Fushi Black Seed Oil: An Honest Comparison

By Yusuf Elsayed, Founder of Sidr & Stone · Last updated 23 May 2026

Fushi black seed oil is one of the better-known organic black seed oils in the UK, and if you have been researching brands you have almost certainly come across it. This article is an honest comparison: what Fushi black seed oil is, what the brand states about it, how it compares with our own Sidr & Stone cold-pressed Ethiopian black seed oil, and — most importantly — the criteria that genuinely matter when you choose a black seed oil to buy. We compare only on facts each brand publishes on its own official website. The aim is not to talk down a competitor — Fushi is a credible brand — but to give you a clear, accurate basis for your own decision. An informed buyer is exactly the buyer we want.

The Short Answer

  • Fushi is an established UK natural-health brand; its Organic Black Seed Oil is Soil Association certified organic, cold-pressed, and unrefined
  • Fushi states its oil contains "up to 2.4%" thymoquinone — note the "up to" wording, and that Fushi describes the oil as non-standardised, with each batch varying
  • Fushi's current official website lists the seed origin as Turkey; some older third-party listings still show Egypt, which appears to reflect a past change in sourcing
  • Sidr & Stone uses Ethiopian highland seed and publishes a verified figure of 2.67% thymoquinone, independently tested per batch by an ISO-accredited laboratory
  • Both oils are genuine, organic-quality cold-pressed black seed oils — the meaningful differences are the thymoquinone figure and how it is verified
  • The single most useful thing any buyer can do is check whether a thymoquinone figure is a verified per-batch number or an "up to" ceiling claim

Who Is Fushi?

Fushi Wellbeing is a well-established UK natural-health and wellbeing brand, founded by Rannesh and Ria and rooted in an Ayurvedic family heritage. The name "Fushi" means eternal life. The brand sells a broad range of natural oils, supplements, and bodycare, with a stated emphasis on organic certification, purity, and environmentally conscious glass and aluminium packaging.

Its black seed oil — Fushi Organic Black Seed Oil — is sold in 100ml and 250ml sizes, and is widely stocked through Fushi's own website and a range of UK health retailers. Fushi markets it under its "Fresh-Pressed" branding, and it is one of the more visible organic black seed oils in the UK market. This is a credible, certified brand, and it deserves to be described as such.

What Fushi States About Its Oil

Working only from what Fushi publishes on its own official website, here is what the brand states about its black seed oil:

  • Extraction: Cold-pressed and unrefined, under Fushi's "Fresh-Pressed" branding. Hexane-free
  • Organic certification: Certified organic by the Soil Association (Licence No. DA223688) — a genuine, recognised certification
  • Thymoquinone: Fushi states the oil contains "up to 2.4%" thymoquinone, and describes this as around five times stronger than generic black seed oils at 0.5–1%
  • Standardisation: Fushi explicitly describes the oil as non-standardised, stating that each batch varies and shows its own characteristics
  • Seed origin: Fushi's current official website lists the origin as Turkey
  • Packaging: UV-protective glass

This is a respectable specification: organic-certified, cold-pressed, unrefined, in UV-protective glass. Fushi is doing a number of things right, and it would be dishonest to suggest otherwise. The two points worth examining more closely are the thymoquinone claim and the seed origin — which is where the comparison becomes genuinely useful.

The Comparison: Fushi and Sidr & Stone

Here is an honest, side-by-side look, based only on what each brand publishes officially. Both are genuine, organic-quality cold-pressed black seed oils; the differences are specific.

Cold-pressing and organic certification

Here the two brands are closely matched, and it is only fair to say so plainly. Both Fushi and Sidr & Stone are cold-pressed and unrefined. Both are organic. Both use UV-protective glass to guard the oil from light. On these baseline quality markers, the two oils are genuinely comparable, and Fushi clears them properly. Cold-pressing, organic status, and UV glass are not points of difference between us — they are a shared baseline.

Thymoquinone — "up to 2.4%" versus a verified 2.67%

This is the most important section of the comparison, and it turns on a small but decisive piece of wording.

Fushi states its oil contains "up to 2.4%" thymoquinone. Read carefully, "up to" is a ceiling, not a guarantee. It describes the highest figure a batch might reach — not a minimum, and not a fixed value. Fushi is also openly clear that the oil is non-standardised and that each batch varies. So a Fushi bottle might contain close to 2.4% thymoquinone, or it might contain less; the brand's own honest description does not promise a specific number in the bottle you receive.

To be fair to Fushi: stating "up to" and "non-standardised" is itself honest. It is far better than a brand inventing a flat figure it cannot stand behind. The point here is not that Fushi is being misleading — it is that an "up to" ceiling on a non-standardised oil is a fundamentally different kind of claim from a verified figure.

