Dilution Guidelines for Essential Oil Safety | aromatics.com (1)

Diluting essential oils refers to the process of mixing them with a carrier oil or other substances to reduce their concentration before use. Essential oils are highly concentrated plant extracts that contain volatile compounds with potent properties. While they offer numerous benefits, such as aromatherapy and natural remedies, they should be handled with care due to their strong effects. Dilution is essential for several reasons.

First, it helps ensure safety and minimizes the risk of adverse reactions. Undiluted essential oils can cause skin irritation, allergic reactions, or even burns. Dilution provides a gentler and safer application method.

Second, diluting essential oils allows for proper dispersion and absorption on the skin. Carrier oils act as a medium, aiding in the even distribution of essential oils and preventing evaporation. This enhances the effectiveness of the essential oil and maximizes its benefits.

Lastly, dilution indirectly extends the use potential of your oils, as using them sparingly allows for a more sustainable approach. Diluting essential oils promotes safety, enhances efficacy, and supports sustainable usage, making it a crucial practice for anyone incorporating these powerful extracts into their daily routines.
