Germacrone is a sesquiterpene ketone found in curcuma/zedoary and geranium oils. It smells warm-woody and earthy with a spicy, slightly camphoraceous herbal facet and a soft balsamic undertone. Rooty and dry rather than sweet, with a subtle green terpenic edge.AI · claude-opus-4-7

Very faint, sweet-woody, somewhat herbaceous odor of extraordinary tenacity.
It could find use as a modifying fixative in Ambre, Chypre and mossy fragrance types or bases.
Produced by isolation (freezing) from Bulgarian Zdravetz oil. This oil contains about 50 to 60% of the ketone.