Sidr & Stone publishes a specific number: 2.67% thymoquinone, independently verified by an ISO-accredited laboratory (Analytice, in France), and tested batch by batch. This is not an "up to" ceiling — it is a measured figure, confirmed by an independent laboratory, with a Certificate of Analysis behind it.

So the honest comparison is this: Fushi's 2.4% is a ceiling on a non-standardised oil; Sidr & Stone's 2.67% is a verified, independently tested, per-batch figure. The two oils are both genuinely good cold-pressed organic black seed oils — but only one of them gives you, as an independently confirmed number, the thymoquinone content of the bottle in your hand. For anyone choosing a black seed oil seriously, that is the difference that should weigh most.

Seed origin

If you have researched Fushi, you may have noticed conflicting information about where its seed comes from — some pages say Egypt, others say Turkey. Here is the honest explanation: Fushi's current official website lists the seed origin as Turkey. Older third-party reseller listings still show Egypt. The most reasonable reading is that Fushi has changed its sourcing over time, and stale pages elsewhere on the web simply have not caught up. Both Egypt and Turkey are legitimate, traditional Nigella sativa growing regions, so this is not a criticism of Fushi — but it is worth knowing that the origin you read depends on how current the page is.

Sidr & Stone uses Nigella sativa seed from the Ethiopian highlands. We chose Ethiopian highland seed deliberately: in the comparative testing behind our 36-supplier evaluation, highland-grown Ethiopian seed consistently returned among the highest thymoquinone levels we measured. Seed origin directly influences how much thymoquinone the finished oil can contain — so it is a meaningful choice, not a cosmetic one.

Price

Both Fushi and Sidr & Stone sit in the genuine-quality, organic tier rather than the bargain-basement end of the market — neither is competing to be the cheapest black seed oil, and prices for both vary by size and retailer. Sidr & Stone is £25.99 for 100ml.

We will be straightforward: we are not asking you to choose Sidr & Stone because it is the cheapest. We are asking you to choose it because of what it lets you verify. The price reflects Ethiopian highland seed selected from a 36-supplier evaluation, independent per-batch laboratory testing with a published thymoquinone figure, UV-protective matte black glass, halal certification, and 10% of profits given to charity. A buyer should weigh price alongside verification — not on its own.

The Criteria That Actually Matter

Stepping back from any single brand, these are the criteria worth applying to any black seed oil — Fushi, Sidr & Stone, or another:

  • A thymoquinone figure — and how it is framed. The single most useful number. Look closely at whether it is a verified, measured figure or an "up to" ceiling on a non-standardised oil. They are not the same claim
  • Independent, ideally per-batch testing. A brand's own description is one thing; an independent ISO-accredited laboratory testing each batch is far stronger. Look for a Certificate of Analysis
  • Cold-pressed and unrefined. Both Fushi and Sidr & Stone clear this. Heat and refining degrade thymoquinone
  • Organic certification. Both brands have it — a recognised, verifiable standard
  • Transparent, current seed origin. Check the brand's own current page, not a stale reseller listing
  • UV-protective dark glass. Both brands use it; it protects the oil from light degradation
  • Honest, measured language. Be cautious of any black seed oil — any brand — described as a medicinal cure for specific diseases. It is a food supplement, not a medicine

Apply these and you will quickly see that Fushi and Sidr & Stone are both genuine quality oils — and that the deciding factor between them is verification: an "up to" ceiling versus an independently confirmed per-batch figure.

An Honest Word on Health Claims

One note in the interest of being straight with you. The black seed oil category — across many brands, and in retailer product copy everywhere — is full of strong health and "medicinal" language. You will see black seed oil described as healing or treating all sorts of specific conditions.

Sidr & Stone does not make disease claims, and we would gently encourage you to be measured about any black seed oil marketed in strongly medicinal terms. Black seed oil is a food supplement. It has a long traditional history and a genuinely interesting body of research around thymoquinone, and it can be a worthwhile part of a healthy routine — but it is not a medicine and not a substitute for medical care. That principle is part of why we publish a verified thymoquinone figure rather than reaching for dramatic claims: a real, independently confirmed number is worth more than a big promise.

Why Sidr & Stone

If, having weighed the comparison, you are considering Sidr & Stone, here is what you are choosing — every point a verifiable fact:

  • Ethiopian highland seed — selected through a 36-supplier evaluation for consistently high thymoquinone
  • 2.67% thymoquinone — a specific, verified figure, not an "up to" ceiling
  • Independent per-batch testing — by Analytice, an ISO-accredited French laboratory, with a Certificate of Analysis
  • Cold-pressed below 40°C — protecting the heat-sensitive thymoquinone
  • Unrefined and organic — the natural oil, nothing stripped out
  • Matte black UV-protective glass — guarding the oil from light
  • Halal certified
  • 10% of profits to charity
  • £25.99 for 100ml, shipped across the UK

That is the basis on which we would ask for your custom: not a claim of being the only good oil — Fushi is a genuine brand — but the clearest, most independently verified picture of what is actually in the bottle.

