**6. Addressing challenges in essential oil applications**

As the popularity of essential oils continues to soar, so do the challenges associated with their widespread applications. In this section, we explore the crucial aspects of potential safety concerns, sustainability and ethical sourcing issues, and the importance of regulatory considerations and standardization.

### **6.1 Potential safety concerns and precautions**

While essential oils offer numerous benefits, it is essential to recognize that their concentrated nature can pose safety risks if not used properly. Some essential oils may cause skin irritation or allergic reactions in certain individuals and others may interact with medications [47]. To address these concerns, it is crucial to practice responsible use and adhere to recommended dilution guidelines.

Ingestion of essential oils is a particularly contentious issue, as some oils can be toxic when taken internally [48]. Professional guidance from trained aromatherapists or healthcare practitioners is advised before internal use. Additionally, essential oils should be kept out of reach of children and pets to prevent accidental ingestion or exposure.
