BIONATAL QUALITY
Do you have a better price for imported black seed oil?
Do you try to find the best quality black seed oil?
Then answer the following seven questions to make sure that you buy a high-quality product:
- Do you know the origin of the seeds used to extract the oil offered to you?
- Do you know the pureness level of the seeds used?
- Do you know the harvesting year of those seeds?
- Do you know how many times seeds were pressed to extract the oil?
- Do you know the pressing temperature?
- Is it filtered or non-filtered oil?
Before purchasing a product, you may ask yourself this last question:
DO YOU WANT TO BUY REAL BLACK SEED OIL OR JUST OIL?
BioNatal stands behind our products and we are the only company in the world for the handmade items we offer. We answer all those questions and provide proof to our customers.
Here we will explain the difference in quality and show you the link to a full set of documents that prove the high quality of BioNatal’s Nigella Sativa oil from Ethiopian black seeds:
1. The huge difference is in the place of origin. The article on the Black Seeds page on our website clearly shows a huge difference in nutrition after comparing material from different 12 Nigella Sativa black seed grower countries. Such big differences happen due to climate conditions, quality of soil, and quality of water.
Besides the 12 main grower countries, there are other countries with unsuitable conditions that grow black cumin seeds just for commercial purposes. That’s why almost all Nigella Sativa oils on the market have no mark about the seeds’ country of origin. Maybe the oil is extracted by all rules and conditions, but the seeds themselves are not rich in minerals, vitamins, or nutrients—even (and especially) if you can buy them real cheap.
Various research from 2004-2016 showed that the best seeds are grown in Ethiopia. However, not many factories deal with this African country due to its location. To tap into this resource, BioNatal was established specifically to bring the best and most rare products from specific regions to consumers in the USA. That’s why our black seed oil extracted and all other products are from real Ethiopian seeds.
Ethiopian seeds are the most nutritious when compared to other Nigella Sativa seeds from other countries. Ethiopian black seeds are more expensive due to the high quality. In addition, it is very difficult to work with Ethiopian farmers and logistic in this African country. Many producers may claim they use Ethiopian seeds when they don’t. In order to prove this is true, they need to provide an Ethiopian Certificate of Origin that may be provided to customers upon request. BioNatal uses the most expensive and greatest Ethiopian seeds and our Certificates are available for public view at our Certificates page.
Biggest companies worldwide extract oils from seeds of different countries with different quality. Most popular for oil extracting seeds from Egypt, Syria, and India. These seeds have shown not the worst results but definitely incomparable with Ethiopian. Different seeds from all main suppliers (Ethiopia, Egypt, Syria, and India) give a different kind of Nigella Sativa oil. Our customers always can view (on our Certificates page) the Certificates of Origin for our imported seeds from Ethiopia.

Difference of the most used black cumin seeds for oil extraction:
Black seed oil from Ethiopian seeds is black but may appear lighter in small doses
2. A very important factor in the quality of the oil is the pureness of the pressed black cumin seeds. After harvesting the seeds from the flowers, batches can contain a huge amount of dry flowers petals and dry stems, mud, and dust. Seeds supplier need to be careful in the selection process to maintain pureness of at least 98%. Many factories extract organic oils of lower quality (85-95%) because this waste isn’t filtered out properly.
BioNatal imports seeds with a 99% pureness rating (Sortex selection quality) and this fact is mentioned in the Certificate of Origin, which you can view on the Certificates page. In addition, we also show our seeds on the BLOG section of the website and our customers can also follow us on social networks (on Contacts page) and see the production process, starting with our raw materials.
3. Another very important factor that directly affects the quality of Nigella Sativa oil is the date of harvest. Before a new season begins in every country, the price of the previous season’s seeds go down. That’s a big opportunity to produce cheap oil for many Middle East factories. Subsequently, a large number of oils on the market are extracted from 1-2 year old seeds. This is a very dangerous practice as, after the first year of storage, mold can quickly grow.
BioNatal always uses fresh materials and, on the Certificates page, we upload a Phytosanitary Certificate of the exporter country to show the crop year

