Blue Nile Botanicals Oil Collections consist of two types of oils, Essential oils and Cold Press Plant Oils.

Essential oils, also referred to as "essences", are botanical extracts of various plant materials, and do not only originate from flowers, but from herbs, trees and various other plant material.

Cold Pressed/Plant Oil is oil produced through a combination of grinding and low heat. Many types of fruits, seeds, and vegetables can be used to make it, but not all cooking oils go through this process.
