Purslane (Portulaca oleracea) is often dismissed as an ordinary garden weed, yet it has been eaten as a leafy vegetable for centuries in many parts of the Mediterranean, Europe and Asia.
Its nutritional profile has attracted scientific interest because it provides several vitamins, minerals, antioxidants and an unusual amount of plant-based omega-3 fatty acids for a leafy vegetable.
But while purslane can be a nutritious addition to the diet, claims that it can “cure everything” go far beyond what scientific evidence currently supports.
A Notable Plant Source of Omega-3 Fatty Acids
One of purslane’s most interesting characteristics is its alpha-linolenic acid (ALA) content.
ALA is an essential omega-3 fatty acid that the body cannot make on its own. Research comparing purslane with other leafy vegetables has found particularly high levels of ALA in its leaves.
That doesn’t make purslane a replacement for medical treatment or other established sources of omega-3s,
