Summary
Rosemary is an evergreen Mediterranean shrub whose strong fragrance has linked kitchens, gardens, ceremonies, perfumes and household preparations for centuries. Ancient writers described its scented leaves and use in wreaths, while later European gardeners propagated it by cuttings, used sprigs at weddings and funerals, and distilled the flowering plant for aromatic preparations. Modern human studies have also examined rosemary in relation to memory and hair growth.
Salvia rosmarinus
About
Rosemary (Salvia rosmarinus) has narrow aromatic leaves that are dark green above and paler beneath, with small blue to pale lilac flowers. It is an evergreen woody shrub and commonly flowers from spring into early summer, with a second flowering possible in favourable conditions. Native to the Mediterranean region, it prefers sun, free-draining soil and warmth, and can suffer in severe winter cold.
Fresh or dried rosemary leaves are used in cooking, while flowering shoots and leaves have also been used historically for aromatic waters, oils and household preparations.
From Ancient Wreaths to European Gardens
Dioscorides (Greek physician and botanist) described a strongly scented plant that Romans called rosmarinus, with narrow leaves green on one side and pale on the other, and noted that its shoots were used for making crowns. Pliny also recorded rosemary-like aromatic material used in fumigation, showing an early use of the plant’s fragrance beyond food.
By the seventeenth century, John Parkinson (English gardener and herbal writer) described rosemary as so familiar that it could be found in “every woman’s garden.” He observed it growing against warm brick walls, noted that hard winters could kill plants, and described propagation from slips or cuttings to replace losses.
Rosemary at Weddings, Funerals and in Perfumery
Parkinson recorded rosemary being given among friends at weddings and funerals. Its evergreen leaves, strong scent and flexible shoots made it well suited to sprigs, wreaths and remembrance customs.
He also described an elaborate rosemary-flower preparation made by sealing flowers in glass, keeping them warm for fourteen days, and then allowing an oily material to collect in another vessel. Later rosemary oil was produced by distillation, and rosemary became central to aromatic waters and perfumes, including the famous historical preparation known as Hungary Water.
What Are the Benefits of Rosemary?
In a human study of older adults with an average age of about 75, a low culinary dose of powdered rosemary — about half a teaspoon — improved speed of memory, while much larger doses did not produce the same benefit. The study suggests that normal culinary amounts may affect cognitive performance, but more rosemary was not necessarily better.
Does Rosemary Help Hair Growth?
In a human trial involving 100 men with androgenetic hair loss, a rosemary lotion used twice daily for six months significantly increased hair count, with results comparable to 2% minoxidil in that study. This finding applies to the tested rosemary preparation and does not mean that every rosemary product will produce the same result.
Rosemary in Food and Adriatic Tradition
Historical European cookery used rosemary with meat, fish, goose, marinades, vinegars and even flavoured spirits. On the Croatian Adriatic, rosemary has also been recorded in infusions, perfume, massage preparations, essential oil and herbal spirits such as travarica.
Across these different uses, the same feature keeps returning: rosemary’s intense aroma. People carried it as a sprig, cooked with it, distilled it, steeped it and preserved its scent in oils and spirits, allowing one Mediterranean shrub to move through ceremony, cuisine, household practice and modern research.
