Essential oils, called volatile oils or ethereal oils, are natural metabolic secretions of plants, the role of which is not yet fully understood by science. Some specialists consider them to be true plant hormones, fluid manifestations of the immune system of plants, in the sense that they contribute to the removal of pests, attracting, instead, pollinating agents, which are some insects and birds. Small, light–colored spherical structures, is, in fact, modified filaments, which behave like some secretory glands of essential volatile oils. They are the ones who give the fragrance of the aromatic plant and have, in the case of salvation, medicinal curative properties, such as fever reduction, blood cleansing, and relieving pain. Essential oils are products isolated from plants or organs through a physical process that have a certain volatility (higher or lower) and possesses an agreeable odour characteristic of the source from which they originate. They are also known as volatile or essential oils and their name are usually given by the popular name of the plant from which they are extracted. The most important characteristic of these mixtures, which also gives the special economic value, is the specific smell. This is the basis for their use in perfumery, cosmetics and the food industry. Many essential oils have special therapeutic qualities, some of which have been known and used since antiquity.

Antifungal antagonism of different fourteen plant essential oils was examined as natural agents against economic and hygienic effective three yeasts; the preservative efficacy of most potent anti-yeast essential oil in food sanitary was also tested. Study involved oils antifungal bioactivity screening against Saccharomycescerevisiae, Candida albicans,and Candida utilis. Study also included selection and invitro extraction of most bioactive oil, and evaluation of its antifungal minimal inhibitory concentrations (MICs). Control ofjuice spoilage by Saccharomycescerevisiae under the effect of in vitro oil extract different concentrations was also screened. Among the tested essential oils, apricot seed oil was the most bioactive anti-yeast agent. Two MIC values of apricot oil invitro extract, 12.5μgml-1 and 25μgml-1 were recorded. In juice samples, oil extract bioactivity increased gradually up to concentration 100μgml-1.Highest oil preservative ability was observed at oil concentration of and above 125μgml-1. Higher oil concentrations needed for juice preservation were found more than in vitro assay to give the same effect. Applying of apricot oil and some other plant essential oils could be used as an environmental safety mode in osmophilic food preservation and in Candidate diseases biocontrol.

The incidence rate of melasma is notably high among patients with anxiety disorders. Aromatherapy primarily influences the physiological and psychological states of individuals through the inhalation or application of essential oils, thereby facilitating the treatment or alleviation of various conditions. This study aims to explore the action mechanism of complex lemon-angelica sinensis -boswellia essential oil (CEO) in treating anxiety disorders with melasma. We investigated the active ingredients, targets, and pathways of CEO in relation to anxiety and melasma using network pharmacology. We employed cell assays and conducted nebulized essential oil inhalation tests on CUMS mice to validate the intervention effects of CEO on anxiety. A total of 28 active components, including neryl acetate, 3-butenylphthalide and octyl acetate, and 26 cross-targets, such as ESR1, CCND1 and PIK3CA, were identified. GO and KEGG pathway analyses indicated that these cross-targets were primarily involved in endocrine regulation, cell proliferation, and apoptosis, specifically through PI3K/Akt signaling pathway and calcium signaling pathway. The experimental results demonstrated that CEO significantly reduced the secretion of NO, TNF-a and IL-6, as well as the mRNA expressions of ESR1, CCND1 and PIK3CA in cells compared to the inflammatory cell model. Furthermore, CEO notably decreased the forced swimming immobility time of mice and the levels of IL-1β, ESR1 and CCND1 in hippocampus when compared to model mice. These findings suggest that CEO may regulate ESR1, CCND1 and PIK3CA through its citral, 3-butylphthalate and neryl acetate, thereby influencing endocrine function, cell proliferation and apoptosis, inhibiting inflammation and anxiety-like behavior in CUMS-induced mice.

Coriander, commonly known as Sabit dhania in Pakistan is a well-known spice used in traditional cooking. It is an essential component of ayurvedic medicine used for the treatment of digestion and gastric ailments. Coriander seeds are available throughout the year as whole seeds and in powdered form. Fresh Coriander seeds possess earthy bitter flavour with strong aroma. Essential oils of its seed extracts possess numerous valuable constituents which could be exploited for the preparation of medicinal combatants against several acute and chronic diseases.
