Why might a practitioner choose to use essential oils in combination rather than individually?

Choosing to use essential oils in combination rather than individually allows practitioners to create a more holistic therapeutic effect. When different essential oils are blended, they can complement each other's properties and enhance the overall benefits for the client. Each oil brings its unique characteristics and benefits to the table, and when combined thoughtfully, they can address multiple aspects of a condition or promote a more comprehensive sense of well-being.

For example, one essential oil might be particularly effective for relaxation, while another could boost immune function. By blending them, the practitioner can provide a synergistic effect, enhancing both the physical and emotional responses in the client. This approach aligns closely with the principles of aromatherapy, which emphasize the importance of treating the individual as a whole rather than focusing solely on isolated symptoms.

In contrast, the other options you provided do not capture the primary therapeutic reason for blending essential oils. While saving time, simplifying procedures, or avoiding sensitivity may have their own merits, they do not encapsulate the primary goal of achieving a holistic and synergistic therapeutic effect, which is fundamental to effective aromatherapy practice.
