Since the time of Vedas, Brahmi,
a perennial creeping plant (Bacopa
monnieri) has been in use as a nerve
tonic for rejuvenating mental health and
for enhancing memory. This plant, found
extensively in wet, marshy and damp areas,
has been mentioned by ancient sages, medical
men in almost all social, medical and
religious treatises. Ayurveda, the ancient
science of life has more than one reference
of the plant for the enhancement of memory
and mental agility of mankind. The famous
Charaka Samhita written in the 1st century
refers this plant for curing mental retardation
leading to psychosis. Pharmacological
properties of this plant have been clearly
mentioned as having properties of cognitive
enhancement and anxiolytic effect. The
other treatise Sushruta Samhita makes
this more explicit and describes Brahmi
to be effective in memory loss.
Initially, CDRI's interests in Brahmi
were prompted by its effect on learning
and memory described in ancient Ayurvedic
treatises. The early systematic studies
carried out at the institute were very
encouraging and therefore, it was taken
up for detailed investigation of active
plant component and pharmacological and
other studies. Subsequently, it was decided
to develop the plant as a herbal remedy.
As a result, a quality herbal preparation
has been developed from B. monnieri
which has been standardised in terms of
its bacosides contents.
During efficacy and safety studies in
rodent and non-rodent models, the Brahmi
extract was found safe and efficacious.
Preclinical neuropharmacological studies
demonstrate that both the standardised
extract and bacosides improve short-term
and intermediate memories, thus , improving
the long-term memory. The bacosides also
significantly enhance protein synthesis
in those regions of the brain which are
implicated in the memory formation, a
possible explanation for its memory improving
effect.
Double blind cross over clinical studies
have been carried out in children, elderly
persons and normal healthy volunteers.
Studies carried out in normal healthy
volunteers, elderly subjects with age
associated memory impairment and children
with attention deficit hyperactivity disorder
(ADHD) have shown that the drug is safe,
well tolerated, efficacious and devoid
of any side effects. Study on children
with ADHD has shown that the preparation
, after 12 weeks of its use, significantly
improves sentence repetition, logical
memory and paired associate learning.
This standardised preparation has been
licensed to M/s
Lumen Marketing Company, Chennai,
for commercialisation. They have launched
the preparation in the market under the
brand name Memory
Sure .
