Rosemary has been shown to benefit the brain in several ways

And research published this year suggests it could even help in the fight against Alzheimer's disease - the leading cause of dementia worldwide.
Rosemary has previously been linked to memory and mental clarity.
In ancient Greece and Rome, students and scholars used rosemary to sharpen concentration and recall, says Dipa Kamdar, senior lecturer in pharmacy practice at Kingston University.
Writing for The Conversation, she explains: "Modern science is finding there may have been something in this: in one study, people who inhaled rosemary's scent performed better on memory takes compared to those in an unscented environment."
There are several ways rosemary benefits the brain, says Kamdar.
Firstly, it stimulates blood circulation, including to the brain, helping deliver more oxygen and nutrients, which may improve mental clarity.
It also has calming properties, with some studies suggesting its aroma can reduce anxiety and improve sleep - lower stress means better focus and memory retention.
Kamdar adds: "Rosemary contains compounds that interact with the brain's neurotransmitters. One such compound, 1,8-cineole, helps prevent the breakdown of acetylcholine, a brain chemical essential for learning and memory. By preserving acetylcholine, rosemary may help support cognitive performance, especially as we age."
And rosemary's antioxidants may also help protect brain cells from damage caused by oxidative stress - which is a major factor in cognitive decline.
Kamdar says: " Rosemary is rich in phytochemicals, plant compounds with health-enhancing effects. One of the most powerful is carnosic acid, an antioxidant and anti-inflammatory agent that helps shield brain cells from harm, particularly from the kinds of damage linked to Alzheimer's disease."

As well as boosting brain health, studies suggest rosemary may aid digestion by stimulating the liver to produce bile, which helps the body digest fat.
In a study with mice, it was shown to reduce inflammation in the digestive tract, potentially aiding in the management of IBS and other inflammatory bowel ailments.
And rosemary supplementation may also positively impact the gut microbiota, increasing beneficial bacteria like Bifidobacterium and Bacteroidetes, while reducing harmful bacteria like Escherichia coli.
Rosemary may also be able to improve immune function.
Some studies, particularly in vitro and animal models, suggest that rosemary and its active compounds, like carnosic acid and rosmarinic acid, can influence immune function.
Other studies have shown rosemary may promote immune cell activity, such as increasing antibody production or enhancing the activity of immune cells like dendritic cells.
Finally, rosemary could prevent certain cancers.
Rosemary has been proven to display powerful anticancer efficacy in numerous cancers, including lung, prostate, liver, and breast.
Carnosic acid appears to be the plant's primary anticancer component, as it was found in one study to exhibit antiproliferative effects in cancer cells.

Other ways to reduce your Alzheimer's risk Be physically active Regular physical activity is crucial for overall health and may help reduce the risk of dementia, including Alzheimer's disease. Aim for at least 150 minutes of moderate-intensity activity per week. Eat a healthy diet A balanced diet, potentially including the Mediterranean diet, can help reduce your risk of dementia, as well as other health conditions. Stay mentally active Keeping your mind active can strengthen your brain's ability to cope with disease. Engage in activities like reading, learning new skills, or playing brain games. Manage other health conditions Maintaining healthy blood pressure, cholesterol, and blood sugar levels can also contribute to reducing your risk of dementia. Prioritise sleep Aim for seven to eight hours of quality sleep each night, as sleep deprivation can negatively impact brain health. Maintain good heart health Taking care of your heart health, including avoiding smoking and excessive alcohol consumption, can also lower your risk of dementia and other diseases. Seek medical advice If you have any concerns about your health or a family history of Alzheimer's, consult with a healthcare professional.

