Allergic contact dermatitis was also linked to Laurus nobilis oil used for massage as reported in a 36-year-old man presenting a generalized erythem-atous and edematous dermatitis being more severe at the back and dorsal parts of the legs. The latter revealed to have undergone a massage 2 weeks earlier, with a mixture of olive and L. nobilis oil applied to his back, thighs, and dorsal aspect of the limbs. Following exposure to the massage oils, skin dermatitis was developed three days later which progressively spread to the rest of the body. He also related to have applied once L. nobilis oil to his knee, under occlusion, to alleviate pain. A short course of oral steroids (40 mg/day) was started. The lesions reacted fastly to this treatment causing the erythema to fade over 2 weeks, leaving post-inflammatory pigmentation. Patch testing showed reactions to laurel oil and to the mixture of olive oil and laurel oil and Önder,

Nymphaeales consists of three botanical families: Cabombaceae, Hydatellaceae and Nymphaeaceae. The last of which has a cosmopolitan distribution and includes species such as Nymphaea amazonum (water lily), which has antimicrobial effects for the treatment of ulcers (Fenner et al. 2006). Phylogenetic studies showed that Chloranthales would be the sister order of the clade of Magnoliids, which brings together four orders: Piperales, Canellales, Magnoliales and Laurales. These orders contain the main botanical families with EOs, such as Piperaceae (in Piperales), Annonaceae and Myristicaceae (in Magnoliales) and Lauraceae (in Laurales). Avocado (Persea americana) is one of the most known Lauraceae fruits consumed worldwide, but it is not the only famous species in this family. Laurus nobilis (laurel) present several uses as a food ingredient, in alternative medicine, and also in ancient cultures, such as classical Greco-Roman for cultural purposes, its leaves were used to make wreaths given in honour to heroes and poets (Fig. 2.4).

Laurus nobilis L. is an evergreen shrub up to 8 meter in height and commonly named bay laurel. This tree belongs to the Lauraceae family and is native to the southern Mediterranean region and widely cultivated in Europe and the USA as an ornamental plant. In North African countries (Tunisia, Algeria, Morocco), bay laurel is a common species. It is grown commercially for its aromatic leaves in Turkey, Algeria, Morocco, Portugal, Spain, Italy, France and Mexico (28). The (fresh and dried) leaves are commonly used as a spicy, aromatic flavouring for soups, fish, meats, stews, puddings, vinegars, and beverages and also has food preserving properties from its antibacterial effects. Benzene compounds such as eugenol, methyl eugenol and elemicin are responsible for the spicy aroma of bay leaves (1). The leaves are also widely used in folk medicine to treat a variety of diseases.

In this context, SEM images showed the aggregation of particles. Aggregation defects may be due to the existence of water that stimulated Ostwald ripening during the freeze-drying process (Du et al.2016). SEM photographs of neem gum nanoformulation exhibited the presence of aggregates (Kamaraj et al.2018). In the EDX spectrum, Carbon (62.82%) and oxygen (22.33%) peaks might be originated from A. indica extract, Sulphur (8.23%) and sodium (6.37%) peaks might be derived from the SLS stabiliser, which was used for the stabilisation of A. indica nanobiopesticide. EDX spectrum confirmed the high purity of prepared nanobiopesticide with little contamination. Fakhari et al. (2019) recorded the EDX spectrum of zinc oxide nanoparticles formulated with an aqueous extract of Laurus nobilis L. leaves. FTIR spectrums of optimised nanobiopesticide and SLS stabiliser have a better resemblance. This fact may be due to some physical or chemical interactions among crude extract, stabiliser, and antisolvent during nanobiopesticide formulation (Nath and Roy 2017).

Laurus nobilis is an evergreen tree of Lauraceae family commonly used for culinary and medicinal purposes. It is thought to have origin in Mediterranean region and in Asia (1, 2). In Tunisia, this plant is a common species called “Rand.” It is particularly widespread in Tunisia at the edges of rivers, on mountains, and on wet cliffs. It also grows in the humid and subhumid bioclimatic areas, especially in the regions of Ain Draham, Tabarka, Kef, and Cap-Bon (3).
