Black Seed Oil COA & TQ Documentation
Thymoquinone is the number that matters in black seed oil, and it is the number most brands leave vague. ThymoCura® measures it through independent laboratory analysis and records the result on the Certificate of Analysis for the applicable production batch — a documented figure tied to a real production run, not an adjective on a label.
ThymoCura Standard Black Seed Oil
Document ID: TC-65397 · Revision 1.0 · Issued 20 Sep 2026
Manufacturer-issued batch COA summary based on third-party laboratory analysis maintained in our quality records. It reports the measured thymoquinone result (UPC²) and the fatty-acid profile for the referenced production sample. Thymoquinone varies by batch, so this document describes that batch — it is not a specification for every bottle or future batch.

Thymoquinone: The Measured Number
Thymoquinone — usually shortened to TQ — is the characteristic compound of Nigella sativa and the single most useful figure for comparing one black seed oil against another. Most of the market describes it in language that cannot be checked: “premium,” “high potency,” or the particularly slippery “up to X%.”
ThymoCura® treats TQ as a measurement rather than a marketing adjective. It is quantified by independent laboratory analysis and the result is written on the Certificate of Analysis for the production batch it came from. The analytical method used is stated on that COA.
What we deliberately do not do is print one TQ percentage and present it as a permanent product specification. Black seed oil is a whole pressed oil, not a standardized extract, so its thymoquinone content moves with the seed harvest, the growing season, and the pressing run. A brand that promises an identical number on every bottle of a cold-pressed oil is either processing it beyond a simple press or not measuring each run. The honest version is batch documentation: measure the batch, document the batch’s own result.

What Is a Certificate of Analysis?
A Certificate of Analysis (COA) is a document issued by a laboratory recording the measured results for a specific production batch. It is the difference between a claim and a record: the COA states what was tested, on which batch, and what the instrument returned.
Testing carried out by an independent laboratory carries more weight than testing done in-house, because the laboratory has no commercial stake in the outcome. It reports what it finds. ThymoCura® uses accredited laboratories that follow recognized testing methodologies for botanical oils.
A COA is also specific in a way that a “lab tested” badge is not. That badge frequently refers to a single historical test, a different production lot, or the brand’s own internal testing. Asking which batch a certificate covers is the fastest way to tell documentation from decoration.
Why Batch-Specific Documentation Matters
Because thymoquinone genuinely varies between production runs, a certificate is only informative if it belongs to the run you are actually holding. A result from a lot pressed two seasons ago tells you about that lot.
When you order ThymoCura® black seed oil, the COA corresponds to your bottle’s own production batch. That is also why we do not advertise a single archived figure as though it described the product in general — doing so would recreate exactly the fixed-number problem that batch documentation exists to solve.
Additional Laboratory Documentation
Depending on the production batch, additional laboratory documentation may be available for parameters such as fatty acid profile, heavy metals, microbiological quality, peroxide value or other quality indicators. Testing scope varies by batch, so rather than assuming a fixed panel, ask us which documentation is on file for the batch you are buying — and expect the same answer from any supplier making broader claims.
Why Independent Testing Matters
Quality varies widely in the black seed oil market. Some oils are cut with cheaper carrier oils, some are extracted with chemical solvents, and some are pressed from seed of inconsistent quality. Without independent measurement there is no reliable way to tell any of that from the bottle.
Independent analysis closes that gap for the parameter that matters most. Our cold-pressed extraction process uses no heat and no chemical solvents, which helps preserve the oil’s natural profile; laboratory analysis then documents the thymoquinone result of that process for the batch in question.
Request COA Documentation
COA documentation is available on request and is issued per production batch, so what you receive matches the actual batch in your bottle rather than a generic sample certificate.
- Reach us through our contact form with your order number or order date
- We match your request to the COA for your order’s production batch
- Wholesale and private-label buyers receive batch documentation with their shipment
Request Available Lab Documentation
Tell us the product and size you bought, or the batch you are evaluating as a wholesale buyer, and we will send the Certificate of Analysis on file for that production batch along with any further laboratory documentation available for it.
The current published batch COA summary (TC-65397) is available at the top of this page. Documentation for other production batches is supplied directly to customers and qualified partners.
