Which of the following is a benefit of using essential oils in aromatherapy?

  1. They are inexpensive

  2. They have no side effects

  3. They can promote relaxation

  4. They are easy to apply

The correct answer is: They can promote relaxation

Using essential oils in aromatherapy is well-known for its ability to promote relaxation, which is a significant benefit. Essential oils such as lavender, chamomile, and bergamot have properties that can help calm the mind and body, reduce anxiety, and improve sleep quality. This is supported by various studies and practices in holistic health that recognize the therapeutic effects of certain scents on mental and emotional well-being. While the other options may have their own merits in different contexts, they do not fully encapsulate the primary and scientifically supported benefit of essential oils as effectively as the ability to promote relaxation. The focus on mental health improvements and the promotion of a soothing atmosphere is what makes aromatherapy particularly valuable within wellness routines.
