Why is dilution significant in aromatherapy?

Dilution is significant in aromatherapy primarily to ensure safe application and prevent irritation. Essential oils are highly concentrated substances extracted from plants and can cause skin irritation, allergic reactions, or sensitization when applied undiluted. By diluting essential oils with a carrier oil or appropriate base, the risk of adverse reactions is substantially reduced, making the oils safer for topical use. This practice not only enhances the user experience by minimizing potential discomfort or negative effects but also aligns with best safety practices in aromatherapy.

While aspects like enhancing fragrance, increasing shelf life, and potency also play roles in the use of essential oils, they do not address the direct concern of safe application. Ensuring that essential oils are used correctly and safely is the primary reason for dilution, making it the most significant consideration in aromatherapy practice.
