Chemistry notes

  • CHEMISTRY: Relevant reported constituents include curcuminoids; turmerones; constituent presence alone does not establish clinical efficacy.

Uses & Evidence

Traditional / historical use

Documented traditional use — not a claim of established efficacy.

  • TRADITIONAL: Turmeric has been used for inflammation; digestive complaints; skin disorders; this records historical/traditional use and does not establish efficacy.

    MODERATE · evidence synthesis/fact sheet · NCCIH Herbs at a Glance

Modern evidence

  • EVIDENCE: For the major use set (inflammation; digestive complaints; skin disorders), the evidence assessment is limited/mixed: Limited/mixed meta-analyses for osteoarthritis; bioavailability and formulation heterogeneity limit inference.

    MODERATE · systematic review/meta-analysis · NCCIH Herbs at a Glance

    Mixed findings, product heterogeneity, or indirect evidence are preserved in the detailed profile.

Preparation

Forms used traditionally

decoctiontincturepowder/capsulestandardized extract

A listed form does not imply it suits every plant part, or that one preparation is interchangeable with another — see the plant’s own notes below.

  • PREPARATION: The medicinal material is rhizome; traditional and modern forms include decoction, tincture, powder/capsule, standardized extract. No dose or potency is specified.

    MODERATE · regulatory monograph · EMA European Union herbal monographs and list entries

    Preparation-specific evidence should not be generalized across extracts, teas, oils, or whole herb.

Safety

Cats & dogs

  • High risk

    Ground turmeric spice preparations have been reported to be fraudulent and/or contaminated with lead, creating a product-quality toxicity concern.

    Contamination · ORAL · ground turmeric spice · MODERATE · veterinary_manual · Herbal Medicine in Veterinary Patients - Therapeutics

  • Caution

    High doses of turmeric may cause diarrhea, flatulence, bloating, headache, or nausea; turmeric may also increase bleeding risk when combined with NSAIDs.

Additional safety notes (general, unstructured)

Free-text safety notes carried from their source — not broken out by species, route, or hazard type, and not equivalent to the structured records above. Each note names the kind of source it came from.

  • SAFETY: Major issues include GI upset; gallbladder stimulation; rare clinically apparent liver injury, especially enhanced-bioavailability products. Contraindications/cautions include Biliary obstruction or gallstones; liver disease caution.

    HIGH · observational/case series and expert review · LiverTox: Herbal and Dietary Supplements

  • SAFETY: Clinically relevant interaction concerns include Potential additive anticoagulant and glucose-lowering effects; piperine formulations may alter drug exposure.

    MODERATE · observational/case series and expert review · LiverTox: Herbal and Dietary Supplements

    Some interactions are theoretical or based on case reports/pharmacokinetics rather than outcome trials.

  • SAFETY: Pregnancy/lactation reference: Insufficient medicinal-dose pregnancy/lactation safety data.

    MODERATE · regulatory monograph or evidence synthesis · NCCIH Herbs at a Glance

    Absence of evidence is not evidence of safety.

  • Ground turmeric spice preparations have been reported to be fraudulent and/or contaminated with lead, creating a product-quality toxicity concern.

    MODERATE · veterinary_manual · Herbal Medicine in Veterinary Patients - Therapeutics

    The concern applies to contaminated or fraudulent preparations rather than necessarily to authentic turmeric.

  • High doses of turmeric may cause diarrhea, flatulence, bloating, headache, or nausea; turmeric may also increase bleeding risk when combined with NSAIDs.

    MODERATE · veterinary_manual · Herbal Medicine in Veterinary Patients - Therapeutics

    Species and route were not specified; curcumin was named as a studied constituent, not explicitly as a toxic constituent.

Identity

  • Possible adulterantSaffron

    Turmeric material/colorants are documented botanical adulterants of powdered saffron.

    Why it matters: Adulteration dilutes or replaces Crocus stigmas and invalidates identity, composition, and dosing.

  • Synonym

    GBIF resolves Curcuma domestica Valeton as a synonym of Curcuma longa. The older name still appears in herbal and taxonomic literature.
