A Black Seed Oil Farmer We're Proud to Partner With


At Onhava, we have several criteria that a farmer must meet before we’ll partner with them.

They must share our passion for treating people well and caring for the environment.

They must have a high commitment to producing a naturally grown, organic harvest.

They must value honesty, integrity, and transparency… and embrace those values at every level in their farming operation. 

When we found Mr. Ewald Stipaler and his farm — Stork’s Nest — it became clear very quickly that he was a good match for us… and for our customers.



Traditional Wisdom Combined with Modern Know-How


Ewald Stipaler considers being a farmer his calling. He knew from a very young age that farming was his passion.

In college, he studied agriculture, making plant production and soil science his area of focus. There, he learned a technical understanding of biodiversity and ecology. He went on to work for twenty years as an environmental engineer.

Then, he took his extensive knowledge and experience and combined it with a passion for growing organic medicinal plants. 

Stork’s Nest is the result.

You Can Visit Any Time


In keeping with a philosophy of sustainability and transparency, Stork’s Nest is open to visitors. Ewald loves to get to know his customers, to show them around the farm so they can see the operation in action, and to share his love and passion for the land and for the organic crops he grows.

You can learn more about Stork’s Nest and Ewald’s philosophy here.

Ewald's scientific background, his ethics, and his commitment to purity, effectiveness, and safety can be readily seen on his site or during a visit to his farm.

While it’s easy to take Ewald’s word regarding the purity and potency of the black seed oil he produces, our commitment to you is that all of our products undergo third-party testing. We provide you the results to review before you make your purchase.

Because Stork's Nest is a small-scale farm, the variance in potency and purity of any batch of oil is low. We run two random tests on each batch — a result that is representative of the whole. This can only be done with small-scale farms since the batch can be readily isolated.

When you buy from a supplier that sources their seeds from many farms, it’s nearly impossible to get a consistent level of purity, effectiveness, and safety in each bottle because every batch may vary greatly in potency. We sidestep that problem by working with small-scale farmers. With our Black Seed Oil, sourced from Stork’s Nest farms, you always know exactly what you’re getting and have confidence that it can effectively support your overall health.

The Ancient Healing Remedy That Restores a Healthy Balance to Your Body’s Most Critical Systems


Onhava Naturals Black Seed Oil


For more than 3000 years healers in India, Egypt, and throughout the Middle East have turned to black seed and black seed oil as one of nature’s miracles


Ancient civilizations held this herb in high regard.

Archaeologists found black seed oil in Tutankhamun’s tomb…

Nefertiti used black seed oil as part of her skin regimen…

The Romans used black seed oil as a nutritional supplement….

The Greek physician Dioscorides praised black seed oil for its healing properties...

And sacred Muslim texts held black seed above all other herbs for its power and potency…


Now, please don’t take these statements as scientific proof of anything. Black seed oil doesn’t have magical properties as many ancient cultures believed — and it isn’t a cure for the common cold as some ancient physicians thought — but it is reasonable to ask…

What is it that has led this herb to be held in such reverence for thousands of years?

Well, it turns out that modern research shows black seed oil does have many compounds that provide natural support to some of your body’s most critical systems 


The Delicate Dance of Inflammation

Your body is an amazing, complex organism with countless responses built in to protect you from threats… environmental toxins, stress, viruses, fungi, parasites, bacteria…

When your body senses an invader or a threat, it produces an inflammatory response. You’ve probably heard that inflammation is bad. And in certain circumstances it can be. But a healthy inflammatory response is good! Life-saving, even. Your body’s natural inflammatory response helps fight off infection and is part of your body’s method for healing itself when an injury occurs.

However, if inflammation runs out of control or doesn’t stop when the threat has passed, bad things start to happen. Chronic low-grade inflammation undermines the effectiveness of your immune system and can damage and age your cells. As you get older, it gets harder and harder for your body to regulate its natural inflammation response. Often the result is chronic inflammation, the kind that attacks cells and makes it harder for your immune system to mount an attack when it needs to. This breakdown in inflammatory response puts your body at risk in many ways.

But there are bio-active compounds that can help your body’s immune system and inflammatory response function in a more balanced way.

Black Seed Oil’s Surprisingly High Number of Nutrients

Black seed oil contains a dizzying number of bioactive compounds. It contains proteins, essential fatty acids, carbohydrates, and fiber. It delivers a variety of amino acids… glutamate, arginine, aspartate, cysteine and methionine. On the list of vitamin and minerals iron, copper, zinc, phosphorus, calcium, thiamin, niacin, pyridoxine, and folic acid all show up. It also contains hundreds of phytoconstituents, many of which are still being analyzed by scientists.[1]

Because it has some many compounds that scientists want to understand better, researchers have begun to do studies on black seed oil…

And the results are promising.

 A Healthier Immune System

Now, first, it’s important to understand that the research on black seed oil is in its early stages. Studies so far have been small, but most researchers conclude that black seed oil has exciting potential and that bigger studies are warrented.

So what have researchers found so far?

