Effects of eggshell powder emulsion gel on the oxidative stability and sustained-release effect of lavender essential oil

This study aimed to develop a new type of eggshell powder (EP) emulsion gels for improving the antioxidant ability and sustained release effect of lavender essential oil (LEO). The effects of EP addition on the physicochemical, structural properties, oxidative stability, and sustained-release performance of the emulsion gels were investigated. The results showed that with the increase of EP addition (0–1 %), the gel strength initially increased and then decreased. The emulsion gel with 1 % EP had better freeze-thaw stability (36.77 %), thermal stability (78.63 °C), and water holding capacity (96.57 %). Moreover, the micromorphology results indicated that the EP-ovalbumin (OVA)-konjac glucomannan (KGM) complex showed a connected filamentous network structure, and the emulsion gel with 1 % EP addition had the most uniform and densest network structure. Furthermore, the EP emulsion gel had the highest free sulfhydryl content and hydrophobic interaction, and LEO exhibited the best antioxidant and sustained-release properties at this time. In conclusion, the findings demonstrated the potential of eggshell powder to enhance emulsion gel stability, which could improve the high-value utilization of egg by-products.

Effect of Lavender Essential Oil Topical Treatment on the Autonomic Nervous System in Human Subjects Without Olfactory Influence: A Pilot Study

Objective/background As part of a scientific study into the effects of aromatherapy, we investigated the effects of lavender essential oil (LEO) treatment on the autonomic nervous system in subjects for whom the sense of smell had been eliminated. Methods This study used a single-blinded cross-over design for verification. Heart rate variability was measured and effects on the autonomic nervous system were investigated. Results and discussion Although no significant differences were found, aromatherapy treatment with 1% LEO tended to increase parasympathetic nervous system activity. Further, when differences between values before and during aromatherapy treatment were compared, LEO treatment significantly increased parasympathetic nervous system activity. Given these findings, LEO appears to increase parasympathetic nervous system activity, even in the absence of a psychological effect due to an absence of olfactory stimulation. Conclusion The present results provide a scientific method for verifying the effects of aromatherapy and will aid in further elucidation of aromatherapy.

Lavandula angustifolia Essential Oil Inhibits the Ability of Fusobacterium nucleatum to Produce Volatile Sulfide Compounds, a Key Components in Oral Malodor.

Oral malodor still constitutes a major challenge worldwide. A strong effort is invested in eliminating volatile sulfur compound-producing oral bacteria through organic natural products such as essential oils. Fusobacterium nucleatum is a known volatile sulfur compound-producing bacteria that inspires oral malodor. The aim of the present study was to test the effect of lavender essential oil on the bacterium's ability to produce volatile sulfide compounds, the principal components of oral malodor. Lavender (Lavandula angustifolia) essential oil was extracted by hydrodistillation and analyzed using GC-MS. The minimal inhibitory concentration (MIC) of lavender essential oil on Fusobacterium nucleatum was determined in a previous trial. Fusobacterium nucleatum was incubated anaerobically in the presence of sub-MIC, MIC, and above MIC concentrations of lavender essential oil, as well as saline and chlorhexidine as negative and positive controls, respectively. Following incubation, volatile sulfur compound levels were measured using GC (Oralchroma), and bacterial cell membrane damage was studied using fluorescence microscopy. Chemical analysis of lavender essential oil yielded five main components, with camphor being the most abundant, accounting for nearly one-third of the total lavender essential oil volume. The MIC (4 µL/mL) of lavender essential oil reduced volatile sulfur compound secretion at a statistically significant level compared to the control (saline). Furthermore, the level of volatile sulfur compound production attributed to 1 MIC of lavender essential oil was in the range of the positive control chlorhexidine with no significant difference. When examining bacterial membrane damage, 2 MIC of lavender essential oil (i.e., 8 µL/mL) demonstrated the same, showing antibacterial membrane damage values comparative to chlorhexidine. Since lavender essential oil was found to be highly effective in hindering volatile sulfur compound production by Fusobacterium nucleatum through the induction of bacterial cell membrane damage, the results suggest that lavender essential oil may be a suitable alternative to conventional chemical-based anti-malodor agents.

Effect of Lavender Aromatherapy on Anxiety and Fatigue in Hemodialysis Patients: A Systematic Review and Meta-Analysis.

