USING CARRIER OILS
Essential oils are very concentrated and should always be diluted before use on the skin. Carrier oils are used for this purpose and are typically vegetable oils. Each carrier oil offers different properties and the choice depends on the therapeutic benefit being sought. Unlike essential oils, carrier oils do not evaporate or impart their aroma as strongly as essential oils. However, they usually have a shorter shelf life and can be mixed with a natural preservative such as vitamin E for longer storage. Carrier oils should be natural and preferably cold-pressed. This ensures that the therapeutic qualities remain in the oil and have not been damaged by heat or chemicals. Below is a list of the most commonly used carrier oils.
