Certain herbal teas improve memory or mood
For a long time, people have been using herbs to treat certain diseases or to influence their mood. Researchers have now found that some herbs and herbal teas can produce significant benefits in emotional mood and memory in older people.
In their research, scientists at Northumbria University found that the herbs peppermint, chamomile, rosemary and lavender affect mood and memory. This leads to considerable advantages, especially for older people. The doctors released a press release on the results of their study.
What do different herbal teas do?
Drinking peppermint tea, for example, improves attention. In contrast, chamomile tea has a calming effect, say the experts. Flavors like rosemary and lavender can affect memory in people over 65 years of age. Rosemary improves the memory, while lavender affects the memory, the doctors add.
Experts examine effects of tea consumption in 180 subjects
The researchers examined 180 volunteers for their study. They either took tea with chamomile or peppermint. After consumption, the subjects' cognition and mood were examined. In addition, there was a control group that only consumed hot water, explain the doctors.
Peppermint improves long-term memory
The scientists found that peppermint can improve mood and cognition. This also leads to an improvement in long-term memory and increased attention. In contrast, chamomile has a calming effect, which worsens our attention and memory, the experts say.
Scientists are also studying the effects of certain flavors
In a separate study, 150 healthy people over the age of 65 were exposed to the scent of essential oils of rosemary and lavender in a control room. In addition, there was a control group, which were not exposed to essential oils. Afterwards, the participants were asked to perform certain memory tests, the authors explain. The mood of the test subjects was also checked.
Rosemary aroma significantly improves memory
Participants from the room with the rosemary scent showed a significantly improved memory, with 15 percent better test results than the subjects from the room without the rosemary aroma. The rosemary scent also led to improved attention, say the doctors.
Lavender scent soothes
If participants had spent the time in a room with a scent of lavender, this led to a marked increase in inner peace and contentment. However, the ability to remember to perform certain activities at a certain time decreased.
Peppermint tea also improves long-term memory
Peppermint is psychologically and mentally stimulating. Peppermint wakes you up and improves attention, says author Dr. Mark Moss from Northumbria University. The tests should check whether these positive effects are also produced when consuming peppermint tea. The study found that peppermint tea users had a better long-term memory. Affected people could remember more words and pictures that they had seen before, the author adds.
Rosemary improves the memory of people over the age of 65
It has long been said that rosemary affects our memory. When subjects were exposed to rosemary aroma, the participants' attention improved. It has also been found in people over the age of 65 that rosemary can improve memory.
Identified effects are particularly strong in older people
It is interesting to see the different effects that the herbs can have on mood and memory, the authors say. The effects are particularly pronounced in older people. Research shows that there is an easy way to improve his memory, experts say.
