Top 10 Herbs for Mental Energy
to the medical experts, the brain is
supposed to be the most important and sensitive part in a human body. Many of
the drugs, pollutions and other health conditions make negative affects on the
brain cells. These toxins need to be removed and cleared so that the brain can
get the power to work well.
According to the Alzheimer's
Association's 2011 Alzheimer's Disease Facts and Figures, 5.4
million Americans -- including one in eight people aged 65 and over -- live with Alzheimer's

steady loss of both intellectual and social skills, and, ultimately, premature
at the National Brain Research Centre (NBRC), have conducted studies on mice
and suggested that ashwaganda extract may reverse memory
improve cognitive abilities in those suffering from Alzheimer's disease.
Initially, mice with Alzheimer's were unable to learn or retain what they
learned, but after receiving ashwaganda for 20 days, this improved
significantly. After 30 days, the behavior of the mice returned to normal.
A reduction in amyloid plaques (amyloid plaques, along
with tangles of nerve fibers, contribute to the degradation of the wiring in
Improved cognitive abilities. Rather than impacting the brain
directly, researchers found that the herb worked by boosting a protein in the
liver, which enters the bloodstream and helps clear amyloid from the brain.
known as Bacopa monnieri in Latin and Bacopa in English, is a potent Ayurvedic
herbs is used by practitioners of Ayurvedic medicine to treat various disorders
related to brain. Brahmi
contains active constituents such as heraponin and bacosides, which are known to
help in improving the transmission ability of nerve cells to the brain. It has
been found to be effective in treating brain related disorders such as mental fatigue, dementia,
poor memory, psychosis, epilepsy, neuralgia, and depression.
To brew Brahmi tea, add 10-12 Brahmi leaves and a teaspoon of dry Amla powder to
a cup of water and boil it. Also be added to salads and soups as garnish.
study conducted in cell culture showed that Gotu Kola herb reduces an oxidant
known as nitric oxide, which is triggered by the build-up in the brain of beta-amyloid
plaques associated with Alzheimer's. A study published
this year in the International Journal of Alzheimer’s Disease offered a
tantalizing view of the possible brain protective properties of gotu kola.
Researchers administered a water based extract of gotu kola to Tg2576 mice, a
mouse model of Alzheimer’s disease that has increased levels of beta-amyloid
protein. Beta-amyloid is a protein that is elevated in the brains of Alzheimer’s
disease patients, where it tangles and forms plaques that disrupt brain
function. Gotu kola impacts the effects of excess beta-amyloid using an unusual
and as yet unknown mechanism. Because of its distinct way of protecting from
beta-amyloid, the authors of this study suggest that gotu kola might be a
valuable complementary agent when used alongside current or new Alzheimer’s
The seeds contain more caffeine than any plant in the world, with levels ranging
from 2 percent to 8 percent. The plant also contains the stimulants theobromine
and theophylline. Caffeine
works by stimulating the central nervous system (CNS), heart, and muscles. The
stimulatory effect of guarana is more gradual and sustained than caffeine due to
the caffeine-tannin complex. Guarana is generally regarded as safe when not
combined with other stimulatory agents, such as ephedra.
A acts as a cholinesterase inhibitor — a type of medication that works by
improving the levels of neurotransmitters in the brain. Small early studies
suggest that huperzine A may improve memory and protect nerve cells, which could
slow the cognitive decline associated with Alzheimer's. In China, Huperzine A is
used to treat patients with Alzheimer's disease and myasthenia gravis.
Scientists have studied the effects of this alkaloid substance on the mental
functions of elderly Alzheimer's patients with successful results.
In a strictly controlled experiment rigorously designed by experts, patients
with ages ranging from 52 to 80 were used as subjects. All 60 patients have one
or more impaired faculties as a result of the action of acetylcholinesterase.
Two groups were treated using 200 mg of synthetic Huperzine A daily in either
capsules or tablets while the other group was given placebo. The experiment
lasted for 60 days and afterwards, during the evaluation using an array of both
psychological and physiological tests, improvement rates in both groups ranged
from 43% to 70%. No statistical evidence was found that significantly marked the
difference between the capsule group and the tablet group. This led the
scientists to conclude that Huperzine A may have very positive effects on the
cognitive aspects of the human brain.
Huperzine A is good not just for the old, geriatric people, but for the young as
well. In another study designed to examine the effects of Huperzine A on the
mental functions of adolescents, Chinese researchers found that the compound can
enhance memory and learning in young adults. The Alzheimer's Association
recommends that you not take huperzine A if you're already taking a prescribed
cholinesterase inhibitor, such as donepezil (Aricept), rivastigmine (Exelon) or
galantamine (Razadyne). Taking both could cause side effects, such as nausea,
vomiting, diarrhea, dizziness and muscle
Consult with your doctor before starting any dietary supplement, including
balm: A relative of the mint family, it grows
to about one metre and its leaves are usually hairless and bright green.
