“…The chromium level in the analyzed plants (under 1 mg/kg, except mint, plantain, and lavender) in other papers is either approximately the same for lavender [42, 57] and for mint [43, 46] or greater for coriander, chamomile, and dill [42, 43, 45, 58]. These papers state Cr recoveries, depending on the preparation method used, in the infusions of 3.6 to 10.9% (coriander, mint, and chamomile, 2.5 g plant in 50 ml water, [46]) or 59 to 80% (chamomile, 2 g dry plant in 100 ml boiling or hot water, 5 minutes, [58]).…”

The metallic elements concentrations of medicinal plants (coriander, dill, Echinacea, lavender, chamomile, mint, and plantain, used for phytopharmaceutical products), cultivated in unpolluted region, were analyzed by neutron activation analysis. The essential nutrients, macro-, micro-, and trace elements (K, Ca, Mg, Na, Fe, Mn, Rb, Sr, and Zn), potentially toxic elements (Al, As, Ba, Co, Sb, Cr, and V), and rare earth elements were monitored and were compared with those presented in the literature. An estimation of their contributions to intake and toxicity for a person was made, which revealed that (a) teas prepared from the examined plants represent useful contribution to the food provided intake of three essential macronutrients (K, Ca, and Mg); (b) the Cu, Mn, Rb, Sr, Zn, and rare earths levels are normal or low; (c) the quantities of As, Ba, Co, Sb, Cr, and V do not represent toxicological concerns; (d) the examination of the estimated Al and Fe quantities recovered in infusions in the conditions of usual daily tea consumption is below the Tolerable Daily Intake values. The strategy of cultivation of medicinal plants in unpolluted areas is efficient and beneficial. However, individual plants ability to concentrate preferentially certain elements suggests controlling the contamination level of raw materials.

“…There is also a lack of regulation regarding the classification and labelling of essential oils, which is highlighted by the difficult challenge of identifying adulterated finished products. Compounding the issue even further, there is some inherent natural variation within oils as a result of the environmental and geological conditions during plant growth and harvesting [ 4 , 5 , 6 , 7 , 8 , 9 ].…”

“…Another form of adulteration amongst essential oils is referred to as environmental adulteration, where oils from a lesser-quality yielding geographical location is labelled as being derived from a higher-quality/valued geographical location. For example, essential oils harvested from some European countries are typically sold at a premium compared to oils harvested from Asian nations, not only because of reduced labor costs in Asia but because of the increased oil quality due to environmental and geographical factors [ 9 ]. Of note, Hassiotis et al [ 11 ] concluded that within a geographical location, essential oil quality can also varying due to habitat and diurnal changes at the site of production.…”

Chemometric Analysis of Lavender Essential Oils Using Targeted and Untargeted GC-MS Acquired Data for the Rapid Identification and Characterization of Oil Quality

et al. 2017

Standard raw material test methods such as the ISO Standard 11024 are focused on the identification of lavender oil and not the actual class/quality of the oil. However, the quality of the oil has a significant effect on its price at market. As such, there is a need for raw material tests to identify not only the type of oil but its quality. This paper describes two approaches to rapidly identifying and classifying lavender oil. First, the ISO Standard 11024 test method was evaluated in order to determine its suitability to assess lavender oil quality but due to its targeted and simplistic approach, it has the potential to miss classify oil quality. Second, utilizing the data generated by the ISO Standard 11024 test methodology, an untargeted chemometric predicative model was developed in order to rapidly assess and characterize lavender oils (Lavandula angustifolia L.) for geographical/environmental adulteration that impact quality. Of the 170 compounds identified as per the ISO Standard 11024 test method utilizing GC-MS analyses, 15 unique compounds that greatly differentiate between the two classes of lavender were identified. Using these 15 compounds, a predicative multivariate chemometric model was developed that enabled lavender oil samples to be reliably differentiated based on quality. A misclassification analysis was performed and it was found that the predictions were sound (100% matching rate). Such an approach will enable producers, distributers, suppliers and manufactures to rapidly screen lavender essential oil. The authors concede that the validation and implementation of such an approach is more difficult than a conventional chromatographic assay. However, the rapid, reliable and less problematic screening is vastly superior and easily justifies any early implementation validation difficulties and costs.

“…Tea tree oil acts as a human poison if ingested and human poisoning cases were registered in 2003 by the American Association of Poison Control Centres [15]. A high concentration of TTO and lavender oil could result in skin irritations or burns [15,16]. Pyrethrins are neurotoxic to lice with reported low toxicity to mammalian cells.…”

Background: Chemical head lice treatments used by parents to treat head lice infestation in their children due to their rapid and reliable removal of head lice. However, those treatments can be absorbed through the skin. Children are more sensitive to absorbing chemicals than adults. We hypothesized that synthetic chemical-based head lice treatments cause cytotoxic and genotoxic damage to human skin cells in vitro. Objective: To determine the cytotoxic and genotoxic damage of synthetic chemical-based head lice treatments on HaCaT human skin cells in vitro.Methodology: Cytotoxicity measured by the methyl tetrazolium cytotoxicity (MTT) assay and the crystal violet assay. Also, the mechanism of cell killing was identified by the apoptosis detection, via Flow cytometry assay. The cytokinesis block micronucleus (CBMN) assay detected the frequency of binucleated cells (BN) with micronucleus (MNi), to indicate genetic damage induced by head lice treatments.Results: Tea Tree Oil (TTO), Pure Lavender oil and Pyrethrum did induce significant cytotoxicity. Also, they enhanced both early apoptosis and late apoptosis/necrosis. However, two head lice treatments, Permethrin (Lice Breaker) and Maldison (Malathion) (KP24) did not induce cytotoxicity. Early apoptosis and necrosis were observed in Permethrin treatment and late apoptosis and early necrosis were measured in Maldison (Malathion) (KP24). Moreover, Permethrin (Lice Breaker) and Maldison (Malathion) (KP24) induced micronuclei (MNi) at a frequency significantly higher (range=15-25 MNi/1000 binucleated cells, n=3) than the background frequency (media alone control; MNi range= 6 MNi /1000 binucleated cells, n=3). Conclusion:This study indicates that exposure to chemical based head lice treatments enhanced cell death by both early apoptosis and late apoptosis/necrosis also induced chromosomal damage in human skin cells.
