Essential oils are not only used for medicinal purposes, as many people believe. They are also used for aromatherapy, beauty care, and even spiritual devotion. Below is a list of the most expensive young living essential oils that can be purchased. 1. Frankincense The most expensive essential oil in Young Living is the Frankincense oil. Some companies sell it at a cost of up to $40 per 0.5oz bottle. The oil is obtained by boiling certain trees and then drying them into powder. It has anti-bacterial and astringent properties that are responsible for its use in ancient times as anointing oil and incense. 2. Rose The second most expensive oil comes from Rosa damascena – the damask rose. It is slightly sweet and has a nice rose scent. You can buy it for $26 for a 0.5oz bottle, which is much cheaper than Frankincense oil, but it still is an expensive product. The main reason for its high cost is that it is obtained from the petals of rose flowers by distillation process, steam or water extraction and then mixed with other essential oils to reduce its cost. 3. Ylang Ylang The Ylang Ylang essential oil is an essential part of the Young Living Premium Starter Kit. It has an exotic scent that makes it worth its price of $23 for a 0.5oz bottle. It is obtained by steam distillation process and then mixed with other oils to reduce its cost. When buying this product, you should always look for 100% pure ylang ylan oil with no additives or fillers.
