**7. Conclusion**

*T. capitata* and *T. hyemalis* EOs are rich in phenolic monoterpenes (carvacrol and thymol), which are associated with antioxidant, antifungal, antibacterial, or antiparasitic properties. These EOs, due to their properties, can be used in pharmaceutical, food, livestock, agricultural, and pharmaceutical industries, being a potential source of economic resources. However, climate, edaphic factors, and genetics influence the chemical composition of these EOs. The high homogeneity of *T. capitata* EOs in climates with high temperatures and low humidity (carvacrol chemotype) can be an important economic resource of easy exploitation in arid and semiarid regions.
