Abstract Background Dysmenorrhea is an important disease that affects physical, social and psychological functioning such as social, emotional and health performance. The lavender essential oils are being used in both combined and mere forms. The purpose of this meta-analysis is to investigate the effects of lavender alone and in combination with other aromatic plants on the attenuation of dysmenorrhea. Materials and Methods The previously published articles were searched on only English databases of Medline, Cochrane library and scouts. Headings (MeSH) using the main keywords of (Lavandula OR lavender) AND (Dysmenorrhea) since inception until March 15 2019. We also searched all Iranian Databases with the same English keywords. Results Meta-analysis of lavender alone ‘showed that dysmenorrhea intensity was lower in patient treated with lavender in comparison to control: standardized mean difference [SMD] = -1.17, 95% confidence interval: -1.72 to-0.629. Heterogeneity was 85% and significant (p<0.001). Our meta-analysis showed dysmenorrhea intensity was lower in patients treated with compound containing lavender in comparison to control: SMD =-1.04; (p<0.001). Conclusion Given the patient's interest in complementary medicine and the low cost of this therapeutic approach, this technique can be used as a useful way to improve dysmenorrhea. The findings of these studies should be interpreted with caution because of the high heterogeneity between studies and the small number of studies and small sample size.

The oil is traditionally believed to have sedative, carminative, anti-depressive and anti- inflammatory properties, in addition to its recognised antimicrobial effects. Many of the activities attributed to lavender oil have not, however, been substantiated in the scientific literature. This is further complicated by the fact that the majority of research into lavender essential oils has been based on oil derived from English lavender (Lavandula angustifolia), with little or no differentiation being made between this and other lavender essential oils. The therapeutic potential of essential oils produced from other varieties, such as L. x intermedia (lavandin), L. stoechas (French lavender) and L. x allardii, have

Academic Editor: Muraleedharan G. Nair Received: 1 November 2014 / Accepted: 10 February 2015 / Published: 3 March 2015 Abstract: This review is a comprehensive introduction to pertinent aspects of the extraction methodology, chemistry, analysis and pharmacology of essential oils, whilst providing a background of general organic chemistry concepts to readers from non-chemistry oriented backgrounds. Furthermore, it describes the historical aspects of essential oil research whilst exploring contentious issues of terminology. This follows with an examination of essential oil producing plants in the Australian context with particular attention to Aboriginal custom use, historical successes and contemporary commercial prospects. Due to the harsh dry environment of the Australian landmass, particularly to the cyclical climatic variation attendant upon repeated glaciation/post-glaciation cycles, the arid regions have evolved a rich assortment of unique endemic essential oil yielding plants. Though some of these aromatic plants (particularly myrtaceous species) have given birth to commercially valuable industries, much remains to be discovered. Given the market potential, it is likely that recent discoveries in our laboratory and elsewhere will lead to new product development.

Received: 16 October 2020; Accepted: 20 November 2020; Published: 26 November 2020 Abstract: Lavender and its products have excellent flavor properties. However, most studies focus on the aroma profiles of lavender essential oil (LEO). The volatiles in lavender extracts (LEs), either in volatile compositions or their odor characteristics, have rarely been reported. In this study, the odor characteristics of LEs and LEO were comprehensively investigated by gas chromatography-mass spectrometry (GC-MS), coupled with sensory evaluation and principal chemical analysis (PCA). In addition, the extraction conditions of lavender extracts from inflorescences of Lavandula angustifolia Mill. were optimized. Under the optimal conditions of extraction, twice with 95% edible ethanol as the solvent, the LEs tended to contain the higher intensity of characteristic floral, herbal and clove-like odors as well as higher scores of overall assessment and higher amounts of linalool, linalool oxides I and II, linalyl acetate, lavandulyl acetate and total volatiles than LEO. PCA analysis showed that there were significant differences on the odor characteristics between LEO and LEs. The LEO, which was produced by steam distillation with a yield of 2.21%, had the lower intensity of floral, clove-like, medicine-like, pine-like and hay notes, a lower score of overall assessment and lower levels of linalool oxides I and II, linalyl acetate, lavandulyl acetate and total volatiles compared with LEs, whereas the relative contents of linalool and camphor in LEO were significantly higher than that in LEs.

  • The Therapeutic Benefits of Essential Oils
    7 The Therapeutic Benefits of Essential Oils Abdelouaheb Djilani1 and Amadou Dicko2 1LSBO, BADJI MOKHTAR-Annaba University, 2LCME, Metz University, 1Algeria 2France 1. Introduction Since ancient times, essential oils are recognized for their medicinal value and they are very interesting and powerful natural plant products. They continue to be of paramount importance until the present day. Essential oils have been used as perfumes, flavors for foods and beverages, or to heal both body and mind for thousands of years (Baris et al., 2006; Margaris et al., 1982; Tisserand, 1997; Wei & Shibamoto 2010). Record findings in Mesopotamia, China, India, Persia and ancient Egypt show their uses for many treatments in various forms. For example, in the ancient Egypt, the population extracted oils by infusion. Later; Greeks and Romans used distillation and thus gave aromatic plants an additional value. With the advent of Islamic civilization, extraction techniques have been further refined. In the era of the Renaissance, Europeans have taken over the task and with the development of science the composition and the nature of essential oils have been well established and studied (Burt, 2004; Peeyush et al., 2011; Steven, 2010; Suaib et al., 2007). Nowadays, peppermint, lavender, geranium, eucalyptus, rose, bergamot, sandalwood and chamomile essential oils are the most frequently traded ones. 2. Definition and localization of essential oils Essential oils (also called volatile or ethereal oils, because they evaporate when exposed to heat in contrast to fixed oils) are odorous and volatile compounds found only in 10% of the plant kingdom and are stored in plants in special brittle secretory structures, such as glands, secretory hairs, secretory ducts, secretory cavities or resin ducts (Ahmadi et al., 2002; Bezić et al., 2009; Ciccarelli et al., 2008; Gershenzon et al., 1994; Liolios et al., 2010; Morone- Fortunato et al., 2010; Sangwan et al., 2001; Wagner et al., 1996).

DOI: 10.1002/ptr.1103 REVIEW ARTICLE Biological Activities of Lavender Essential Oil H. M. A. Cavanagh and J. M. Wilkinson* School of Biomedical Sciences, Charles Sturt University, Wagga Wagga, NSW 2678, Australia Essential oils distilled from members of the genus Lavandula have been used both cosmetically and thera- peutically for centuries with the most commonly used species being L. angustifolia, L. latifolia, L. stoechas and L. x intermedia. Although there is considerable anecdotal information about the biological activity of these oils much of this has not been substantiated by scientific or clinical evidence. Among the claims made for lavender oil are that is it antibacterial, antifungal, carminative (smooth muscle relaxing), seda- tive, antidepressive and effective for burns and insect bites. In this review we detail the current state of knowledge about the effect of lavender oils on psychological and physiological parameters and its use as an antimicrobial agent. Although the data are still inconclusive and often controversial, there does seem to be both scientific and clinical data that support the traditional uses of lavender. However, methodo- logical and oil identification problems have severely hampered the evaluation of the therapeutic signifi- cance of much of the research on Lavandula spp. These issues need to be resolved before we have a true picture of the biological activities of lavender essential oil.

In this paper we review current research investigating the biological activities of lavender oil and highlight areas that require further investigation.
