Key Constituents

Curcuminoids (curcumin, demethoxycurcumin, bisdemethoxycurcumin)[1, 13]

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.

Curcumin
Essential (volatile) oil

Aromatic sesquiterpenes (including turmerone) contributing to fragrance and additional bioactivity.

Safety, Cautions & Contraindications

Safety note[13, 14, 15]Caution

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.

Safety note[13, 14, 15, 16]Caution

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).

Safety note[8]Info

Tannin-rich: high or prolonged intake may cause stomach upset or constipation and can reduce the absorption of iron and some medicines taken at the same time.

Safety note[8]Info

Traditional use only; diarrhoea that persists (especially in children) needs medical assessment and attention to rehydration.

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]

Height: 60-100 cm
Habit: Rhizomatous perennial herb
Leaves: Large, broad, lance-shaped, arising directly from the rhizome
Flowers: Pale yellow, in a dense spike among pale green to pink upper bracts
Stem: Pseudostem formed by tightly overlapping leaf bases
Root: Branching, knobbly rhizome with a bright orange-yellow interior
Fruit: Rarely sets seed; propagated by rhizome division
Flowering Period: Summer to early autumn

Scrambling, thorny deciduous shrub (Rosaceae) forming dense thickets, with arching prickly stems that root at the tip. Leaves are palmately compound, usually with 3-5 toothed leaflets. White to pale pink, five-petalled flowers are followed by clusters of small drupelets forming the blackberry fruit, ripening from red to glossy black.[8]

Height: Scrambling/arching canes, typically 1-3 m
Habit: Scrambling, thorny, thicket-forming shrub
Leaves: Palmately compound, usually 3-5 toothed leaflets
Flowers: White to pale pink, five-petalled
Stem: Arching, prickly, rooting at the tip
Root: Woody perennial root system
Fruit: Cluster of drupelets, ripening red to glossy black
Flowering Period: June-August

Habitat

Native to South Asia (India) and Southeast Asia; cultivated extensively in warm, humid tropical climates on well-drained, fertile soils.

Native throughout Europe and widely naturalised elsewhere, an aggressive coloniser of hedgerows, woodland edges, scrub and waste ground. 'Rubus fruticosus' is a taxonomically complex aggregate comprising hundreds of closely related microspecies.[8]

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.

Parts: Rhizome
Season: End of growing season, 8-10 months after planting

Leaves are picked fresh throughout the growing season and dried for tea; berries are picked in late summer once fully ripe.[8]

Parts: Leaf
Season: Leaf throughout the growing season

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]

Blackberry leaf has a long European folk-medicine tradition as an astringent gargle for sore throat and mouth ulcers, and as a remedy for mild diarrhoea, reflecting its high tannin content; the berries themselves are valued as a nutritious, antioxidant-rich food.[8]

Preparations

Standardised extract[1]

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.

Infusion (tea)[8]

Dried leaf steeped in hot water, taken internally or used as a gargle/mouthwash.

Gargle/mouthwash[8]

A stronger leaf infusion used topically for sore throat and mouth irritation.

Dosage

Standardised extract[1]

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.

Infusion (tea)[8]

Traditional guidance suggests roughly 2-4 g dried leaf per cup as an infusion, up to three times daily, or used as a gargle at similar strength. Educational reference only, not a prescription.

Drug Class Interactions

Safety note[17]Caution
Drug Class: anticoagulants-antiplatelets
Mechanism: Turmeric/curcumin can raise the blood levels of blood-thinning drugs such as warfarin and clopidogrel and has mild antiplatelet activity, so combined use should be monitored for increased bleeding risk.

Safety note[18, 19, 20]Caution
Drug Class: antidiabetics
Mechanism: Turmeric/curcumin can lower blood glucose and HbA1c in people with type 2 diabetes (confirmed by meta-analysis of randomised trials); combined with diabetes medicines it may add to blood-sugar lowering, so monitor blood sugar.
