Essential oils are extracts from specific plant parts such as petal, bark, peel, stem etc…. There is only a very small amount of oil in the plant part from which the oil is taken. Some oils such as Lavender produce a high yield of oil whereas Rose requires 30 to 40 rose heads to produce 1 drop of pure essential oil. Hence the cost of pure Rose makes it an investment and a worthwhile one at that.
Other factors which contribute to the final delivery and price of a pure essential oils include cultivation, farming methods, distillation and finally storage.