Just harvested black seeds from Ethiopia of Sortex pureness 99% for BioNatal in USA
4. Black seeds contain 30-32% of oil inside. One press gets about 20-25% of oil from the seeds. However, most factories press twice, thus reducing the price of the final product. Since the first press should be at a temperature of 104°F (+40°C), the seeds are burning by the time of the second press, which is why Benzopyrene and increased acid levels appear in twice pressed oils—degrading the quality.
The international acceptable standard presence of Benzopyrene in products is 2.0 BaP but all twice-pressed oils have a level from 5.0 to 10.5 BaP. The acid level is also high and some oils from Middle East producers reach 27.0 pH (compared to a quality black seed oil at 4.0 pH).
This is a very common problem for most Nigella Sativa oils. The final customer can never know this fact because even analyses and quality certificates show only good nutrition because they never check for burning components and acid levels. This is why BioNatal now presents to customers US analyses where oils are specially tested for Benzopyrene and acid levels as evidence that BioNatal organic oils are only pressed once. Analyses results can be found on the Certificates page.
5. The main way to reduce the price of manufacturing this product is to press hot seeds. Many factories use one-time press for natural oil extraction but never use cold press like we do. Cold press means pressing seeds with a maximum temperature of 104°F (+40°C).
This process is hard because the seeds are pressed slowly and it puts pressure on the equipment. The cold press method extracts 20-25% out of the 32% of oil available in the seeds. Many producers raise the pressing temperature of the seeds to 140°F - 194°F (+60-90°C) in order to work faster, get 25-30% of oil and reduce pressure on the pressing machine. This way, the producers solve the problem with the speed of production and are able to supply more, but they still have burned the materials and a high acid value will be present in the finished product. In addition, this hot method reduces most of the beneficial medical components inside the seeds.
BioNatal uses only cold pressing techniques and, therefore, we have an acceptable level of Benzopyrene and acid value. The US analyses demonstrating such are on the Certificates page

BioNatal's equipment extracts black seed oil with just 75-98°F (+24-37°C). Real COLD-PRESS!!!
6. The filtering process does not affect the cost of the Nigella Sativa oil. Almost all black seed oil producers worldwide filter the oil after the extraction process because people are used to buying filtered oil. BioNatal only offers non-filtered black seed oil since the rest of the seed part is considered sediment and contains vitamins and minerals. If you get rid of the sediment, the pure oil loses some important components and bitterness.
BioNatal does not filter the oil but cleans it, manually provide acceptable levels of sediment (5%). No other factory uses this method since this many stages process takes a few weeks and places a hold on sales and should be only handmade. We are patient since our target is to provide the best quality of black cumin seed oil to our customers.
The sedimentation period takes from 25 to 30 days. This means we keep the oil in 5 gallon-glass barrels between temperatures of 62-72°F.
7. The last stage is the “bottling process” which takes a place right after the sedimentation process. BioNatal produces just enough oil to keep up with orders as they are coming in. We currently press oil three times a week, and bottle three times a week. We ship fresh oil (right after the sedimentation process) ONLY.
Frequently asked questions:
- Which is better Glass or Plastic (PETE)?
BioNatal’s black seed oil is always fresh and there is no difference in the 16oz Glass or PETE bottle. PETE bottling containers do not contain BPA or Phthalates. It is safe to keep black seed oil in PETE bottles if the bottle is not exposed to the sun or will be sitting in the shelf for quite some time.
It is up to the consumer; some people prefer glass

• Use of commercial equipment (slow working speed gives low press temperature)
• Use of equipment for 3 hours a day ONLY (after 4 hours any equipment is heating the oil, so we end it early)
• Temperature log is being recorded every hour on all pressing machines (75 to 98F) (cold-press standard is 115F)
• Benzo(a)pyrene level is 0.95 ng/kg (this is the cold-press confirmation which should be less than 2.0 ng/kg)