Several studies have evaluated the effects of lavender essential oil on the anxiety of hemodialysis (HD) patients, but most of them did not estimate the pooled effect size. The current systematic review and meta-analysis was conducted to evaluate the effects of lavender on anxiety and fatigue among HD patients. Eligible studies were selected based on the PRISMA steps and protocol. Literature was retrieved from PubMed, Web of Science, Scopus databases, Cochrane, ClinicalTrials.gov, and Google Scholar Search Engines until Sep 2022. The risk of bias and analysis were evaluated using version 2 of the Cochrane risk-of-bias tool and STATA v.14 software, respectively. Effect sizes were pooled using random effect models. Nine studies were included. Lavender oil significantly reduced the average anxiety of HD patients compared to the control group (SMD: -2.51, 95% CI: [-3.56, -1.45], Z=4.67, P<0.001, I2 :89.9%). Also, it significantly reduced the average fatigue compared to the control group (SMD: -1.56, 95% CI: [-2.49, -0.63], Z=3.29, P=0.001, I2:92.2%). Subgroup analysis indicated controversial results regarding session frequency and drop number of lavender oil. Using Lavender oil significantly reduced fatigue and anxiety in HD patients.

The Effect of Lavender Essential Oil on Escherichia coli Growth and its Potential Applications

Escherichia coli (E. coli) infects millions worldwide annually, leading to thousands of deaths, particularly impacting those low to middle-income countries where E. coli can be found in contaminated soil, water, and surfaces (Winstead et al. 2019). In this investigation, lavender essential oil and ampicillin disks were tested against E. coli grown on an agar plate to see if they could be used as a potential antimicrobial agent in regions where E. coli infections are largely prevalent. Based on the Kirby-Bauer tests conducted in this investigation, lavender essential oil displayed a clear zone of inhibition, though it was relatively smaller than the zone of inhibition for ampicillin. Future applications to such findings could be to utilize lavender in both plant and essential oil form as a treatment for E. coli soil contaminations and a natural pest repellent, both in the agricultural industry and in regions where cost-effective, environmentally sustainable treatments may not currently exist.

Impact of essential oils on seed quality and seed-borne pathogens of Altheaofficinalis seeds of different ages

BackgroundThe cultivation of medicinal plants is a promising alternative to overcoming problems in the overharvesting of wild plants and ecosystem degradation. Cultivation depends upon two major factors: seed quality and the presence of seed-borne pathogens. Organic production of marshmallow plants (Altheaofficinalis L.) does not allow for the use of conventional pesticides. This study aimed to find an environmentally safe solution and the equilibrium between seed germination and the presence of fungal pathogens. The study was performed on a population of marshmallows which were cultivated for a period of 3 years (2018–2020) in Pančevo, The Republic of Serbia. The following six essential oils: Origanumvulgare L.,Cinnamomumcassia Presl.,Ocimumbasilicum L.,Carumcarvi L.,Menthapiperita L.,Lavandulaangustifolia Mill. at five concentrations (1%, 0.5%, 0.2%, 0.02%, 0.002%) were used for seed treatment along with water and PEG-40 (emulsifier) as controls. Germination, dormant seeds, dead seeds, abnormal seedlings and the presence of seed-borne pathogens were determined under laboratory conditions.ResultsAmong the aforementioned treatments using oregano, cinnamon, basil, caraway, mint, and lavender essential oils, the most effective treatment resulted with lavender essential oil at a concentration of 0.02% in 3-year-old seeds. The highest values for seed germination and dead seeds were 46% and 20% in 3-year-old seeds, respectively. This treatment increased seed germination by 13%, and seedling growth i.e., the growth of seedling stems and radicles by 24–35%, respectively. It also reduced the presence of seed-borne fungal pathogens from 53 to 100%.ConclusionsThe results revealed that an increase in seed germination rate and simultaneous reduction in seed-borne fungal infection was achieved with the lavender essential oil seed treatments. This is the first discovery of the stimulating effect of lavender essential oil on seed quality parameters. Furthermore, the study demonstrates its potential application in seed processing in the organic production of marshmallow plants.Graphical

A new solution for control of respiratory infection by Streptococcus equi isolated from horses in northern Iran

Respiratory infections caused by Streptococcus equi are one of the most important diseases in the equine industry. The increasing rate of antibiotic resistance among this bacterial species necessitates new antimicrobial agents. In this research, nasopharyngeal samples were taken from horses (n=90) in some areas of the Golestan Province, Iran. After isolation and identification of S. equi strains, antibiotic resistance of the isolates was evaluated using the Kirby-Bauer method. The antibacterial effect of lavender essential oil was investigated by broth microdilution assay. The frequency of streptococcal strains was 27.8%. The most frequent isolates were S. equi subsp. equi (72%) and S. equi subsp. zooepidemicus (28%). The frequency of S. equi was highest in horses aged less than 2 years (69.3%) and thoroughbred Turkmen horses (61.5%). The highest rate of resistance was observed against amoxicillin, while the highest rate of sensitivity was to ceftriaxone. Furthermore, the essential oil of lavender inhibited 90% of the isolates at concentrations ≥2048 μL/mL. Our study revealed that the frequency of antibiotic-resistant S. equi isolates was relatively high in the studied population of horses in Iran. It was concluded that essential oil of lavender possessed more potent in vitro activity than the common antibiotics for treatment of infections caused by S. equi subspecies.

