INTRODUCTION
In modern
world, people are more often exposed to environmental stress and toxins,
electromagnetic fields disturbances; excessive cell phone usage and electronic
devices. Brain is a complicated and delicate organ that has neuron cells that
needs extra protection through special nutrition. Brain aging results from
diminished brain cell metabolism and reduced brain circulation. Many middle
aged people already feels that their memory has deteriorated beyond their age
and more cases of Alzheimer diseases and dementia happening now than ever. More
people cannot remember things, studies, events and names than they used to be
can be a sign that their memory and brain function are deteriorating.
The human
brain is one of the most sophisticated organs nature has ever made. One of the
most interesting aspects of the brain is its power to retain information, which
we call as memory. Memory is perhaps the most vital of the aspects that
differentiates human beings from other animals. However, memory can become
faulty due to several reasons, and in that case the person is not able to make
full use of his or her potentials.
Memory
is the ability of an individual to record sensory stimuli, events, information,
etc., retain them over short or long periods of time and recall the same at a
later date when needed. Poor Memory, lower retention and slow recall and are
common problems in today’s stressful and competitive world. Age, stress,
emotions are conditions that may led to memory loss, amnesia, anxiety, high
blood pressure, dementia, to more ominous threat like schizophrenia and
Alzheimer’s diseases.
The "Memory / Brain Enhancer" is designed to help memory and brain
function by giving special nutritional and herbal supplements to help protect
the brain cells and brain circulation. It can also be used on stroke patients
to protect them from memory loss and brain damage.The nature provides
a new opportunity to regain one’s full mental capacity. A number of herbs
traditionally employed in the Indian System of Medicine “Ayurveda”,
have yielded positive results.
Nootropics, which
are popularly referred to as “smart drugs”, “smart nutrients”, “Cognitive
enhancers” and “brain enhancers”, are a class of drugs that improve impaired
human cognitive abilities. Typically, nootropics are
alleged to work by altering the availability of the brain’s supply of neurochemicals (neutransmitters,
enzymes and hormones), by improving the brain’s oxygen supply, or by
stimulating nerve growth.
Since ages,
drugs and natural remedies have been prescribed to enhance memories in people. Ayurveda has a treasure-chest of such
memory enhancing
drugs, which are today popular all over the world due to their proven effective
qualities.
Omega 3 Fatty
Acids such as those found
in fish oil are also important for brain health. More specifically, low levels
of omega 3s have been associated with impaired brain function. The best source
of omega-3 fatty acids are found in fish oil.Nutrition
can make a big difference in maintaining a well oiled brain The omega-3 fatty
acids found in fish increase the brain's ability to send and receive messages
reports a scientist from Tufts University. The best way to reach the suggested
serving of omega 3( 1.1 to 1.4 grams daily for women and 1.6 grams for men) is
by eating fatty fish like Salmon, mackerel or tuna at least three times per
week.
Hawthorn:
Hawthorn in combination with Gingko biloba
improves head circulation, which in turn improves memory.
Ginkgo biloba
(Ginkgo) is popular in
Europe as a treatment of the symptoms of early stage AD and vascular dementias
(condition of diminished cognition caused by strokes). Meta-analyses and
systematic reviews indicate that ginkgo may improve cognition and function in
patients with AD. One study concluded that ginkgo might delay the progression
of AD by nine months compared to placebo. However, a well-designed study of
patients with age-associated memory impairment or very mild dementia failed to
show a benefit of ginkgo. There are several large studies in progress that
should be more definitive. Nearly all of the clinical studies use a
concentrated ginkgo extract standardized to contain 24% ginkgo flavonoid glycosides, 6% terpene
lactones, and no more than 5ppm ginkgolic acids. A
typical dose was 120-240 mg/day, in divided doses. Ginkgo may be
contraindicated in patients with bleeding disorders1,2. The extract
of the Ginkgo leaves contains flavonoid glycosides
and ginkgolides and is being used as a memory
enhancer as it has positive effects on the vascular system, especially in the
cerebellum. It works by increasing the flow of blood to the brain and to all
the blood vessels that supply blood and oxygen to the body organs. Ginkgo helps
in increasing metabolism efficiency, regulates neurotransmitters, and boosts
oxygen levels in the brain which uses 20% of the body’s oxygen. Thus it helps
in enhancing your memory, helps in treating problems like Alzheimer’s and other
symptoms of cerebral insufficiency. Cerebral insufficiency include various
problems like confusion, depression, anxiety, difficulties of concentration and
memory, absentmindedness, lack of energy, dizziness, tinnitus, and headache. It
is also said to provide energy to the body and helps to counteract the effects
of aging.It enhances mental efficiency in elderly
patients with mild to moderate memory impairment. It is also shown to improve
cognitive function in patients with dementia, to enhance blood flow to the
brain, enhances cognitive performance in patients with Alzheimer's disease.
