Pussley is a low, sprawling garden weed that people eat as a green. Its botanical name is Portulaca oleracea. Across the Caribbean it is also called purslane, pourpier or verdolaga.
The leaves and stems are thick and juicy. They taste mildly sour and a little salty. Cooks add them to soups, stews, rice dishes and salads, and the seeds are eaten too.
In Caribbean home medicine it was used for the stomach and bowels, for passing water, and on sore or burned skin. It was also valued simply as cheap, nourishing food.
Here is the honest verdict. As a vegetable, purslane is safe and nutritious for most people. As a medicine, human proof is thin for every claim made about it.
Traditional use tells you people valued the plant. It is not proof that it works, and it is not proof that it is safe for everyone.
No one has shown how purslane works in the human body. Most claims rest on lab dishes and animal work.
Purslane is unusually rich in alpha-linolenic acid, a plant omega-3 fat. Diets higher in plant omega-3 fats are linked with better heart health. Purslane supplies a useful amount for a leafy green.
In cell and animal studies, purslane extracts appear to lower blood sugar and to calm inflammation. Animal work also points to an antioxidant effect. Whether any of that happens at food amounts in people is not established.
The leaves hold a slimy fibre called mucilage. In theory this softens stool and coats an irritated gut lining. That is a reasonable idea, not a tested one.
Purslane is also high in potassium. Folk reports describe a mild water-pill (diuretic) effect, meaning more urine. Human trials have not confirmed this.
Most people meet purslane as a vegetable, not a product.
Common forms are:
- Fresh leaves and stems, raw in salads or cooked in soups and stews. - Fresh juice from the crushed plant. - Dried leaf, brewed as a tea.
- Mashed fresh leaves used as a poultice on the skin. - Seeds, whole or ground into a powder. - Capsules or tablets of dried leaf or seed powder.
- Liquid extracts and tinctures, sold online.
Food use and supplement use are not the same thing. A plate of cooked greens gives a modest amount. A daily extract gives a concentrated dose that has not been tested well in people.
Product quality varies. Purslane supplements are not checked the way medicines are, so strength and purity can differ between brands.
Caribbean households grew purslane, or let it grow, and treated it as both food and remedy. Haitian and Dominican cooks knew it as pourpier. In Cuba and the Dominican Republic it is verdolaga.
Folk healers used mashed fresh leaves on burns, boils, stings and sore eyes. Tea from the leaves and stems was taken for upset stomach, constipation and burning urine. Seeds were given for worms in some islands.
The plant is not only Caribbean. It spread with people across Africa, Europe, the Middle East and Asia. It appears in Ayurvedic practice and in Chinese herbal medicine as ma chi xian.
In hard times it was eaten as a free green that grew anywhere. Records of these uses come from cookbooks, oral accounts and old herbal texts.
Stop and see a doctor if you get pain in your side or back, blood in your urine, or pain when passing water. These can be signs of a kidney stone or an infection.
Get urgent help if you have swelling of the lips, face or throat, a widespread rash, or trouble breathing after taking it.
See your doctor promptly if you feel shaky, sweaty, confused or faint, which can mean low blood sugar (hypoglycaemia). Also seek care for muscle weakness or an irregular heartbeat (arrhythmia), which can point to high potassium.
If a skin problem you are treating is spreading, oozing or not better in a few days, have it looked at.
In the United States, the United Kingdom, the European Union and across the Caribbean, purslane is an ordinary food plant and may be sold and eaten freely. Capsules and extracts are sold as food supplements, not as medicines, so they are not approved to treat or prevent any disease.
