Dementia: Peppermint tea improves working memory

Dementia is a looming crisis in much of the developed world with an aging population. In addition to strengthening the health system, there is another way to protect against the wind: strengthening the brain against decline. Although there are no known ways to prevent dementia, progress is being made in understanding how to strengthen the brain.

Although it is not known whether peppermint tea protects against dementia, peppermint tea may improve memory.

Peppermint is an aromatic herb from the mint family. It tastes like peppermint, but smoother and sweeter.

That’s according to a study designed to evaluate three herbal teas — German chamomile, chamomile, and peppermint — and their effects on health issues important to women, including sleep, anxiety, and menstruation.

Commenting on the findings, Dr Gill Jenkins, GP, co-author of the study and guest advisor to the independent health and wellbeing group, the Tea Advisory Panel (TAP), said: ‘Among the herbal teas reviewed in this article, peppermint in particular was found to improve memory.

According to the doctor, the review “identified a study of 90 women and men with age-related memory decline and found that 900 mg of peppermint extract daily improved the quality of working memory by 15 percent and spatial memory by nine percent.”

Working memory is a small amount of information that can be stored in the mind and used to perform cognitive tasks.

Spatial memory is specifically related to storing and retrieving information in the brain, including planning a route to a desired location and remembering where an object is located or the location of an event.

“Trends of improved mood, alertness and behavior were also seen in this study,” Dr. Jenkins said.

He continued: “A human study of 142 women and men (ages 50-70) using 900 mg of peppermint extract daily showed that peppermint improved cognitive function.”

This finding is particularly noteworthy because, in addition to the obvious effects of dementia, the pandemic has damaged memory function.

Dr. Jenkins explained: “Many of us have suffered from a lack of social contact over the last couple of years, and our memories may have been further damaged by a lack of new experiences, events and dates.”

What else did the study show?

The review identified randomized controlled trials (RCTs) from a large international database of peer-reviewed scientific papers.

“Such trials were identified using specific search terms (ie, ‘herbal tea/infusion/tisane’, ‘chamomile tea/infusion/tisane’, ‘peppermint / peppermint tea/infusion/tisane’ and ‘rose hip/rose tea/ infusion” ‘/tisane’),” explained Dr. Jenkins.

He continued: “Because we wanted to assess mechanisms of action (ie, how teas might work – rather than whether they work on different health issues) we also identified studies of tea and tea extracts conducted in laboratories.

“Studies like this can really determine how teas and their ingredients can affect specific parts of the body, as well as the whole body.”

According to the doctor, the general results of the RCT review show that chamomile improves sleep and reduces anxiety.

“Improved sleep and anxiety improve brain function (due to better rest), so we can conclude that chamomile tea indirectly improves brain function, but the immediate effect of chamomile is calming without any effect on memory,” he says. noted.

According to Dr. Jenkins, chamomile can increase the brain’s neurotransmitters (serotonin, dopamine, and norepinephrine) and thus have a positive effect on mood and anxiety.

“There is also evidence from laboratory studies that Rosehip improves spatial memory.”