Further it is said to enhance memory in young individuals.Many
plants in nature have antioxidant properties to protect themselves from the
harshness of nature. One such plant is ginkgo biloba.
Ginkgo has the properties to protect our brain, blood vessels, and the
circulatory system in general.
In young people, ginkgo has shown to help brain
function by increasing the blood flow in the brain by nourishing the brain
cells. It usually is very effective immediately after taking it. Students who
take ginkgo just before going for an examination also have reported, according
to studies, to have better recall ability.
It is reported to improve brain function, memory
retention, and mental clarity while increasing blood flow and oxygen supply. It
can help reduces the deterioration of nerves; neutralize free radicals that
damage the body's cells health accelerating aging. Neurological evidence also
suggests that ginkgo aids our neurotransmitter receptor sites (Including those
all-important serotonin and dopamine sites) in maintaining their youthful
resilience and firing capacity.
Ginkgo works by improving the blood
circulation to the central nervous system. This is the primary requisite for a
healthy and capable brain. Apart from this, ginkgo corrects any damage done to
the cells of different parts of the body, including the brain. It also
minimizes the effects of the blood clotting. All these properties of the ginkgo
have been studied in detail by western experts and they have obtained very
encouraging results.
The first significant effect of ginkgo biloba is the relaxation and the expansion of the blood
vessels. When this happens, the brain, as well as all the other organs,
receives more oxygen. Besides the improvement of blood circulation, the fight
against the free radicals is also a way to prevent stroke, which is one of the
main causes of memory loss.
Turmeric A majority of the evidence supporting the
use of turmeric for the treatment of
AD symptoms comes from animal studies. There are no clinical studies on
turmeric's' benefit for patients with AD. However, epidemiologic studies show a
4.4-fold lower incidence of AD in places such as India where turmeric is
commonly part of the diet. A typical dose of tincture is 5 mL,
3times/day1,2. Curcumin which is a spice
known for its anti-inflammatory effects helps a lot in preventing memory loss. Curcumin is basically that spice which gives yellow curry
its bright color and is frequently used as natural food dye.
Lemon balm leaves have historically been used as an anxiolytic and a support for memory. Two randomized,
placebo-controlled, double-blind studies indicate that lemon balm may be of
benefit for AD. In the studies lemon balm improved attention, cognitive
function, and produced calmness. Lower doses appear to be more effective for
AD. The typical adult dose is fresh-herb tincture 2-5 mL,
3 times/day1, 2.
Salvia miltiorrhiza,(Sage
)leaves are traditionally used to support memory. Spanish sage is naturally
very low in thujone, a potentially toxic compound.
Many studies evaluate Spanish sage in patients with AD because of the low thujone content. Since the herb will be used long-term to
treat AD, a species with low thujone content is
necessary. There are several small clinical trials in patients with mildto-moderate AD, which show a positive effect on
cognitive function. A typical dose is 3-5 mL, 3 times
per day. Sage may worsen gastroesophageal reflux in
some people and should be used with caution in people with seizure disorders1,2.
Sage is a mild tonic that fortifies a generally
debilitated nervous system. Instead of sedating the nervous system as some nervine herbs do, it actually stimulates the central
nervous system, strengthening it to reduce excess nervous energy. This mild
tonic quiets the nerves, relieves spasms, helps induce Sleep and combats
depression, mental exhaustion, trembling and nervousness. It has been used to
calm seasickness, and traditional herbalists even thought it useful in treating
certain forms of insanity.
It is an outstanding memory enhancer. In
this placebo-controlled, double-blind, crossover study, two trials were
conducted using a total of 45 young adult volunteers. Participants were given
either placebo or a standardized essential oil extract of sage in doses ranging
from 50 to 150 microls. Cognitive tests were then
conducted 1, 2, 4, 5, and 6 hours afterwards. In both trials, even the 50 microl dose of sage significantly improved subjects'
immediate recall.
