What Is Rosemary?

Active Compounds in Rosemary

Rosemary contains several bioactive compounds, including:

• Rosmarinic acid – known for antioxidant and anti-inflammatory activity
• Carnosic acid – supports antioxidant defenses and cellular protection
• Essential oils (like 1,8-cineole) – contribute to aroma and potential respiratory support
