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).
Adaptogen for stress and anxiety (improves stress scores and well-being in trials)
Cognitive support - a placebo-controlled study in healthy adults found improved reaction time and accuracy and shorter P300 latency
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
inferred from anti-inflammatory action

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.
Generally well tolerated; mild nausea has been reported. Its blood-sugar-lowering effect means caution alongside antidiabetic medicines.

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]
Aromatic annual or short-lived perennial subshrub (Lamiaceae), 30-75 cm tall, with erect, much-branched, hairy stems often tinged purple. Leaves are opposite, ovate-oblong with a toothed margin, and release a strong, clove-like (eugenol) scent when crushed. Small purplish-pink, two-lipped flowers are borne in elongated terminal racemes. The plant is held sacred in Hindu tradition (Tulsi).[11]
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]
Native to the Indian subcontinent and tropical Asia, now cultivated and naturalised throughout the tropics and subtropics worldwide; commonly grown in home gardens and temple courtyards as well as cultivated as a medicinal and aromatic crop.[12]
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.
Leaves are harvested year-round from actively growing plants, ideally picked once morning dew has dried; whole flowering tops are also gathered.
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]
Tulsi is one of the most revered plants in Ayurvedic medicine, traditionally used as an adaptogen for stress, a remedy for respiratory complaints (colds, cough, asthma), and a general immune tonic. Modern clinical trials support adaptogenic/anti-stress, blood-sugar-lowering and immunomodulatory effects consistent with these traditional uses.[3, 12]
Preparations
Dosage
Clinical trials for stress and mood have used standardised dry-extract capsules taken over several weeks; dosing varies by product concentration, so follow the manufacturer's guidance. Educational reference only, not a prescription.
The WHO monograph on Folium Ocimi Sancti gives a daily dosage of 6-12 g of the crude drug as a decoction. This is a whole-day total for the fresh or dried leaf, notably higher than the 1-2 g per cup often quoted in popular sources. Educational reference only, not a prescription.