In other research presented at the British
Pharmaceutical Conference in Harrogate (September 15-17, 2003), Professor Peter
Houghton from King's College provided data showing that the dried root of Salvia
miltiorrhiza, also known as Danshen
or Chinese sage, contains active compounds similar to those developed into
modern drugs used to treat Alzheimer's Disease. Sage has been used in the
treatment of cerebrovascular disease for over one
thousand years. Four compounds isolated from an extract from the root of
Chinese sage were found to be acetylcholinesterase (AChE) inhibitors. The memory loss characteristic of
Alzheimer's disease is accompanied by an increase of AChE
activity that leads to its depletion from both cholinergic and noncholinergic neurons of the brain. Amyloid
beta-protein (A beta), the major component of amyloid
plaques which form in the brain in Alzheimer's disease, acts on the expression
of AChE, and AChE activity
is increased around amyloid plaques. By inhibiting
this increase in AChE activity, sage provides a
useful therapeutic option to the use of pharmaceutical AChE
inhibitors. (October 24, 2003)
Rosemary is used historically as a memory enhancer,
but research on it is lacking. A typical adult dose of fresh-herb tincture used
alone is 3-5 mL, 3 times/day1, 2. Rosemary
is among the herbs for memory loss, too. Mainly, it is used as a condiment in
the Mediterranean area. However, many studies have revealed that it can enhance
the memory by improving directly the mental processes. The herbs for memory
loss are also effective in the treatment of Alzheimer’s diseases and dementia.
Memory loss is in many cases a symptom of these two health problems.The
active ingredient in rosemary, known as carnosic acid
(CA), can protect the brain from stroke and neurodegeneration
that is due to injurious chemical free radicals. These radicals are thought to
contribute not only to stroke and neurodegenerative conditions such as
Alzheimer’s, but also to the ill effects of normal aging on the brain.
Withania somnifera Withania somnifera
(Ashwagandha) has been used for thousands of years as
a popular remedy for many conditions. Withania somnifera is one of the best known and most researched Ayurvedic herbs and holds a place in the Ayurvedic traditions similar to Ginseng in Chinese
therapies. For that reason, Withania somnifera has been often referred to as the “Indian
Ginseng”. Withania somnifera
is used in several indigenous drug preparations for maintaining health as well
as treatment of several disease conditions.
Ashwagandha is an adaptogen—an
agent that nonspecifically strengthens both the body and mind. Historically adaptogens have been used to offset the symptoms of aging.
In vitro, ashwagandha stimulated neurite
outgrowth in human brain cells, which may help damaged neuronal circuits in the
demented brain. Human trials are lacking. Ashwagandha
has a calming effect and is indicated for people with AD plus agitation. For
patients that are more catatonic (immobile), a different adaptogen
may be better suited1,2.
Withania somnifera
extract (50, 100 and 200 mg/kg; orally) improved retention of a passive
avoidance task in a step-down paradigm in mice. It also reversed the
scopolamine-induced disruption of acquisition and retention and attenuated the
amnesia produced by acute treatment with electro convulsive shock (ECS),
immediately after training. Chronic treatment with ECS, for 6 successive days
at 24 h intervals, disrupted memory consolidation on day 7. Daily
administration of ashwagandha for 6 days
significantly improved memory consolidation in mice receiving chronic ECS
treatment. Withania somnifera
(50 mg/kg) significantly reversed both ibotenic
acid-induced cognitive deficit and the reduction in cholinergic markers after 2
weeks of treatment.
In another study conducted, it was observed
that Withania somnifera
extracts induced an increase in cortical muscarinic
acetylcholine receptor capacity which might partly explain the
cognition-enhancing and memory-improving effects of the extracts as observed in
animals and humans.
Ashwagandha is one of the most essential components used in
enhancing memory and overall brain functioning. Ashwagandha
is an adaptogen, stress-buster and a re-vitalizer. Ashwagandha has a
cooling and calming effect on the brain. After a hard day’s work, ashwagandha can bring the brain back to its normal state of
functioning.
Ayurveda regards ashwagandha
as a medha rasayana, i.e. a
brain tonic. It has direct results in improving the memory capacity of the
brain. Ashwagandha is very powerful in making new
concepts seem clearer and easy to understand. It is a vital component of almost
all herbal brain tonics available in the market.
