"It has an extensive natural distribution throughout the Old World extending from North Africa through the Middle East and the Indian Subcontinent to Malesia and Australasia. The species status in the New World is uncertain... It is naturalised elsewhere and in some regions is considered an invasive weed... Although purslane is considered a weed in the United States, it may be eaten as a leaf vegetable. It has a slightly sour and salty taste and is eaten throughout much of Europe, the middle east, Asia, and Mexico. The stems, leaves and flower buds are all edible." | "It has an extensive natural distribution throughout the Old World extending from North Africa through the Middle East and the Indian Subcontinent to Malesia and Australasia.

+ | "An aqueous extract of the stems and leaves of Portulaca oleracea abolishes the twitch contraction of the directly stimulated rat hemidiaphragm preparation. The effects of the extract mimic qualitatively the action of potassium oxalate - a known constituent of Portulaca oleracea - on the diaphragm. Removal of K+ ions from the methanol extract by passing it through a cation exchange resin reduced the inhibitory effect of the extract. There was a positive correlation between the concentration of K+ ions in the extract and the effects of potassium chloride of similar molarity. It is concluded that the K+ ion content of Portulaca oleracea is at least partly responsible for the relaxant effect observed on the isolated rat diaphragm." | ||

+ | fresh weight. The stems and buds contained a mean of 75.0% soluble oxalates while the leaves contained only 27.5% soluble oxalates. Boiling the leaves, stems and buds resulted in a loss of soluble oxalates from the tissue which resulted an overall 27% reduction in total oxalate in the tissues. Pickling the whole plant resulted in a loss of soluble oxalates from the tissue by leaching into the vinegar, resulting in a reduction of total oxalate content of the pickled tissue by 16%. Larger leaves contained 40% more total oxalates than the small leaves while the oxalate content of the stems ranged between 4.9 and 6.2 g total oxalates kg-1 | ||
