Comparison Between Studies

Commonalities in Research

Many studies suggest that aromatherapy may be beneficial for improving various symptoms. Additionally, aromatherapy is considered a safer and less side-effect-prone treatment compared to conventional therapies. 2

Differences in Research

The effectiveness of aromatherapy varies depending on the type and amount of essential oil used, the method of application, and individual sensitivity. Therefore, not all studies yield the same results. 5

Points to Note Regarding Real-Life Application

Essential oils can irritate the skin and respiratory system if used in high concentrations. Therefore, always follow the instructions on the product label regarding dosage.

Limitations of Current Research

Research on aromatherapy is still insufficient. Further research is needed, especially regarding its effectiveness and safety for specific illnesses. Moreover, many studies are small-scale and their results cannot be generalized. 5

Future Directions for Necessary Research

Large-scale clinical trials are needed to better define the effectiveness and safety of aromatherapy. Additional research is also required to investigate its effects on specific illnesses and its efficacy when used in conjunction with other therapies. 5

Conclusion

Aromatherapy is a potentially safe treatment method that may help alleviate various symptoms. However, it is crucial to consult with a doctor or pharmacist before using it. Remember to follow the instructions and use it safely, considering its potential side effects.
