Blue Tansy Oil pours out a deep ink-blue and smells nothing like the sharp common tansy. The scent is sweet and fruity, like ripe apple and warm honey, softened by a gentle herby-floral haze. A faint camphor coolness keeps it lively. Use Blue Tansy to bring a natural, chamomile-like sweetness to florals and to soften the green bite of aromatic and fougère accords. It rounds sharp herbs and lends a sun-warmed, fruity glow underneath top notes. A little goes a long way, since its colour and odour both take over fast. Think of it as a sweetener for herbal and apple-fruity effects rather than a loud feature. Trace amounts lift a chamomile or clary sage heart; a touch more pushes a blend toward jammy, wine-like richness. Its blue tint also tells you instantly how much you have added.
