High in antioxidant, antimicrobial, and anti-inflammatory compounds
 
Antioxidants are compounds that help protect your body from oxidative damage and inflammation, which can lead to chronic diseases like cancer, heart disease, and type 2 diabetes (3Trusted Source).
They can be found in a variety of plant foods, such as fruits, vegetables, and herbs like rosemary. Rosemary tea also contains compounds that may have anti-inflammatory and antimicrobial properties.
 
The antioxidant and anti-inflammatory activity of rosemary is largely attributed to its polyphenolic compounds like rosmarinic acid and carnosic acid (4Trusted Source, 5Trusted Source).
Due to its antioxidant capability, rosmarinic acid is often used as a natural preservative to increase the shelf life of perishable foods (6Trusted Source, 7Trusted Source).
 
The compounds in rosemary tea may also have antimicrobial properties, which may help fight infections. Rosemary leaves are employed in traditional medicine for their antibacterial and wound healing effects (6Trusted Source, 8Trusted Source, 9Trusted Source).
 
Studies have also investigated the effects of rosmarinic and carnosic acid on cancer. They have found that the two acids may have antitumor properties and even slow the growth of leukemia, breast, and prostate cancer cells
