Everlasting is a small, grey-leaved shrub of the Mediterranean coast. It grows on sand dunes and dry, stony ground. The dried yellow flower heads are the part people use.
In Portugal it is called perpétua-das-areias. In Spain it is known as manzanilla de campo. Both names point to its old use as a field "chamomile" tea.
Folk users brewed the flowers for coughs, colds and an upset stomach. They also used washes of the tea on sore skin.
Here is the honest verdict. Human evidence is very thin, and no trial shows that it treats any illness. Long folk use is not proof that it works, and it is not proof that it is safe.
No one has shown how this plant acts in the human body. Everything below comes from the laboratory, not from patients.
In test-tube work, flower extracts mop up free radicals (damaging molecules). In cell studies, some of its compounds lower markers of swelling.
In lab tests, extracts slow the growth of certain bacteria and fungi. Whether that happens on real skin, or in the gut, has not been shown.
Tradition treated the tea as a way to loosen chest mucus and settle the stomach. Those effects have not been tested in people.
So the short answer is simple. The lab findings are interesting, but they do not tell you what a cup of the tea will do.
Most people meet it as dried flowers for tea. Products are rarely standardised, so strength varies between brands.
Dried flower heads, sold loose by weight.
Tea bags for an infusion.
Liquid extracts and tinctures made with alcohol.
Essential oil, distilled from the flowers. Shops more often stock oil from the related plant Helichrysum italicum.
Creams, balms and skin oils that list the plant as one ingredient.
One safety point about the oil. The essential oil is for skin or scent use only. Do not swallow it.
European folk medicine in Portugal, Spain, southern France and Italy used these flowers for centuries. Country people picked them from dunes and dry hillsides in summer.
The flowers were brewed as a tea for coughs, colds and stomach complaints. Cooled tea was dabbed on grazes, boils and sore eyes. Some households used it as a mild bitter after heavy food.
The dried heads keep their colour for years, which is how the plant earned its name. They were laid in linen chests to repel moths, and used in dried bouquets.
These records tell you what people did. They do not tell you whether it worked.
Stop at once and get emergency help if your lips, tongue or throat swell, or if you struggle to breathe. These can be signs of a severe allergic reaction.
Stop and book a doctor if you get a rash, hives or stomach pain that does not settle.
See a doctor rather than treating yourself if a cough lasts more than three weeks, you cough up blood, you run a fever, or you feel breathless.
Also seek care if your skin or eyes turn yellow, or your urine turns dark.
In the European Union it is sold as a herbal tea, a food supplement and a cosmetic ingredient. It has no approved medicine status and no European Medicines Agency monograph.
In the United States it is sold as a dietary supplement. The FDA has not approved it to treat any condition.
