Key Constituents
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.
Now regarded as the main antidiabetic principles.
A mixture of two sterol glucosides, historically credited with the hypoglycaemic effect.
An insulin-like polypeptide of the fruit and seed.
A pyrimidine glycoside that can trigger favism in G6PD-deficient people.
Pharmacological Actions

Safety, Cautions & Contraindications
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.
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.
Avoid in pregnancy: bitter melon can stimulate the uterus and has been associated with miscarriage; also avoid during breastfeeding.
Strong blood-sugar-lowering action: used with insulin or other diabetes medicines it can cause hypoglycaemia - monitor blood glucose and seek medical advice.
People with glucose-6-phosphate dehydrogenase (G6PD) deficiency should avoid the seeds, which contain vicine and can cause favism (haemolytic anaemia). Excessive intake may cause abdominal pain and diarrhoea.

Botanical Description
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]
Climbing or trailing annual vine (Cucurbitaceae) that climbs by simple tendrils, typically 2-5 m long. Leaves are alternate, long-stalked and palmately lobed with 5-7 deep, toothed lobes. Flowers are small, yellow and five-petalled, male and female flowers separate on the same plant. The fruit is an oblong, warty-skinned gourd that ripens from green to orange-yellow and splits open to reveal seeds coated in a bright red aril; the unripe green fruit is the part used medicinally and as food.
Habitat
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]
Likely native to tropical Asia (possibly the Indian subcontinent), now widely cultivated across tropical and subtropical Asia, Africa, the Caribbean and increasingly the Americas as a vegetable and medicinal crop; needs warmth, full sun and a trellis or support to climb.[11]
Harvesting
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]
The fruit is harvested unripe, while still green and firm, before it yellows and splits, for use as a vegetable and in traditional antidiabetic preparations; leaves are also traditionally gathered.[11]
Traditional Uses
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]
Bitter melon has a long history in Asian, African and Caribbean traditional medicine as a bitter digestive tonic and mild laxative, and most notably as a remedy for diabetes and its complications; this traditional antidiabetic use is now the most scientifically supported of its properties, with numerous studies on its blood-glucose- and lipid-lowering effects.[4, 11]
Preparations
Dried rhizome and root simmered in water as a traditional bitter antimicrobial tea, or used as a gargle for sore throat.
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.
Extract standardised to berberine/hydrastine content, taken as capsules; whole-leaf extracts have shown stronger antimicrobial activity than isolated berberine in some studies.
Dosage
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.
Clinical trials studying bitter melon for blood-sugar support have used standardised fruit extract or juice preparations taken daily over several weeks; dosing varies by product. Because it can lower blood glucose, monitor levels closely if combining with diabetes medication. Educational reference only, not a prescription.
