Studies have found ginseng to
yield promising results when used as a form of treatment for memory
impairment. In the studies conducted, mice given dosages of ginseng
extracts showed remarkable improvements in water maze tasks. Ginseng was
shown to activate neurotransmitter activities that promote memory
enhancement.

3. Rosemary

Traditionally, this aromatic
herb has long been used to improve memory. Like gingko, rosemary has
been shown to contain antioxidants that neutralize free radicals. When
used in aromatherapy, rosemary has also been found to reduce cortisol
levels in the brain, thereby reducing anxiety. Furthermore, when
combined with other essential oils, rosemary has been shown to alleviate
stress and increase concentration and memory of graduate nursing
students.

4. Sage

Studies have found that sage
contains active ingredients that boost the chemicals that trigger
transmission of messages within the brain. Scientists from the
Universities of Newcastle and Northumbria also tested the herb on 44
people. Half the group were given sage, while the other half were given a
placebo. Results showed that those who were given sage performed better
in a word recall test.

5. Green Tea
|
|
Green tea is best known for
its antioxidant properties. Scientific research conducted in March 2013,
confirmed that green tea extracts help shield proteins and lipids (fat
soluble vitamins: A, D, E and K) from age associated activities caused
by oxidation. In the study, animals treated with green tea extracts
showed better spatial learning abilities. Furthermore, studies suggest
that the plant can protect the hippocampus (the part of the brain
responsible for emotion, memory and the autonomic nervous system) from
age-related decline.

for enhancing memory. In fact, it is considered to be one of the best
herbs to do so. Studies have also discovered that rhodiola not only has
the ability to improve one's focus and memory, it can also relieve
depression. Furthermore, researchers believe that this herb contains
adaptogenic qualities which stimulate the central nervous system of the
body, resulting in enhanced memory and concentration. Another study also
found that taking rhodiola regularly increases memorization abilities.

system of natural healing) to enhance learning, concentration and
memory. Numerous studies conducted on bacopa found it to be an effective
herb in improving one's memory and mental function. In one study,
conducted in Australia, 46 volunteers aging from 18 to 60 were divided
into two groups. In one group, each volunteer was given 300mg of bacopa
everyday. After 12 weeks, the subjects' verbal learning abilities, speed
of information processing, and memory significantly improved.
