Purslane, known scientifically as Portulaca oleracea and colloquially as pigweed, little hogweed or fatweed, is far more than a stubborn garden invader. In Mediterranean Europe and parts of Asia, it’s prized as a leafy vegetable—and with good reason. This succulent plant thrives in poor soil and drought, yet delivers a remarkable nutritional punch. Traditional Chinese medicine even hails it as “the vegetable for long life.”
What makes purslane so special? For starters, its fleshy leaves are brimming with vitamins A, C and E, all powerful antioxidants that help protect cells from damage. Vitamin A’s beta‑carotene supports healthy vision, vitamin C fortifies skin and immune function, and alpha‑tocopherol (a form of vitamin E) shields cell membranes. Purslane also supplies glutathione and betalains—additional antioxidant compounds—and a touch of melatonin, the sleep‑regulating hormone.
Beyond antioxidants, purslane delivers minerals essential for overall health. It’s a solid source of potassium, which helps regulate blood pressure and supports heart health, and calcium, critical for bone strength, nerve transmission and kidney function. Magnesium rounds out its mineral profile, playing roles in blood sugar control, muscle and nerve function, protein synthesis and bone building. Because these nutrients come from whole foods, they’re generally more bioavailable than in supplements.
Perhaps most surprising is purslane’s omega‑3 content. While fish like salmon often steal the spotlight, purslane contains significant amounts of alpha‑linolenic acid (ALA) and the rarer eicosapentaenoic acid (EPA), fats our bodies cannot produce on their own. In fact, its ALA levels are five to seven times higher than those found in spinach, and the presence of plant‑based EPA is virtually unique among land vegetables. These fatty acids support heart, brain and joint health, making purslane an exceptional vegan source of omega‑3s.
Because purslane is about 93 percent water, it’s low in calories but high in nutrients—a perfect candidate for salads, sandwiches, smoothies or cooked dishes. Its slightly tart flavor pairs well with tomatoes in a Mediterranean‑style salad, and it can replace spinach in quiches or pesto. Toss it into soups, stir‑fries or grilled vegetable medleys for a nutritional boost.
Yet purslane isn’t without caveats. It contains oxalates—natural compounds that can bind to minerals like calcium and iron, reducing their absorption and, in susceptible individuals, forming kidney stones. People with a history of kidney stones or conditions such as inflammatory bowel disease may need to moderate their intake and consult a healthcare provider before making purslane a regular part of their diet.
Cultivating purslane is surprisingly easy. This annual plant flourishes in full sun, tolerates poor, even salty soil, and requires minimal watering once established. It spreads quickly across garden beds or spills charmingly from hanging baskets, but it cannot withstand frost—harvest your crop during warm months before the first cold snap.
From its rich vitamin and mineral profile to its uncommon plant‑based omega‑3s and antioxidants, purslane stands out as a nutritional powerhouse disguised as a weed. Whether you forage a patch in your yard or sow it deliberately in your garden, this humble succulent offers health benefits that have earned it a place in cuisines and folk remedies around the globe.
