Key Constituents
Pharmacological Actions
Bacopa monnieri (Brahmi) extract and its saponins (bacopaside II, bacopasaponins) inhibit proliferation and induce apoptosis in colon and lung cancer cells (preclinical).
Anti-inflammatory and antioxidant
Traditional & Indicated Uses
inferred from anti-inflammatory action
Bacopaside II from Bacopa monnieri inhibits colon cancer cell growth via cell-cycle arrest and apoptosis (aquaporin-1 blockade), and its bacopasaponins are cytotoxic to lung (PC9) and colon (SW620) cancer cells (preclinical).
inferred from neuroprotective action

Traditional expectorant for cough and respiratory complaints (iridoid glycosides inhibit lung inflammation) - a standardised extract suppressed COX-2 and eotaxin via the NF-kB pathway in human lung epithelial cells
Mild digestive / stomach tonic (indigestion)

Soothing for skin irritation (topical)
Safety, Cautions & Contraindications
Generally well tolerated at standard doses. The most commonly reported side effects are gastrointestinal — nausea, stomach cramps, and increased bowel movements — which can be reduced by taking with food. Not recommended during pregnancy. May interact with medications that increase acetylcholine levels (e.g. Alzheimer's medications). Use with caution in thyroid conditions, as bacopa may increase thyroid hormone levels.
Traditional use only; clinical evidence is limited, so a persistent cough or digestive complaint needs medical assessment. Safety in pregnancy and breastfeeding is not established.

Botanical Description
Low, creeping, succulent perennial herb that roots at the nodes as it spreads across wet ground. The leaves are small, fleshy, spatula-shaped and arranged oppositely along the trailing stems. Small, pale lavender to white, four- to five-petalled flowers are borne singly in the leaf axils.[4]
Low, creeping, mat-forming perennial herb with softly hairy, oval, finely toothed leaves along trailing stems that root as they spread. Small, pale lilac-blue flowers with darker veining are borne in slender upright spikes rising from the leaf axils.[8]
Habitat
Grows in wet, marshy ground, muddy shorelines, rice paddies and shallow water throughout tropical and subtropical regions of Asia, and also found in parts of Africa, Australia and the Americas.[4]
Grows on dry heath, moorland, open woodland, grassland and banks on acidic, well-drained soils; native to Europe and naturalised in North America.[8]
Harvesting
The whole plant (leaf and trailing stem) is harvested during active growth, typically cut a few centimetres above the mud or water line, and dried or used fresh.
The flowering aerial parts are cut in summer while in flower and dried in a warm, shaded, airy place; the closely related Veronica chamaedrys is a frequent adulterant, so careful identification (or a reputable source) is important.[8]
Traditional Uses
Bacopa (brahmi) is a classic Ayurvedic 'medhya rasayana' (brain-nourishing) herb, traditionally used to support memory, learning and mental clarity, and as a calming nervine for anxiety and disturbed sleep. This traditional cognitive reputation is now supported by randomised controlled trials of standardised extracts.[1, 4]
Speedwell has a long European folk history as a mild digestive tonic and traditional expectorant for cough and respiratory complaints, and has also been used topically as a soothing wash for irritated skin; modern research on its iridoid glycosides supports a molecular basis for the traditional respiratory use.