Lavender essential oil fractions alleviate sleep disorders induced by the combination of anxiety and caffeine in mice

Ethnopharmacological relevanceLavender (Lavandula angustifolia Mill.) essential oil is renowned for its use in the treatment of insomnia and mental disorder diseases in folk medicine. Previous pharmacological studies have also shown that lavender essential oil displays sedative and hypnotic activities. However, the active ingredients and mechanism of lavender essential oil for sleep-improving effect remain unclear. Aim of the studyThis study investigates whether inhalation of different fractions of lavender essential oil can attenuate the sleep disturbances induced by combined anxiety and caffeine and explores the underlying mechanisms. Materials and methodsMolecular distillation was applied to separate lavender essential oil into fractions containing different chemical components, and GC-MS was used to analyze the volatile compounds of lavender essential oil and its fractions. The elevated plus maze test, pentobarbital-induced sleep test, and neurotransmitters enzyme-linked immunosorbent assay were conducted to evaluate the anxiolytic and hypnotic effects of lavender essential oil and its fractions on mice suffering from sleep disorders. ResultsThe results of behavioral tests indicated that lavender essential oil and its fractions (3%, v/v) exerted an ameliorating effect on sleep disturbances induced by anxiety and caffeine. The light fraction and heavy fractions exhibited complementary chemical composition, with the former enriched in linalool and trans-β-ocimene and the latter in linalyl acetate, lavandulyl acetate, trans-caryophyllene, etc. The light fraction contributed more to sleep maintenance, and the heavy fraction performed better at sleep initiation. The neurobiological parameters elucidated that the mechanism of lavender essential oil for sleep-improving was multifaceted, related to the GABAergic system, cholinergic system, histaminergic system, and monoamines in the limbic system. The heavy fraction shared a similar mechanism with the lavender essential oil, while the light fraction did not actively participate in the cholinergic system, histaminergic system, and dopaminergic system. ConclusionTaken together, our results demonstrated that different fractions of lavender essential oil played different roles in ameliorating sleep disorders, and this may be credited to their compositional differences and the complicated interactions with the central nervous system. The results are informative for future investigations on the molecular level mechanisms and provide guidance for appropriate applications of lavender essential oil.

The elimination effects of lavender essential oil on Listeria monocytogenes biofilms developed at different temperatures and the induction of VBNC state.

Listeria monocytogenes is a typical foodborne pathogen that causes hard-to-treat bacterial infections, mainly due to its ability to form biofilm and enter into a viable but non-culturable state (VBNC). In this study, we investigated the removal effects of four antimicrobial agents on L. monocytogenes biofilms formed at 32°C and 10°C, analysed the resistances of the mature biofilms to antimicrobial agents, and explored the VBNC state of cells in mature biofilms induced by lavender essential oil (LEO). The results showed that the growth of L. monocytogenes was completely inhibited when 1·6% (v/v) of the LEO was added. Meanwhile, the results of the crystal violet staining and XTT reduction method indicated that different concentrations of LEO significantly reduced L. monocytogenes biofilms biomass and metabolic activities, followed by sodium hypochlorite, lactic acid, and hydrogen peroxide. Moreover, the confocal laser scanning microscopy (CLSM) images confirmed that the treated biofilms became thinner, the structure was sparse, and the appearance was blurry. More interestingly, L. monocytogenes biofilms developed at 10°C were less susceptible to the sanitizers than those formed at 32°C. In addition, LEO presented a more significant dispersing effect on the biofilm cells, and 1/2 MIC to 4 MIC of LEO could induce fewer VBNC state cells in biofilm and plankton compared with sodium hypochlorite. This study indicated that the LEO could be considered as an ideal antibiofilm agent for controlling L. monocytogenes. But we should pay attention to the resistance of the biofilms developed at low temperatures.

The Use of Lavender (Lavandula angustifolia) Essential Oil as an Additive to Drinking Water for Broiler Chickens and Its In Vitro Reaction with Enrofloxacin.

