Blood

Blood is a rich, metallic scent derived from the iron-containing hemoglobin in human and animal blood. It has a deep, primal, and somewhat unsettling character, evoking images of violence, injury, and the visceral nature of life. Blood notes are rarely used directly in perfumery, but synthetic approximations can be found in certain niche and avant-garde fragrances.

Blood notes in fragrances can evoke a sense of danger, intensity, and raw primal energy. They are not typically associated with feelings of comfort or relaxation, but rather with a sense of excitement, mystery, and the darker aspects of the human experience. Fragrances featuring blood notes may be best suited for evening wear or special occasions where a bold, unconventional scent is desired.

Blood notes are rarely used directly in perfumery, as their raw, metallic character can be challenging to work with. However, synthetic approximations of the blood scent are sometimes found in niche and avant-garde fragrances, often blended with other dark, animalic notes to create a sense of intensity and mystery. These notes are typically used as base or heart notes to provide depth and complexity to the overall fragrance composition.
