**6.3 Regulatory considerations and standardization**

The lack of consistent regulations and standardization in the essential oil industry can be a significant challenge. Different countries and regions may have varying guidelines regarding the production, labeling, and marketing of essential oils, leading to confusion among consumers and potential quality issues.

To address this concern, efforts are being made to establish industry standards and certifications. Organizations such as the International Organization for Standardization (ISO) and the European Medicines Agency (EMA) are working to create guidelines for essential oil quality, purity, and safety [47]. Seeking essential oils from reputable and transparent suppliers who adhere to these standards can help ensure product integrity and consumer confidence.

As the use of essential oils continues to evolve, it is imperative to address these challenges to ensure the safety, sustainability, and efficacy of their applications. Responsible use, ethical sourcing, and adherence to quality standards are crucial steps toward harnessing the full potential of essential oils while preserving the well-being of both individuals and the environment.
