Essential Nose Thyme ct. Geraniol
Thymus vulgaris ct. geraniol
Thymus vulgaris ct. geraniol is a chemotype of common thyme in which the acyclic monoterpene alcohol geraniol constitutes the dominant volatile fraction (approximately 26% of the essential oil), in contrast to the phenolic thymol or linalool that define other chemotypes.[1] Oils of this type, cultivated in southern France, exhibit potent antibacterial activity against Gram-positive organisms while retaining activity against Gram-negative strains, comparable to the other major chemotypes.[1] The geraniol-dominant fraction has also been shown to suppress LPS-induced IL-6 and TNFa secretion in BV-2 microglia via modulation of NF-κB and C/EBPβ signalling pathways.[2]
