What is Rosemary Leaf Extract?

Rosemary leaf extract is an aromatic evergreen shrub (Rosmarinus officinalis) and perennial plant with leaves similar to eastern hemlock pine needles. Originating in the Mediterranean, it has been used as an herb in cooking, making perfumes and essential oils, and is known for its potential health benefits. The leaves are often dried and used as a flavoring in various foods such as stuffing and meats. Rich in vitamins, iron, and calcium, the dried leaves are also used to make herbal teas. Rosmarinus officinalis (rosemary) leaf extract also contains rosmarinic acid, which has antioxidant, anti-inflammatory and antimicrobial activities.

Rosemarinic acid is a compound found in a variety of plants such as basil, lemon balm, and thyme and was first isolated and characterized by the Italian Chemists M.L. Scarpatti and G. Oriente from Rosemary (Rosmarinus officinalis). It can also be found in other plant species such as mint and nettle. Rosmarinic acid is a caffeic acid ester of 3, 4-dihydroxyphenylactic acid.
