A personal favorite! Black spruce essential oil is a wonderfully warm and energizing oil that is effective to diffuse alone, or blends well with many other oils- like cedar, frankincense, lavender, and patchouli. Black spruce can be useful for soothing respiratory problems such as coughs, colds and flu. Used in steam inhalations, diffuser blends or added to a hot bath it will help to open the airways and ease congestion. 5 ml. bottle.
