Rosemary: The Brain-Boosting Herb and Its Potential Benefits

Rosemary is a perennial herb native to temperate climates and belongs to the mint family. Its leaves are commonly used fresh or dried for cooking, food flavoring, medicine, and cosmetics. Although it has been used in folk medicine for centuries, scientists are only recently discovering its potential to combat dementia and improve brain health.

Rosemary: More than just a flavor enhancer

Rosemary has long been used for its culinary properties, such as: B. for seasoning steaks, potatoes, soups and stews. But its health benefits have also been recognized for centuries. The ancient Greeks used rosemary to clean wounds, treat infections, and as a tea to recover from fevers and other illnesses. Recent scientific studies have focused on the herb's potential cognitive benefits.

Rosemary and brain health

Rosemary is rich in various antioxidants that protect cells from damage caused by free radicals. Antioxidants have been shown to protect against certain types of cancer and heart disease by reducing inflammation and blood pressure (1). These benefits have been linked to improved brain function in older adults with memory problems such as Alzheimer's disease (AD).

A study of 28 older adults found that consuming a low dose of dried rosemary powder resulted in a statistically significant improvement in memory speed, while a higher dose did not produce the same results (2). Other studies have examined the influence of rosemary aroma on cognitive performance.

The effects of aroma on cognition

In one study, participants were exposed to rosemary aroma while performing visual processing tasks and serial subtraction tasks. The more aroma they were exposed to, the greater the improvement in task speed and accuracy (3). Another study of 53 young teenagers showed that students' memory improved when rosemary essential oil was sprayed in the room. A similar study with 40 school children produced comparable results (4).

Rosemary aroma and future memory

Memory can be divided into three types: past memories, current memories (minute by minute), and future memories (e.g. remembering to make a doctor's appointment). Improving future memory has proven to be a particular challenge for scientists (5). A research team in Northumbria tested this with a cognition test on 60 participants, either in a room scented with rosemary essential oil or in a room unscented. The rosemary group performed better, although not dramatically, suggesting that more research is needed to establish a definitive link between rosemary aroma and improved future memory.

Rosemary water and cognitive function

A separate study examined the effects of drinking rosemary water on cognitive function. Eighty adults were given either 250 ml of rosemary water or regular mineral water and their cognitive function was assessed. Participants who drank rosemary water showed minor improvements compared to those who drank regular mineral water (6).

Possible side effects and interactions

Rosemary is generally safe when consumed in small doses. However, high doses can cause side effects such as vomiting, convulsions, pulmonary edema (swelling), and in rare cases, coma. Pregnant women should avoid rosemary as it can cause miscarriage. Some possible drug interactions include (7):

• Antikoagulanzien: Blutverdünnende Medikamente wie Warfarin, Aspirin und Clopidogrel.
• ACE-Hemmer: Bluthochdruck-Medikamente wie Lisinopril (Zestril), Fosinopril (Monopril), Captopril (Capoten) und Enalapril (Vasotec).
• Diuretika: Medikamente, die die Urinausscheidung erhöhen, wie Hydrochlorothiazid und Furosemid (Lasix).
• Lithium: Wird verwendet, um manische Episoden einer bipolaren Störung zu behandeln.

• Lithium: Rosmarin kann als Diuretikum wirken und möglicherweise dazu führen, dass Lithium im Körper toxische Werte erreicht.

Rosemary, a natural herb, can provide more than just a flavor boost to meals; It may also provide brain health benefits. However, it is important to consult a doctor before introducing any form of rosemary into your routine. This is especially important for pregnant women or people taking other medications. If you notice any side effects, stop use immediately and consult your doctor.

Dementia and memory loss statistics and brain health tips

Dementia is a growing problem worldwide. According to the World Health Organization, around 50 million people worldwide suffer from dementia, with almost 10 million new cases every year. Alzheimer's disease accounts for 60-70% of dementia cases. As the world's population ages, the number of people affected by dementia is expected to increase.

To maintain brain health and potentially reduce your risk of dementia or memory loss, consider the following tips:

1. Betreiben Sie regelmäßig körperliche Aktivität: Es hat sich gezeigt, dass Bewegung die Gesundheit des Gehirns verbessert und dazu beitragen kann, kognitiven Verfall zu verhindern.
2. Achten Sie auf eine gesunde Ernährung: Eine ausgewogene Ernährung, die reich an Obst, Gemüse, Vollkornprodukten, magerem Eiweiß und gesunden Fetten ist, kann die Gehirnfunktion unterstützen.
3. Holen Sie sich ausreichend Schlaf: Schlaf spielt eine entscheidende Rolle für die allgemeine Gesundheit, einschließlich der Gesundheit des Gehirns. Streben Sie jede Nacht 7-9 Stunden guten Schlaf an.
4. Bleiben Sie sozial engagiert: Geselligkeit mit Freunden, Familie und Gemeindemitgliedern kann dazu beitragen, die kognitive Funktion und das geistige Wohlbefinden zu erhalten.
5. Nehmen Sie an geistig anregenden Aktivitäten teil: Aktivitäten wie Puzzles, Lesen, das Erlernen einer neuen Fähigkeit oder das Spielen eines Musikinstruments können helfen, das Gehirn scharf zu halten.
6. Stress bewältigen: Chronischer Stress kann sich negativ auf die Gesundheit des Gehirns auswirken. Praktiziere stressreduzierende Techniken wie Achtsamkeit, Meditation, Yoga oder Atemübungen.
7. Überwachen und behandeln Sie chronische Erkrankungen: Erkrankungen wie Diabetes, Bluthochdruck und hoher Cholesterinspiegel können das Risiko eines kognitiven Verfalls erhöhen, wenn sie nicht richtig behandelt werden.

Keep in mind that while rosemary may have potential cognitive benefits, maintaining overall brain health requires a comprehensive approach, including a healthy lifestyle and regular checkups with your doctor.
