Purslane: A Tasty
Purslane provides various beneficial nutrients at the cost of very few calories.

Purslane (scientific name: Portulaca oleracea), also called pigweed or little hogweed, is a succulent plant found worldwide. It can be eaten raw and cooked and is popularly used in various cuisines.

Leaves, stems, and flowers of purslane are edible and have a tart or salty taste. They are used for making salads, garnishing, and making soups and other savory dishes.

Despite being called a weed, purslane is quite beneficial for your health. It is used in alternative medicine to treat health conditions such as diabetes, oral lichen planus, asthma, and menstrual irregularities. There is, however, little scientific evidence to support these uses.

Nonetheless, it is full of vitamins, omega-3 fatty acids, minerals, and other beneficial compounds that promote health and well-being.

    • Folate and choline: Although choline is considered neither a vitamin nor a mineral, it is classified with B vitamins because of several similarities they possess. Folate and choline are important for healthy nervous system development in fetuses. Folate is required for red blood cell formation and cell growth and functioning. Choline helps with the proper functioning of the liver and brain.

Are there any risks of eating purslane?

Although purslane is safe when eaten as a food, its usage as medicine has little safety information available so far.

Pregnant women and lactating mothers must particularly avoid consuming it in excess. Research suggests that purslane may stimulate uterine contractions in pregnant women and can thus result in premature birth or miscarriage.

Some studies report that purslane increases urine formation although little data are available to ascertain its effect on kidney health. Because purslane is rich in oxalates, it can increase the risk of kidney stone formation.

Oxalates may interfere with the absorption of important minerals such as calcium. There is a risk of certain drug interactions with purslane, especially if you take multiple medications.
