Asafoetida, or hing, is one of perfumery’s most mysterious natural ingredients — a resin once known for its pungent, sulfurous aroma, now valued for its power to add depth and realism to modern fragrances. From Dior’s Tendre Poison to L’Artisan Parfumeur’s Premier Figuier and Balmain’s Vent Vert, perfumers have learned to tame this wild note, transforming it into a secret signature that makes perfumes more textured, green, and unforgettable.
