Edible Uses

Edible Parts: Leaves  Root  Stem
Edible Uses: Gum

Young leaves - raw or cooked[2, 4, 9, 13, 54]. This species has the nicest tasting leaves of the genus[153], they usually have a mild agreeable flavour[217] especially in the spring[K]. They can be added to salads, cooked like spinach or used in soups etc[183]. The leaves contain about 30 - 40mg of vitamin C per 100g[173], 1.2% protein, 0.3% fat, 2.4% carbohydrate, 1.2% ash[179]. A zero moisture analysis is also available[218]. It might be best, though it is not essential, to remove the marginal prickles[9]. Stems - cooked like asparagus or rhubarb[12]. They are best if the outer skin is removed first[183]. Young root - cooked[12]. They are woody and not very acceptable[144]. The milky sap has been used as a chewing gum by the Maoris of New Zealand[183].

Cancer  Emmenagogue  Febrifuge  Hepatic  Hydrogogue  Poultice  Tonic  Vitamin C  
Warts

The plant is emmenagogue and hepatic[61, 257]. An infusion has been used to bring on a tardy menstruation and to treat diarrhoea[257]. The latex in the sap is used in the treatment of warts[218]. It is also said to have anticancer activity[218]. The stem juice is a powerful hydrogogue and cathartic, it should be used with great caution since it can cause colic and tenesmus[218]. The gum has been used as a cure for the opium habit[257]. The leaves are applied as a poultice to inflammatory swellings[4]. An infusion of the leaves and roots is febrifuge and tonic[240].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

The latex in the stem contains 0.14% rubber, but this is much too low for commercial exploitation[218]. The plant is a good companion for onions, tomatoes, corn as well as the cucumber and squash family[14].

Cultivation details

Succeeds in most soils in a sunny position. This plant has been cultivated for its edible leaves by the Maoris of New Zealand[153]. The plant is a good companion for onions, tomatoes, corn as well as the cucumber and squash family[14]. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is rhizomatous with underground stems sending roots and shoots along their length [2-1].
