- Nootropic
- [Anxiolytic](/reference/anxiolytic/)
- Memory enhancer
- [Neuroprotective](/reference/neuroprotective/)
- [Antioxidant](/reference/antioxidant/)
- Anti-epileptic

## How does it work?

- Active compounds: Bacosides A and B (dammarane-type triterpenoid [saponins](/reference/saponins/)), betulinic acid, loliolide, asiatic acid, [quercetin](/reference/quercetinquercetin/).
- Neuronal repair: Bacoside aglycone units ([jujubogenin](/glossary/compounds-g-l/#jujubogenin)/pseudojujubogenin) repair damaged neurons, stimulate kinase activity, restore synaptic function, and improve nerve transmission.
- Acetylcholinesterase inhibition: [Quercetin](/reference/quercetinquercetin/), wogonin, [apigenin](/glossary/compounds-1-a/#apigenin), and bacopaside X dose-dependently inhibit AChE, with bacopaside X most potent.
- Antioxidant: Increases glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase; decreases malondialdehyde (MDA).
- Anti-inflammatory: Decreases IL-1beta, IL-6, and TNF-alpha; inhibits TNF-alpha and IL-6 release by activated N9 microglial cells.
- NF-kB modulation: Reduces NF-kB phosphorylation to suppress neuroinflammation.
- Alzheimer's pathology: Modulates GSK-3beta/Wnt/beta-catenin signaling and ameliorates mitochondrial dysfunction.
- Neurotrophic: Induces neurotrophic factors supporting neuronal growth and survival.

## How is it used traditionally?

## Recent safety updates

- Generally well tolerated with high therapeutic index; adverse event rates similar to placebo in clinical trials.
- Most common side effects are gastrointestinal: increased stool frequency, nausea, abdominal cramps.
- Occasional reports of dry mouth, flu-like symptoms, headache, drowsiness (uncommon).
- No serious or severe adverse effects reported in clinical trials.
- Not linked to liver enzyme elevations or clinically apparent liver injury (LiverTox database).
- Drug interactions: May increase side effects of drugs metabolized by the liver (CYP [enzymes](/glossary/compounds-d-g/#enzymes)).
- Caution with cholinergic drugs (donepezil, rivastigmine, galantamine, tacrine) due to additive acetylcholine effects.
- May increase thyroid hormone levels; avoid with thyroid hormone medications and in hyperthyroidism.
- Contraindicated in pregnancy, stomach ulcers, intestinal/urinary blockages, slow heart rate, and lung disease.

## Recommended Dosage
