Purslane


Purslane

A genus of 100 species of fleshy, trailing annuals, with a few perennials, found widely in dry, sandy soils in warm temperate and tropical regions. Portulaca oleracea is grown as a vegetable in many parts of the world. It was known to the ancient Egyptians and has also been grown for thousands of years in India and China. France is now the main European producer and consumer. Cultivated purslane is sometimes treated as a distinct variety, var. sativa. Research has shown the P. oleracea is a rich source of omega-3 fatty acids, which are thought to be important in preventing heart attacks and strengthening the immune system. Portulaca oleracea was first described in Chinese medical literature c.CE500. In Coptic medicine it was used for sore eyes, skin inflammations, and "anything swollen", as it is in Egypt today. Portulaca grandiflora (sun plant, rose moss) is also used, mainly in the form of fresh juice, for hepatitis or as a lotion for snake and insect bites, burns, scalds, and eczema. Portulaca is the original Latin name, used by Pliny.

Annual with thick, soft, trailing stems and thick, fleshy, spoon-shaped leaves, to 3cm (1¼in) long. Small yellow flowers, with 4-6 petals, are produced in summer, then many-seeded capsules.
