Rosemary tea has been treasured for centuries as both a culinary herb infusion and a traditional wellness remedy. Known for its fragrant aroma and slightly pine-like taste, rosemary tea is often associated with improved memory, digestion, circulation, and overall vitality. Modern research now supports many of the traditional claims surrounding this powerful herbal beverage. In this guide, you will learn everything about rosemary tea — from its proven health benefits to possible side effects, preparation methods, and safety precautions.
What is Rosemary Tea?
Rosemary tea is an herbal infusion made from the leaves of Rosmarinus officinalis, an aromatic evergreen herb belonging to the mint family (Lamiaceae). Native to the Mediterranean region, rosemary has long been used in cooking, traditional medicine, and natural remedies.
The tea is prepared by steeping fresh or dried rosemary leaves in hot water. Unlike traditional teas such as green or black tea, rosemary tea is caffeine-free, making it suitable for people who are sensitive to stimulants. Rosemary contains powerful bioactive compounds such as rosmarinic acid, carnosic acid, and various antioxidants that contribute to its health-supporting properties.
