Spruce, Black
Picea mariana
About
In French medical aromatherapy, Black Spruce essential oil (Picea mariana) is a core adrenal tonic and respiratory remedy, prized for its cortisol-like, anti-fatigue, and anti-inflammatory effects. It is classified as a corticoid-mimetic essential oil, used clinically to support adrenal exhaustion, chronic fatigue, or immune weakness.
In France, oils like Black Spruce are used in integrative medicine units, particularly in Hospitals & Clinics. Some examples are:
-
Clinique Saint-Raphaël (Paris)
-
Clinique du Parc Lyon
They are prescribed by MDs trained in aromathérapie scientifique for fatigue syndromes, respiratory illness, and adrenal support. -
HĂ´pital de Grasse (notably in respiratory and palliative care)
