Reduces stress, strengthens memory: The benefits of the miracle plant have been proven
Rich in vitamins, iron, calcium, magnesium, and potassium, rosemary also contains phytochemicals, plant compounds with antioxidant and anti-inflammatory properties. These substances may protect against chronic conditions like heart disease, diabetes, and some types of cancer by reducing the damage caused by free radicals in the body.
Rosemary, which has been used in traditional medicine for many years to prevent infections and heal wounds, also has antimicrobial effects.
A study conducted at Northumbria University found that elderly individuals who inhaled rosemary performed better on recall tests and felt more alert than those in an unscented environment. These positive effects were seen not only in older adults but also in younger adults.
A 2018 study found that university students who took 500 mg of rosemary supplements twice daily for a month had better results on memory tests, less anxiety and depression, and improved sleep quality.
Another study revealed that employees who drank rosemary-flavored water at work experienced less burnout.
According to experts, rosemary helps carry more oxygen and nutrients by increasing blood flow to the brain.
Its polyphenols may also help combat depression by supporting gut health and reducing inflammation. Rosemary also contains compounds like 1,8-cineole, which prevents the breakdown of acetylcholine, a chemical associated with learning and memory. Maintaining acetylcholine levels helps maintain mental acuity as we age.
Recent research has revealed that carnosic acid, a powerful antioxidant found in rosemary, may have protective effects against Alzheimer's disease. In 2025, scientists developed a more stable form of this compound, dubbed diAcCA, and tested it in a laboratory setting. The results were promising. This compound strengthened connections between brain cells, improved memory, and reduced levels of beta-amyloid and tau proteins, which are associated with Alzheimer's.
Moreover, diAcCA was only active in inflamed brain areas, minimizing potential side effects. Studies in mice showed no toxic effects and positive cognitive outcomes.
Approximately 7.2 million people over the age of 65 in the United States currently suffer from Alzheimer's disease. Unless new treatments are developed, this number is expected to rise to 13.8 million by 2060. At this point, the effects of rosemary on brain health are considered quite valuable.
