A fragrance says more than 1,000 words - because smells form an important basis of communication. Smelling was and is immensely important for our lives. The human sense of smell has a particularly fast and direct connection to the brain. In particular to the limbic system, which primarily controls unconscious actions and serves to process feelings. This olfactory memory allows us to remember exactly what it smelled like in grandma's kitchen at Christmas - or on our first holiday in the alpine region - even decades later. If pleasant feelings are associated with a certain smell, we can trigger a feeling of well-being again by using this scent in a targeted way.
