Why might a client react negatively to essential oils during treatment?

A client may react negatively to essential oils during treatment primarily due to personal allergies or sensitivities. This reaction can occur because individual bodies may react differently to various substances, including essential oils. Each essential oil is composed of numerous compounds, and some individuals may be allergic or overly sensitive to particular components found in these oils.

For example, a client with a known allergy to lavender might experience a reaction when exposed to lavender essential oil, leading to symptoms such as skin irritation, respiratory issues, or other allergic responses. It is crucial for practitioners to conduct thorough assessments of their clients' health histories, allergies, and sensitivities before beginning any aromatherapy treatment. This ensures the selection of appropriate essential oils and minimizes the risk of adverse reactions.

The other options suggest a blanket negativity towards essential oils that doesn't accurately reflect their nature. Essential oils are not always harmful; many are safe and beneficial when used correctly. While some essential oils can have side effects, it is not accurate to say that all essential oils have side effects; many people use them without issues. Additionally, while essential oils can lose potency over time, this does not directly cause a negative reaction in clients but rather relates to effectiveness rather than safety. Therefore, understanding individual client sensitivities is essential in aromatherapy
