Purslane (Portulaca Oleracea): The Weed with Many Benefits

Purslane (also known as common purslane, verdolaga, red root, pursley or portulaca oleracea) is an edible plant that is packed full of nutrients, vitamins, and minerals. Although purslane is referred to as a weed, this succulent broadleaf plant has many health benefits. Eating purslane leaves can help to improve digestion, strengthen your immune system, and promote good heart health. You can also use purslane as a topical remedy for irritated skin and help wounds heal faster.

Many people are surprised that purslane weed can be so good for you that it is considered as a beneficial herb. Studies have shown that purslane contains antimicrobial, antidiabetic, and anti-inflammatory properties. This herbaceous succulent plant is used in cooking, salads, and traditional medicine for its many health benefits.


Although purslane is a healthy edible “weed”, you have to take care when picking the plant. Hairy-stemmed spurge is a poisonous plant that looks like purslane. Also, due to its oxalate levels, purslane may not be good if you are at risk of having kidney stones.

In this article, you will learn about the many science-based reasons to add purslane leaves to your diet. You will find out how to use this succulent weed to address a number of health issues.

Purslane (Portulaca Oleracea) is a Weed with Many Benefits

Purslane (Portulaca oleracea) is a common annual plant that thrives in warm, dry climates. Researchers say that the common purslane has succulent foliage and yellow blossoms when it flowers. (1)

Other names for purslane plant include verdolaga, pursley, or red root.

The edible leaves of the purslane plant are oval-shaped and can grow up to just over an inch long (3 cm). Purslane leaves can be eaten raw in salads or cooked in soups, stews or other dishes to give them a crunchy texture.

Some people say that purslane plant leaves taste similar to spinach or watercress.

Purslane vs. hairy-stemmed spurge

One of the reasons to grow your own purslane plant in your backyard is to prevent confusing it with hairy-stemmed spurge.

Hairy stemmed spurge has been described as a purslane poisonous look alike. Spurge plants contain a milky sap that is a contact irritant.

How can you tell the difference between purslane and spurge? Scientists say that the leaves and stems of hairy-stemmed spurge are not a succulent as purslane leaves. Also, purslane doesn’t excrete a milky-white sap when the leaves or stems are broken. (2)

What is it about purslane weed that makes it so healthy?

The United States Department of Agriculture reports that a 1-oz. (28 g) serving of purslane only contains 6 calories and 1 gram of carbs. This serving of purslane has almost 6 g of vitamin C which is 10% of your recommended daily intake. Purslane leaves also contain vitamin A and B-group vitamins. (3)

More of the nutritional benefits of purslane come from minerals. Studies have shown that purslane is a good source of potassium, magnesium, and calcium. These are important minerals for your blood pressure, a healthy heart, and having strong bones. (4, 5)

One of the health benefits of purslane is the fact that it is a good source of plant-based omega-3 fatty acids. Purslane contains ALA (alpha-linolenic acid) omega-3 which researchers say is necessary for good health and disease prevention. (6)

In order to fully benefit from taking purslane, some people use purslane supplements that come as powder (like this one), capsules (like this one) and tincture. These supplements can be found in health stores or online and contain all the antioxidants such as ascorbic acid, carotenoids, and omega-3 that is found in purslane leaf.

One of the precautions with eating a lot of purslane is its oxalate content. A diet rich in vegetables with high oxalate content such as spinach and purslane can increase your risk of kidney stones. High levels of oxalates can also affect mineral absorption. (7, 8)

    Can you can or freeze this for later use?

    • Jenny Hills, Nutritionist and Medical Writer says:

  12. Ali says:

    Purslane, along with some other herbs & spices is apparently great for helping to cleanse the lymphatic system. Clogged & congested lymph is at the root of so many of our modern diseases these days. If it cannot remove cellular metabolic wastes properly, aid metabolism of various substances & food elements, nor transport nutrients from the gut to the bloodstream very well, we are in trouble. Whilst Ayurvedic & Chinese medicine focus a lot on cleansing the lymph & interstitium, it’s not even on the conventional medicine radar.

  13. Mariam Wilson says:

    Can the leaves be dried for future use? Same q for stems. Thanx!

    • Jenny Hills, Nutritionist and Medical Writer says:

      I have never tried to dry the plant but I’ve seen in the internet people who dried the leaves/stems in dehydrator rack, or on a cookie rack if drying in the oven.

  14. Martha Parisi says:

    I used to have loads of these, starting just a couple of years ago, that must’ve come from bird poop or seeds in the wind bc I have never grown this. I tried my best to pull every single one out and by last year I had pretty much eradicated them (bc I thought they hogged water away from my veggies). This year, I saw a video about purslane and was amazed at what I used to throw away. But, I didn’t have anymore and thought, oh well. Well, wouldn’t u know 1 popped up out of nowhere and I argued with myself whether to leave it or not. I decided to leave it and figured I could harvest a lot for salads if need be (after-all it was just 1 plant). Well, as u may’ve guessed, I have a veggie garden full of them now. Right back where I started a couple of years ago. Mine don’t seem to spread-out like most pictures show – they have 1 stem of just get very big – like 6″ tall and more.

    Being tho I can’t pluck off stems and leave the roots, do I have to pull out each one roots-and-all and just rely on having many plants popping-up??

    • Jenny Hills, Nutritionist and Medical Writer says:

      Purslane is an annual plant, although in tropical and warm areas (USDA zones 10-11) it is a perennial. If you live in a cooler areas, then the plant life cycle will be one year (annual). After flowering, the flowers are replaced by a seed capsule. The capsules will split open, releasing the seeds, and then you will have new plants. In addition to reseeding itself, you can propagate by stem cuttings and placing them in the soil. These stems will produce roots and you’ll have new plants.
