Rosemary is a Mediterranean evergreen shrub cultivated for its aromatic and flavorful leaves all over the world. Because it can grow to be quite large and produce many white, light blue, or pale purple flowers, gardeners use it as a topiary or large ornamental bush. In addition to cooking, rosemary is used in cosmetics and aromatherapy treatments, as well as sachets to keep clothing smelling fresh and sweet. In some specialty stores, the herb is available fresh, as well as whole dried and powdered forms.
Rosmarinus officianalis is the Latin name for this plant, and the compound word rosmarinus means “sea dew.” This is likely due to the plant’s preference for a rugged environment; it thrives when left to its own devices, and can be found on cliffs and rocks along seashores. Rosemary is a drought-resistant plant that requires little maintenance, unless it is over-watered, in which case the roots rot and the plant droops and dies. It tolerates pruning well and can be pruned into a bush or low hedge.
The aromatic leaves are used in sauces, to rub meats, to grill with, and in a variety of other ways in the kitchen. They contain a pungent oil that gives food a distinct flavor, and the herb is commonly used to season Mediterranean cuisine from France, Greece, and Italy. Rosemary has been used in cooking for centuries, and it has been documented as a culinary ingredient since before the common era.
Since ancient times, both men and women have used this plant in cosmetics. Rosemary oil is used to scent women’s moisturizers and toners, as well as to make astringent toners for men to use after shaving or to improve their skin. It has mild antibacterial properties, making it an excellent addition to a shaving toner, and the herb’s scent is said to help with relaxation.
People exchanged rosemary as a symbol of loyalty and remembrance in medieval times, and it was frequently used in memorial wreaths for the same reason. Although it has not been shown to have any properties that could influence brain health, the herb is still associated with memory in Western culture. Pregnant women should avoid consuming large amounts of rosemary products because the herb can cause uterine contractions. Epileptics should avoid concentrated rosemary as well, as studies have shown that it contains a compound that may aggravate seizures.
