Rosemary has a long history of culinary and aromatic uses, in addition to applications in traditional herbal and Ayurvedic medicine.
The rosemary bush (Rosmarinus officinalis) is native to South America and the Mediterranean region. It’s part of the Lamiaceae family of plants, along with mint, oregano, lemon balm, and basil.
Many people enjoy rosemary tea for its flavor, aroma, and health benefits.
Here are 6 potential health benefits and uses of rosemary tea, as well as possible drug interactions and a recipe to make it.
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.
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.
Due to its antioxidant capability, rosmarinic acid is often used as a natural preservative to increase the shelf life of perishable foods.
When left untreated, high blood sugar can damage your eyes, heart, kidneys, and nervous system. Therefore, it’s critical that people who have diabetes properly manage their blood sugar levels.
Studies have shown that compounds in rosemary tea may lower blood sugar, suggesting that rosemary could have potential applications for managing high blood sugar among people with diabetes.
Though studies on rosemary tea specifically are lacking, test-tube and animal studies on rosemary itself indicate that carnosic acid and rosmarinic acid have insulin-like effects on blood sugar.
Experiencing stress and anxiety from time to time is common.
Though studies on rosemary tea specifically are lacking, evidence shows that drinking and inhaling compounds in rosemary tea may help boost your mood and improve your memory.
One study found that taking 500 mg of oral rosemary twice daily for 1 month significantly lowered anxiety levels and improved memory and sleep quality among college students, compared with a placebo.
Another 2-month study in 66 industrial employees noted that those who drank 2 teaspoons (4 grams) of rosemary in 2/3 cup (150 ml) of water daily reported feeling significantly less burnt out at their jobs, compared with those who drank nothing.
Some test-tube and animal studies have found that compounds in rosemary tea may protect the health of your brain by preventing the death of brain cells.
Animal research suggests that rosemary may even support recovery from conditions that can lead to brain damage, such as a stroke.
Other studies suggest that rosemary may prevent the negative effects of brain aging, even suggesting a protective effect against neurodegenerative diseases like Alzheimer’s.
While studies on rosemary tea and eye health are lacking, evidence suggests that certain compounds in the tea may benefit your eyes.
Animal studies have found that adding rosemary extract to other oral treatments can slow the progression of age-related eye diseases (AREDs).
