**8. Conclusion**

In the light of the facts enlightened above, pain is a complex and subjective phenomenon that can be caused by a variety of factors. Pain relief is an essential aspect of healthcare and is necessary to alleviate suffering and improve quality of life. Further, pain relief can be achieved through drugs, therapies and alternative therapies [3]. Traditional medicine has strong cultural roots, and many plants are used to treat pain. On the other hand, this ancestral knowledge can be the source of inspiration for finding numerous active ingredients and accordingly enabling therapeutic innovation in the management of pain and inflammation. In conclusion, many aromatic plant species have essential oils with antinociceptive activity. As a general rule, animal studies are essential for research aimed at understanding complex questions in relation to disease progression or other biological mechanisms. Since the use of human subjects in research is ethically inconceivable, the need to use animal subjects in the initial research process is essential despite the complexity of assessing pain and its manifestations, as well as measuring pain effects of potential analgesic molecules. It remains for the researcher to choose the best tests to obtain answers and identify new effective compounds with analgesic and anti-inflammatory potential.
