Notes

Leaves and stems - raw or cooked[1][2][3][4][5]. The young leaves are a very acceptable addition to salads, their mucilaginous quality also making them a good substitute for okra as a thickener in soups[2][6]. Older leaves are used as a potherb[2]. The leaves have a somewhat sour flavour[7]. A spicy and somewhat salty taste[8]. The leaves are a source of omega-3 fatty acids, though seed sources such as walnuts are magnitudes richer[9]. The leaves can be dried for later use[7]. They contain about 1.8% protein, 0.5% fat, 6.5% carbohydrate, 2.2% ash[10]. Another analysis gives the following figures per 100g ZMB. 245 - 296 calories, 17.6 - 34.5g protein, 2.4 - 5.3g fat, 35.5 - 63.2g carbohydrate, 8.5 - 14.6g fibre, 15.9 - 24.7g ash, 898 - 2078mg calcium, 320 - 774mg phosphorus, 11.2 - 46.7mg iron, 55mg sodium, 505 - 3120mg potassium, 10560 - 20000ug B-carotene equivalent, 0.23 - 0.48mg thiamine, 1.12 - 1.6mg riboflavin, 5.58 - 6.72mg niacin and 168 - 333mg ascorbic acid[11].

Seed - raw or cooked[12][13][14]. The seed can be ground into a powder and mixed with cereals for use in gruels, bread, pancakes etc[6][15]. The seed is rather small and fiddly to utilize[7]. In arid areas of Australia the plants grow quite large and can produce 10, 000 seeds per plant, a person can harvest several pounds of seed in a day. The seeding plants are uprooted and placed in a pile on sheets or something similar, in a few days the seeds are shed and can be collected from the sheet[15]. In Britain, however, yields are likely to be very low, especially in cool or wet summers[K]. The seed contains (per 100g ZMB) 21g protein, 18.9g fat 3.4g ash[11]. Fatty acids of the seeds are 10.9% palmitic, 3.7% stearic, 1.3% behenic, 28.7% oleic, 38.9% linoleic and 9.9% linolenic[11].

The ash of burnt plants is used as a salt substitute[6].

Medicinal uses(Warning!)

The plant is antibacterial, antiscorbutic, depurative, diuretic and febrifuge[2][16][17][18][19]. The leaves are a rich source of omega-3 fatty acids, which is thought to be important in preventing heart attacks and strengthening the immune system[19]. Seed sources such as walnuts, however, are much richer sources[9]. The fresh juice is used in the treatment of strangury, coughs, sores etc[2][16][17][18]. The leaves are poulticed and applied to burns[9], both they and the plant juice are particularly effective in the treatment of skin diseases and insect stings[16][19]. A tea made from the leaves is used in the treatment of stomach aches and headaches[9]. The leaf juice is applied to earaches, it is also said to alleviate caterpillar stings[9]. The leaves can be harvested at any time before the plant flowers, they are used fresh or dried[19]. This remedy is not given to pregnant women or to patients with digestive problems[19]. The seeds are tonic and vermifuge[11][20]. They are prescribed for dyspepsia and opacities of the cornea[11].

Propagation

Seed - for an early crop, the seed is best sown under protection in early spring and can then be planted out in late spring[2]. Outdoor sowings in situ take place from late spring to late summer, successional sowings being made every two to three weeks if a constant supply of the leaves is required[2].

Cultivation

Requires a moist light rich well-drained soil in a sunny position[2][5][21]. Plants will not produce good quality leaves when growing in dry conditions[2].

A perennial plant in warmer climates than Britain, purslane is killed by frost but can be grown as a half-hardy annual in this country[1]. It can become an aggressive weed in areas where the climate suits it[22].

Occasionally cultivated for its edible leaves, this is a form of purslane with golden/yellow leaves. Plants take about six to eight weeks to produce a crop from seed and can then be harvested on a cut and come again principle[2].