Simple SummaryEssential oils can stimulate the growth and functioning of the body, which translates into both chickens’ health and enhanced production parameters. Given the increasing restrictions imposed on poultry production in terms of food safety, it seems appropriate to look for the use of new, natural substances to be applied in poultry production. The article presents the results of the study of lavender essential oil in this context, with a particular focus on its antimicrobial and immunostimulatory properties. The purpose of the study was to determine the influence of lavender essential oil (added to drinking water at concentrations of 0.4 mL/L) on the production parameters and selected blood parameters in broiler chickens and to assess the lavender oil in vitro reaction combined with a commercial antibiotic, enrofloxacin, against Escherichia coli. The results of the experiment showed that the lavender essential oil exerts antimicrobial and antioxidant activity and it also showed a positive effect on the production results of broiler chickens.Biological activity of lavender essential oil is a property that can potentially find an application in poultry nutrition. Nowadays, the use of bioactive compounds is encouraged in many areas of industry and agriculture, since these substances have similar properties as withdrawn antibiotic growth promoters. Additionally, antibiotic resistance bacteria are one of the most important current threats to animal health. The purpose of the study was to determine the influence of lavender essential oil on the production parameters and blood parameters in broiler chickens and to assess the lavender oil’s in vitro reaction in a combination with enrofloxacin towards Escherichia coli. One-day-old non-sexed chicks (Ross 308) were divided into three experimental groups, each consisting of 100 individuals (five replicate of 20 boiler chicken each). The chickens in the control group received drinking water with no addition of lavender essential oil. In the experimental groups, lavender oil was added to the drinking water at a concentration of 0.4 mL/L, in the LEO1–42 from 1 to 42 days of age and the LEO22–42 group from the 22 to 42 days of age. The chickens’ body weight, feed consumption, water consumption, deaths and elimination due to health reasons were determined in the experiment. On day 42 of the chickens’ lives, blood samples were collected based on which selected parameters were identified. An in vitro experiment of lavender oil in combination with enrofloxacin was investigated with a checkerboard method. The results of the experiment showed the antimicrobial and antioxidant activity of lavender essential oil and its positive effect on the production results of broiler chickens. The study results proved that the addition of lavender oil positively impacted the chickens’ final body weight and feed conversion ratio (p < 0.01). No differences were observed between the groups for water consumption, death rate and the examined biochemical and immunological blood serum indices. Lavender essential oil was demonstrated to increase the blood serum’s total antioxidant status. A synergistic reaction in vitro was observed for lavender oil combined with enrofloxacin against resistant strains of Escherichia coli. Based on our study, a health-promoting effect of adding LEO to water for broiler chickens was found. Moreover, in vitro studies indicate a significant effect of lavender essential oil on the inhibition of the resistant strains of Escherichia coli growth and synergistic reaction with enrofloxacin.

The Mechanism of Lavender Essential Oil in the Treatment of Acute Colitis Based on "Quantity-Effect" Weight Coefficient Network Pharmacology.

This study aimed to introduce a new weight coefficient combined with network pharmacology to predict the potential active components, action targets, and signal pathways of lavender essential oil and to investigate the therapeutic effect of lavender essential oil on colitis through animal experiments. The component targets of lavender essential oil were mined from the Pubchem and SwissTargetPrediction databases, and the relative content of lavender essential oil was compared with OB (oral bioavailability) to establish a “quantity–effect” weight coefficient. Online databases such as GeneCards and String were used to construct a “lavender essential oil compound target disease target” network to extract the key targets of core compounds acting on diseases. The clusterProfiler package in R language programming of Rstudio software was used to analyze the enrichment of the related targets by Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes (KEGG), and the enriched pathways were reordered according to the “quantity–effect” weight coefficient of the targets they participated in. Following up on the findings, the pharmacodynamic test showed that, after injecting lavender essential oil into mice, the levels of inflammatory cytokines including EGFR, TNF-α, and IFN-γ in serum and colon tissue decreased, and lavender essential oil could mediate Th17 cell differentiation by reducing dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) colonic mucosal damage. The results indicated that lavender essential oil can alleviate DSS-induced colonic mucosal injury in ulcerative Colitis mice. Based on the network pharmacology of the “quantity–effect” weight coefficient, this study indicated that lavender essential oil can regulate the level of inflammatory factors, inhibit inflammatory reactions through a multicomponent and multitarget strategy, and ultimately alleviate the colonic mucosal injury of UC mice. Through the weight coefficient network pharmacology mining, it was concluded that the Th17 cell differentiation, PI3K-Akt signaling pathway, and Th1 and Th2 cell differentiation of lavender essential oil in the treatment of UC may be the key pathway for the treatment of the disease. Through the establishment of a weight coefficient combined with network pharmacology and the combination of dose and effect, it shows that network pharmacology may provide a better basis for the treatment of disease mechanism.
