Safety, Cautions & Contraindications

Safety note[13, 16, 17]Caution

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.

Safety note[13, 16, 17, 18]Info

Duke (2002) does not include a dedicated entry for Bacopa monnieri (water hyssop/brahmi) in the Handbook of Medicinal Herbs, Second Edition.

Safety note[12]Caution

Avoid internal use in pregnancy and breastfeeding: like goldenseal, the berberine it contains can cross the placenta and into milk and worsen newborn jaundice (kernicterus risk).

Safety note[11, 12]Caution

Berberine impairs the metabolism of some medicines - for example it raises blood levels of cyclosporine, risking toxicity - so use caution with prescription drugs. It is used mainly topically for skin conditions.

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]

Height: 5-15 cm (trailing/creeping)
Habit: Low, creeping, succulent perennial herb
Leaves: Small, fleshy, spatula-shaped, opposite
Flowers: Small, pale lavender to white, four- to five-petalled, borne singly in leaf axils
Stem: Trailing, succulent, rooting at the nodes
Root: Fine roots at each node along the creeping stem
Fruit: Small ovoid capsule
Flowering Period: Year-round in warm, wet climates

Evergreen shrub, 0.5-2 m tall, spreading by underground rhizomes to form thickets. The pinnate leaves resemble holly, with 5-9 glossy, dark green, spiny-toothed leaflets that often turn bronze-red in winter. Small, bright yellow, six-petalled flowers are borne in dense, upright terminal racemes in early spring, followed by clusters of blue-black, grape-like berries with a waxy bloom. The wood and inner bark of the stem and root are bright yellow when cut, owing to their high content of berberine-type alkaloids.

Height: 0.5-2 m
Habit: Evergreen, rhizomatous, colony-forming shrub
Leaves: Pinnate, holly-like, 5-9 glossy dark green spiny-toothed leaflets
Flowers: Small, bright yellow, six-petalled, in dense upright terminal racemes
Stem: Woody; wood and inner bark bright yellow when cut
Root: Woody, rhizomatous, bright yellow within (berberine-type alkaloids)
Fruit: Clusters of blue-black, grape-like berries with a waxy bloom
Flowering Period: Early spring (March-April)

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 Pacific Northwest of North America, growing in coniferous woodland understorey, forest margins and rocky slopes; widely introduced and naturalised as an ornamental and hedging shrub in temperate regions elsewhere.

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.

Parts: Leaf, Whole Plant
Season: During active growth (warm season)

The root and root bark, the medicinal parts, are dug from established plants - traditionally in autumn - and dried. Because wild populations are slow-growing, cultivated or nursery-sourced material is preferred over wild-harvesting.

Parts: Root, Bark
Season: Autumn

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]

Oregon grape root has a traditional Native American and Eclectic-medicine history as a bitter tonic and alterative (blood-purifying) remedy and for skin conditions. Its main modern use, supported by clinical trials, is topical application of a standardised bark extract for mild-to-moderate psoriasis and atopic dermatitis (eczema), where its berberine-type alkaloids give anti-inflammatory and antiproliferative effects on skin cells.[1, 11, 12]

Preparations

Standardised extract[1, 4]

Extract standardised to bacoside content, taken as capsules or tablets; the form used in most clinical trials for cognitive support.

Topical cream/ointment[1, 11, 13]

A standardised 10% Mahonia aquifolium bark extract cream, the best-studied form, applied to affected skin up to three times daily for psoriasis or eczema.

Dosage

Standardised extract[1, 4]

Clinical trials for cognitive support commonly use extracts providing around 300 mg dried extract daily, taken for at least several weeks, since benefits accrue gradually. Educational reference only, not a prescription.

Topical 10% extract cream[11, 13]

Clinical trials in psoriasis and eczema have used a 10% Mahonia aquifolium bark extract cream applied to affected areas up to three times daily. Educational reference only, not a prescription; internal use is not well studied and should be supervised.

Drug Class Interactions

Safety note[19, 20]Caution
Drug Class: sedatives-cns-depressants
Mechanism: Bacopa (brahmi) is traditionally used as a calming, sedative herb; taken with sedatives, sleeping tablets or other central-nervous-system depressants (including alcohol) it may add to drowsiness and slowed reactions.
