potential applications exist for these products in the beverage and food industry as natural antimicrobials [3]. Chapter 4 addresses \"Essential Oil of _Origanum vulgare_ var. _aureum_ L. from Western Romania: Chemical analysis, in vitro and in silico screening of its antioxidant activity\" [4]. This noteworthy chapter was reserved for an _Origanum_ genus member that has remained insufficiently explored, _Origanum vulgare_ var. _aureum_ L. The authors proceeded by assessing its EO chemical composition and antioxidant effects. The results of this investigation reveal that gamma-terpinene (22.96%) and para-cymene (14.72%) are the main compounds of the _Origanum vulgare_ var. _aureum_ essential oil (OEO) and that they demonstrate strong scavenging effects on the DPPH and ABTS assays and higher relative antioxidant activity in the beta-carotene/linoleic acid bleaching assay. Furthermore, in silico analysis results reveal that their main compounds may be responsible for the oil's antioxidant properties by inhibiting the ROS-producing enzymes known as lipoxygenase (LOX), and xanthin oxidase (XO). Chapter 5 (\"Chemical profile of _Ruta graveolens_, evaluation of the antioxidant and antibacterial potential of its essential oil, and molecular docking simulations\") evaluate the antimicrobial and antioxidant effects of the _Ruta graveolens_ L. essential oil (RGEO) [5]. The results contained in this chapter demonstrate that RGEO possesses broad-spectrum antifungal and antibacterial effects and moderate antioxidant properties. Moreover, molecular docking analysis shows that the RGEO can exert its antimicrobial activity by inhibiting the D-Alanine-d-alanine ligase and generating an in vitro antioxidant effect via cumulative XO and LOX inhibition. Therefore, the RGEO could comprise a new natural preservatives and antioxidants source with diverse food and pharmaceutical industry applications. Chapter 6 discusses the paper \"Phytochemical profile, antioxidant and wound healing potential of three artemisinin species: in vitro and in ovo evaluation\" [6]. This chapter proposes using ethanolic extracts of three _Artemisia_ species, _Artemisia absinthium_ L., _Artemisia dracunculus_ L., and _Artemisia annuua_ L., as new efficient alternatives in injury therapy. The results demonstrates that all three _Artemisia_ species can be promising low-cost, polyphenol, antioxidant, and safe choices in injury treatment. Chapter 7 is entitled \"Studies Regarding the Antibacterial Effect of Plant Extracts Obtained from Epibloium parifolium Schep\" [7]. This chapter evaluates the phytochemical contents of _E. parviform_ Schep. extracts (aqueous, hydroalcoholic, and ultrasonicated hydroalcoholic) and their potential antibacterial activity. The chapter records that hydroalcoholic extract have the highest content of polyphenols and flavonoids and possesses strong antibacterial properties. Additionally, the study concludes that the amount of polyphenols and flavonoids in the analyzed extracts directly influences the recorded antibacterial activity (_White Staphylococcus_, _Streptococcus mitis_, _Streptococcus sanguis_, and _Enterococcus faecalis_). Chapter 8 concerns the paper \"Evaluation of genetic damage and antigotoxic effect of ascorbic acid in erythrocytes of _Oreochromis niloticus_ and _Ambystoma mexicanum_ using migration groups as a Parameter\", which is marginally related to the topic of the Special Issue [8]. In this chapter, Prof. [PERSON] and his research team investigate the genetic damage in erythrocytes of _Oreochromis niloticus_ and _Ambystoma mexicanum_ exposed to ethyl methanesulfonate and ultraviolet C radiation. The results reveal that migration groups of cell comets allow the detection of basal and induce genetic damage or damage reduction with roughly the same tail length and tail moment parameters efficiency. These findings suggest the usage of migration groups as a complementary parameter to evaluate DNA integrity in species exposed to mutagens.
