Common Names: Orris Root, Orris Butter, Beurre d’Iris, Orris Absolute

Description:
Orris is derived from the aged rhizomes (rootstock) of the iris plant—primarily Iris pallida and Iris florentina. The roots are aged for a minimum of three years to develop their fragrance, which is then extracted through several methods to yield various perfumery materials. Rich in α-irones, the aromatic compounds responsible for its violet-like, powdery aroma, orris is one of the most prized and expensive materials in natural perfumery.

Types of Orris Extracts

• Orris Butter (Beurre d’Iris):
  Obtained by steam distillation of aged roots. Despite the term "butter," it is not a true concrete, but a semi-solid, creamy mass.
  Aroma: Warm, sweet, powdery, violet-like; long-lasting and elegant.
  Regions: France, Italy, Morocco

• Orris Absolute:
  Extracted via solvent washing of orris butter, followed by careful vacuum distillation.
  Appearance: Pale yellow liquid.
  Aroma: Delicate, floral, faintly woody; used sparingly due to rarity and cost.

• Orris Resinoid ("Resin"):
  Produced by solvent extraction (e.g., with ethanol) from aged root.
  Texture: Honey-like, viscous.
  Note: Often more affordable than butter or absolute. Technically a concrete but called a "resin" due to its texture.

• Orris Powder:
  Ground aged root used in cosmetics, herbal sachets, and potpourri.
  Functions as a fixative and mild fragrance.

"This term is a compound of two Greek words meaning "plant" and "healing" and is used to describe all forms of treatments using plants. In France this term is used to describe what we would call Medical Herbalism but aromatherapy is often included under the same heading"...Patricia Davis in "Aromatherapy, an A to Z".

It can be argued that perfumes created using vibrant, natural plant materials and extracts with no synthetic or chemical additives could also be regarded as a branch of Phytotherapy.

Fatty substance obtained through enfleurage; the pomade is then used for solid perfume making, or it is further processed by soaking the pomade in high proof alcohol for several weeks to obtain a fragrant tincture which is filtered and used to make alcohol based perfume.
