“…The MIC values of M. communis oil were found to be 50 μ L/mL for A. flavus and 30 μ L/mL for A. ochraceus and F. culmorum [45]. In addition, Bouzabata et al [87] analyzed the antifungal activity of M. communis oil against E. floccosum , Microsporum canis , Trichophyton rubrum (dermatophytes), and Cryptococcus neoformans (yeast). An MIC value of 0.64 mg/mL was found to be lethal for M. canis , T. rubrum, and E. floccosum .…”

A wide range of medicinal and aromatic plants (MAPs) have been explored for their essential oils in the past few decades. Essential oils are complex volatile compounds, synthesized naturally in different plant parts during the process of secondary metabolism. Essential oils have great potential in the field of biomedicine as they effectively destroy several bacterial, fungal, and viral pathogens. The presence of different types of aldehydes, phenolics, terpenes, and other antimicrobial compounds means that the essential oils are effective against a diverse range of pathogens. The reactivity of essential oil depends upon the nature, composition, and orientation of its functional groups. The aim of this article is to review the antimicrobial potential of essential oils secreted from MAPs and their possible mechanisms of action against human pathogens. This comprehensive review will benefit researchers who wish to explore the potential of essential oils in the development of novel broad-spectrum key molecules against a broad range of drug-resistant pathogenic microbes.

“…The oils showed significant anti‐inflammatory activity and are safe at concentrations up to 0.64 mg/ml for macrophages and at concentrations up to 1.25 mg/ml for keratinocytes, hepatocytes, and alveolar epithelial cells. Bioactive concentrations of myrtle essential oils with a safety profile were disclosed in this study indicating a potential topical and oral application or its use by inhalation .…”

The genus Myrtus L. (Myrtaceae family) comprises two species, Myrtus communis L. (known as common myrtle) growing wild all around the Mediterranean basin and Myrtus nivellei Batt. and Trab. (known as Saharan myrtle), found in central Sahara. Only one country, Algeria, hosts both species, M. communis in the North and M. nivellei in the South. The aim of this review was to collect, summarize, and compare the main results reported relative to the essential oils isolated from aerial parts of both species: botanical aspects, habitat, traditional use, chemical composition, new compounds, antimicrobial activity, antioxidant activity, anti-inflammatory effect, and insecticidal activity. Both essential oils have potential applications in human health.

As the personal care industry evolves, formulators are seeking innovative solutions for their formulations' needs, and for ingredients that can offer multiple functions within formulations. Considering that essential oils (EOs) may present a wide spectrum of biological activities, the composition, antimicrobial and antioxidant activity of Portuguese Thymbra capitata, Thymus caespititius and Myrtus communis EOs were assessed in order to evaluate them as preservatives and antioxidants in topical emulsions. The in vivo safety application of some emulsions was also tested. T. capitata EO was mainly constituted by carvacrol (73%), whereas α‐terpineol (27%), p‐cymene (14%) and carvacrol (10%) dominated Th. caespititius EO, and 1,8‐cineole (37%) was dominant in M. communis EO. The minimum inhibitory concentration of T. capitata, Th. caespititius and M. communis EOs was 0.4 μg/mL against C. albicans and ranged between 0.4 and 30.7 μg/mL against A. brasiliensis. Gram‐positive bacteria were more susceptible to each EO than Gram‐negative bacteria. T. capitata EO showed significantly higher antioxidant activity than Th. caespititius and M. communis EOs. EOs incorporated in emulsions showed preservative activity against all microorganisms tested and T. capitata EO emulsions showed powerful reactive oxygen species (ROS) scavenging effects. A safety evaluation study was performed with 0.10% and 0.01% T. capitata EO emulsions according to the Human Repeat Insult Patch Test (HRIPT). All emulsions were considered safe for topical application. T. capitata, Th. caespititius and M. communis significantly improved the microbiological quality of the prepared emulsions and may constitute a powerful alternative to the current preservatives and antioxidants for use in topical formulations.
