While aromatherapy can be beneficial, it is essential to use these potent oils correctly. Understanding dilution is key; undiluted essential oils can cause skin irritations or reactions. Additionally, certain essential oils may pose risks or side effects, particularly if they interfere with any existing medication or health condition. Pregnant or nursing individuals should consult with a healthcare provider before using essential oils. Furthermore, quality plays a crucial role in the efficacy and safety of aromatherapy, so ensure to source from reputable suppliers.
