Vanilla Absolute (aromatherapy)

Vanilla Absolute is a dark brown, clear and viscous liquid of very rich, sweet and true-to- nature odor. An odorflavor description of this product would not be correct without the remark that the flavor is strongly dependent upon the type of vanilla used in the extraction.
