Rosemary, also known as Rosmarinus officinalis, is a beautiful evergreen shrub with 1-inch long, needle-like leaves with clusters of white/pale blue flowers that blossom during winter and spring native to the Mediterranean (1). Rosemary has been used for its many medicinal purposes in the Mediterranean region for many years and has since been cultivated around the world (2).
Benefits of Rosemary
Rich In Antioxidants
Several studies have been done on rosemary’s ability to act as an antioxidant. Antioxidants can help fight damage from harmful free radicals. The buildup of free radicals has been linked to chronic diseases, such as cancer and heart disease (3). Due to the antioxidant capabilities of rosemary, early studies have found that rosemarinic acid is a great alternative to toxin-filled preservatives and can increase the shelf life of perishable foods thanks to its natural preservatives (4).
An antimicrobial property is when a substance, or in this case, an herb, can kill or suppress the spread of microorganisms such as bacteria, viruses, protozoans, and fungi (5). One study compared the antimicrobial activity of rosemary and sage essential oils. Rosemary was effective against Escherichia coli, Salmonella typhi, S. enteritidis, and Shigella sonei (6).
Rosemary is well-known for its anti-inflammatory properties, thanks to its antioxidant compounds, which can also reduce inflammation, especially from free radical damage. Chronic inflammation has been linked with many diseases, such as type 2 diabetes, asthma, and certain cancers (7). Several studies, including in vitro and in vivo, found that rosemary has a great source of anti-inflammatory agents and historically documented pharmacological effects (8).
May Lower Blood Sugar Levels
Several studies have found that rosemary has compounds called carbonic acid and tamarind acid, which have insulin-like effects on blood sugar (9). In several studies, they’ve found that these two compounds are linked to an increased rate of absorption of glucose into muscle cells, which in turn lowers blood sugar levels (10,11).
May Improve Mood, Memory & Brain Health
Many studies have been conducted around the possibility that rosemary may improve mood, memory, and overall brain health. One study found that taking rosemary orally two times a day for one month significantly lowered anxiety levels while improving memory and sleep quality amongst college students (12). Another study conducted on 66 industrial employees found that drinking two teaspoons of rosemary in 2/3 cup of water felt significantly less burnt out at their jobs (13). An animal study found that rosemary may even support recovery from conditions such as a stroke (14) and may even protect against neurodegenerative diseases such as Alzheimer’s (15).

Contraindications & Interactions
Rosemary has gained a reputation as being unsafe to take in pregnancy but in fact, there is no evidence that it will cause harm to the baby or mother
It is recommended not to take strong medicinal teas or extracts of Rosemary at the same time as taking iron supplements as studies have shown that it does significantly decrease the absorption of iron (only if taken simultaneously).
