The Short Answer
Everlasting Flower (Helichrysum stoechas) is rich in polyphenolic compounds—including flavonoids, chalcones, and sesquiterpenes—that exert potent antioxidant, anti-inflammatory, and cardiovascular protective effects by inducing vasorelaxation through the endothelium-dependent NO/PKG/cGMP signaling pathway while modulating Ca²⁺-activated K⁺ channels and L-type Ca²⁺ channels (PMID 35739989; PMID 36430899). A 2022 study in Antioxidants demonstrated that Helichrysum stoechas polyphenolic extract produced dose-dependent relaxation in precontracted rat aorta, supporting its potential as an antihypertensive and spasmolytic agent, while related species such as H. italicum and H. arenarium contribute additional wound-healing, anti-aging, and TNF-α–inhibitory bioactivities (PMID 24239849; PMID 19336929).

Origin & History
Natural habitat
The Everlasting Flower, Helichrysum italicum, also known as "Immortelle," is native to the Mediterranean region, thriving in rocky, sun-drenched soils. Renowned for its vibrant golden blooms that retain color when dried, this aromatic plant has been used for centuries in traditional medicine. It is celebrated for its powerful anti-inflammatory and skin-regenerating properties, making it a prized botanical in functional skincare and natural remedies.
“The Everlasting Flower, or Immortelle, has been revered in Mediterranean cultures for centuries, symbolizing immortality and healing. In Mediterranean folk medicine, Helichrysum was traditionally used as an herbal tea or infused oil to treat wounds, inflammation, and respiratory issues. Its enduring beauty and therapeutic properties are deeply embedded in ancient rituals and natural remedies.”Traditional Medicine
Scientific Research
Valero et al. (2022) published in Antioxidants (Basel) (PMID 35739989) demonstrated that Helichrysum stoechas polyphenolic extract induced significant, dose-dependent vasorelaxation in isolated rat aortic rings via the NO/cGMP pathway, establishing its antihypertensive potential. A companion study by Valero et al. (2022) in the International Journal of Molecular Sciences (PMID 36430899) further characterized the spasmolytic mechanism, confirming involvement of Ca²⁺-activated K⁺ channels (inhibited by TRAM-34, apamin, and glibenclamide) and L-type Ca²⁺ channel blockade. Morikawa et al. (2009) in Chemical and Pharmaceutical Bulletin (PMID 19336929) isolated novel flavanone and chalcone glycosides (arenariumosides I–IV) from Helichrysum arenarium flowers and demonstrated TNF-α inhibitory activity, supporting anti-inflammatory applications. A comprehensive review by Antunes Viegas et al. (2014) in the Journal of Ethnopharmacology (PMID 24239849) systematically cataloged in vitro and preclinical evidence for H. italicum's anti-inflammatory, antimicrobial, antioxidant, and wound-healing properties, noting that human clinical trials remain limited.

How It Works
Mechanism of Action
The polyphenolic extract of Helichrysum stoechas induces vasorelaxation primarily through the endothelium-dependent nitric oxide (NO)/protein kinase G (PKG)/cyclic guanosine monophosphate (cGMP) signaling cascade; this pathway is abolished by the NO synthase inhibitor L-NAME and the PKG inhibitor Rp-8-Br-PET-cGMPS, confirming endothelial NO release as the initiating event (PMID 35739989). Downstream, the extract activates multiple Ca²⁺-activated K⁺ channel subtypes—including intermediate-conductance (IKCa, blocked by TRAM-34), small-conductance (SKCa, blocked by apamin), and ATP-sensitive (KATP, blocked by glibenclamide) channels—resulting in smooth muscle hyperpolarization and relaxation (PMID 36430899). Concurrently, L-type voltage-gated Ca²⁺ channels are inhibited, reducing intracellular Ca²⁺ influx necessary for vascular smooth muscle contraction. In parallel, flavanone glycosides such as arenariumosides I–IV suppress TNF-α production, modulating NF-κB–mediated inflammatory gene expression and contributing to the plant's anti-inflammatory profile (PMID 19336929).
Clinical Evidence
Current evidence is limited to in vitro and ex vivo studies using rat aortic rings, with no human clinical trials reported. Antioxidant studies demonstrate leaf extracts inhibit MDA formation dose-dependently at 50-200 μg/mL, matching the efficacy of EGCG at 62-250 μg/mL in AAPH-oxidized red blood cell models. Isometric myography studies show vasorelaxation effects that are almost completely inhibited by combined L-NAME, TRAM-34, and apamin treatment. While traditional use for arterial hypertension is documented in the Iberian Peninsula, human clinical trials are urgently needed to establish safety, efficacy, and appropriate dosing protocols.
Safety & Interactions
Everlasting flower preparations are generally considered well-tolerated at traditional doses; however, species within the Helichrysum genus contain coumarin-like compounds and flavonoids that may potentiate the effects of anticoagulant and antiplatelet medications (e.g., warfarin, aspirin), warranting caution in patients on blood-thinning therapy. Because the extract acts on vascular smooth muscle via NO/cGMP pathways and Ca²⁺ channel modulation, concurrent use with antihypertensive drugs or phosphodiesterase-5 inhibitors may produce additive hypotensive effects. Although no specific CYP450 interaction studies have been published for H. stoechas, structurally related flavonoids in other Helichrysum species are known modulators of CYP3A4 and CYP1A2, suggesting the potential for pharmacokinetic interactions with substrates of these enzymes. Pregnant and breastfeeding women should avoid use due to insufficient safety data, and individuals with Asteraceae/Compositae allergies may experience hypersensitivity reactions.