Over half of Brits feel lonely at least once a month… but are ashamed to admit it, study shows
Gen Z feels lonelier than any generation—yet hides it behind screens and silence daily NOT ALONE Over half of Brits feel lonely at least once a month… but are ashamed to admit it, study shows Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) OVER half of Brits feel lonely at least once a month – but are ashamed to admit it. A poll of 2,000 adults revealed 56 per cent would rarely or never consider talking to someone else about how isolated they felt. Sign up for Scottish Sun newsletter Sign up 2 The research was commissioned by audio brand, Pure Credit: SWNS Reasons for this included not wanting to burden others (37 per cent), not believing anyone else will understand (21 per cent), and not wanting to appear vulnerable (21 per cent). This may be a reflection on the strength of their support networks, as a quarter (24 per cent) described theirs as lacking – and a further 13 per cent didn't have one at all. Instead, those who feel lonely are likely to distract themselves through entertainment, such as watching TV (47 per cent), going on social media (22 per cent), or listening to the radio (19 per cent). The research was commissioned by audio brand, Pure, which is partnering with Marmalade Trust, a Bristol-based charity dedicated to raising awareness of loneliness and helping people build meaningful connections. As part of this partnership and in support of Loneliness Awareness Week, Pure will be donating 150 radios to individuals across the UK who are looking for support through a period of loneliness. Dr Lalitaa [COR], behaviouralist psychologist and expert in emotional wellbeing, commented: 'Loneliness remains a taboo subject, often shrouded in shame and stigma. 'But human connection is a basic psychological need – one that's increasingly difficult to fulfil in today's fast-paced, digital world. 'It's encouraging to see initiatives like this that provide simple, tangible comfort and help people feel part of something again.' Tara Fisher, COO from Marmalade Trust added: "Loneliness is a natural human emotion that we are all likely to experience in our lifetime. 'But there is still a stigma around loneliness, which means a significant portion of the population are reluctant to speak about these feelings to others – either because they don't feel they have anyone to talk to or are worried about doing so.' Despite these feelings of shame around loneliness, nearly eight in 10 (79 per cent) acknowledged it as a common phenomenon among the general population. Women were also found to feel lonelier than men – with only 16 per cent of women saying they never feel lonely, compared to 26 per cent of men. But perceptions about the generations most affected were not entirely accurate – with 19 per cent of all respondents believing the Silent Generation (born 1928-1945) is impacted the most by loneliness. However, Gen Zs (born 1996-2011) specifically reported feeling lonelier than any other age group, with one third feeling this way a few times a week and 11 per cent even experiencing this every single day. This compares to 19 per cent of the whole population dealing with this a few times a week and only six per cent every day. Worries about being judged (25 per cent) and dismissed (21 per cent) were also higher among Gen Zs – as were desires to socialise more (53 per cent) and make more friends (42 per cent). This compares to the 'famously lonely' Silent Generation – four in 10 of whom reported usually only going an hour maximum without speaking to someone else. A fifth of all those asked agreed on one day as the limit for not speaking to another person before feeling lonely – yet 23 per cent go this long, or longer, without talking to anyone regularly. Regionally, Londoners were most likely to report feeling lonely – with 33 per cent of those living in the capital saying they feel lonely at least a few times a week. Nearly four in 10 (39 per cent) of all respondents also claimed to feel lonelier now than they did five years ago, primarily because it's now harder to meet people. Other reasons included changes in personal relationships (23 per cent), financial stress (22 per cent), and lower self-esteem (20 per cent). The top locations people reported feeling lonely were also established as at home alone (59 per cent), in a crowd (27 per cent), and when having a meal by themselves (26 per cent). Perhaps to stave off this lonely feeling, over half (52 per cent) are more likely to listen to the radio when at home alone, according to data. Other than listening to the news and their favourite music, 38 per cent utilise their broadcast boxes for background noise (38 per cent), company (20 per cent), and making the house feel less quiet (19 per cent). A further 16 per cent specified listening to the radio helps them to feel less lonely, with 15 per cent liking to hear the sound of other people's voices, and 13 per cent enjoying being part of the conversation. Stations providing the best company were also identified as pop music (30 per cent), oldies music (24 per cent), and talk radio stations (21 per cent). Hubert Eiter, spokesperson for Pure, which is donating £5 for every Pure radio sold between June 9 – July 9, 2025 in support of Marmalade Trust, said: 'Pure has been active in supporting loneliness charities over many years and we are proud to partner with the Marmalade Trust this year. 'It's great to see that everyday listening can bring a lot of comfort to people, as it has the power to immediately make a room feel livelier and less quiet – we love the fact that radio is able to provide some company for those who feel lonely from time to time.'