Frequently Asked Questions

Is Fushi black seed oil good quality?

Yes — Fushi is a credible brand and its Organic Black Seed Oil is Soil Association certified organic, cold-pressed, unrefined, and bottled in UV-protective glass. It is a genuine quality oil. The main thing for a buyer to understand is that Fushi states "up to 2.4%" thymoquinone on a non-standardised oil, which is a ceiling claim rather than a verified per-batch figure.

How much thymoquinone is in Fushi black seed oil?

Fushi states its black seed oil contains "up to 2.4%" thymoquinone. The wording "up to" describes a ceiling, not a guaranteed minimum, and Fushi openly states the oil is non-standardised with each batch varying. By comparison, Sidr & Stone publishes a verified 2.67% thymoquinone figure, independently tested per batch by an ISO-accredited laboratory.

Where is Fushi black seed oil sourced from?

Fushi's current official website lists the seed origin as Turkey. Some older third-party reseller listings still show Egypt, which appears to reflect a past change in Fushi's sourcing rather than a contradiction. Both Egypt and Turkey are traditional Nigella sativa regions. Sidr & Stone uses Ethiopian highland seed, chosen because it tested consistently high in thymoquinone in our supplier evaluation.

What does "up to 2.4% thymoquinone" mean?

"Up to" describes a maximum a batch might reach — it is a ceiling, not a guaranteed figure. Combined with Fushi's own statement that the oil is non-standardised and varies batch to batch, it means a given bottle may contain close to 2.4% thymoquinone or somewhat less. This is honest labelling by Fushi, but it is a different kind of claim from an independently verified, per-batch measured figure such as Sidr & Stone's 2.67%.

Is Fushi or Sidr & Stone black seed oil better?

Both are genuine, organic-certified, cold-pressed, unrefined black seed oils, and on those baseline markers they are closely matched. The deciding difference is verification: Fushi states "up to 2.4%" thymoquinone on a non-standardised oil, while Sidr & Stone publishes an independently verified, per-batch 2.67% figure with a Certificate of Analysis. If verified, confirmed potency matters most to you, Sidr & Stone is the stronger choice.

Is Fushi black seed oil cold-pressed?

Yes — Fushi states its black seed oil is cold-pressed and unrefined, under its "Fresh-Pressed" branding, and hexane-free. Sidr & Stone is likewise cold-pressed (below 40°C) and unrefined. Cold-pressing protects the heat-sensitive thymoquinone, and both brands do this properly.

What should I look for when buying black seed oil?

Look at how the thymoquinone figure is framed — a verified per-batch number is stronger than an "up to" ceiling. Look for independent, ideally per-batch laboratory testing with a Certificate of Analysis, cold-pressed and unrefined extraction, organic certification, transparent and current seed origin, UV-protective dark glass, and honest, measured language rather than disease claims.

Is black seed oil a medicine?

No. Black seed oil is a food supplement, not a medicine. It has a long traditional history and an interesting body of research around its main compound, thymoquinone, and can be a worthwhile part of a healthy routine — but it does not cure diseases and is not a substitute for medical care. Be cautious of any brand marketing black seed oil with specific disease-cure claims.

Final Thoughts

Fushi black seed oil is a genuine, credible product from a well-established UK organic brand. It is Soil Association certified, cold-pressed, unrefined, and bottled in UV-protective glass — a real quality oil, and we are happy to say so plainly. If you choose Fushi, you are not choosing a bad oil.

But an honest comparison comes down to what you can actually verify. Both Fushi and Sidr & Stone are organic, cold-pressed, and unrefined — genuinely matched there. Where they part company is the thymoquinone claim. Fushi states "up to 2.4%" on an oil it openly describes as non-standardised and batch-varying — honest labelling, but a ceiling rather than a guarantee. Sidr & Stone publishes a verified 2.67% figure, independently tested batch by batch by an ISO-accredited laboratory, with a Certificate of Analysis. One is a ceiling on a variable oil; the other is a confirmed number for the bottle you actually receive. That distinction is the heart of the comparison.

So choose on what matters to you. If you want a certified-organic cold-pressed oil and an "up to" potency figure is enough, Fushi is a sound choice. If you want to know — as an independently verified, per-batch number — exactly how much thymoquinone you are buying, Sidr & Stone is, on the published facts, the clearer and stronger choice. Either way, decide on verifiable facts rather than on marketing language.

Our cold-pressed Ethiopian black seed oil — independently verified at 2.67% thymoquinone — is available now, shipped across the UK.
