Trends
Two years ago, 2,900 people a month searched for "oil of oregano with black seed oil" in the US. As of July 2026 it is 40,500, up 1,297% over two years. Every result on the first page of Google is somewhere to buy it.
Two things in our data complicate that picture. The term peaked at 90,500 in January 2026 and has fallen every quarter since, down 55% over six months. And one brand name, which barely existed a year ago, now draws 22,200 searches a month on its own, up 12,959%. This is not a category discovering an ingredient. It is a category being advertised into existence, and it has already passed its high point.
Key takeaways:
- "oil of oregano with black seed oil" went from 2,900 to 40,500 US monthly searches in two years, up 1,297%, but only 22% year over year (Rising Trends database, data as of July 2026).
- The peak was 90,500 in January 2026. It is now down 55% over six months.
- One brand term is up 12,959% year over year to 22,200 searches, more than half the size of the generic phrase.
- The NIH's LiverTox entry on oregano says its antimicrobial and antioxidant activities "have not been demonstrated in humans, and the clinical significance of these actions has not been established."
- On black seed, the same database says "the overall evidence for clinical benefit of these effects is not very convincing," and neither ingredient is approved by the FDA to treat any condition.
- The safety line nobody repeats: oregano at supplement doses "is an abortifacient and should not be used during pregnancy."
Let's get into it. This is a report on what the search data and the published evidence show. It is not medical advice, and nothing here is a recommendation to take or avoid anything. Supplements interact with medications, so a pharmacist or doctor is the right person to ask about your own situation.
The curve
Here is the monthly volume from our database.
The climb through 2025 is real: 3,600 in late 2024 to a steady 33,100 by mid-2025. Then December 2025 at 49,500 and January 2026 at 90,500, which is the peak.
January is the giveaway. Seasonality on this term is classified HIGH, and new-year resolution season is when supplement searches always spike. What happened next is the part worth watching: 60,500 in February, 60,500 in March, 49,500 in April and May, 40,500 in June and July. Six consecutive months of decline, and the term is now up only 22% year over year against 1,297% over two.
The category around it is falling faster.
oregano oil on its own draws 60,500 a month as of July 2026 and is down 18% over two years. gut health supplement is 18,100 and down 55% in a year. "immunity supplements" is 2,400 and down 56%.
So the combination term is growing inside a shrinking neighbourhood. The question is what is pulling it up, and the growth chart answers that plainly.
One brand term, up 12,959% in a year to 22,200 searches a month. That is 589 times the growth rate of the generic phrase it sits inside. A branded query that large, arriving that fast, in a category where everything else is flat or falling, is what a well-funded creator marketing campaign looks like when you measure it in search.
Here is the other tell. "carvacrol supplement" and "nigella sativa supplement", the actual names of the active compounds, draw 140 searches a month each. Nobody is researching the chemistry. They are searching the phrase from the advert.
What the NIH actually says
This is the part missing from every page currently ranking for the term, because every page currently ranking for the term is selling something.
LiverTox is the National Institutes of Health database on supplements and drugs. Its entry on oregano is one sentence long on the question everyone is actually asking:
Oregano "has antimicrobial, antifungal, antiparasitic, antioxidant, and antineoplastic activities in vitro and in vivo, but these effects have not been demonstrated in humans, and the clinical significance of these actions has not been established."
In vitro means in a dish. In vivo here means in animals. The gap between that and a person is where the entire marketing category lives.
The entry on black cumin, the plant sold as black seed, is slightly warmer and still not warm. Small placebo-controlled trials have found a slight decrease in LDL cholesterol, a modest effect on HbA1c in type 2 diabetes, and a modest effect on blood pressure. The NIH's summary of those results: "The overall evidence for clinical benefit of these effects, however, is not very convincing."
The scale of those trials is the reason. The blood-pressure study the database cites, for example, is a 2021 randomised trial of 60 adults in Iran, run for eight weeks against sunflower oil, in which 20% of the black cumin group reported mild gastrointestinal side effects. Sixty people for eight weeks is a signal worth following up. It is not a basis for a claim on a label.
