(Arisaema tortuosum)

A. curvatum. (Roxb.)Kunth. Arum tortuosum.
Common Name Latin Name Plant Family
Arisaema tortuosum

The tubers have insecicidal properties[272].

  • Medicinal Use

    The roots have been used as a vermifuge in cattle[240, 243]. The juice of the tubers is applied to the wounds of cattle in order to kill any parasites[272]. The dried powdered tubers is applied to snake bites[272].

    The seeds have been mixed with salt and used to treat colic in sheep[240, 243, 272].

  • Edible Use

    Tuber – it must be thoroughly dried or cooked before being eaten[51, 177]. The tubers are boiled and eaten in Nepal, mixed with lime juice (Citrus aurantifolia) or another sour substance[272]. The tubers are buried in masses in pits until acetous fermentation takes place, they are then dug up, washed and cooked, by which means their acrimonious principles are in part dispersed[2]. However, violent illness has still been known to follow a hearty meal of the tubers[2]. See also the notes above on toxicity.

  • Cautionary Notes

    The plant contains calcium oxylate crystals. These cause an extremely unpleasant sensation similar to needles being stuck into the mouth and tongue if they are eaten but they are easily neutralized by thoroughly drying or cooking the plant or by steeping it in water.

Cultivation & Habitat

Seed – best sown as soon as it is ripe in a shady position in a cold frame[134]. Stored seed remains viable for at least a year and can be sown in spring in the greenhouse but it will probably require a period of cold stratification. Germination usually takes place in 1 – 6 months at 15¡c[134]. When large enough to handle, prick the seedlings out into individual pots and grow them on in light shade in the greenhouse for at least a coupe of years until the corms are more than 20mm in diameter. Plant out into their permanent positions whilst they are dormant. Division of tubers when the plant dies down in late summer.
Prefers a cool peaty soil in the bog garden, woodland garden or a sheltered border in semi-shade[134, 200]. Prefers a loamy or peaty soil and will tolerate a sunny position if the soil is moist but not water-logged and the position is not too hot or exposed[1, 200]. Plants are not very hardy outdoors in Britain and are normally best if given protection[1]. However, they can succeed outdoors in the milder areas of the country if the tubers are planted about 20cm deep[200]. Plants require protection from slugs[200]. Most species in this genus are dioecious, but they are sometimes monoecious and can also change sex from year to year. This species usually bears either monoecious or all male flowers[266].
