Rosmarinus Officinalis Rosemary Extract is a product of the rosemary plant, which is an aromatic shrub of evergreen origin and grows in the Mediterranean area and is currently being grown in several regions around the world with temperate climates, such as Southern Europe, North Africa, and some areas of Asia. The extract is derived mostly from the dry leaves that are gathered when the plant is at its optimum active compounds. The extract has high levels of phenolic diterpenes, flavonoids, and essential oils, which are the ones that give the extract its functional properties. The normal production process in industries includes dried and milled leaves, solvent extraction, supercritical CO₂ extraction, or water-ethanol extraction to maintain high yield and active constituents like carnosic acid, rosmarinic acid, and ursolic acid. They are standardized to fulfill regulatory and quality demands so that manufacturers are able to provide extracts with varying levels of consistency and purity to be used in food preservation, dietary supplements, pharmaceuticals, and personal care. Sustainable production of rosemary also adds to the supply of the extract since the plant is drought-tolerant, thrives well in unproductive soils, and has low agricultural production requirements relative to other medicinal herbs; thus, it is an environmentally friendly raw material to use in large-scale industrial production.

Rosmarinus officinalis, commonly referred to as rosemary, has a rich and ancient history that goes back thousands of years, and its application has been in culinary, medicinal, and cultural practices. Rosemary started in the Mediterranean basin, where it was very much treasured in ancient civilizations in Egypt, Greece, and Rome, where it was linked to memory, cleansing, and securing. The history of the Egyptians indicates that rosemary has been used in burial ceremonies in the past, as the Greeks and Romans applied it in ceremonies, medicine, and cooking. It was also grown in monastery gardens and was commonly used as a natural preservative, aromatic herb, and in traditional remedies in the Middle Ages in Europe. It was also associated with faithfulness and memory since it was frequently placed in weddings and burials. By the Renaissance, the spread of rosemary had reached the whole of Europe, where it was added to herbal pharmacopoeias as well as household recipes, especially as a preservative and cleansing agent. The familiarity of the functional property in the world trade and industry processes over time resulted in the extraction of bioactive compounds in the rise of food, nutraceutical, cosmetic, and pharmaceutical industries. This abundant history determines the timeless relevance of Rosmarinus Leaf Extract, which is one that links the traditional tradition with modern science and the business world.
