Bacopa Benefits

Some studies indicate that bacopa monnieri may help preserve memory and enhance cognitive function. Compounds responsible for the medical effects of bacopa monnieri include saponins, alkaloids and sterols. Another constituents have since been identified, including betulic acid, stigmasterol, beta-sitosterol, as well as numerous bacosides and bacopa saponins. The triterpenoid saponins and their bacosides are responsible for bacopa capability to enhance nerve impulse transmission. Bacosides have antioxidant effects, enhance nerve impulse transmission and have the ability to repair damaged nerve cells. Bacosides help the repair of damaged neurons by enhancing kinase activity, neuronal synthesis, restoration and regeneration of synaptic activity resulting in nerve impulse transmission.

Cognitive Function

A 2002 study reported in the journal Neuropsychopharmacology found that using bacopa for 3 months significantly improved memory. Participants were tested on retention of new information, and the placebo group forgot the information more quickly than the group taking bacopa. One particularly study on bacopa monnieri was performed in Australia, using neuropsychological testing. These tests measure a number of different cognitive skills, such as attention, memory consolidation, short-term memory,  decision making, problem solving, information processing, and verbal learning. In one group were given 300 milligrams of bacopa daily, and the others received a placebo. The tests were repeated 5 and 12 weeks after the study began. The researchers noticed an important improvement among the people in the bacopa group compared to those in the placebo group. The findings demonstrated that bacopa significantly developed performance on specific tests, most notably those dealing with information processing, verbal learning and memory consolidation.

Anxiety

Studies in humans have found that bacopa monnieri may help to reduce stress and anxiety. In a double-blind placebo controlled study at Helfgott Research Institute, 48 participants, 65 or older, were given a daily dose of 300 mg of bacopa or a placebo for 12 weeks. Those who took the bacopa showed improved word recall memory scores in comparison to the placebo group. The Bacopa group also showed less anxiety and depression after taking the supplement when compared to the placebo group. This study provides further evidence that bacopa monnieri has property for safely enhancing cognitive performance in the elderly. Bacopa boosts the effects of certain neurotransmitters, including acetylcholine and serotonin. This effect on neurotransmitters is what enables to decrease anxiety and depression symptoms.

Epileptic Seizures

Some studies suggest that bacopa could reduce the frequency and duration of epileptic seizures by regulating the activities of the GABA (gamma-aminobutyric acid) receptors. GABA controls important functions of the central nervous system. A study on thirteen epilepsy patients using a defatted, ethanolic extract of bacopa  was performed over a 5-month period. The participants showed improvement in the frequency of seizures over a period of 2 to 5 months. The seizures ceased in 5 cases.

Antioxidant Activity

Bacopa seem to have important antioxidant activity in the brain, which may protect brain cells from damage caused by free radicals, waste substances that can have toxic effects on cells. A study at the University of Catania, found that Bacopa’s antioxidants have a protective property on human DNA fibroblasts, suggesting that this herb may be helpful in the treatment of diseases in which free radicals play a key role.

Bacopa Dosage

Bacopa monnieri extract is available in powders, capsules, syrups and teas. The dose for bacopa monnieri is generally 200-400 mg per day in 2 or 3 divided doses of an extract standardized to 20 percent bacosides.
