Indian nigella seeds, particularly the kalonji variety, contain consistently high levels of thymoquinone (30-48% in essential oil) due to optimal growing conditions and traditional cultivation methods. The seeds undergo rigorous quality testing for pharmaceutical parameters including heavy metals, microbiology, and active compound content, making them suitable for nutraceutical and therapeutic applications with proper documentation for global regulatory compliance.

Thymoquinone is the primary bioactive compound in nigella seed essential oil, comprising 30-48% of the volatile oil content. It's responsible for most therapeutic properties including anti-inflammatory, antioxidant, antimicrobial, and potential anti-cancer effects. Our seeds are tested for thymoquinone content to ensure consistent therapeutic potency, making them valuable for pharmaceutical and nutraceutical applications where standardized active compounds are required.

We maintain strict quality protocols through pre-qualified supplier networks, standardized harvesting and processing guidelines, comprehensive testing for physical, chemical, and microbiological parameters, and regular supplier audits. All batches undergo thymoquinone content analysis, heavy metal testing, and microbiological screening. Our merchant export model allows us to select the best quality from multiple sources while maintaining consistent specifications across all shipments.

Minimum orders: 500kg for whole seeds, 250kg for powder, 100kg for pharmaceutical grade. We provide complete regulatory documentation including FDA GRAS status confirmation, EU Novel Food compliance, organic certificates (NPOP/EU/USDA), quality analysis reports with thymoquinone content, heavy metals testing, and microbiological reports. All shipments include certificates of origin, phytosanitary certificates, and market-specific documentation required for import clearance.

Yes, we supply pharmaceutical-grade nigella seeds processed in GMP-certified facilities with comprehensive testing including thymoquinone quantification, heavy metals analysis (Lead <2ppm, Cadmium <0.3ppm), microbiological testing (Salmonella absent, E.coli <10 cfu/g), and pesticide residue screening. Certifications include FSSAI, ISO 22000, HACCP, and organic certifications. Each batch comes with detailed Certificate of Analysis suitable for pharmaceutical and nutraceutical applications.

Nigella seeds (Nigella sativa) and black cumin are the same product with different common names. However, there's often confusion with "true" cumin (Cuminum cyminum) which is a different species. Genuine nigella seeds are small, angular, deep black seeds from the Ranunculaceae family with distinctive therapeutic properties due to thymoquinone content. We ensure proper botanical identification and provide certificates confirming Nigella sativa species for all our shipments.

Whole nigella seeds have a shelf life of 24 months when stored properly, while ground powder maintains quality for 12 months. Optimal storage requires cool, dry conditions (temperature <25°C, humidity <60%), protection from light and heat, and pest-free environment. We recommend airtight containers and first-in-first-out inventory rotation. Our vacuum-packed options extend shelf life by preventing oxidation of volatile compounds including thymoquinone.
