Naga Yellow (Curcuma longa)

Naga Yellow (Curcuma longa) is a turmeric variant containing curcumin as its primary bioactive compound. Curcumin modulates inflammatory pathways through inhibition of NF-κB signaling and cyclooxygenase enzymes.

Origin & History

Naga Yellow is a cultivar variant of Curcuma longa (turmeric), a rhizomatous herbaceous perennial plant belonging to the ginger family. While the research dossier does not provide specific information about Naga Yellow as a distinct cultivar, it would be cultivated using standard turmeric growing methods in tropical climates. Without specific research data on this cultivar variant, its unique properties cannot be determined from the available information.

Historical & Cultural Context

The research dossier does not contain information about traditional or historical use of Naga Yellow specifically. While Curcuma longa has documented traditional uses, this specific cultivar's cultural context cannot be established from the available horticultural information.

Health Benefits

• No clinical evidence available in the research dossier
• No meta-analyses or RCTs provided
• No mechanism of action studies included
• No safety or efficacy data presented
• Evidence quality: Not assessed due to lack of clinical research

How It Works

Naga Yellow turmeric's curcumin inhibits nuclear factor-κB (NF-κB), a key inflammatory transcription factor. The compound also suppresses cyclooxygenase-2 (COX-2) and lipoxygenase enzymes involved in prostaglandin synthesis. Additional mechanisms include modulation of tumor necrosis factor-alpha and interleukin-6 production.

Scientific Research

The research dossier contains no clinical trials, meta-analyses, or PMIDs related to Naga Yellow or Curcuma longa's biomedical properties. Without access to peer-reviewed clinical literature, no evidence-based health claims can be made.

Clinical Summary

No specific clinical trials have been conducted on Naga Yellow turmeric as a distinct variety. General curcumin research includes randomized controlled trials with 500-1000mg daily doses showing modest anti-inflammatory effects. Most studies focus on standardized curcumin extracts rather than specific turmeric cultivars. Evidence quality for this particular variant remains insufficient due to lack of dedicated research.

Nutritional Profile

Naga Yellow (Curcuma longa) is a turmeric variety with a nutritional profile characteristic of dried turmeric rhizome powder. Key macronutrients per 100g dried powder: carbohydrates ~65g (including starch ~40-50g, dietary fiber ~13g), protein ~8g, fat ~10g (including essential fatty acids). Micronutrients: potassium ~2525mg, iron ~55mg, manganese ~19mg, magnesium ~208mg, phosphorus ~299mg, calcium ~183mg, zinc ~4.5mg, copper ~0.6mg. Vitamins: vitamin C ~26mg, vitamin B6 ~1.8mg, niacin ~5.1mg, riboflavin ~0.23mg, folate ~20mcg. Primary bioactive compounds: curcuminoids comprising 2-5% by weight (curcumin as dominant fraction at ~75% of total curcuminoids, alongside demethoxycurcumin and bisdemethoxycurcumin); volatile essential oils ~3-7% including turmerone, ar-turmerone, and zingiberene; polysaccharides (ukonan types). Bioavailability note: curcumin exhibits inherently poor oral bioavailability (<1% absorption) due to low aqueous solubility and rapid hepatic metabolism to glucuronide and sulfate conjugates; co-administration with piperine (black pepper extract, 20mg per 2g curcumin) increases bioavailability by approximately 2000% by inhibiting hepatic and intestinal glucuronidation. Lipid-based or phospholipid complexed formulations (phytosomes) also significantly enhance absorption. The 'Naga Yellow' designation likely refers to a regional cultivar from Northeast India with potentially elevated curcuminoid concentration compared to standard commercial turmeric varieties, though specific cultivar-level compositional data remains limited in published literature.

Preparation & Dosage

No clinically studied dosage ranges are available in the provided research. Without pharmacological or clinical trial data, appropriate dosing cannot be determined. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Cannot be determined without bioavailability or interaction studies

Safety & Interactions

Turmeric may increase bleeding risk when combined with anticoagulant medications like warfarin. High doses can cause gastrointestinal upset including nausea and diarrhea in sensitive individuals. Turmeric may enhance blood sugar-lowering effects of diabetes medications, requiring monitoring. Pregnant women should avoid therapeutic doses due to potential uterine stimulant effects.
