Immortelle Drug Interactions, Uses, Safety & More

Immortelle is a small flowering plant in the daisy family that grows in the Mediterranean and parts of Europe and Asia. It is also called everlasting or helichrysum because its bright yellow flowers keep their color even after they are dried. The name Helichrysum arenarium refers to one common species, while a closely related plant, Helichrysum italicum, is often used to make essential oil.

People have used immortelle for many years in folk medicine. The dried flowers are made into teas and tinctures, and the plant is also distilled into an essential oil used in skin care and aromatherapy. It is most often taken for digestion, liver and gallbladder complaints, and skin or wound care.

Immortelle is traditionally used for digestive upset, liver and gallbladder support, mild inflammation, coughs, and skin problems. Much of what we know comes from traditional use, laboratory studies, and animal research rather than large, well-designed human trials.

Test-tube studies suggest the plant contains compounds with antioxidant and anti-inflammatory activity, and some lab work has looked at antimicrobial effects. However, good-quality human studies are lacking, so we cannot say with confidence that immortelle treats or cures any health condition. If you choose to try it, think of it as a traditional remedy and do not use it to replace proven medical care.

Immortelle contains plant compounds such as flavonoids (including arzanol and related substances), phenolic acids, and aromatic oils. In laboratory studies, these compounds appear to act as antioxidants, meaning they may help neutralize unstable molecules called free radicals.

Some lab and animal research also suggests the plant may calm certain inflammation signals and may have mild effects against bacteria and fungi. It is important to remember that these are mostly early, non-human findings. They do not prove the herb will have the same effects in people who take it as a tea or supplement.

Immortelle has a long history of use as a food and tea, and in those amounts it is generally considered well tolerated by most healthy adults. Still, high-quality safety data for concentrated supplements and extracts is limited.

Because immortelle is in the daisy (Asteraceae) family, people allergic to ragweed, chrysanthemums, marigolds, or similar plants may react to it. Pregnant and breastfeeding people should avoid it because there is not enough information to know it is safe. People with liver or gallbladder disease should check with a doctor before using it, since the herb is traditionally used to affect bile flow. The essential oil should never be swallowed and should be diluted before being applied to the skin.

When used as a tea or in food amounts, immortelle does not commonly cause serious side effects in healthy adults. Possible reactions include allergic skin reactions, rash, or stomach upset, especially in people sensitive to plants in the daisy family.

Concentrated extracts and essential oil carry more risk. Undiluted essential oil can irritate the skin, and essential oils should not be taken by mouth. Stop using immortelle and seek medical care if you notice signs of an allergic reaction such as swelling, trouble breathing, or a widespread rash.

There is no official, standardized dose of immortelle. Traditional use involves brewing the dried flowers as a tea or using a tincture, but the amount of active compounds can vary a lot between products.

If you use a commercial supplement, follow the directions on the product label and do not exceed them. Because strength and quality differ between brands, it is best to ask your pharmacist or doctor before starting, especially if you take other medicines or have a health condition. Essential oil is for external or aromatherapy use only and must be diluted.
