“…This latter effect was found to sensitivity between methicillin-resistant S. aureus and methicillin-sensitive S. aureus strains (Nostro et al, 2001). Furthermore, it was also showed that the diethyl ether extract at sub-minimum inhibitory concentrations (sub-MIC) reduced the activity of S. aureus enzymes, specifically DNAse, lipase, thermonuclease and coagulase (Nostro et al, 2001). Sub-MIC concentrations of the extract also compromised S. aureus ability to produce the enterotoxins B and C (Nostro et al, 2002).…”

This characteristic also allows H. italicum to grow at a wide range of altitudes, between the sea level and 2200 m Nostro et al, 2001;Perrini et al, 2009), and assumes particular relevance under an economic perspective.…”

“…Some studies highlight the terpenoid fraction (Mastelic et al, 2005) while others suggest that these activities might be due to both terpenes and flavonoids (Nostro et al, 2001;Nostro et al, 2002). However, the ability of terpenes and flavonoids to interact with the cytoplasmatic membrane of S. aureus and induce its structural and functional destabilization highlights their prominent role in the antibacterial activity demonstrated by H. italicum (Nostro et al, 2001;Nostro et al, 2000).…”

Ethnopharmacological relevanceHelichrysum italicum (Roth) G. Don fil. (family Asteraceae) has been used for its medicinal properties for a long time and, even nowadays, continues to play an important role in the traditional medicine of Mediterranean countries. Based on this traditional knowledge, its different pharmacological activities have been the focus of active research. Aim of the reviewTo provide an overview of the current state of knowledge of the pharmacological activities of H. italicum, as well as its traditional uses, toxicity, drug interactions and safety. Materials and methodsThe selection of relevant data was made through a search using the keywords "Helichrysum italicum" and "H. italicum" in "Directory of Open Access Journals", "Google Scholar", "ISI Web of Knowledge", "PubMed", "ScienceDirect" and "Wiley Online Library". Information obtained in local and foreign books and other sources was also included. ResultsThere are reports on the traditional use of H. italicum in European countries, particularly Italy, Spain, Portugal and Bosnia and Herzegovina. In these countries, its flowers and leaves are the most used parts in the treatment of health disorders such as allergies, colds, cough, skin, liver and gallbladder disorders, inflammation, infections and sleeplessness. In order to validate some of the traditional uses of H. italicum italicum in vivo activity, the highlight goes to the anti-erythematous and photoprotective activities of its flavonoids, demonstrated both in animals and humans, and to the anti-inflammatory properties exhibited by its flavonoids, acetophenones and phloroglucinols, as seen in animal models. Concerning its safety and adverse effects, while H. italicum does not display significant levels of cytotoxicity or genotoxicity, it should be noticed that one of its flavonoids inhibited some CYP isoforms and a case has been reported of an allergic reaction to its extracts.

“…It has been effective against bacteria and fungi that can cause skin irritations, infections and delay wound healing. A very strong hematoma-dissolving effect makes immortelle oil one of the best effective oils in treatment of hematomas [26]. In one study a contact toxicity test was performed with six essential oils (Achillea millefolium, Myrtus communis, Rosmarinus officinalis, H. italicum, Foeniculum vulgare and Lavandula angustifolia) against the stored food insect Sitophilus zeamais Motsch.…”

Essential Oils and Their Single Compounds in Cosmetics—A Critical Review

2018

View full text Add to dashboard Cite

Essential oils are widely incorporated in cosmetic products, perfumes and related household products due to the variety of their properties but mainly due to their pleasant odour. The composition of these volatile natural complex mixtures may vary depending on the quality of plant material from which they were obtained and the extraction method by which they were derived. These factors are also important in ensuring the safe use of essential oils in personal care products. As they contain compounds with varied chemical structure and effects, skin sensitivity and irritations as well as other symptoms may arise after their application. Although essential oils are considered as safe and nontoxic when used at low concentrations, available scientific literature indicates that essential oils and their compounds may possess a strong allergy potential. This review focuses on side effects and allergy contact dermatitis caused by selected essential oils and their single compounds in cosmetic products, summarizing data from the most recent scientific literature.

Composition of Helichrysum italicum subsp. italicum essential oil showed chemical variability according to vegetation cycle, environment, and geographic origins. In the present work, 48 individuals of this plant at different development stages and the corresponding root soils were sampled: i) 28 volatile components were identified and measured in essential oil by using GC and GC/MS; ii) ten elements from plants and soils have been estimated using colorimetry in continuous flux, flame atomic absorption spectrometry, or emission spectrometry (FAAS/FAES); iii) texture and acidity (real and potential) of soil samples were also reported. Relationships between the essential-oil composition, the inorganic plant composition, and the soil characteristics (inorganic composition, texture, and acidity) have been established using multivariate analysis such as Principal Component Analysis (PCA) and partial Redundancy Analysis (RDA). This study demonstrates a high level of intraspecific differences in oil composition due to environmental factors and, more particularly, soil characteristics.
