Organic black spruce essential oil is steam distilled from the needles and twigs of Picea mariana. Also known as black pine, these evergreen trees grow across Canada and parts of the United States. This middle note conjures fresh coniferous forests and is found in many winter and holiday-themed blends, but can be enjoyed year round.
Spruce oil has a naturally high ester count. Natural esters are known to help you relax and balance the physical body and mental state. Spruce can help reduce symptoms of anxiety and depression and can increase serotonin and dopamine, both of which can positively influence your mood, reduce stress and help you sleep better. Spruce essential oil has antiseptic properties, making it useful for cleansing the skin, killing bacteria and fungi and healing skin wounds. 
Spruce essential oil is rich in monoterpenes which are antioxidants, and antioxidants can weaken certain viruses and support the immune system.