Concentrated extract of Brahmi
contains the active molecules Bacoside A andB. Bacoside A assists in the
release of Nitric oxide, that causes the relaxation of the aorta and veins and
allows blood to flow more smoothly though the body. Bacoside
B is a protein that nourishes the brain cells. Triterpenoid
saponins and Bacosides of Bacopa monnieri play key role for
enhancing nerve impulse transmission. Herasaponin
present in Bacopa exhibits calming sedative action
and thus reduce sleeplessness.
Biochemically, nervous-system effects of Brahmi have been attributed to an enhancement of the
effects of the neurotransmitters acetylcholine and possibly serotonin or GABA
(Gamma Amino Butyric Acid).
It can help cognition and memory by
enhancing memory and learning, improving concentration and mental clarity,
enhancing mental cognition in older adults. In addition, it repairs nerve
damage, as well as stroke and brain injury.
Hippocampus is involved in the formation and retrieval of memories. Age or
disease damages synapses, disrupting neurotransmitters. As a result, new memory
creation is impaired and memory loss occurs. Bacosides
repair damaged neurons by boosting kinase, which is
the protein used to synthesise new neurons. It
improves the synaptic activity and thus memory can be restored.
Brain-boosting powers are claimed for antioxidants. Although oxygen is vital to
our bodies, too much or too little, creates a reaction which eventuates in
toxic by-products called free radicals. Every cll in
the body is at risk from damage by these highly reactive free radicals and
brain cells are no exception. Because the "mop up" free radicals,
antioxidants have a protective effect on neurons and may also therefore, be a
useful weapon in the fight against cognitive dysfunction - and may prevent
neurological damage down the road3.
Preclinical studies have
reported that the administration of extract (40mg/kg, p.o.)
for three or more days is reported to improve the performance of rats in
various learning situations.
Studies
revealed that bacosides which are the major phytoconstituents in Bacopa monnieri, help to repair damaged neurons by enhancing
proteins involved in the regeneration of neural-cell synapses. These are the
relay stations of the brain that facilitate the transmission of nerve impulses.
Thus Bacopa monnieri can be
viewed as a neural nourisher, restoring depleted
synaptic activity and leading to enhanced memory function.
Baccopa monneri is a
well-known nootropic plant having
sedative,tranquilising4 ,memory-enhancing 5-7 antioxidant
8 and hepatoprotective effects 9,10
Vinpocetine has been found to help restore long-term potentiation (LTP) when given after its disruption; LTP is
the memory quality that is associated with prolonged and profound learning and
memory11. Researchers generated a lesion in the area of rats'
brains found to be responsible for LTP. What resulted was a significant
decrease in LTP's signals, indicating that memory formation had been halted.
But after the rats received vinpocetine for six days,
LTP was induced and found to be completely restorable. In this study too, vinpocetine was tested against Hydergine®, a legendary cognitive enhancer, and
found to be equally effective. Hydergine increases
the release of brain-derived neurotrophic factor
(BDNF) in the hippocampus, activating both glutamatergic
synaptic transmission and, in turn, NR2B-containing NMDA receptors12.
Its dramatic enhancement of conceptual ability may be an example of Hebb's rule. Could vinpocetine do
the same?
Vinpocetine is a powerful brain and memory enhancer
that may yet eclipse all other smart drugs. Vinpocetine
improves blood flow to the brain, makes it easier for the brain to use glucose
and oxygen, and allows the brain to survive longer and better after periods of
oxygen deprivation. Vinpocetine,
powerful brain de-ager, referred to as “Viagra for the Brain,” is increasing
worldwide in the treatment of cognitive deficits related to “normal” aging.
Formerly available as pricey European smart drug Cavinton
(AKA VinpocetineRX; Periwinkle; myrtle Vincapervinc; cezayirmenek-sesi),
the natural substance has recently become available as a low-cost nutritional
supplement in the US.
Vinpocetine takes aim at the brain much the same way
Viagra targets the genitals. The mechanism in both improves blood flow,
inhibiting a phosphodiesterase enzyme that degrades
cyclic GMP to relax constricted arteries and smooth muscle. With Vinpoc-etine, cerebral microcirculation and metabolism
improve and brain ATP (the cellular energy molecule) production increases along
with the utilization of glucose (cellular energy food) and oxygen.
