Key Constituents
The principal yellow-orange pigments and best-studied bioactive compounds, responsible for most of turmeric's anti-inflammatory and antioxidant activity; oral bioavailability is low unless combined with piperine or a lipid carrier.
Aromatic sesquiterpenes (including turmerone) contributing to fragrance and additional bioactivity.
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.
Pharmacological Actions
Anti-inflammatory and astringent for inflamed mucous membranes (sore-throat gargle, mouth)
Antimicrobial (berberine) - supports skin, mucosal and gastrointestinal infections and sore throat

Safety, Cautions & Contraindications
Generally very safe in culinary quantities. High-dose curcumin supplements may cause gastrointestinal upset. May interact with anticoagulants (warfarin), antidiabetic drugs, and acid-suppressing medications. Avoid very high doses during pregnancy and breastfeeding. Rarely causes allergic reactions.
Duke (2002) rates turmeric as +++ with clinical evidence (score 2) for anti-inflammatory activity, consistent with Commission E and WHO approvals. Curcumin is the primary bioactive compound with well-documented anti-inflammatory, antioxidant, anti-aggregant, and hepatoprotective effects. Duke notes Commission E approval for dyspeptic complaints. Dose: 1.5–3 g dried rhizome powder daily. A major pharmacological consideration is bioavailability: curcumin alone has low absorption, but combining with piperine (black pepper) increases bioavailability by up to 2000%. Contraindicated in bile duct obstruction; use with caution in gallstones and during pregnancy at medicinal doses (Duke, 2002).
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.

Botanical Description
Rhizomatous perennial herb with large, broad, lance-shaped leaves arising directly from the underground rhizome in a clump. Pale yellow flowers are borne in a dense spike partly hidden among pale green to pink upper bracts. The branching, knobbly rhizome has a bright orange-yellow interior, the source of turmeric spice and dye.[1]
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]
Habitat
Native to South Asia (India) and Southeast Asia; cultivated extensively in warm, humid tropical climates on well-drained, fertile soils.
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 rhizomes are dug at the end of the growing season, typically 8-10 months after planting, when the leaves have died back; they are cleaned, boiled or steamed, then dried and often ground into the familiar yellow powder.
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]
Traditional Uses
Turmeric rhizome is a cornerstone spice and medicine of Ayurvedic and traditional Chinese medicine, used for millennia as an anti-inflammatory, digestive and wound-healing remedy and valued as a golden dye; its curcuminoid-rich rhizome is now among the most extensively researched botanicals for inflammatory and joint conditions, directly building on this traditional reputation.[1, 13]
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
Rhizome extract standardised to curcuminoid content, often combined with piperine (black pepper extract) to improve absorption, taken as capsules; the form used in most clinical arthritis and inflammation studies.
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
Clinical trials in arthritis commonly use around 1000-1500 mg of curcumin (or curcuminoid-standardised extract) daily, in divided doses, often combined with piperine. Educational reference only, not a prescription.
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.
