Immortelle is a small silvery shrub from the Mediterranean with clusters of yellow flower heads. Crushed leaves smell like curry powder, which is why it is also called the curry plant. It is not the curry spice blend used in cooking, and it is not a food herb.
Most products use the flowers. They are steam-distilled into an essential oil, or soaked in a carrier oil to make an infused oil. These are sold mainly for skin care, bruises and minor scrapes.
Here is the honest verdict. Human evidence is very thin, and most research is lab or animal work. Long folk use is not proof that it works, and it is not proof that it is safe.
The plant is known as smilje in Croatia and as elihryso in Greece. Croatian and Corsican oils are the best known on the market. Quality and strength vary a lot between brands.
Nobody has shown clearly how immortelle acts on human skin. The ideas below come from test tubes and animals, not from people.
In laboratory tests, extracts slow some bacteria and fungi. Whether that happens on real skin at the strengths people use is not established.
In cell and animal studies, a compound called arzanol appears to damp down signals that drive swelling. Animal work also suggests the oil may speed repair of small skin wounds. These results have not been confirmed in good human trials.
The traditional claim that it clears bruises faster rests on the idea that it helps the body reabsorb trapped blood. That idea has not been tested properly in people.
You will most often meet it as one of these:
- Essential oil, steam-distilled from the flowers. Very concentrated and costly. - Infused or macerated oil, where flowers are soaked in a carrier oil.
Much weaker. - Creams, balms and serums for face and body. - Hydrosol, the scented water left after distilling.
Used as a face spray. - Dried flowers for tea, mostly in southern Europe. - Tinctures, which are alcohol extracts.
Skin products are by far the most common use. Teas and tinctures are a smaller folk tradition and are poorly studied.
Immortelle has a long record in Mediterranean folk use, chiefly in Croatia, Corsica, Italy, Greece and Spain. The name means "everlasting", because the dried flowers keep their colour and shape for years.
Village practice treated it mainly as a skin and wound herb. Crushed flowers or oil were put on bruises, sprains, burns and small cuts. Some regions also brewed the flowers for coughs and chest complaints, or burned them as a smoke.
The essential oil is a modern product. Commercial distilling grew in Corsica and the Balkans during the twentieth century, and the oil became a costly cosmetic ingredient.
This section records what people did. It is not a suggestion that you copy it.
Stop using it and see a doctor if:
- A rash spreads, blisters, or keeps getting worse after you stop. - A wound turns red, swollen, warm or oozes pus. - You get a fever with a skin problem. - A bruise appears for no clear reason, or does not fade over two weeks. - A skin complaint has not improved after two weeks of use.
Get emergency help if your lips, face or throat swell, or you have trouble breathing. Call poison control at once if anyone swallows the essential oil.
In the EU and UK it is sold as a cosmetic ingredient and a food flavouring, not as a licensed medicine. In the United States it is sold as a cosmetic or a dietary supplement, and no health claim for it is approved by the FDA.