N-acetyl-L-carnitine- This neuroprotective
compound is known as a "short-term memory enhancer" and is vital for
production of the neurotransmitter acetylcholine, required for mental function.
It may help protect neurons from oxidative damage and prevent age-related
decline in memory and mental function. In studies, it has been shown to slow
the progression of neurodegenerative disorders such as dementia and Alzheimer's
disease.This antioxidant has displayed benefits for
the brain and neurological function. It may defend against various toxins,
break down mucus. ALC has a significantly more noticeable effect on the mind
than carnitine. ALC usually enhances mental clarity
and focus, along with slight mood elevation. The effects of carnitine
are more physicial than mental, in the sense that carnitine may provide physical energy whereas acetyl-L-carnitine provides more mental energy.
Centellaasiatica(GotuKola)
Centella asiatica, commonly known as Mandookaparni is a widely available Indian herb has been
used for centuries in Indian systems of medicine. In India for the last 3,000
years of Ayurvedic medicine, it has been used for the
purposes like boosting memory, wound healing, a mild diuretic, increasing
concentration, alertness, as well as anti-anxiety and anti-stress. It has also
been used for centuries in the treatment of liver and kidney problems.
Gotu kola has been referred to as "food for the
brain". This herb has demonstrated anti-anxiety and anti-stress effects,
as well as improving mental functions such as concentration and memory. It has
a calming effect on the body and is chiefly used to support the central nervous
system. These beneficial qualities make Gotu kola an
excellent herb for children with A.D.D. because it has a stimulating effect on
the brain that increases one's ability to focus while having a soothing and
relaxing effect on an overactive nervous system. it has been used for many
other symptoms too. Gotu Kola also has anti-oxidant
properties, and its aphrodisiac properties have given it the ancient reputation
of giving men erections with the strength and agility. Centella
Asiatica is used to re-vitalize the brain and nervous
system, increase attention span and concentration and combat ageing.
The gotu kola is very effective in increasing the
circulation of blood to different parts of the body, including the brain. It
protects the brain from damage due to the wear and tear of its cells. Gotu kola can regenerate lost energy from the human system,
and make the person feel more zestful.
Gotu kola is generally used in tonics intended to
re-vitalize the brain. It improves concentration, makes the brain more
receptive to information and also brings about an enhancement in the memory.
In
pharmacological and clinical trials Centella asiatica has been found to improve the power of
concentration and general ability and behavior of mentally retarded children.
The clinical trials demonstrated that the extract increases the intelligence
quotient in mentally retarded children. In a clinical trial an Ayurvedic drug having Centella asiatica as one of the main ingredients reported marked
improvement is seen in children with behavioral problems. It is found to
improve short-term memory and learning performance due to its possible nootropic action involving cholinergic and GABAergic modulation.
Preclinical studies showed an impressive
improvement in memory. The treated rats retained learned behavior 3 to 60 times
better than the untreated rats. Centella asiatica causes an overall decrease in the turnover of
central monoamines, implicating the involvement of Norepinephrine,
Dopamine and 5-HT systems in learning and memory process.
Citicoline: It is a form of choline
that helps replenish the brain with phosphatidylserine,
a key cell membrane phospholipid. The compound also
appears to have a number of effects that protect neurons in the brain from
degeneration. Citicoline
(cytidine-5-diphosphocholine, or CDP-choline) may
help boost the levels of certain key brain phospholipids and has led the
researchers to suggest that the administration of oral citicoline
may be of use in reversing age-related changes in the brain and help people
after stroke to prevent memory loss.
Phosphatidyl
Serine (PS): It is the
brains major phospholipid, PS is essential to cell
membrane, and may protect against age-related deterioration. This nutrient may
also be effective at helping to improve memory and neural function. PS is a phospholipid that is a component of brain cell membranes,
and is present in every single cell in the body. Taken as a dietary supplement,
PS is a key building block for nerve cells, which are the basis for effective
brain function on every level. It can help reverses memory loss linked to aging;
helping the brain respond to stress; improving mood, fighting depression.
