]. Some people seem to really like this leaf, others are indifferent to it or strongly dislike it[K]. It also varies quite considerably according to the time of year. In the spring and summer it has a very acceptable flavour, but by autumn a distinct bitterness has crept in[K].

Root - cooked[10][4]. Same comments on the smell as for the leaves[7].

Fruit[4]. No further details[K], but the fruit is a capsule that contains many small seeds[11].

Material uses

A good ground cover plant[11]. Plants do not form a weed-suppressing cover[K]. A spreading plant, it should be spaced about 45cm apart each way[12].
There are no material uses listed for Houttuynia cordata.

Medicinal uses(Warning!)

The whole plant is antibacterial, antiinflammatory, antimicrbial, antiphlogistic, antiviral, depurative, diuretic, emmenagogue, febrifuge, hypoglycaemic, laxative and ophthalmic[3][13][14][15][16][17][9][18][19]. A decoction is used internally in the treatment of many ailments including cancer, coughs, dysentery, enteritis and fever[17]. Its use is said to strengthen the immune system[16]. Externally, it is used in the treatment of snake bites and skin disorders[9]. The leaves and stems are harvested during the growing season and used fresh in decoctions[9].

The leaf juice is antidote and astringent[17]. A root extract is diuretic[17][18]. The root is also said to be used in medicinal preparations for certain diseases of women[18][20]. The rhizomes yield a sterol, resembling sitosterol, which stimulates the secretion of antibiotic substances from a gram-positive spore-forming bacillus[18].

An active substance, effective in the treatment of stomach ulcers, has been extracted from the plant[18].

Propagation

Seed - sow spring in a greenhouse. Prick out the seedlings into individual pots as soon as they are large enough to handle and plant them out in the summer. Division in spring[21][22]. Very quick and easy, it can be done successfully at almost any time in the growing season[K]. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.

Cultivation

Requires a moist to wet soil or shallow water, partial shade and a sheltered position[23][21][22][9]. Whilst it grows best in a bog garden, it will succeed in moist garden borders[24] and has also grown fairly well in a dry soil in Cornwall[K]. It succeeds in full shade[12].

Plants are hardy to about -15°c[25], the top growth is killed back by frost though the roots are much hardier. Even the roots, though, can be killed in severe winters[22]. A very ornamental plant, there are some named varieties[25]. 'Chameleon' has very attractively variegated leaves with the same flavour as the species[K]. The bruised leaves emit a strong citrus smell rather like orange peel[K]. Plants have a widely spreading root system and are very invasive, though they are easier to control in drier soils[11]. Creeps harmlessly between ferns[25]. Cultivated as a salad crop in Vietnam[3] and in W. China[25]..

Plants seem to be immune to the predations of rabbits[24]. Plants growing in an area with a high rabbit population were not eaten by them although other plants growing nearby were attacked[K].
