Therapeutic Properties
Chemistry
Primary Constituents
Bornyl acetate (30-37%), alpha-pinene (12-17%), camphene (12-16%), beta-pinene (5-10%), delta-3-carene (6-12%), limonene (3-6%)
Emotional & Psychological
Classically cited in French aromatherapy as an adrenal tonic, it supports those who feel chronically depleted, overworked, or burned out. Emotionally it combines grounding stability with a subtle uplift that restores vitality without jittery stimulation. It is especially valued during recovery from prolonged stress, adrenal fatigue patterns, and the heavy mental fog of extended overwork, fostering both resilience and a sense of inner quiet strength.
Physical Therapeutic Uses
Widely used in French-school aromatherapy for adrenal exhaustion, with applications along the kidney area at low dilution. Respiratory uses include bronchitis, sinusitis, and chronic congestion. Its anti-inflammatory esters also address muscular fatigue, joint stiffness, and rheumatic discomfort. Frequently combined with black pepper, rosemary, and citrus oils in fatigue-recovery blends, it is also prized in spa and sauna applications.
