Field Notes RSS

Aromatherapy is an acute intervention: a compound applied for its direct physiological or sensory effect in the moment. Nervous system fragrance is designed for consistent use at specific types of moments, with conditioned response as the intended long-term mechanism. Both use aromatic compounds with documented physiological effects. What differs is the design logic — and the kind of tool each one becomes over time.

Aromatherapy and functional fragrance share a starting point: scent can influence state. But they diverge significantly in craft, intention, and wear experience. Learn how Aerchitect bridges evidence-informed ingredients with fine fragrance composition standards.
