Centaurea Cyanus Flower Water is the aqueous extract of blue cornflower flowers (Centaurea Cyanus L., an annual plant belonging to the Asteraceae family and native to Europe) obtained by extraction with soluble ethanol and water.

The name defines the structure of the molecule:

• Centaurea Cyanus refers to the scientific name of the cornflower plant, also known as Centaurea cyanus. It is a flowering plant of the Asteraceae family and is native to Europe. Cornflower extract or flower water comes from the petals or other parts of the plant Centaurea cyanus.
• Flower Water. Flower water, also known as floral water or hydrool, is water obtained by steam distillation or maceration of plant materials, such as flowers or petals. It brings some of the aromatic and therapeutic properties of the plant from which it derives.

The synthesis process takes place in several stages:

• Collection of flowers. Centaurea Cyanus Flowers are collected only when they are in full bloom.
• Distillation. Collected flowers undergo a process known as steam distillation. In this process, the steam is passed through the flowers, causing them to release their essential oils. The steam and essential oils are then condensed back into a liquid.
• Separation. The resulting liquid contains both essential oil and floral water. These two components are separated, typically using a separator or allowing them to separate naturally due to their different densities. The floral water, or Centaurea Cyanus Flower Water, is then collected and is ready for marketing.

What it is used for and where

Medical

Centaurea Cyanus Flower Water is an aqueous extract obtained from the flower heads of the flower Centaurea cyanus, the common cornflower, which has a long history of herbal use and is used in biomedicine for the treatment of minor eye inflammations due to some interesting components such as uronic monocarboxylic acids (especially galacturonic acid) flavonoids, tannins and anthocyanins with anti-inflammatory activity . In traditional medical science, cornflower infusion was used as a mouthwash for gingivitis, ulcers, to improve digestion and against infections. Aqueous extract of cornflower was used for cleansing and care of the eyes, against conjunctivitis. The seeds as a laxative for children.