Researcher Dr David Kennedy found that healthy young adults given capsules
containing doses of the plant's dried leaves were significantly better at
standardized computer memory tests than those who took a placebo. They also
scored higher in another standard test that measured calmness. They found that
the higher the dose, the bigger the effect on both memory and mood. Meanwhile,
Elaine Perry of the Medical Research Council's unit at Newcastle General
Hospital found lemon balm (Melissa
had a positive effect on pieces of brain tissue and chemical receptors in the
brain affected by Alzheimer's. In
another study conducted by scientists from the Human Neuroscience Unit,
University of Northumbria, 20 healthy volunteers received Melissa supplements
(at increasing doses of 300mg, 600mg and 900mg) or placebo. Tests to evaluate
the participants' memory scores were conducted at hourly intervals. The
scientists found significant improvements in both attention span and memory
function in the group taking the Melissa supplements. This improvement was
dependent on the specific dosage amount received; with lower doses promoting
calmness and the highest dose reducing alertness.
come in several varieties, all highly sought after by collectors, yet easy to
grow and very hardy. Named
for the mythical Greek figure Paeon, who was said to be a student of the
illustrious physician Aesculapius. Peony root has been used as a diuretic,
sedative, and tonic, and is known for its antispasmodic, analgesic, and
anti-inflammatory effects. The ancient Greeks used it to treat epilepsy. Chinese
scientists recently discovered three new glycosides in peony, including a unique
monoterpenoid glycoside called paeoniflorin, which calms nerves and alleviates
muscle spasm. Even more exciting is the Japanese discovery of paeoniflorin’s
ability to improve memory in animal studies, suggesting a potential benefit for
fact, paeoniflorin is effective at doses as low as the equivalent of an adult
person consuming only 700 micrograms daily. This is less than one milligram a
day. Here is what scientists do know about peony extract:
Stimulates the hippocampus—which is in the brain’s temporal lobe, and is
responsible for storing new information—to enhance learning and memory. This is
significant because in humans Alzheimer’s disease and other forms of dementia
affect the hippocampus first, before other parts of the brain.
Ameliorates spatial cognitive impairment in animals given an amnesia-producing
Exerts a protective effect on brain neurons in animals during epileptic
Improves the ability to learn in animals with age-related learning deficits.
The scientists concluded that peony has the therapeutic potential to treat
senile dementia and aging-induced cognitive dysfunction.
from Northumbria University in the United Kingdom found that the amount of
1,8-cineole, a main chemical in rosemary oil, in the blood is linked with brain
performance. Their work was published in the journal Therapeutic Advances in
Psychopharmacology. The researchers exposed 20 people to different levels of
rosemary oil aroma, and then took blood samples to see how much of the
1,8-cineole each person absorbed. Then, the participants took speed, accuracy
and mood tests to see if the rosemary oil had any effects. They found that the
more 1,8-cineole in the bloodstream of the person, the better the person's
performance on both the speed and accuracy tests. Researchers also noted a small
effect on mood. This isn't the first research to link rosemary scent with
memory. A 2003 study in International Journal of Neuroscience, also conducted by
the researchers at the University of Northumbria, showed that rosemary is linked
with "an enhancement of performance for overall quality of memory and secondary
memory factors," though it was also linked with a decreased memory speed
compared to the control group in that study.
In 1597, herbalist John Gerard proclaimed sage was "singularly good for the head
and quickeneth the nerves and memory". In one of the few clinical trials
looking at sage's ability to improve memory, healthy, young adults who had taken
sage oil capsules performed significantly better in a word recall test. The
study -- funded by Oxford Natural Products -- appears in the latest edition of
the journal Pharmacology, Biochemistry and Behaviour. In the study from
researchers at the Medicinal Plant Research Centre, 44 healthy, young adults
took either sage oil capsules or a placebo. The participants then took a series
of word recall tests. The people who had taken the sage oil consistently had
better word recall -- a sign that sage may help improve memory. The
exact cause of AD is unknown, but some physicians believe an accumulation of
aluminum in the brain, or a defect in the production of a brain chemical called
acetylcholine (involved with short-term memory) is the cause. Sage is believed
to bind to specific receptors in the brain and imitate the action of
antioxidant and anti-inflammatory properties could be valuable in Alzheimer's
rosea): Russian research indicate that rhodiola reduces stress and fatigue;
improves memory; enhances concentration and physical fitness; and increases
overall well-being. Better yet, rhodiola stimulates the immune
enabling the body’s own defenses to ward off the effects ofstress.
In one double-blind pilot study, students were given rhodiola or a placebo just
before taking exams. After 20 days, the rhodiola group showed improvement in
their physical fitness, coordination and mental sharpness. The recommended daily
dose is 100 mg of a rhodiola supplement standardized to contain 3 percent
