- Generally recognised as safe. Often a common herb with reasonable harvest and use; still read the specific warnings on the card.
- Information. Primarily informational — details in the text and warnings below matter most.
- Caution. Needs extra care (dose, duration, sensitive groups, interactions).
- Risky. Significant risks — verify sources, contraindications and professional guidance.
- Not for home experimentation. Not suitable to experiment with at home without knowledge and certainty.
- High risk for internal use. Particular risk with internal use (e.g. alkaloids); avoid prolonged or irresponsible dosing.

Identification and mix-ups
Creeping to prostrate perennial succulent herb in Plantaginaceae, about 20–30 cm, rooting at the nodes. Stems thin, fleshy, often partly submerged. Leaves opposite, small, fleshy, oblanceolate to oval-oblong, 1–2 cm, entire, waxy, non-aromatic. Flowers small, solitary, actinomorphic, white to pale purple, with 4–5 lobes.
Possible mix-ups and risks
Often confused with or loosely substituted by gotu kola (Centella asiatica), since both are sold under the name brahmi. Centella is not toxic but belongs to a different family (Apiaceae) and has rounded to reniform petiolate leaves in a rosette, clearly distinct from the small fleshy opposite leaves of Bacopa.

Processing methods on this herb card
Infusion or brief extraction in hot water; usually without long boiling.
Full method description (from the catalogue)
Here, herbal tea is prepared as an infusion: pour freshly boiling water over dried herbs or a herbal blend and steep for at least 5 minutes. BfR gives this as a hygiene rule, not a medicinal dose. Follow the specific product instructions, including a longer steeping time when stated. This rule for herbal infusions is not a general preparation guide for true tea (Camellia sinensis). Temperature, steep time, and the herb-to-water ratio change both flavour and what dissolves into the liquid.
Compared with a decoction, heat exposure is shorter and gentler; tender leaves and flowers are often better as an infusion than with prolonged simmering. For each herb, always follow the plant card for suitable plant part, preparation, and safety notes — general rules never replace species-level judgement.
Traditional context for this method: yes·Scientific context for this method: no
Filling capsules with dried herb or powder; home and industrial variants.
Full method description (from the catalogue)
A capsule is a container; it may hold plant powder or a dry extract. Equal fill weights do not mean equal constituent levels or effects. Filling capsules with powder at home is therefore not equivalent to a standardized extract.
The word "standardized" alone does not guarantee product quality. A product sold in capsules may differ from the preparation used in a study.
This page is a guide to processing forms, not a universal dosing procedure. For each herb, distinguish the plant part, powder and extract; the list below does not by itself establish suitability for home filling.
Traditional context for this method: no·Scientific context for this method: yes
Trials used standardised extracts (about 300 mg daily for 12 weeks); the commonest adverse effects were digestive — nausea, cramps, diarrhoea. The effect builds over weeks, not after a single dose.
Cooking, baking, seasoning as food — general category without therapeutic claims.
Full method description (from the catalogue)
Culinary use covers herbs as ingredients in dishes, drinks, or spice mixes. This overview does not evaluate medicinal effects — only reminds you about species intent, allergies, and heat treatment where needed (e.g. some fruits or plant parts).
Combining with alcohol, sugar, or long cooking changes outcomes; verify culinary sources.

The herb of Brahma — for those who learn the Vedas by heart
General
Traditional useFolk useHerbal loreThe name brahmi points to Brahma, the creator, and to brahman, the highest consciousness; in Ayurveda it belongs to the medhya rasayanas, agents 'for the intellect'. Tradition holds that students memorising Vedic texts took it. Beware the shared name: in parts of India 'brahmi' also means gotu kola (Centella asiatica), a botanically different plant. A record of tradition.

How to read evidence strength and study type labels
Labels summarise how the catalogue entry is tagged — they are not a medical verdict on efficacy. For every row, read the summary, limitations and source link.
Evidence strength
- Evidence level not specified
- The author did not grade the record; judge from the summary, limitations and source link.
- Narrative / orientational literature
- Descriptive or expert literature without controlled group comparison — context rather than proof of effect.
- Weak evidence
- Study or conclusion with major methodological limits; treat only as a pointer for further reading.
- Preliminary findings
- First or smaller studies — interesting direction, not the final word on efficacy or safety.
- Moderate strength of evidence
- Moderate strength by study design; sample and context limits still apply.
- Stronger evidence
- Stronger design or consistency of results within the study's stated limits.
- Review article
- A review summarises multiple sources; quality depends on review method and field.
Study type
- Narrative / expert text
- Expert text or overview without a classical study design.
- In vitro study
- Cell culture or test-tube experiment — does not show an effect in the body.
- Animal study
- Animal model — transfer to humans is not automatic.
- Observational study
- Observing groups without random treatment assignment; confounding is possible.
- Clinical trial
- Human clinical trial; sample size and control group matter.
- Randomised controlled trial
- Randomised controlled trials are among the stronger designs when well conducted.
- Review study
- A review aggregates multiple papers — quality depends on selection rules.
- Systematic review
- Systematic review with explicit search and selection methodology.
- Meta-analysis
- Statistical pooling of studies; outcome depends on input data and heterogeneity.
- Regulatory assessment / monograph (EMA, WHO…)
- Regulatory body summary for a herbal product — different context from a single RCT; often about products, not home tea.
- Expert monograph (herbal preparations)
- Structured literature summary for a plant or drug — quality depends on author and edition year.
A meta-analysis of 9 RCTs (518 people) found improved speed of attention after 12 weeks of bacopa extract — shorter Trail B times and faster choice reaction time — versus placebo; no effect was shown on memory or other cognitive domains.
