Lavender, particularly as the standardized oral preparation Silexan, exhibits anxiolytic (anxiety-reducing) and sedative properties by modulating GABAergic neurotransmission, similar to some pharmaceuticals but without the dependence risk. Its primary relevance to healthspan is through improving sleep quality and reducing chronic stress, both of which are critical for cellular repair, hormonal regulation, and mitigating age-related cognitive decline.
