Helichrysum Italicum Essential Oil (Immortelle Essential Oil)
This profile pertains specifically to Helichrysum Essential Oil that has been steam distilled from the species Helichrysum italicum / Helichrysum angustifolia.
Helichrysum Essential Oil is also sometimes known as Everlasting Essential Oil or Immortelle Essential Oil.
Helichrysum Essential Oil is widely appreciated for its potent anti-inflammatory benefits.
Helichrysum Essential Oil is the only commercially available essential oil that contains several diketones known as italidiones. Italidiones make up only a small percentage of the total composition of Helichrysum Essential Oil, but they are said to be largely responsible for the anti-inflammatory action. Essential oils steam distilled from other Helichrysum species do not contain italidiones. For more information about the composition of Helichrysum Italicum Oil, see the Major Constituents section further down on this page.
Helichrysum Essential Oil distilled from plants grown in Corsica tend to be preferred. Regardless of the country of origin, I recommend taking a close look at the composition of the oil as there can be big differences in the composition of the oil, even when only comparing oils sourced from Corsica.
When most sellers and people refer to Helichrysum oil, they are typically referring to the essential oil that is steam distilled from the species Helichrysum italicum. However, there are several other oils available distilled from other varieties of Helichrysum, particularly Helichrysum bracteiferum, Helichrysum gymnocephalum and Helichrysum splendidum. Each species of Helichrysum Essential Oil has very different aromatic and therapeutic properties, so it's important to ensure that you doublecheck the botanical name of the oil that you are working with.
Steffen Arctander describes the aroma of Helichrysum Oil as being "...powerful and diffusive, but pleasant and rich, common with those of the extracted material (everlasting absolute), and these topnotes are not exactly attractive at high concentration. The sweetness is so rich and overwhelming, honeylike and deep, that it takes more than the average of imagination to appreciate the odor of this oil. However, the sweet-fruity and tea-like, delicate undertone is unique, and the tenacity is quite outstanding." I personally find it hard to fully describe the aroma of Helichrysum, and find that Arctander's description does the aroma justice. [Reference: Steffen Arctander, Perfume and Flavor Materials of Natural Origin (Reprint Edition. Elizabeth, NJ: Pathfinder., 2017), 291.]
When I first smelled Helichrysum Essential Oil twenty years ago, I had a powerful emotional reaction and flashback. I haven't had that same type of encounter with any other essential oil as when I first smelled Helichrysum, but it still gives me goosebumps when I recall that experience. It was a very enlightening moment that was bittersweet yet simultaneously comforting and reassuring. I never had that same powerful emotional reaction again, but I have found Helichrysum to be a wonderful oil for use during meditation, reflection and self growth.
Joni Keim Loughran and Ruah Bull say that "This powerful essential oil grounds us in Divine love and guidance, fostering understanding an compassionate insight." [Reference: Joni Keim Loughran and Ruah Bull, Aromatherapy Anointing Oils (Berkeley, CA: Frog, Ltd., 2001), 52.]

From the ranges I have personally seen, Helichrysum Italicum Essential Oil lots from reputable sellers tend to have approximately 25-30% Neryl Acetate, 4-6% Italidiones, 6-12% Gamma Curcumene, and <3% a-Pinene. However, this should not be treated as a definitive guideline.
Dr. Robert Pappas of Essential Oil University has shared that "Chemically the best [Helichrysum italicum] oil will be fairly high in neryl acetate low in alpha-pinene and have healthy levels of italidiones..."
Robert Tisserand indicates that the ranges of the key components present in Helichrysum Italicum Essential Oil tend to fall within the below ranges:
- Neryl Acetate: 6-40%
- a-Pinene: 3-30%
- Gamma-Curcumene: 8-15%
- Italidiones: 3-10%
