Purslane: Powerful Health Benefits, Nutrition, and Uses
A tangy, nutrient-rich green that elevates everything from salads to smoothies.
What Is Purslane?
Purslane (Portulaca oleracea) is often considered a common weed but stands out as a powerhouse nutritious leafy vegetable with a rich history in traditional medicine and global cuisines. With fleshy, succulent leaves and a slightly tangy taste, it’s recognized for its dense nutritional value, medicinal properties, and versatility in food preparation.
Purslane has gained the reputation of being the “reigning champion” of vitamins A and E among edible plants, and is widely appreciated for its safety and adaptability to various dishes.
Nutritional Value of Purslane
Purslane’s outstanding nutrition profile is what truly sets it apart among greens. Its leaves and stems deliver a high concentration of vital nutrients, making it a functional food in both modern and traditional diets.
| Nutrient | Amount per 1 cup (43g raw) | % Daily Value (DV) |
|---|---|---|
| Calories | 7–10 | – |
| Protein | 0.5–1g | – |
| Fat | 0.1g | – |
| Carbohydrates | 1–1.5g | – |
| Fiber | 0.6g | – |
| Vitamin A | 10% DV | High |
| Vitamin C | 20% DV | High |
| Vitamin E | 10% DV | High |
| Potassium | 10% DV | High |
| Iron | 5% DV | Decent |
| Magnesium | High | – |
| Folate | High | – |
| Omega-3 Fatty Acids | ~400mg | Highest among leafy greens |
Purslane’s omega-3 levels rival those found in some fish, making it a crucial plant-based source for heart and brain health. It also contains secondary metabolites like flavonoids, alkaloids, polysaccharides, melatonin, and glutathione, which function as strong antioxidants and cellular protectors.
Top Health Benefits of Purslane
Purslane’s broad spectrum of nutrients delivers numerous health advantages, including:
- Omega-3 Fatty Acids: Purslane leads all land-based plants in omega-3 content (especially alpha-linolenic acid). These essential fats aid in lowering inflammation, supporting cardiovascular wellness, and reducing risk of heart disease, stroke, and dementia.
- Rich Antioxidants: High in vitamins A, C, E, beta carotene, melatonin, glutathione, and flavonoids. These help mitigate oxidative stress, slow aging, and strengthen immune function.
- Bone Health: Notable for its calcium and magnesium content, which together support strong bones, dental health, and help prevent osteoporosis. Magnesium also controls hormones for effective calcium utilization in the body.
- Diabetes and Blood Sugar Control: Emerging research finds purslane can lower fasting blood sugar, making it potentially helpful for people managing type 2 diabetes or with higher body mass index. It may support weight regulation and metabolic health.
- Anti-cancer Properties: The abundance of flavonoids, alkaloids, and polysaccharides shows early promise against certain cancers by supporting cellular health and inhibiting malignant growths. Continued research is needed.
- Digestive and Gut Health: Its fiber content aids in gut regularity, feeds beneficial microbiota, and reduces risks of gastrointestinal distress or constipation.
- Hydration and Electrolytes: High water content and electrolyte richness support optimal hydration, muscle function, and overall well-being.
- Wound Healing and Immunomodulation: Purslane’s natural compounds can support wound healing, liver health, and may combat bacterial, viral, and yeast infections according to early studies.
Why Should You Eat Purslane?
Purslane is a unique, nutrient-dense green suitable for most diets due to its low calories, minimal sugar, and substantial vitamins and minerals. The global recognition of purslane in culinary traditions highlights its taste, versatility, and ability to boost mineral intake. Its vitamin A and E levels far exceed those found in common vegetables like tomatoes, broccoli, and lettuce—offering up to 9–12 times more vitamin A than commonly consumed greens. Purslane also contains norepinephrine and organic acids that are rarely present in edible plants, contributing to its functional food status.
How to Use Purslane in Cooking
Purslane is a versatile edible with a slightly sour and peppery flavor that complements many recipes. Both leaves and stems are suitable for culinary use. Some popular ways to add purslane to your meals include:
- Raw in Salads: Adds crunch and a tangy kick. Pair with olive oil, cucumbers, tomatoes, and fresh herbs for a refreshing salad.
- Sandwiches, Wraps, and Smoothies: Use leaves as a vegetable in wraps or blend them into smoothies for increased nutrition.
- Cooked: Toss into soups, stews, and stir-fries alongside other greens. Brief cooking preserves its texture and nutrient density.
- Traditional Dishes: Purslane appears in Mediterranean, Asian, and Mexican cuisines, from egg-based dishes to savory sauces and rice.
- Soups and Sautéed Dishes: Quickly sauté with garlic, onions, and spices for a nutritious side.

Tips for Choosing and Storing Purslane
- Choose purslane with firm stems and vibrant, fleshy leaves.
- Wash thoroughly to remove dirt and potential contaminants.
- Store in the refrigerator wrapped in a moist towel to preserve freshness for up to a week.
- If wild-harvesting, ensure plants are collected from organic, uncontaminated areas.
Potential Risks and Precautions of Purslane
While purslane is broadly considered safe for most, certain individuals should exercise caution:
- Oxalate Content: Purslane contains moderate oxalates—chemicals that can contribute to kidney stone formation in susceptible people. This risk is higher in seeds than leaves or stems, so it is best avoided by those with a history of kidney stones or related urinary tract issues.
- Sodium Levels: Due to its succulent texture, purslane can be saltier than other greens. Moderate intake is recommended for those on sodium-restricted diets to prevent excessive salt consumption.
- Digestive Upset: Some people may experience mild gastrointestinal effects (such as bloating or discomfort) when first introducing high-fiber purslane to their diet. Start with small portions.
- Contaminant Absorption: Purslane easily absorbs pollutants from the soil. Always source it from clean environments, preferably certified organic farms, to avoid heavy metals or chemical contamination.
- Pregnancy and Nursing: Limited research exists on purslane’s safety for pregnant and lactating women. Consult with your healthcare provider prior to consumption if you are pregnant or breastfeeding.
- Nonalcoholic Fatty Liver Disease: Research is mixed; consult a doctor before introducing purslane if you have this condition.
Purslane Compared to Other Leafy Greens

| Lettuce | Moderate | Minimal | Beta carotene | 5–10 |
| Spinach | High | Some | Lutein, zeaxanthin | 7 |
| Broccoli | Low | Minimal | Vitamin C, sulforaphane | 31 |
Purslane’s extraordinary vitamin A and omega-3 content distinguish it from other common leafy greens, with the added bonus of unique antioxidants.
