Helichrysum Oil
Also known as: Helichrysum italicum (Roth) G. Don, Immortelle, Italian strawflower, Curry plant, Helichrysum italicum
Overview
Helichrysum italicum, a perennial shrub native to the Mediterranean, is the source of helichrysum oil, extracted from its flowering tops and leaves. This essential oil is traditionally used topically for pain, inflammation, and wound healing, and, in some systems, internally for pain, cough, and mental exhaustion. The oil is characterized by its anti-inflammatory, antimicrobial, and antioxidant properties, attributed to its chemical composition, including neryl acetate, α-pinene, and γ-curcumene. While preclinical studies show promise, clinical evidence is limited, with most data stemming from small, heterogeneous trials. The quality of available evidence is further constrained by small sample sizes, a lack of robust randomized controlled trials (RCTs), and variability in formulations and indications, highlighting the need for more rigorous research to validate its therapeutic potential.
Benefits
Clinical evidence supporting the benefits of Helichrysum italicum is limited. A small study (n=15) suggested that topical application of helichrysum oil, when mixed with coconut oil, may reduce knee pain after 30 days of use, but not after 15 days. However, this finding lacks confirmation from larger, well-controlled RCTs. Preclinical studies indicate potential antimicrobial and anti-inflammatory effects, but these have not been consistently translated to clinical settings. Currently, there is no robust evidence to support specific benefits for particular populations. The clinical significance of observed effects remains unclear due to the limited data and methodological constraints of available studies.
How it works
The proposed mechanisms of action for Helichrysum italicum involve several biological pathways. It is thought to inhibit inflammatory cytokines, exert antioxidant activity, and modulate pain pathways. The oil's effects may influence both the immune and nervous systems through its anti-inflammatory and analgesic properties. While the specific molecular targets are not fully understood, it is believed that terpenes and flavonoids within the oil interact with inflammatory mediators. Absorption and bioavailability, particularly for oral or topical use, are not well-characterized, though essential oils are generally absorbed through the skin or mucous membranes.
Side effects
Helichrysum italicum is generally considered safe for topical use, with limited data available on internal use. Clinical studies have not reported common, uncommon, or rare side effects. However, due to the lack of comprehensive data, caution is advised. There are no documented drug interactions, but potential interactions cannot be ruled out. Contraindications are not well-established, but individuals with known allergies should avoid its use. There is a lack of safety data for specific populations, including pregnant or breastfeeding women, children, and immunocompromised individuals, necessitating caution in these groups.
Dosage
Due to limited clinical data, a minimum effective dose and maximum safe dose of Helichrysum italicum have not been established. For topical applications, a 2-5% dilution in a carrier oil is typically recommended. Oral use is not standardized and not generally recommended due to a lack of supporting data. Topical application can be considered 1-2 times daily. Essential oils are lipophilic, suggesting potential absorption through the skin, but the extent of absorption has not been quantified. No specific cofactors are identified as required for its use.
FAQs
What is Helichrysum oil typically used for?
Helichrysum oil is primarily used topically for its potential pain-relieving and anti-inflammatory properties. Internal use is less common and not as well-supported by research.
Is Helichrysum oil safe to use?
Topical use is generally considered safe. However, internal use should be approached with caution due to limited safety data. Always perform a patch test before widespread topical application.
How quickly can I expect to see results?
Some studies suggest modest pain reduction after prolonged topical use (e.g., 30 days). Effects are not immediate and may vary from person to person.
Can Helichrysum oil cure any medical conditions?
No, Helichrysum oil is not a proven cure for any condition. Its benefits are modest and not universally supported by high-quality evidence. It should be used as a complementary therapy.
How should Helichrysum oil be applied?
For topical use, dilute the essential oil in a carrier oil (like coconut or jojoba) to a 2-5% concentration. Apply to the affected area 1-2 times daily. Avoid ingestion unless under professional supervision.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC8399527/ – This systematic review examined the internal use of Helichrysum italicum, finding no robust evidence for efficacy across various indications like pain, cough, and mental exhaustion due to small, heterogeneous trials. The review highlighted a favorable safety profile but noted the low to moderate quality of evidence due to methodological limitations and a lack of large randomized controlled trials.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC11350649/ – This systematic review focused on the antibacterial and antifungal potential of Helichrysum italicum, primarily based on preclinical studies. The review demonstrated antimicrobial and antifungal activity in vitro, but emphasized that the clinical relevance remains unclear due to the absence of human clinical trials.
- https://www.proquest.com/scholarly-journals/review-evaluation-data-supporting-internal-use/docview/2565514742/se-2 – This review and evaluation of data supporting the internal use of Helichrysum italicum highlights the limited evidence available. It points out the heterogeneity of existing studies and the lack of robust data to support its efficacy for various conditions. The review emphasizes the need for more rigorous research to validate its potential benefits and safety.
- https://www.mdpi.com/2304-8158/12/4/802 – This study likely explores the chemical composition and potential biological activities of Helichrysum italicum. It likely details the presence of various terpenes and other compounds contributing to its anti-inflammatory and antioxidant properties. Further investigation into the specific mechanisms of action and clinical applications of these compounds is warranted.
- https://archives.palarch.nl/index.php/jae/article/download/1442/1470/2809 – This clinical study investigated the effects of topical Helichrysum oil on knee arthritis in a small group of adults. The study found significant pain reduction after 30 days of topical application, but not at 15 days. The study's limitations include a small sample size, lack of a control group, and subjective pain assessment, resulting in a low quality of evidence.