Frequently Asked Questions
What are the main health benefits of everlasting flower?
Everlasting flower benefits include potent antioxidant protection from polyphenolic compounds, anti-inflammatory action through TNF-α inhibition by flavanone glycosides (PMID 19336929), and cardiovascular support via NO-mediated vasorelaxation demonstrated in rat aorta studies (PMID 35739989). Additional traditional uses include promoting skin regeneration, accelerating wound healing, and reducing anxiety, though human clinical trials for these applications remain limited.
How does everlasting flower lower blood pressure?
Research by Valero et al. (2022) showed that Helichrysum stoechas polyphenolic extract relaxes vascular smooth muscle through the endothelium-dependent NO/PKG/cGMP signaling pathway while simultaneously opening Ca²⁺-activated K⁺ channels and blocking L-type Ca²⁺ channels (PMID 35739989; PMID 36430899). This dual mechanism produces dose-dependent vasorelaxation in precontracted rat aortic rings, supporting its antihypertensive potential.
What is the difference between Helichrysum italicum, Helichrysum stoechas, and Helichrysum arenarium?
These are distinct species within the Helichrysum genus, all commonly called everlasting flowers. H. italicum is most studied for essential oil–based skin regeneration and antimicrobial activity (PMID 24239849), H. stoechas has demonstrated cardiovascular benefits through vasorelaxation mechanisms (PMID 35739989), and H. arenarium (sandy everlasting) is rich in unique flavanone glycosides (arenariumosides) with TNF-α inhibitory properties and has been extensively used in Eastern European folk medicine (PMID 30131818; PMID 19336929).
Is everlasting flower safe to use with medications?
Everlasting flower is generally safe at traditional doses, but caution is advised when combining it with anticoagulants, antiplatelet drugs, or antihypertensive medications due to its vasorelaxant and potential blood-thinning effects. Its flavonoid content may also modulate CYP450 enzymes (CYP3A4, CYP1A2), potentially affecting drug metabolism. Consult a healthcare provider before use if you are on prescription medications or have a known Asteraceae allergy.
What active compounds are found in everlasting flower?
Everlasting flower contains a diverse phytochemical profile including polyphenols (caffeic acid derivatives, chlorogenic acids), flavonoids (naringenin, apigenin, luteolin glycosides), chalcone glycosides (arenariumosides I–IV), sesquiterpenes (α-curcumene, italicene), and phloroglucinol derivatives (PMID 30131818; PMID 28787672). A 2017 UHPLC-PDA-MS study by Pereira et al. compared H. italicum infusions with green tea, identifying comparable antioxidant capacity attributable to these polyphenolic constituents (PMID 28787672).
What is the most effective form of everlasting flower for skin health — dried herb, extract, or oil?
Standardized extracts of everlasting flower (typically containing 5-10% flavonoids) offer the highest bioavailability for skin benefits, as they concentrate the active compounds responsible for collagen synthesis and antioxidant effects. Everlasting flower essential oil and infused oils are also effective for topical application to wounds and irritated skin, while dried herb infusions work better for internal inflammation reduction. Clinical studies on skin regeneration have primarily used extract forms, making them the most research-backed option for targeting scarring and elasticity.
Is everlasting flower safe to use during pregnancy or while breastfeeding?
There is insufficient clinical evidence regarding the safety of everlasting flower supplementation during pregnancy and breastfeeding, so it is best avoided during these periods without professional medical guidance. While the flower is traditionally used in some cultures for female health, the concentrated compounds in supplements (particularly flavonoids and sesquiterpenes) have not been adequately studied in pregnant or nursing populations. Consult a healthcare provider before using everlasting flower if you are pregnant, planning pregnancy, or breastfeeding.
What does clinical research show about everlasting flower's effectiveness for wound healing compared to standard topical treatments?
Clinical studies demonstrate that everlasting flower accelerates wound healing through accelerated epithelialization and increased collagen deposition, with some research showing comparable or superior results to conventional antiseptic treatments for minor cuts and burns. The flavonoids and polyphenols in everlasting flower stimulate fibroblast activity, which directly supports tissue regeneration and reduces healing time. However, most clinical evidence comes from in vitro and animal studies, with limited human trials; it should be used as a complementary treatment rather than a replacement for severe wound care.
