Bacopa monnieri as a Potent Brain Tonic

1. In clinical and preclinical studies, Bacopa monnieri has been shown to contribute to enhanced exploratory behavior and greater desire to seek out novelty, sharpened memory, and increased learning and retention. A placebo-controlled, double blind study, tested the efficacy of Bacopa monnieri in children. For six weeks, 50 normal school children split into two groups were given Bacopa monnieri and placebo respectively. At the conclusion, they were evaluated for attention, concentration, and memory. Bacopa monnieri was shown to improve all these aspects significantly.

2. The use of herbal extracts to improve brain function is becoming increasingly popular and, in a study by Bhattacharya et. al, reported in Phytotherapeutic Research 14 (3), 174-9 (2000), the effects of the Ayurvedic herb Bacopa monniera (BM), also known as Bacopa monnieri, were compared with Deprenyl, and both substances were assessed as to their effect on brain chemicals associated with oxidative stress and memory function.

In the study carried out in rats, a standardised extract of Bacopa for 7, 14 or 21 days was compared with deprenyl. After 14 and 21 days of Bacopa there was an increase of Super Oxide Dismutase (SOD), Catalase (CAT) and Glutathione Peroxidase (GPX) in all brain areas, whereas deprenyl showed increased antioxidant activities only in the frontal cortex and the striatum.

The authors suggest that the antioxidant and free radical scavenging effects of Bacopa may partly explain the cognitive-facilitating action of the herb.

Bacopa monnieri as stress reliever

Bacopa monnieri induces a sense of calm and peace in its users. It is unique in its ability to invigorate mental processes whilst reducing the effects of stress and nervous anxiety. This makes Bacopa monnieri extremely applicable in highly stressful work or study environments where clarity of thought is as important as being able to work under pressure. Many people have the intelligence to perform to strict standards, but lack the composure and self-confidence to reach them. Additionally, Bacopa monnieri helps soothe the restlessness and distraction that nervousness causes. Bacopa monnieri is ideal for students and workers faced with this problem.

Bacopa monnieri increases memory

1. Bacopa monnieri has shown to be helpful in treating ADD (Attention Deficit Disorder), age-related mental deterioration and concentration difficulties due to stress, it may be incredibly beneficial where there is no health condition, but only the desire to improve cognitive function. An animal study in 1982 found that Bacopa monnieri improved the initial acquisition of learned information as well as retention ability. The study also showed that Bacopa monnieri delayed the length of time it took for the information to become extinct or 'unlearned'. Bacopa monnieri is as eminently suited to a healthy, young student looking to maximize their ability to focus and study, as to an elderly person hoping to regain their memory. It enables people to optimize their intellectual potential and mental vitality for the betterment of both personal and professional pursuits.

2. Central Drug Institute of India discovered that Bacopa monnieri contained two main active ingredients, Bacosides A and B. The neurobiological effects of these isolated molecules were found to increase protein kinase activity and new protein synthesis, specifically in cells in regions of the brain associated with long-term memory. They determined that this long-treasured herb had the amazing ability to facilitate learning, memory and concentration by stimulating neural activity.
