Rosemary (Salvia rosmarinus, formerly classified as Rosmarinus officinalis) is a fragrant, evergreen herb native to the Mediterranean region.  Revered for its aromatic, culinary, and medicinal properties, rosemary has been used for thousands of years in cultural rituals, traditional medicine, and cuisine.  The name "rosemary" comes from the Latin ros marinus, meaning "dew of the sea," reflecting its native coastal habitats.

Rosemary was sacred to many ancient cultures.  The Greeks associated rosemary with memory and intellect, and students often wore rosemary garlands during exams.  The Romans used it in religious ceremonies and as a symbol of loyalty and remembrance.  The Egyptians used rosemary in embalming rituals.  During the Middle Ages, rosemary was believed to ward off evil spirits and was burned in homes to purify the air.  In the Renaissance, rosemary became a symbol of love, often used in wedding ceremonies.

Rosemary was traded along Mediterranean trade routes as early as 2000 BCE, spreading its culinary, medicinal, and aromatic uses.  Phoenician traders likely helped disseminate rosemary to coastal communities.  Although not a major commodity like pepper or cinnamon, rosemary occasionally appeared in markets along the Silk Road as a luxury herb for medicinal and ritual purposes.  By the Middle Ages, rosemary had spread throughout Europe, cultivated in monastery gardens for medicinal and culinary purposes.    During outbreaks of the Black Death in the 14th century, rosemary was burned as incense or carried in pouches to ward off disease.  This protective symbolism made it a sought-after herb during times of crisis.

Rosemary was introduced to England by the Romans but gained prominence in the 14th and 15th centuries through the Norman conquest and Mediterranean trade connections.  By the 16th century, it was a common garden herb in Tudor England, used in cooking, medicine, and even as a strewing herb to freshen homes.  Unlike exotic spices such as cloves or nutmeg, rosemary was primarily cultivated locally in Europe. Wealthier European courts sought high-quality rosemary, especially from Italy and Spain, where it was prized for its aromatic intensity.    Rosemary was a key ingredient in "Queen of Hungary’s Water", one of the first European perfumes and early distillations.  In Christian traditions, rosemary became associated with the Virgin Mary, symbolizing fidelity and remembrance.  In countries like Australia and New Zealand, rosemary is worn on ANZAC Day (April 25) to honor fallen soldiers.

Fresh rosemary is widely available in grocery stores and gardens.  Dried rosemary is convenient for cooking, although it is less aromatic than fresh rosemary.  Rosemary oil is also used in aromatherapy and cosmetics.  Rosemary was historically believed to have many medicinal properties, which have some foundation in modern research.  These benefits include cognitive support, traditionally associated with memory and focus, and may improve cognitive function.  It is rich in antioxidants, and it contains rosmarinic acid, which is known to reduce inflammation.
