A common grass is promising to stimulate brain health and fight against Alzheimer’s disease

Rosemary (Rosmarinus officinalis), aromatic grass from the Mediterranean, has long been precious in kitchens around the world. But beyond its culinary charm, rosemary is also gauge For its impressive health benefits, especially with regard to brain health, inflammation and immune function.

The research suggests Rosemary can even make the promise In the fight against Alzheimer’s disease, the main cause of dementia in the world.

Historically, rosemary was linked to memory and mental clarity. In ancient Greece and RomeStudents and academics used rosemary in the hope of sharpening concentration and recall.

Modern science finds that there may have been something: in a studyPeople who inhaled Rosemary’s perfume better performed on memory tasks compared to those of an unfladumed environment.

So how does rosemary work on the brain? There are several mechanisms at stake. To start, Rosemary stimulates Blood circulation, including the brain, helping to provide more oxygen and nutrients, which can improve mental clarity. It also has soothing properties; Some studies suggest Its aroma can reduce anxiety and improve sleep. A lower constraint can mean Best concentration and retention of memory.

Rosemary contains compounds that Interact with brain neurotransmitters. One of these compounds, 1.8-cineole, Help to prevent ventilation Acetylcholine, an essential brain chemical for learning and memory. By preserving acetylcholine, rosemary can help support cognitive performanceEspecially as we age.

Another bonus? Rosemary is Packed with antioxidantswhich help protect brain cells from damage caused by oxidative stress – a major factor in cognitive decline.

Rosemary is rich in phytochemicals, plant compounds with effects improving health. One of the most powerful is carnosic acidan antioxidant and anti-inflammatory agent that Helps protect the brain cells from prejudiceIn particular from the types of damage linked to Alzheimer’s disease.

In 2025, Researchers have developed A stable version of carnosic acid called Diacca. In promising preclinical studies, this compound has improved memory, stimulated the number of synapses (connections between brain cells) and reduces the related proteins of harmful Alzheimer as the amyloid-bêta and the Tau.

What is particularly exciting is that Diacca is only activated in the regions of the inflamed brain, which could minimize side effects. Until now, studies on mice have not shown any sign of toxicity and significant cognitive improvements – to raise the hope that human trials could be the next.

Researchers also believe that Diacca could help deal with other inflammatory conditions, such as type 2 diabetes, cardiovascular disease and Parkinson’s disease.

Beyond brain health

The advantages of rosemary could extend well beyond the brain. It has been traditionally used to facilitate digestion, relieve bloating and reduce inflammation.

Compounds like romance acid and ursolic acid are known for their anti-inflammatory effects throughout the body. Rosemary can even benefit the skin – A review suggests It can help soothe acne and eczema, while carnosic acid can offer anti-aging advantages by protecting the skin from the sun damage.

Rosemary Also has antimicrobial properties, which is promising in preserving food and potential pharmaceutical applications by inhibiting the growth of bacteria and fungi.

For most people, rosemary is sure when used In food, teas or aromatherapy. But concentrated doses or extracts may present risks. Consume large quantities Can cause vomiting or, in rare cases, convulsions – especially in people with epilepsy.

There is also a theoretical risk Rosemary stimulating uterine contractions, the speakers should therefore avoid high doses. Because Rosemary can interact with certain drugs – like anticoagulants – It is preferable to check with a health care provider before taking large quantities in the form of a supplement.

Rosemary is more than just a must in the kitchen. It is a natural remedy with old roots and modern scientific support. While research continues, in particular in revolutionary compounds like the Diacca, rosemary could play an exciting role in future treatments for Alzheimer’s disease and other chronic affections.

In the meantime, adding a little rosemary to your life – whether in a meal, a cup of tea or a puff of its fragrant oil – could be a small step with great health benefits.