DMAE: It has been demonstrated to elevate mood,
increase intelligence, improve memory and learning as it extends lifespan. It
also been shown to stabilize lysosome membranes,
preventing the uncontrolled leakage of lysosomal
enzymes in the cells and the resulting damage of important intracellular
organelles. Normally found in small amounts in our brains, supplemental DMAE
converts into the vital neurotransmitter acetylcholine. DMAE is a precursor to choline and acetylcholine. However, DMAE has been shown to
cross the blood-brain barrier faster than choline. It
is the choline inside cells that is converted to phosphatidylcholine, used in the building and repair of
cell membranes, especially in the brain.DMAE is a
memory enhancing substance common to a number of drugs that are known to
stabilize cell membranes. Cell membrane degradation has been proposed as one of
the prime mechanisms of aging. DMAE is a precursor to choline
and acetylcholine. However, DMAE has been shown to cross the blood-brain
barrier faster than choline. It is the choline inside cells that is converted to phosphatidylcholine, used in the building and repair of
cell membranes, especially in the brain.DMAE is found
in fish, especially sardines and anchovies. Research suggests that DMAE may
increase levels of the neurotransmitter acetylcholine, one of the chemicals in
the brain that is essential for memory and learning and enhances mental powers.
Although evidence that DMAE actually influences acetylcholine levels is
contradictory, some people who have tried DMAE report better memory powers,
especially improved short-term memory. In addition, improved concentration,
mental clarity, focus, and sleep were reported as well. Often times,
nutrition-oriented physicians prescribe DMAE along with the dietary supplement phosphatidyl choline, another
memory enhancer.
B
vitamins are important for
protecting your brain. The ability to process complex tasks in the brain has
been attributed to folate( one of the B vitamins). B
vitamins seem to play a role in the functioning of neurotransmitters. Fruits
and vegetables, especially leafy green vegetables like spinach are rich sources
of folate. Also important for cognitive function: B12
found in meat, fish and fortified cereals. Many people become deficient in B12
as they age, and low levels of the vitamin have been linked to problems with
verbal memory, visual recall and short-term memory.If
you are on acid blockers long term ask your doctor to check your vitamin B12
levels, since these types of medications can sometimes interfere with the
absorption of B12.Vitamin B6 plays an essential role in brain function because
it controls the synthesis and production of neurotransmitters like serotonin
and GABA. It is responsible for controlling sleep patterns, moods, appetite and
pain sensitivity and has been found to alleviate depression, anxiety and stress
disorders. Deficiencies can cause insomnia and central nervous system
malfunctioning. Supplementation can improve memory loss and other ailments.Vitamin E is a powerful antioxidant that helps to
protect brain cells and the myelin sheath against the damage caused by free
radicals. Food sources include wheat germ, nuts like walnuts, seeds, eggs,
leafy green vegetables, and whole grains. It has been shown to slow the
progression of Alzheimer's disease.
Huperzine A:Huperzine A is an alkaloid that acts as an acetylcholinesterase inhibitor, inhibiting the enzyme that
breaks down the neurotransmitter, acetylcholine. Derived from Huperzia Serrata, a herb used for
centuries in traditional Chinese medicine, it has antioxidant and neuroprotective properties. It has proven to be effective
in improving cognitive and memory abilities in those with Alzheimer's disease.
Mulethi (Glycyrrhiza glabra) Mulethi is none other than licorice, the herb already known worldwide for its
various curative properties. Mulethi is an efficient
brain tonic and a re-vitalizer for the brain. Like
most of the other herbs mentioned here, mulethi also
rejuvenates the brain. In times of stress, mulethi
can stimulate mental functions so as to feel a calming and relaxing effect. Mulethi increases the circulation into the central nervous
system and balances the sugar levels in the blood. Mulethi
is frequently provided to students who are preparing for important
examinations, as it helps to remember small facts and bits of information.
Acorus calamus:It is traditionally employed in nervous
disorders. The rhizomes of Acorus calamus
are used in loss of memory given in combination with other drugs like Centella asiatica, Bacopa moneira and Rauwolfia serpentina as a memory booster.Acorus calamus well known
for its memory enhancing activity enhanced learning performance, of the
descendents of drug-administered animals, and the animals themselves. Acorus when mixed with food and given to albino rats,
showed excellent learning performance, enhancing activity proving its popular
memory boosting activity. It is a very vigorous brain tonic, because
it shows results in a very short time. It increases the overall memory of the
person and strengthens the nervous system. It is prescribed to people who have amnesia.Improving the memory is a quest on which human
beings have embarked centuries ago. In almost all civilizations, there have
been attempts to discover the best herbs for brain enhancement with minimum
side-effects. Perhaps, Ayurveda wins the race in
this. All the herbs Ayurveda uses for its brain
tonics have minimum side-effects and are quite safe for the human beings.
