Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
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.
The pungent phenolic constituents of the rhizome (notably 6-gingerol, which dehydrates to 6-shogaol on drying) responsible for ginger's antiemetic and anti-inflammatory activity; a standardized regimen of 84 mg/day gingerols/shogaols was effective against chemotherapy-induced nausea.

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).
Ginger is widely considered safe at culinary and conventional supplemental doses. At high doses (>5 g/day), ginger may cause heartburn, acid reflux, mouth irritation, and mild gastrointestinal discomfort. Ginger may modestly inhibit platelet aggregation and enhance the effects of anticoagulants (e.g., warfarin) — clinical significance at dietary amounts is low, but caution is warranted with high-dose supplementation alongside blood-thinning medications (Shalansky et al., 2007). May lower blood sugar — monitor closely if combining with antidiabetic medications.
Pregnancy: Ginger is among the most studied herbal remedies for pregnancy nausea. At doses up to 1 g/day, it is generally considered safe and effective for nausea and vomiting of pregnancy (NVP), based on multiple RCTs. The EMA monograph supports its use for NVP. Avoid doses >1.5 g/day during pregnancy due to theoretical concern about anticoagulant activity. Breastfeeding: generally considered safe at food amounts; limited data for medicinal doses (European Medicines Agency, 2012a).
Duke (2002) rates ginger as a triple-plus herb (+++) with strong clinical support (score 3) for antiemetic activity, including motion sickness, morning sickness, and postoperative nausea, and score 2 evidence for dyspepsia, diarrhea, and inflammation. Typical doses are 2-4 g dry rhizome per day or 500-1000 mg fresh root three times daily; Commission E approves ginger for dyspepsia and motion sickness. Ginger has antiplatelet properties and should be used with caution alongside anticoagulant medications (Duke, 2002).

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]
Rhizomatous perennial herb with narrow, lance-shaped leaves arising in two ranks from slender, reed-like pseudostems. Pale yellow-green flowers with purple markings are borne in a dense, cone-like spike on a separate short stalk arising directly from the rhizome, though ginger rarely flowers in cultivation. The branching, knobbly rhizome has a pale yellow interior and a characteristic pungent, spicy aroma.[1]
Habitat
Native to South Asia (India) and Southeast Asia; cultivated extensively in warm, humid tropical climates on well-drained, fertile soils.
Believed native to tropical Southeast Asia; cultivated extensively throughout the tropics and subtropics (India, China, Nigeria, the Caribbean) in warm, humid conditions on well-drained, fertile soil.
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 is dug 8-10 months after planting, once the leaves have died back, for mature ('old') ginger with the fullest pungency, or earlier for milder young ('green') ginger; cleaned and used fresh or dried and ground.
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]
Ginger rhizome has one of the longest and most widespread medicinal histories of any spice, used across Chinese, Ayurvedic and Western herbal traditions as a warming digestive carminative, an antiemetic for nausea and motion sickness, and an anti-inflammatory remedy for joint pain; this traditional reputation is now supported by an extensive clinical evidence base, particularly for nausea (including pregnancy and chemotherapy-related) and osteoarthritis.[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 powder or standardised extract, taken as capsules for nausea or joint-pain 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.
Clinical trials for nausea commonly use around 1-1.5 g of dried rhizome powder daily, in divided doses (up to 1 g/day in pregnancy); osteoarthritis studies commonly use similar or somewhat higher doses. Educational reference only, not a prescription.
