What is a potential side effect of using essential oils?

The selection highlighting skin irritation or allergic reactions as a potential side effect of using essential oils is valid and well-founded. Essential oils are highly concentrated plant extracts that can cause various skin responses when applied topically. These reactions can stem from the potency of the oils or an individual's unique sensitivity to specific components within the oils.

For example, essential oils like eucalyptus or tea tree may cause irritation or an allergic response in some individuals, particularly if they have pre-existing skin conditions or are using the oils in high concentrations. It is essential to always conduct a patch test before applying a new essential oil to a larger area of the skin to determine any possible sensitivities.

While nausea, weight gain, and dry eyes might be associated with certain conditions or substances, they are not commonly recognized as direct side effects of essential oils, particularly when used as directed in aromatherapy practices. Nausea might occur in some situations due to strong scents or improper use, but it is less specific to essential oils than skin reactions, which are a well-documented concern in aromatic therapies.
