What is rosemary essential oil?

Rosemary essential oil is obtained from the leaves and flowers of rosemary (Rosmarinus officinalis), a Mediterranean aromatic plant known for its stimulating and purifying properties. Extraction is typically done by steam distillation, a method that preserves the bioactive compounds responsible for its therapeutic properties.

The main chemical constituents of this oil include cineole, camphor, borneol, alpha-pinene, and limonene. The names may sound complicated, but their potential is broad: they have anti-inflammatory, antimicrobial, antioxidant, analgesic, and even central nervous system stimulant properties—which explains the diverse uses of ^rosemary essential oil.

Rosemary essential oil is used in aromatherapy, cosmetics and phytotherapy (the therapeutic practice that uses plants to prevent and treat diseases), with various scientifically proven benefits:

● Cognitive stimulation and concentration: Several studies indicate that inhaling rosemary's aroma helps improve memory, attention span, and mental clarity. This effect is primarily associated with cineole, one of the plant's main active compounds, which has a significant impact on cognitive performance ^1,2 ;

In addition, rosemary improves blood circulation in the scalp, strengthening hair follicles and stimulating healthy hair growth;
