Key Constituents

Diterpenoid lactones[2, 3, 10, 11]

Andrographolide is the principal active compound; also neoandrographolide and deoxyandrographolide.

Flavonoids[11]

Antioxidant and anti-inflammatory constituents.

Flavonoids
Polyphenols and other phenolics[11]

Contribute to antioxidant activity.

Phenolic compounds
Isoquinoline alkaloids - berberine (principal), hydrastine and canadine[1, 4, 12]

Berberine is the main antimicrobial, hypoglycaemic and hypolipidaemic constituent. Notably, whole-leaf extracts are more potent against MRSA than isolated berberine (owing to efflux-pump-inhibitory flavonoids) and show quorum-quenching, anti-virulence activity.

Safety, Cautions & Contraindications

Safety note[10, 17]Caution

Avoid in pregnancy and when trying to conceive: high doses have shown reproductive toxicity in animals and the herb has a traditional reputation as an abortifacient.

Safety note[10]Caution

High doses have caused nephrotoxicity and reproductive toxicity in studies; use standardized products at recommended doses and avoid prolonged high-dose use.

Safety note[10, 17]Caution

May lower blood pressure and blood sugar and may interact with anticoagulant/antiplatelet, antihypertensive and immunosuppressant medicines; allergic reactions can occur.

Safety note[1]Caution

Contraindicated in pregnancy and breastfeeding: berberine crosses the placenta and into milk and can cause or worsen newborn jaundice (risk of kernicterus); do not give to infants.

Safety note[1, 14]Caution

Berberine strongly inhibits drug-metabolising enzymes (especially CYP3A4 and CYP2D6), so it can raise the blood levels of many medicines - a significant herb-drug-interaction risk. In a screen of commercial herbal products, goldenseal was among the most potent CYP2D6 inhibitors and also inhibited CYP3A4. High doses have shown possible liver, nerve and photo-toxicity.

Botanical Description

Erect, branching annual herb with a slender, quadrangular (square-sectioned), dark green stem. The leaves are opposite, lance-shaped and glabrous, with a short stalk. Small, two-lipped, white flowers with purple-pink markings are borne in loose, spreading axillary and terminal racemes. The whole plant, and especially the leaves, is intensely and characteristically bitter.[11]

Height: 30-110 cm
Habit: Erect, branching annual herb
Leaves: Opposite, lance-shaped, glabrous, short-stalked
Flowers: Small, two-lipped, white flowers marked with purple-pink, in loose spreading racemes
Stem: Slender, quadrangular (square in cross-section), dark green, branching
Root: Shallow, fibrous root system
Fruit: Small, elastically dehiscent capsule
Flowering Period: September-December (varies by climate)

Low, woodland perennial herb rising from a knotted, bright yellow rhizome with wiry yellow roots. Each stem bears two ragged, palmately lobed, maple-like leaves and a single small, inconspicuous greenish-white flower, followed by a raspberry-like cluster of red berries.[1]

Height: 15-30 cm
Habit: Low, woodland perennial herb
Leaves: Two per stem, ragged, palmately lobed, maple-like
Flowers: Single, small, inconspicuous, greenish-white, petal-less
Stem: Hairy, upright, bearing two leaves
Root: Knotted, bright yellow rhizome with wiry yellow roots (the medicinal part)
Fruit: Raspberry-like cluster of red berries
Flowering Period: April-May

Habitat

Native to India and Sri Lanka and widely distributed through South and Southeast Asia, growing wild in plains, hillsides, roadsides and cultivated fields; also grown commercially as a medicinal crop.[11]

Grows in rich, shaded deciduous woodland with humus-rich soil; native to eastern North America, now scarce in the wild due to overharvesting and largely supplied by cultivation.[1]

Harvesting

The aerial parts (leaves and tender stems) are cut just before or at the onset of flowering, when andrographolide content is typically highest, and dried in shade to preserve the bitter diterpenoid lactones.[11]

Parts: Aerial parts (leaves and herb)
Season: Before to early flowering

The rhizome and root are dug in autumn from plants at least three to four years old, when berberine content is highest, then cleaned and dried; because wild populations are depleted, cultivated or sustainably sourced material is strongly preferred, and careful identification against the toxic mayapple and bloodroot, which share its woodland habitat, is essential before any wild-harvesting.[1]

Parts: Rhizome and root
Season: Autumn, from mature (3-4+ year) plants

Traditional Uses

Andrographis, the 'king of bitters', is a cornerstone bitter tonic of Ayurvedic and traditional Chinese medicine (Chuan xin lian), used for fevers, colds, sore throat, infections and liver complaints. This traditional reputation for treating the common cold and upper respiratory infections is now supported by clinical trials of standardised extracts.[10, 12]

Goldenseal root has a Native American and, after adoption by Eclectic physicians, wider North American tradition as a bitter tonic and antimicrobial remedy for mucous-membrane infections, sore throat, digestive upset and topical skin infections, directly reflecting its high berberine content.[1]

Preparations

Infusion/decoction[11]

Dried aerial parts infused or lightly decocted in hot water as a very bitter traditional fever and cold remedy.

Standardised extract[10, 12]

Extract standardised to andrographolide content, taken as tablets or capsules; the form used in most clinical trials for cold/URTI symptom relief.

Decoction[1]

Dried rhizome and root simmered in water as a traditional bitter antimicrobial tea, or used as a gargle for sore throat.

Tincture[13]

Tincture 1:10 in 60% ethanol of the dried rhizome and root, 2-4 ml three times daily per the WHO monograph Rhizoma Hydrastis. Educational reference only, not a prescription.

