Many Confuse This Plant with a Weed, But Its Actually Full of Surprising Health Benefits
Purslane, known scientifically as Portulaca oleracea and often called pigweed, little hogweed, or fatweed, is much more than an ordinary weed. Revered as a nutritious leafy vegetable in regions spanning Asia to the Mediterranean, this resilient plant is celebrated not only for its ease of cultivation but also for its impressive array of vitamins and minerals. In traditional medicine—especially within Chinese practices—it has long been esteemed as a symbol of longevity.
This succulent green is a nutritional powerhouse. It provides generous amounts of vitamins A, E, and C as well as vital minerals such as calcium, magnesium, manganese, potassium, and iron. In addition to these, purslane contains modest levels of folate, phosphorus, copper, and a suite of B vitamins including B1, B2, and B3. Despite its high water content (roughly 93%), which keeps its calorie count low, purslane’s dense nutrient profile makes it a versatile addition to a wide variety of dishes.
One of the most remarkable features of purslane is its high omega-3 fatty acid content. While oily fish like salmon are typically celebrated as prime sources, purslane stands out among plant foods by providing significant quantities of omega-3s in the forms of ALA and EPA. Although many plants such as spinach contain ALA, purslane offers it in amounts five to seven times greater, and its EPA—a fatty acid usually limited to animal products and algae—is especially noteworthy for its greater bioavailability.
Beyond fatty acids, the antioxidants present in purslane offer substantial health benefits. Vitamin C supports strong bones, healthy skin, and muscular function, while vitamin A, rich in beta-carotene, promotes good vision. Additionally, the presence of alpha-tocopherol, a form of vitamin E, aids in protecting cell membranes from damage. Other antioxidant compounds found in this plant, such as glutathione, betalain, and even melatonin, further contribute to reducing oxidative stress and promoting overall well-being.
Purslane also shines as an excellent source of potassium, magnesium, and calcium. An adequate intake of potassium has been linked to lower blood pressure and improved cardiovascular health. Calcium is essential not only for robust bones but also for proper kidney function and digestion. Meanwhile, magnesium plays several critical roles in the body, including regulating blood sugar and blood pressure, supporting muscle and nerve function, and contributing to protein synthesis and bone strength. Although some studies have produced mixed results regarding the benefits of magnesium supplements, most experts agree that obtaining this mineral from whole foods is ideal.
However, it is important to note that purslane contains high levels of oxalates, naturally occurring substances found in many plants and produced by our bodies as well. In excessive amounts, oxalates can bind with minerals like calcium and iron in the digestive tract, limiting their absorption and potentially contributing to the formation of kidney stones. Individuals who are prone to kidney stones or who have high levels of oxalates in their urine should consider consulting with a healthcare provider before incorporating significant amounts of purslane into their diet.
Whether enjoyed raw or cooked, purslane’s slightly tangy flavor makes it a delightful addition to salads, sandwiches, quiches, and various other dishes. It can be blended into pesto or soups, or added to stir-fries and grilled vegetables as a flavorful garnish. Beyond its culinary versatility, purslane is an exceptional garden plant due to its ability to thrive in challenging conditions, including dry soil, salinity, and nutrient-poor environments. It flourishes best in full sunlight—requiring six to eight hours of light daily—and although it is an annual plant that cannot survive frost, it rewards gardeners with its robust, low-maintenance growth during the warmer months.
Ultimately, purslane is not only a testament to nature’s resilience but also a rich source of nutrition and health benefits that have been appreciated across centuries and cultures.
