Rosemary (Rosmarinus officinalis)  has been hailed since ancient times for its medicinal properties. It was traditionally used to help alleviate muscle pain, improve memory, boost the immune and circulatory system, and promote hair growth. Recent research has confirmed that this herb has a wide range of health benefits.

The leaves are often used as a seasoning in a variety of dishes, such as soups, casseroles, salads, and stews.; rosemary not only tastes good in culinary dishes, such as rosemary chicken and lamb, but it is also a good source of iron, calcium, and vitamin B-6.

Possible health benefits include improved concentration, digestion, and brain aging.

Antioxidants and anti-inflammatory compounds

Rosemary is a rich source of antioxidants and anti-inflammatory compounds, which are thought to help boost the immune system and improve blood circulation. Antioxidants play an important role in neutralizing free radicals.The antioxidant and anti-inflammatory activity of rosemary is largely attributed to its polyphenolic compounds like rosmarinic acid and carnosic acid. This latter is believed to fight off  free radical damage  in the brain.

Improving digestion

In Europe, rosemary is often used to help treat indigestion. In fact, Germany’s Commission E has approved rosemary for the treatment of indigestion.

Enhancing memory and concentration and providing neurological  protection

Some studies in rats have identified that rosemary might be useful for people who have experienced a stroke. Rosemary appears to be protective against brain damage and might improve recovery.

Even its aroma seems to have a positive effect on brain function. According to research outlined in Therapeutic Advances in Psychopharmacology, the aroma from rosemary can improve a person’s concentration, performance, speed, and accuracy and, to a lesser extent, their mood.

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.

Prevent brain aging

Some studies have suggested that rosemary may significantly help prevent brain aging. The therapeutic ability of rosemary for prevention of Alzheimer’s shows promise, but more studies are needed.

Cancer

Research published in Oncology Reports found that “crude ethanolic rosemary extract (RO)” slowed the spread of human leukemia and breast carcinoma cells.”

Another study, published in Bioscience, Biotechnology and Biochemistry, concluded that rosemary might be useful as an anti-inflammatory and anti-tumor agent.

Also, a report published in the Journal of Food Science revealed that adding rosemary extract to ground beef reduces the formation of cancer-causing agents that can develop during cooking.

Protection against macular degeneration

A study published in the journal Investigative Ophthalmology & Visual Science, led by Dr. Stuart A. Lipton, Ph.D. and colleagues at Sanford-Burnham Medical Research Institute, revealed that a carnosic acid, which is a major component of rosemary, can significantly promote eye health.

Animal studies have found that adding rosemary extract to other oral treatments can slow the progression of age-related eye diseases.

One study examined the addition of rosemary extract to common treatments like zinc oxide and other AREDs antioxidant combinations, finding that it helped slow age-related macular degeneration.

Antimicrobial properties

The compounds in rosemary may also have antimicrobial properties, which may help fight infections. Rosemary leaves are employed in traditional medicine for their antibacterial and wound healing effects.

Effect on Blood Sugar Levels

Some studies have shown that compounds in rosemary  may lower blood sugar, suggesting that rosemary could have potential applications for managing high blood sugar among people with diabetes.

Test-tube and animal studies on rosemary indicate that carnosic acid and rosmarinic acid have insulin-like effects on blood sugar. It has been suggested that these compounds can increase the absorption of glucose into muscle cells, lowering blood sugar.

May benefit heart health. 

One animal study found that rosemary extract reduced the risk of heart failure following a heart attack

Caution:

Rosemary is usually safe when taken in low doses. However, extremely large doses can trigger serious side effects, although this is rare.High doses of rosemary may cause miscarriage; therefore it is not advisable for pregnant women to take any supplemental rosemary.

Drug interactions :Rosemary can affect the activity of some medications, including:

• Anticoagulant drugs: These include blood-thinning medications, such as Warfarin, Aspirin, and Clopidogrel.
• ACE inhibitors: These are used for treating high blood pressure. They include lisinopril (Zestril), fosinopril (Monopril), captopril (Capoten), and enalapril (Vasotec).
• Diuretics: These increase the passing of urine and include hydrocholorothiazide and furosemide (Lasix).
• Lithium: This is used to treat the manic episodes of manic depression. Rosemary can act as a diuretic and cause lithium to reach toxic levels in the body.
