A herbal tea for the brain.

When your brain isn’t ‘firing’ and is feeling a little ‘foggy’, it can be tempting to have a coffee or tea.  These caffeinated beverages may help initially, however their effects are short-lived quickly making it harder to concentrate, focus and learn.

There is an alternative.  Herbal tea is caffeine free and can be blended to contain specific memory boosting herbs to help you stay focussed.  Even better, the effects of these herbs can increase further when used regularly.

A tea that actually improves memory, concentration and ability to learn without the negative effects of caffeine, may sound too good to be true.  However, clinical trials are showing that many herbs with a long history of traditional use for improving brain function, do in fact have a significant effect on enhancing cognition.  The herbs are Gingko and Brahmi may be beneficial, as well as common culinary herbs Sage and Rosemary.

These herbs function best the longer they are taken, with most trials suggesting best effects after 4 to 6 weeks of daily consumption.  So why don’t you swap your daily coffee for a more healthy and effective herbal memory boost.

Herbs to stimulate mind and body

Gingko (Gingko biloba) is the world’s oldest living tree species and can be traced back more than 200 million years.  It is believed to offer the most benefit to the brain, nerves and blood vessels.  It also assists blood flow by promoting vasodilation and prevents platelet coagulation, a cause of clots[9].  Most notably however, Gingko improves learning and memory.  A 12 week trial comparing Gingko supplementation to placebo in patients with dementia and cognitive impairment found that Gingko significantly improved cognition, as well as the mood and emotions of the patients[1].  Numerous studies have also been done on Gingko supplementation in healthy people, most of which have shown positive outcomes in concentration and memory, generally over a 6 week period[9].  Gingko’s modes of action are thought to be via improving cerebral blood flow, preventing acetylcholine degradation and via its antioxidant properties[4,[9].

Brahmi (Bacopa monnieri) has been traditionally used in Indian Ayurvedic medicine since the 6th century for brain function, epilepsy and insomnia.  Brahmi is mostly known for its ability to enhance brain function, which is supported by a number of studies and clinical trials.  One double-blind clinical trial showed that 300mg daily over 12 weeks significantly improved cognitive function, memory and learning rate, as well as reducing anxiety[2].  Another study in mice found positive effects on learning and memory after only 3 days of supplementation[3].  The mechanism by which Brahmi improves cognition has been deduced in studies to be via its antioxidant and anticholinesterase activities[4].

Rosemary (Rosmarinus officinalis) acts as an antioxidant, protects the liver and is beneficial for memory function[5],[9].  Adults exposed to rosemary oil for 3 minutes were shown in a study to be more alert and relaxed.  The increase alertness was believed to be due to a measured decrease in frontal alpha and beta brain function, which increased alertness[6]. 

Sage (Salvia officinalis) has been used since medieval times to improve memory and as a treatment for dementia.  A clinical study on Alzheimer’s patients found sage (Salvia officinalis) to be effective for improving cognition[7], whilst two other clinical trials showed that a different species of sage (Salvia lavandulaefolia) improved cognition in healthy young adults[8].  Sage also has antioxidant, antimicrobial, astringent and antispasmodic properties[9]. 

Lemon balm (Melissa officinalis) was first documented as being used in the 17th century, where it was said to improve the mood and stimulate clear thinking[9].  Clinical trials support these traditional uses, as they show Lemon balm may help reduce anxiety in severe dementia[10] and improve memory performance and calmness in Alzheimer’s disease patients[11].
