Bacopa monnieri, also known as Brahmi or Waterhyssop, is a plant used in Ayurveda for its memory-enhancing properties and control of blood sugar levels. It contains active compounds such as alkaloids, saponins, and cucurbitacins, which have various biological activities. The plant has been studied for its potential in treating Alzheimer’s disease, Parkinson’s disease, attention deficit hyperactivity disorder (ADHD), and depression. Animal studies have shown promising results in reducing symptoms and protecting against neurodegeneration. Concerning safety, Bacopa monnieri has been found to be generally non-toxic, with no serious side effects reported. However, interactions with certain medications and contraindications in conditions like hyperthyroidism should be considered. Further research is needed to determine optimal dosages and ensure safety, especially for pregnant and breastfeeding women.
Antioxidants are substances that help protect against cell damage caused by potentially harmful molecules called free radicals.
Research suggests that damage caused by free radicals is linked to many chronic conditions, such as heart disease, diabetes, and certain cancers (3Trusted Source).
Bacopa monnieri contains powerful compounds that may have antioxidant effects.
For example, bacosides, the main active compounds in Bacopa monnieri, have been shown to neutralize free radicals and prevent fat molecules from reacting with free radicals (4Trusted Source).
When fat molecules react with free radicals, they undergo a process called lipid peroxidation. Lipid peroxidation is linked to several conditions, such as Alzheimer’s, Parkinson’s, and other neurodegenerative disorders (5Trusted Source, 6Trusted Source).
Bacopa monnieri may help prevent damage caused by this process.
For example, an older study showed that treating rats with dementia with Bacopa monnieri reduced free radical damage and reversed signs of memory impairment (7Trusted Source).
More studies in humans are needed to better understand the effects of Bacopa monnieri on on neurodegenerative disease, if any. A systematic review of 5 randomized controlled trials found no benefit of this herb in the treatment of Alzheimer’s, though the authors did note that the studies were of small sample sizes (8Trusted Source, 9Trusted Source).

Inflammation is your body’s natural response to help heal and fight disease.
However, chronic, low-level inflammation has been linked to many chronic conditions, including cancer, diabetes, and heart and kidney disease (10Trusted Source).
In test-tube studies, Bacopa monnieri appeared to suppress the release of pro-inflammatory cytokines, which are molecules that stimulate an inflammatory immune response (11Trusted Source).
Also, in test-tube and animal studies, it inhibited enzymes, such as cyclooxygenases, caspases, and lipoxygenases — all of which play key roles in inflammation and pain (11Trusted Source, 12Trusted Source).
What’s more, in animal studies, Bacopa monnieri had anti-inflammatory effects comparable to those of diclofenac and indomethacin — two nonsteroidal anti-inflammatory drugs commonly used to treat inflammation (12Trusted Source, 13Trusted Source).
Bacopa is thought to improve cognitive function—how you think, learn, and remember things.12 The way that bacopa improves your brain function is not fully understood.
Bacopa appears to positively affect the hormone dopamine, protecting it from being removed from the brain.3 Dopamine plays an important role in many brain functions, including motivation, reward, memory, and mood.4
Bacopa also has antioxidant effects, protecting cells from dying or becoming damaged by cellular oxidation.2

Cell death or oxidation is linked to many brain-related diseases, such as Alzheimer's disease and Parkinson's disease.