Western science is now warming up to these herbs and is looking upon them as
effective supplements for the human brain.
Coleusforskohli :Forskolin
is a diterpene from the roots of the Indian plant
Coleus forskohli which directly activates the adenylate cyclase and raises
cyclic AMP levels in a variety of tissues. Cyclic AMP is an important
cell regulating compound. Once formed it activates many other enzymes involved
in diverse cellular functions. Under normal situations cAMP
is formed when a stimulatory hormone (e.g., epinephrine) binds to a receptor
site on the cell membrane and stimulates the activation of adenylate
cyclase. This enzyme is incorporated into all
cellular membranes and only the specificity of the receptor determines which hormone
will activate it in a particular cell. Forskolin
appears to bypass this need for direct hormonal activation of adenylate cyclase. As a result of
this direct activation of adenylate cyclase, intracellular cAMP
levels rise. The physiological and biochemical effects of a raised
intracellular cAMP level include: inhibition of
platelet activation; inhibition of mast cell degranulation
and histamine release; increased force of contraction of heart muscle;
relaxation of the arteries and other smooth muscles; increased insulin
secretion; and increased thyroid function.
Guarana Seed Powder (Paullinia cupana) Guaranine is probably just caffeine bound to a tannin
or phenol. In living plants, xanthines (such as
caffeine) are bound to sugars, phenols, and tannins, and are set free or
unbound during the roasting process. Guaraná seeds
contain up to 4-8% caffeine (25,000 to 75,000 ppm),
as well as trace amounts of theophylline (500 to 750 ppm) and theobromine (300 to 500 ppm). They also contain large quantities of alkaloids, terpenes, tannins, flavonoids,
starch, saponins, and resinous substances.The
xanthine alkaloids (caffeine, theophylline,
theobromine) are believed to contribute significantly
to guaraná's therapeutic activity. In clinical
studies, theophylline stimulates the heart and
central nervous system, enhances alertness and alleviates fatigue. It also has
strong diuretic activity and reduces constriction of the bronchials,
making it useful in asthma. Theobromine has similar
effects. Certainly many traditional uses of guaraná
may be explained by its caffeine content. Among its many documented effects,
caffeine has been shown to facilitate fat loss and reduce fatigue.The
main chemicals found in guaraná are: adenine, allantoin, alpha-copaene, anethole, caffeine, carvacrol, caryophyllene, catechins, catechutannic acid, choline, dimethylbenzene, dimethylpropylphenol,
estragole, glucose, guanine, hypoxanthine, limonene,
mucilage, nicotinic acid, proanthocyanidins, protein,
resin, salicylic acid, starch, sucrose, tannic acid, tannins, theobromine, theophylline, timbonine, and xanthine.The use
of guaraná as an effective energy tonic, for mental
acuity, and to enhance long-term memory recently was validated by scientists.
In a 1997 in vivo study, guaraná increased physical
activity of rats, increased physical endurance under stress, and increased
memory with single doses as well as with chronic doses. Interestingly, the
study revealed that a whole-seed extract performed more effectively than did a
comparable dosage of caffeine or ginseng extract. Another Brazilian research
group has been studying guaraná 's apparent effect of
increasing memory, thought to be linked to essential oils found in the seed.
The plant also was found to enhance memory retention and to have an anti-amnesic
activity in mice and rats. A U.S. patent has been filed on a combination of
plants (including guaraná) for promoting sustained
energy and mental alertness "without nervousness or tension." Guaraná (often in combination with other plants) also has
been found to facilitate weight loss, by creating a feeling of fullness and
having a mild thermogenic effect.
Evolvulus alsinoids
has been used traditionally as a brain tonic and sedative15
,anthelmintic,
antiepileptic and against leucoderma16,3.