Standardised extract[4]

Extract standardised to berberine/hydrastine content, taken as capsules; whole-leaf extracts have shown stronger antimicrobial activity than isolated berberine in some studies.

Dosage

Standardised extract[10, 12]

Clinical trials for upper respiratory infection commonly use extracts standardised to around 60-120 mg andrographolide daily, in divided doses, for up to 5-7 days. Educational reference only, not a prescription.

Dried herb[13]

The WHO monograph on Herba Andrographidis gives, by indication - for the common cold, 1.5-3.0 g of the powdered crude drug three times daily, after meals and at bedtime; for pyrexia, a decoction from 3 g of the crude drug twice daily; for diarrhoea, a decoction from 3-9 g as a single dose as needed, or two 500 mg tablets four times daily. Note that the EMA HMPC assessed this herb and issued a public statement rather than a monograph, so there is no EU posology. Educational reference only, not a prescription.

Decoction/tincture[13]

The WHO monograph on Rhizoma Hydrastis gives a daily dose of 0.5-1.0 g of the dried rhizome and root three times, or taken as a decoction; a 1:1 liquid extract in 60% ethanol at 0.3-1.0 mL three times; or a 1:10 tincture in 60% ethanol at 2-4 mL three times. For short-term use only, given goldenseal's potent CYP-enzyme inhibition and its contraindication in pregnancy. Educational reference only, not a prescription.

Drug Class Interactions

Not documented

Safety note[15, 16]Caution
Drug Class: cyp3a4-substrates
Mechanism: Goldenseal's berberine and hydrastine strongly inhibit CYP3A4 (and also CYP2D6), enzymes that clear many medicines. In a controlled study in healthy volunteers, 28 days of goldenseal cut CYP3A4/5 and CYP2D6 activity by roughly 40%, so it can raise the blood levels and side effects of drugs handled by these pathways - for example some statins, calcium-channel blockers and sedatives (CYP3A4), and certain antidepressants, beta-blockers and opioids (CYP2D6). Separate dosing and monitor, or avoid combining with narrow-margin medicines.

Safety note[17]Caution
Drug Class: antidiabetics
Mechanism: Goldenseal is rich in berberine, its main alkaloid, which lowers blood glucose - meta-analyses of randomised trials show berberine significantly reduces fasting glucose and HbA1c. Taken with diabetes medicines, goldenseal may therefore add to blood-sugar lowering, so monitor blood glucose.

Dangerous Lookalikes

Not documented

Safety note[18, 19]Dangerous
Dangerous Plant: podophyllum-peltatum
Confused Part: Woodland rhizome dug as goldenseal; mayapple shares the same rich woods and has similar lobed, maple-like leaves.
Confusion Context: Goldenseal (Hydrastis canadensis) is dug from rich woodland for its yellow rhizome. Mayapple (Podophyllum peltatum) grows in the same rich-woods habitat and, once its leaves expand, its lobed maple-like leaves resemble goldenseal, so novice foragers confuse them. Mayapple contains podophyllotoxin (a potent cell poison) in all parts except the ripe fruit; ingestion causes severe vomiting and diarrhoea and can cause serious systemic toxicity. Because the plants share habitat and leaf shape, this is a genuine hazard when digging goldenseal.
Distinguishing Features: Whole plant: goldenseal has a hairy upright stem bearing usually two ragged, maple-like lobed leaves and a single small flower, with a knotted BRIGHT-YELLOW rhizome. Mayapple has one or two large, smooth, umbrella-like lobed leaves on a hairless stalk and a white flower nodding beneath, with a white-ish creeping rhizome., Rhizome colour (decisive): goldenseal's rhizome and root are vivid yellow inside (berberine). Mayapple's rhizome is not bright yellow., Leaf texture: goldenseal leaves are hairy and puckered; mayapple leaves are large, smooth and shield-like (the stalk joins near the centre).
Key Test: Dig only after matching the whole plant, and check the rhizome. A hairy stem with ragged maple-like leaves over a BRIGHT-YELLOW knotted rhizome = goldenseal. Large smooth umbrella-like leaves over a pale rhizome (no yellow) = mayapple - toxic, do not use. If the root is not bright yellow inside, do not use it.

Safety note[18, 20]Dangerous
Dangerous Plant: sanguinaria-canadensis
Confused Part: Woodland rhizome dug as goldenseal; bloodroot grows in the same rich woods and its rhizome is gathered in mistake for goldenseal.
Confusion Context: Bloodroot (Sanguinaria canadensis) shares the same rich-woods spring habitat as goldenseal and is listed among goldenseal's harvesting look-alikes. Bloodroot is a high-severity poison: its rhizome contains isoquinoline alkaloids (sanguinarine) and, when broken, oozes a bright red-orange sap; ingestion causes vomiting, faintness, dizziness, dilated pupils and, in serious cases, heart failure, and the sap is destructive to tissue. Because both are dug for their rhizomes from the same woodland, this is a genuine hazard.
Distinguishing Features: Sap colour (decisive): a broken bloodroot rhizome bleeds a bright RED-ORANGE sap. Goldenseal's rhizome is BRIGHT YELLOW inside, not red., Leaf: bloodroot has a single, rounded, deeply scalloped/lobed grey-green leaf that wraps the flower stalk, and a white flower; goldenseal has a hairy stem with two ragged maple-like leaves., Whole plant: confirm goldenseal by its paired hairy maple-like leaves and yellow root before digging.
Key Test: Break the rhizome and look at the sap and leaves. Bright YELLOW root with paired hairy maple-like leaves = goldenseal. A single scalloped leaf and a rhizome bleeding RED-ORANGE sap = bloodroot - a high-severity poison, do not use. If the sap is red, it is not goldenseal.