And on both, the same bottom line. Oregano oil "has not been approved as therapy of any disease or medical condition in the United States." Neither black cumin extracts nor thymoquinone "have been approved as therapy for hyperlipidemia, diabetes, hypertension or any other medical disease or condition by the FDA."
| Oregano oil | Black seed oil | |
|---|---|---|
| Suspected active | Carvacrol or thymol | Thymoquinone |
| Evidence in humans | Effects not demonstrated | Not consistently demonstrated |
| FDA approved for any condition | No | No |
| Liver injury reported | None published | None published |
One more thing the NIH documents and no product page we checked mentions: oregano at supplement doses "is an abortifacient and should not be used during pregnancy or in women of childbearing age not using effective contraception." That is a direct quote, and it is the single most important sentence in this article.
Reported side effects at higher doses, again from the NIH: abdominal discomfort, heartburn, constipation or diarrhoea, nausea and vomiting, dizziness and headache for oregano; abdominal discomfort, bloating, altered taste, diarrhoea and headache for black seed. Both list rare hypersensitivity reactions. The oregano entry records a case of a man who had an immediate allergic reaction, including lip swelling and stridor, to foods containing oregano and thyme.
Where the searches are actually coming from
Search the term on Instagram and the pattern is immediate.
We chose this post deliberately, because it is the honest one. Its entire caption is five hashtags, and one of them is #ad. It is a disclosed advertisement, and it is representative of most of what is circulating under this term.
Others are less clear. A reel from May 2026 reads: "If you feel bloated after food this oregano and black seed oil softgels are for you. I feel the difference. Felt after 2-3 days," followed by two brand tags and "Link in bio." That is a health claim and a purchase path with no advertising label attached. We are quoting it as an example of the genre, not as evidence that the product does anything.
A whole review economy has grown up alongside it. Typical YouTube titles include "Legit Or Another Scam?" and "Does It Worth Or A Scam?", aimed at the competing brand Nutrivora. When the top organic content about a supplement is people asking whether it is a scam, the marketing has outrun the trust.
What it means for the supplements business
Stacking is the product innovation. Neither ingredient is new. Oregano has been in kitchens for millennia and black seed has a traditional claim on record so old the NIH quotes it: "the black cumin is healing for all diseases except death." What is new is putting two of them in one softgel and giving the combination a name. That is a marketing formulation, not a pharmacological one, and it is the same move running through the rest of the supplement category.
A brand can manufacture a category term. 12,959% growth on a branded query inside a flat category is the clearest example of this we have measured. It also means the category's health is hostage to one company's ad spend. If that budget stops, the generic term likely follows it down.
The synergy claim has no source. Marketing copy for these products often says carvacrol helps the body absorb thymoquinone. Neither NIH entry mentions it, and there is no trial of the combination. Anyone repeating that should say where it came from.
Scepticism is the growth content. The scam-check videos are outperforming the product content on the competing brand. That is where the audience is going once the ad has done its work, which is a familiar arc for anyone who followed the peptide market.
What to watch
Whether January 2027 beats January 2026. This term has HIGH seasonality and its peak was a new-year spike. If next January does not clear 90,500, the trend peaked in 2026 and the last two years were the whole story. The live trend page is where that resolves.
Whether the brand term keeps outgrowing the category. If "resilia oil of oregano with black seed oil" keeps climbing while the generic phrase falls, this was never a category at all. It was one company's funnel.
Whether regulators look at the claims. Structure and function claims on supplements are loosely policed until they are not. Unlabelled creator posts telling people a softgel fixes bloating in two to three days are the kind of thing that attracts attention, and the wider alternative medicine category has been through that cycle before.
The honest summary is that this is two old herbs, sold together, backed by laboratory results that nobody has reproduced in people, marketed hard enough to create 40,500 searches a month, and already declining. If you are going to take it anyway, the NIH's pregnancy warning is the part to read first.
