Lavandula angustifolia belongs to family Lamiaceae and it is native to countries around the Mediterranean Sea (Spain, France, Italy, Turkey, Syria, Egypt, etc.). For centuries, extracts of genus Lavandula were used by the natives as antibacterial, tranquilizer, antifungal, antidepressive and were also effective for insect bites and burn wounds (Cavanagh and Wilkinson 2002). Moon et al. (2006) reported the significant potential of Lavandula angustifolia and Lavandula × intermedia oils extract on three protozoal parasites including Trichomonas vaginalis, Giardia duodenalis and Hexamita inflata. Oil extracted from these plants is used in three various concentrations of 1%, 0.5% and 0.1% against T. vaginalis and both show almost same results. L. angustifolia oil at 1% concentration caused 100% death of T. vaginalis after 20 min and at 0.5% concentration after 30 to 35 min, respectively. However, 0.1% gave less satisfactory results as compared to other concentrations and require 65 to 80 min of exposure to kill T. vaginalis. Microscopic examination of T. vaginalis shows the lysis of cells, but further studies are required to understand the exact mode of action of these oils and for identification and separation of the active molecule for its action on T. vaginalis (Moon et al. 2006).

Lavandula genus also belongs to Laminaceae with over 40 species, mainly existing as hybrids. This genus, originally from Europe, has been widely spreading and nowadays is commonly cultivated in North America and Australia (Figure 8.1) (Erland and Mahmoud, 2016). Among the species from this genus, it is worth emphasizing that Lavandula angustifolia and Lavandula latifolia are the most frequently used over the last decades, due to their therapeutic properties (Table 8.1) (Pistelli et al., 2017). These plants are often confused because different names are used. L. angustifolia is also known as Lavandula officinalis or English lavender, French lavender, and true lavender. Lavandula latifolia is also called as Lavandula spica, spike lavender or spike. The clinical properties of these plants depend on the specie, thereby L. angustifolia has sedative, relaxant, and hypotensor properties, while Lavandula latifolia can be used as stimulant and expectorant (Buckle, 2015). Another species with medicinal properties in this category is Lavandula stoechas. This species is very common in Mediterranean area, and often used for its expectorant and digestive effects, while also being applied topically to disinfect wounds.

Lavender, a member of the Lamiacease family, is widely used in a variety of herbal treatments and cosmetic products (Vakili et al. 2014; Souri et al. 2019). Lavender oil (Lav), extracted from the flower of Lavandula angustifolia L., has been reported to have anti-inflammatory, antioxidative, antinociceptive, antimicrobial, anti-depressive and anticancer properties in various investigations (Panahi et al. 2014; Silva et al. 2015; Qadeer et al. 2018; Souri et al. 2019; Boukhatem et al. 2020). For instance, lavender essential oil (LVO) combined with meropenem treatment-induced oxidative stress in Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-KP) cells by elevating the levels of lipid peroxidation and ROS, thereby repressing the growth of KPC-KP, ultimately reducing the threat to human health (Yang et al. 2020). Another study revealed that Lav alleviated renal ischemia/reperfusion injury in rats by repressing oxidative stress, inflammation and cell apoptosis (Aboutaleb et al. 2019). Based on these findings and the pathological characteristics of ALI, we speculated that Lav may also play a role in the treatment of ALI.

To date, the data on the effect of essential oils of different groups on the human cognitive abilities, in particular memory, have been accumulated. The similar work was carried out in model animals. The effect of two different essential oils of lavender obtained from Lavandula angustifolia ssp. angustifolia Mill. (Lamiaceae) и Lavandula hybrida Rev. (Lamiaceae) on the activity of nervous processes on the background of introduction of scopolamine alkaloid to rodents in the dose of 0.7 mg/kg was studied in male rats of Wistar line to induce the model of dementia. The chronic use (daily for 7 days) of the essential oils of lavender led to the numerous positive effects: manifestations of anxiety significantly decreased, antidepressive effects and improvement of the spatial memory were observed.4

For the 5HT system, St. John’s Wort (Kasper & Dienel 2002; Kasper et al. 2010; Kasper 2015) has a 5HT-modulatory effect, while additional action on other neurotransmitters, including NE, DA and Glu, also has been proposed (Kaehler et al. 1999; Barnes et al. 2001; Müller 2003; Vance et al. 2014). Whether this herb has a true anti-depressant action been the subject of debate for years (Hypericum Depression Trial Study Group 2002; Linde et al. 2005, 2008), and the possibility of a placebo effect has also been studied (Chen et al. 2015). The flowering plant Lavandula angustifolia is well known for its sedative action. It has recently been shown, using brain imaging techniques, to act through the 5HT1A receptor (Baldinger et al. 2014; Kasper et al. 2017).