Cow’s ghee (clarified butter fat) is described in Ayurveda as a memory enhancer, anticonvulsant and antiinflammatory agent17,3.Cow ghee improves
grasping, storing and recall, the three aspects of brain. It also stimulates
appetite, improves quality of life, physical endurance, vigour
and eyesight. Nose is the gateway of brain and any product introduced through
the nostril has immediate access to the brain tissue. Even modern medicine has
identified the potential of this path which bypasses the blood brain barrier
and without much efforts, the valuable drug can be made bio-available in plasma
and CSF in just 1.5 minutes.Cow ghee is one of the
best vehicles for brain functions and the herbs processed within this ghee
fortify the clinical effects further. They help to improve the
micro-circulation and deliver oxygenated blood to the brain tissue. The nasal
passage has connection with the brain, eyes, throat, ears and helps to restore
the physiological function of these organs. It is scientifically confirmed that
nasal medication has following benefits: Nasal drops especially help to treat
all kinds of ailments in supra-clavicular region.Nose is the getway of
cranium, hence it spreads the effect in the brain area. In addition, it also
helps to improve the oxygenated blood supply and enhance the microcirculation
through the sinuses. The herbal ingredients in the nasal drops have the ability

better.
Cebtakka Asiatica(Mandukparni )Whole plant is a nervine
tonic and memory enhancer.
Celastrus paniculata Celastrus paniculata
belonging to the genus of woody, climbing shrubs is distributed almost all over
the India. In folk medicine the seeds are boiled and taken for blood
purification. The seeds constitute the drug; they are bitter, and have an
unpleasant odour and are traditionally used for
sharpening the memory. Recent preclinical studies of the seed extract on male
rats showed an improvement in learning and memory in both the shuttle-box and
step-through paradigms. The study also demonstrates that the
cognitive-enhancing properties of extract of Celastrus
paniculatus seed could be attributed to its
antioxidant effect. Yet another study investigated the effects of the seed oil
of Celastrus paniculatus on
the 6 day performance of young adult rats in a navigational memory task-the
Morris water maze. These studies confirm the memory boosting properties of Acorus calamus.
Green
tea is also one of the
herbs for memory loss that contain antioxidants. In fact, most of the herbs for
memory loss contain substances that help the body to fight the free radicals.
Another important effect that may be observed is to enhance of the energy

Tibetan
Rhodiola is in many ways more powerful than Ginseng. It is a superb herb for
people who work very hard, either physically or mentally. Tibetan Rhodiola has been shown to improve endurance and mental
capacity, including memory enhancement. It has been shown to be a superb tonic
and energizer for those into physical fitness, and a superior tonic for those
stuck behind a desk or at a computer terminal for long periods of time. Consumption
of a small amount of Rhodiola extract significantly
improves a person’s capacity to absorb and utilize oxygen. Tibetan Rhodiola is
especially beneficial to those who live under stressful conditions. It has been
proven that Tibetan Rhodiola reduces the body’s
stress reactions, and thus relieves mental stress as well. People stay focused
and suffer far less from fatigue even under severe stress. It is the ideal
herbal supplement for the modern world.Rhodiola rosea is a popular plant in traditional medical systems in
Eastern Europe and Asia with reputation for stimulating the nervous system,
decreasing depression, enhancing work performance, eliminating fatigue, and
preventing high altitude sickness. Rhodiola rosea has been categorized as an adaptogen
by Russian researchers due to its observed ability to increase resistance to a
variety of chemical, biological, and physical stressors. It helps improve
alertness and mood, better motivation, and overall sense of well-being.

The risk for
developing dementia is lower in people with a diet rich in flavonoids. Therefore a diet
rich in a variety of fruits and vegetables is an important part of AD
treatment. Blueberries are on the top of the list of foods that contain
constituents that enhance neuronal function. Beets are high in betaine, which helps lower homocysteine
levels. Homocysteine may be the link between
hypertension and dementia. Reference:
The authors
recommend the following regimen for addressing AD: (1) Ginkgo leaf extract
containing 24% ginkgo flavonoid glycosides, 6% terpene lactones, and no more that 5 ppm
ginkgolic acids, 120-240 mg/day, in divided doses;
(2) 10 mL of the formula with the following
components in divided doses, 3 times/day: 30% turmeric tincture of fresh
rhizome, 15% sage tincture of fresh leaf, 15% lemon balm tincture of fresh
herb, 10% rosemary tincture of fresh herb, and 30% ashwagandha
tincture of fresh root; (3) 400 IU vitamin E and 1000 mg vitamin C taken
together, may be divided doses; (4) blueberries 1 cup/day as berries or juice;
(5) beets ½ cup daily or every other day; and (6) regular physical and mental
exercise.
The treatment
plan described in this study is one example of how antioxidant herbs, adaptogens, diet, and exercise may be used in attempt to
treat the symptoms of AD.
