According to USDA, fresh rosemary has a very high reserve of vitamins such as vitamin A, vitamin C, vitamin B6, thiamin, folate, as well as minerals like magnesium, calcium, and iron. It has abundant antioxidants in its phenolic compounds such as diterpene, carnosol, and rosmarinic acid, as well as in its essential oils such as cineol, camphene, borneol, bornyl acetate, α-terpineol, and α-pinene.
Health Benefits of Rosemary
The top health benefits of rosemary include:
The oil of rosemary promotes hair growth, prevents baldness, slows graying, treats dandruff, and dry scalp. A comparative study published in 2015 shows that rosemary oil is effective in treating androgenetic alopecia (permanent balding) cases by boosting hair growth. At six months, a significant increase in hair count was noted for the group treated with rosemary oil. It also promotes healing by increasing microcirculation of the scalp and decreases hair loss after shampooing.
Enhances Brain Function
One of the earliest documented uses of rosemary for health reasons was as a cognitive stimulant. It helped improve memory performance and quality. It is also known to boost alertness, intelligence, and focus. One possible mechanism for this action is that rosemary extract enhances the synthesis of nerve growth factor which is vital for nerve tissue.
As per a research study published by Dr. Solomon Habtemariam, rosemary prevents beta-amyloid plaques and suppresses acetylcholinesterase (AChE) activities, which are associated with the symptoms of Alzheimer’s, ataxia and dementia. It has also been linked to stimulating cognitive activity in the elderly as well as those suffering from other acute cognitive disorders.
The carnosic acid in rosemary has neuroprotective properties. A 2016 study suggests that it helps to reduce oxidative stress and overstimulation in nerve cells, ultimately protecting the nervous system. There is also some evidence that rosemary protects certain parts of the brain from tissue damage such as ischemic injury, heals nervous tissue, and reduces blood clots.
Reduce Liver Damage
Rosemary has been used for its protective effect on the liver in traditional medicine. A 2015 animal study published in the Saudi Journal of Biological Sciences revealed that extracts of rosemary and olive leaves helped in reducing liver cirrhosis, likely due to their antioxidant activities.
A study conducted on the anti-depressant effects of rosemary concluded that the herb is effective in improving symptoms of depression, and these anti-depressant effects were observed even with repeated administration two weeks later. Rosemary may have a calming effect on those who suffer from chronic anxiety and depression. Furthermore, it reduces salivary cortisol (the stress hormone) levels, which helps ease tension in the body.
Carnosol in rosemary decreases androgen receptor expression and also disrupts estrogen receptors in cancer cells. It also lowers the release of DHT (dihydrotestosterone) hormone, which helps improve prostate health and enhance hair growth.
The Nutrition and Cancer journal has published a study in 2015, which suggests that rosemary extract is very helpful in treating cancer.
Carnosol, rosmarinic acid, carnosic acid, and other rosemary extracts have antioxidant, anti- , antiproliferative, and anticancer properties. They selectively kill cancer cells. It has shown promising results in the treatment of various cancers including colon, blood, breast, prostate, ovarian, cervical, liver, lung, bladder, and pancreatic cancer.
The antioxidants in the essential oils of rosemary help improve the quality of the skin. It has a potent anti-aging effect and helps heal blemishes and increase the natural shine. Also, its extracts with citrus supplements prevent skin against UV light damage, much better than the supplements alone.
In a research study on the effects of rosemary extracts on skin damage, Dr. Alice L. Pérez Sánchez states that the herb actually helps protect you against UV-induced damage through its antioxidant effects.
Limits Weight Gain
The herbal extracts exert anti-inflammatory and anti-hyperglycemic effects and promote weight loss. Treatment with rosemary extract resulted in significant weight loss and increased fecal excretion of lipids. According to another study, carnosic acid-rich rosemary can be used as a preventive treatment for metabolic disorders.
Antibacterial & Antimicrobial
Rosemary is specifically powerful against bacterial infections. It is linked to preventing staph infections, which are highly contagious and can cause lethal boils and blisters. It also eradicates various gram negative and gram positive bacteria completely.
Prevents Blood Clot
Due to its abundant antioxidant profile, rosemary has an anti-thrombotic effect and helps prevent blood clots.
Due to itsqualities already discussed, rosemary intake has been shown to prevent the growth of H. pylori bacteria, a dangerous pathogen that is associated with gastritis, stomach ulcers, and some cancers.
The active components in rosemary are antioxidant, anti-inflammatory, and anti- in nature. This represents a three-pronged attack against many different diseases and pathogens that could threaten the immune system or damage the integrity of the body.

Stimulates Blood Flow
Research published in the African Journal of Traditional, Complementary and Alternative Medicine showed that hematological parameters improved after treatment with rosemary extract as well as lipid peroxidation levels. Rosemary acts as a stimulant for the body and boosts the production of red blood cells and blood flow.
As an analgesic substance, rosemary is topically applied to the affected area to soothe the pain. When consumed orally, it acts as a pain reliever potentially helping with headaches, migraines, menstrual and stomach cramps, as well as kidney pain.
Carnosol and carnosic acids are two powerful antioxidants and anti-inflammatory compounds found in rosemary that have been linked to reducing inflammation of muscles, blood vessels, and joints. This makes it an effective treatment and prevention of many diseases, including , gout, arthritis, and injuries sustained during physical exertion or surgery. It is effective in oral or topical form. Furthermore, the reduction in inflammation in the system can help boost heart health and prevent atherosclerosis.

Rosemary is slightly diuretic in nature, meaning that it can help flush out toxins efficiently during urination. Furthermore, by increasing the rate at which water leaves the body, it can also help push out pathogens, salts, toxins, and even excess fat when consumed regularly. Rosemary has also been shown to have hepatoprotective effects; protecting the liver so it can do its job of detoxifying the body.
Rich Source of Antioxidant
Antioxidant compounds in rosemary make a secondary line of defense behind the body’s own immune system. Rosemary contains a significant amount of antioxidants including rosmarinic acid, caffeic acid, betulin acid, and carnosol.
The presence of carnosic acid helps to prevent age-related macular degeneration, which affects the outer retina of the eye.
Cineole in rosemary oil, taken either orally or via inhalation, boosts body activities by enhancing locomotion, according to a study.
