Shown to the right is a bottle with a rubber dropper top. It's okay to use a bottle with dropper top to store essential oils that are blended with carrier oils at very low dilution for a few months or less. However, do not store pure, undiluted essential oils in bottles with rubber dropper tops. The rubber will turn to mush and ruin the oil. It's okay if the bottle has a plastic orifice reducer (euro dropper) insert inside the bottle as the material can withstand essential oils.

You can use essential oils in any number of ways. For example, add them to body lotions or carrier oils, and then apply them topically. Try enhancing a facial toner, shampoo, or conditioner with essential oils. Or incorporate them into liquid soap, toothpaste, or mouthwash. You can also diffuse or spritz the oils throughout a room or pour them into a bath.
