The purslane plant (Portulaca Oleracea) is one of those herbs that sometimes you just can’t decide whether to keep or remove from your garden. It’s often viewed as unwelcome because it pops up beside plants you want to showcase or eat. Purslane has become so widespread in gardens1 today that the U.S. Department of Agriculture has branded it a noxious weed.2
Purslane, which may reach up to 30 centimeters (11 to 12 inches) high, can grow in almost any place, as long as there is loose, sandy and nutrient-rich soil. You can find it in gardens, roads, fields or orchards.3 The plant has a green or red stem,4 spoon-like succulent leaves5 and small flowers with a distinct yellow color. On hot and sunny days, the buds usually open from midmorning until early afternoon.6
But is purslane edible? It surely is. This herb is widely embraced in certain cuisines as a wonderful addition to salads and other recipes.7 In the U.S., however, it’s still seen as an unwelcome plant.8
Remember that if you remove this herb from your garden, you may be casting aside the numerous health benefits that it can actually offer you. In fact, purslane may be called a “superfood” because of the vitamins and minerals that can be found in this herb.9
Owning up to its title as a “superfood,” purslane has a wide variety of vitamins and minerals in its arsenal. It has antibacterial, antiscorbutic (combats scurvy10), depurative (detoxifying and purifying11), diuretic (increases amount of fluids expelled from the body12) and febrifuge (fever-reducing13) properties.14 Plus, you can also receive these beneficial nutrients when you consume purslane:
• High amounts of omega-3 fatty acids15— The leaves of the purslane plant are abundant in omega-3 fatty acids that may help prevent high cholesterol and blood pressure levels and aid in lowering the risk for heart disease and, possibly, cancer.16 Omega-3 fats also have anti-inflammatory abilities, and they may help manage cognitive function17 and promote normal growth and development.18
• Minerals like zinc, phosphorus, manganese, copper and calcium19— Zinc is responsible for maintaining and improving immune system function,20 and combating free radicals that may cause inflammation and cancer.21,22 Calcium is also essential for nerve, muscle and blood function,23 and in promoting optimal bone24 and dental health.25
The copper in purslane can help ensure absorption of iron from your intestines, and assist with hemoglobin production in your body.26 Lastly, manganese acts as an antioxidant27 and helps fight off free radicals.28,29 It’s also useful in breaking down fats, protein and carbs to use as energy by your body.30
• Vitamin A — Compared to other leafy vegetables, purslane contains the highest amounts of vitamin A,31 which may be beneficial for improving and maintaining visual health32,33 and cell growth.34 Vitamin A has also been linked to better bone health, although you may need to consume it in moderation to reap this benefit — some studies revealed that too much vitamin A may lead to adverse effects, such as increased fracture risks.35,36
• Low in calories — Purslane contains only 20 calories per 100 grams.37 This is good news if you’re trying to limit your caloric intake. It’s also packed with dietary fiber,38 which helps you feel full after meals, limit your food intake39 and aid in weight loss.40,41
Purslane can actually be used in different ways to help relieve illnesses such as headaches,42 fever and inflammation, to name a few.43 Purslane, when made into a juice, may also be used as a remedy for dry cough and shortness of breath.44
The 16th century English botanist Nicholas Culpeper also claimed that purslane leaves can be placed under the tongue to quench thirst,45 though I would still recommend drinking enough high-quality filtered water to address dehydration.
Aside from these medicinal purposes, purslane can be added to salads, soups, omelets,46 stews, casseroles and tomato sauces.47 The stems and leaves have a crunchy texture and mild flavor,48 which is reminiscent of spinach or watercress.49
Purslane can be propagated in two ways: through purslane seeds or plant cuttings.50 Tiny purslane seeds, which can be reddish brown to black, can be found in small pods51 that appear in the spring or summer.52 When the seeds become mature, the pods burst and are released into the surroundings.53 The purslane seeds usually take roughly three to seven days to germinate when exposed to temperatures between 70 and 90 degrees Fahrenheit.54
Purslane plants can thrive anywhere, even indoors.55 Here are tips on how to successfully cultivate purslane plants indoors by using seeds, courtesy of the website Garden Guides:56
- Acquire seeds. You can buy purslane seeds online or get them from scattered plants. If you choose to gather seeds from wild purslane, make sure the plants haven’t been treated with pesticides or herbicides.
- Fill a pot with rich soil. You can also add soil from your compost bin as a fertilizer. When planting purslane seeds, make sure that you scatter them evenly on top of the soil. Use your fingers to gently rake the soil and cover the seeds.
- Make sure that you water the soil until it’s moist. While the purslane plant is germinating, moisten the soil every day. Avoid watering the soil to the point that it gets too soggy.
- Place the pot in a location where it can get enough sunlight. Purslane seeds need light to germinate.57 They usually take about two weeks to sprout.
A reminder on purslane plant care: It can become invasive,58 more so if you don’t plant it properly. It’s recommended that you harvest a purslane plant before the flowers appear since the stems may feel tougher afterward.59 Since purslane grows annually, you may need to acquire seeds or stems from your present plants60 to make sure your supply doesn’t run out.
Purslane can be eaten either raw or cooked.61 The plant’s young leaves and stems are the parts most often consumed.62 If you’re planning on eating raw purslane, make sure the plant is pesticide- and herbicide-free to prevent ingestion of harmful chemicals such as the weed killer, Roundup. As a precaution, wash purslane (no matter what part you use) thoroughly before consuming.63
You can also cook purslane, and there are numerous ways to incorporate this herb into your favorite dishes, cooked or raw. You can boil it in water for 10 minutes, drain afterward64 and eat it alone, add it raw to salads or other recipes for an added crunch,65 or mix into your recipes for soups, omelets,66 stews, casseroles and tomato sauces.67 Just make sure to avoid overcooking purslane, or it can become slimy.68
Even though most people don’t know that purslane is a nutritious herb, recipes have started to crop up with it as the main ingredient. This means the herb is starting to gain popularity, and people are becoming aware of its potential in improving human health.
