**5. Conclusion**

In conclusion, there are multiple methods for extracting essential oils, and the process chosen can greatly affect the amount and quality of the oil produced. To maximize yields and maintain the natural structure of the oils, extraction processes have been developed. This chapter explores different extraction techniques, both conventional and intensified, highlighting their advantages and disadvantages. It is improved that new techniques have been proven to produce higher quality extracts in a shorter time compared to traditional techniques. However, regulatory standards do not list these extracts derived from innovative techniques as essential oils due to the narrow definition of essential oils based solely on conventional extraction methods. Furthermore, new environmentally friendly methods have been introduced to improve traditional essential oil production. Therefore, it is becoming increasingly crucial to modify or re-establish industry standards to encompass a broader range of extraction techniques.
