- Etymology: Species name bracteatum derives from Latin referring to the papery bracts of the flower heads, which are mistakenly called petals. Xerochrysum is derived from Greek words xeros meaning dry, and chrysum meaning golden. (20)
- Taxonomy: The golden everlasting was described by French botanist Etienne Pierre Ventenat in his 1803 work Jardin de Malmaison.
In 1805 Henry Cranke Andrews transferred it to the genus Helichrysum based on the morphology of its receptacle, and was known as Helichrysum bracteatum for many years. It was briefly designated as Bracteantha bracteata in 1991, until 2002 when it took the name Xerochrysum bracteatum. (20)
Everlasting is a stout annual herb
growing to a height of 30 to 60 centimeters , with terete and sparingly branched
stems. Leaves are alternate, oblong-lanceolate, with entire margins,
and narrowed at the base. Blade is green on both sides. Flower head
is terminal, up to 6 centimeters across, golden yellow, pink, orange to ivory
white, enclosed by strawlike imbricated bracts of varying colors of
red, yellow, brown and white.
Thrives best in the
high altitudes, i.e., Baguio and Tagaytay.
- Native range: Australasia
and New Zealand.

• Study of anthocyanins in the petals of H. bracteatum flower with deep purple color obtained a pure anthocyanin chloride crystal, identified as a cyanin glucoside by IR, UV, and MS techniques. (15)
• Considered anti-inflammatory, antimicrobial, antispasmodic, antitussive, astringent, diuretic, expectorant, fungicidal, cicatrisant, liver stimulant.
• Studies have suggested
hepatoprotective, anti-inflammatory, analgesic, anticancer, antiviral, acaricidal properties.
Flowers, aerial parts.
- No reported folkloric
use in the Philippines.
- Plant used for wound dressing.
• Decorative: A
favorite decorative or altar flower, as it lasts indefinitely when dried.
• Repellent: Scentless when fresh, but said to repel moths when dried.
• Oil: Oil used to flavor tobacco and as fixative in perfume and cosmetics.
• Gamma-pyrone: A
2007 study yielded a new gamma- pyrone, sterols and triterpenes from
H. bracteatum. Of seven compounds isolated, 4 were from aerial parts,
3 from flowers. Gamma-pyrone compounds were considered potential anti-cancer
• Anti-Inflammatory / Hepatoprotective:
Study yielded four flavones, five flavonols, six caffeoyl derivatives
of quinic acid from the flowers and aerial parts of Helichrysum bracteatum.
The flavonol bractein was the most potent anti-inflammatory
and antipyretic and the flavonol 3,5-dicaffreoylquinic acid was the
most potent analgesic. The flowers showed significant hepatoprotective
• Acaricidal / Leaves: Study evaluated the acaricidal activity of Helichrysum bracteatum and Salvia officinalis against Tetranycus urticae and its predator Stethorus gilvifrons adult females in measures of egg laying capacity, repellent and oviposition deterrent effects.
H. bracteatum 70% ethanol leaf extract showed highest acaricidal activity with LC50 1.27%. Both extracts showed potent ovicidal effect. GC-MS analysis revealed phytol to be the major component of the Hb extract. Results confirmed potent acaricidal effect of both leaf extracts against T. urticae (12)
• Anti-Inflammatory / Effect on UVB-Irradiation Induced Inflammatory Biomarkers / Flowers: Study evaluated the anti-inflammatory activity of flower extracts in vitro. The DPPH assay showed the flower extracts have good antioxidative effects and inhibited the expression of inflammation-related genes TNF-α, IL-6, and COX-2. The production of NO and TNF-α was inhibited by the flower extracts. Results showed the flower extracts have efficacy against UVB-induced inflammation-related gene expression. (13)
• Natural Dyes / Antimicrobial / / Flowers: Study evaluated Helichrysum bracteatum flowers as a plant source for dyeing textile materials. Two major flavonoids were isolated: bractein and cernuoside. Various intensities of color shades for fabrics and acceptable fastness properties were obtained. Samples showed remarkable antimicrobial activity against E. coli, P. vulgaris, and S. typhi, with linear increase in zone of inhibition with increasing concentrations. (see constituents above) (14)
• Y-Pyrone / Mild Anticancer and Anti-Viral Activity / Aerial Parts: Study of aerial parts isolated a new Y-pyrone, 3-ethyl-6-(7'-hydroxy-7'-methyl-nonyl)-2-methoxy-5-methyl-pyran-4-one (helichrysone) (3), along with α-amyrin, stigmasterol, spinasterol, oleanolic acid, and glycoside 4 and 7. Compound 3 showed mild activity against cervix and breast cancer cell lines in vitro as well as mild anti-HIV activity. (16)
• Carbohydrates / Sugar Content / Flowers: Chromatographic study for qualitative composition and sugar contents of H. bracteatum flowers yielded 12 sugars among bound carbohydrates and 13 compounds among the free. Significant amounts of sugars were found in flowers among specific monosaccharides glucose, fucose, and sucrose; in the herb, xylose, glucose, and sucrose.
Study indicates a rather diverse and rich content of sugars in herbal drugs of immortelle. (17)
