These benefits are usually achieved through methods including inhalation and application of the diluted oil to the skin. For detailed profiles on over 70 oils, see the Oil Profiles area. Careful inhalation of the oils can also provide therapeutic benefit as the oil molecules enter the lungs and are absorbed into the bloodstream. Essential Oils are usually sold for individual use in very small bottles. See the Storing Your Oils page for information on how to store your oils and to view pictures of essential oil bottles.
Essential oils can very greatly in quality and price.
Various factors that can affect the quality and price of the oil include the rarity of the plant, country and conditions that the plant was grown, quality standards of the distiller, and how much oil is produced by the plant. Essential oils can often be purchased as blends of several essential oils. The advantage if it is a blend of pure essential oils is that you can save from having to buy every essential oil individually. The disadvantage is that you have no control over the blend by not mixing it yourself nor can you reliably mix the blend with other oils. The Vendor Pavilion within AromaWeb's Business Plaza lists sellers of essential oils and aromatherapy products.
