**5. Conclusions**

*Lavandula stoechas* from the region of Saidona proved to be a good source of phytochemicals with a high in vitro antioxidant activity, especially in its aqueous form. In addition, numerous terpenoids were tentatively identified, producing a strong, penetrating and menthol-like odour. The mode of mechanistic action by the plant may involve its cultivation and exploitation under the prism of natural ''medicinal agents" that may favor the healthcare of humans. In parallel, the significance of its use as a supplement by the food industry or related industries in specific amounts may favor the preparation and distribution of health-promoting foods and beverages (HPFB) of a distinct flavour. Future research will be focused on the determination of the cytotoxicity of *Lavandula stoechas* dried proportions or aqueous extracts used in the present work (ca. 1%, *w v*<sup>−</sup>1), based on in vivo measurements, to approve or not its prospective use in different forms in foods or beverages.