Most research has focused on how black seed works with the body to promote a balanced inflammatory response. In one small-scale study researchers examined how black seed oil affected certain markers of inflammation. The study was double-blind, randomized, and placebo controlled. It lasted for eight weeks. At the end the researchers concluded that black seed oil showed great potential for lowering inflammation and oxidative stress.[1]

Another similar study found that when combined with a calorie-restricted diet, black seed oil helped lower key inflammation factors in the blood of participants by up 54% from levels before the study began, compared with a 21% reduction in the control group who also followed a calorie-restricted diet.[2] This study was also double-blind, randomized, and placebo controlled.

A third study yielded similar results.[3]

Each of these studies has been small — fewer than 100 participants — and has focused on people with conditions that tend to aggravate inflammation.

More research does need to be done, but the early results suggest that black seed oil can help your body maintain a healthy inflammation response… And when that happens your immune system will function closer to optimum. Which means a healthier you!

A New Source of Omega Fatty Acids

As someone who cares about your health and where your natural supplements come from, you almost certainly know the value of essential fatty acids to your heart, your brain, and your overall sense of well-being. And your immune system, too!

Black seed oil is a rich source of omega-3, omega-6, and omega-9 essential fatty acids. In our black seed oil, you’ll find these essential fatty acids in an optimal balance — 1:2:1.

This balance of essential fatty acids helps your body to work at its best on every level.

More Energy… Brighter Skin… Fewer Sick Days

Black seed oil is versatile. And it’s safe.

You can take it as a nutritional supplement. Most people who use it this way choose to mix a teaspoon of black seed oil along with a spoonful of honey into their favorite tea. When you drink this tonic every day, you’ll support your immune system by helping it better manage inflammation. A stronger immune system can mean more energy and fewer sick days. Plus, your body will be better able to protect again the everyday damage done by stress, poor diet choices, environmental toxins, and aging.

You can also use black seed oil topically on your skin and hair. It’s restorative properties can give your skin a glowing, more even appearance.[1] (When using any topical skin cream, it’s important to do a small test first to make sure it’s well-tolerated by your skin.)

Another topical use for black seed oil is as an additive to your favorite massage oil. Massaging sore muscles and joints is a good way to relieve aches and pains. Adding black seed oil can enhance the experience.

When you introduce black seed oil into your daily health routine, you will look and feel better, inside and out.

Q&A When Buying Black Seed Oil

Before buying black seed oil, make sure you ask these questions first to ensure you’re getting a product that is safe and effective.


So you’ve made the decision to buy black seed oil. You know the benefits to your immune system and the support that black seed oil provides to many critical systems within your body.

The next step is to figure out which brand of black seed oil to buy. It’s tempting to just look for the best-priced brand with the most four-star reviews. Reviews can be helpful, for sure. But your health situation is unique, and so the simple number of good reviews doesn’t necessarily mean anything in terms of your own circumstances and goals. If everyone loves a brand of black seed oil because they like the way their hair feels when they mix it with their shampoo, but you’re looking for something to support your immune system … well, those reviews aren’t very helpful. Even well-written, well-thought-out reviews can be hard to trust. Some people evaluate black seed oils with a mild taste more favorably. Others are suspicious of any black seed oil that isn’t as pungent as they think it should be. These are subjective measures.

The one measure you can trust is an evaluation of potency by a third-party lab. And this is best done on a batch-by-batch basis… because potencies can change. No matter which supplement you’re buying, there are questions you should ask to make sure you’re getting what you think you are. You can find the questions we think you should ask and why they are important here.

But there are some specific questions you should ask about your black seed oil supplement before you buy…


Was it grown on a small-scale farm?


Because black seed oil is affected by the soil it grows in, you’ll get a better product when it’s sourced from a single, small-scale farm. This will reduce variances in the black seed oil potency. It also increases transparency and allows you to verify that the oil is ethically sourced.

There are many factors that affect the purity, taste, potency, and safety of black seed oil. Growing black cumin seed can be a temperamental business. The plant is not only affected by the soil, but also by the climate, the ecosystem, the seeds that were used, the type of pest/herb control (if any), and the type of fertilizer used. Small variances in these things can lead to changes in the potency of the oil.

Most black seed oil companies get their seeds or oil from many farms. This maximizes their supply and profit. It takes a high volume of seeds to make the oil, and the machines that are used to clean the seeds are typically so large it’s common to mix many farms’ seeds together for the sake of economies of scale.

At Onhava Naturals, we put the quality of the product before profits. We don’t believe in telling you half-truths or making lofty claims that we can’t prove. For example, some companies indeed have a very potent oil and they might even publish the third-party testing results. But they will also intentionally leave out that their seeds contain harmful pesticides even though the region they buy from is known for it. Others simply hide behind the veil of legitimacy that official organic certification sometimes gives.


How were the seeds pressed?


Different seeds, treated in different ways, will lead to different results. Like other oils, the less heat used to extract the oil, the more likely it is that the purity and potency of the black seed oil and all of its bioactive components are preserved. It’s important to know the details of the pressing process including what type of machine was used to extract the oil, if any chemicals were used, and the skill of the machine operator.  


Where was your black seed oil grown?


Black seed oil can be grown around the world. It’s native to the Middle East and nearby regions like India and Eastern Europe. The region it grows in can affect its taste, its appearance, and its potency. Whatever supplier you choose, they should be open about the region your black seed oil comes from.


How is your black seed oil packaged?


Exposure to light can reduce your black seed oil’s potency. Choose a product that is packaged in an amber-colored glass bottle.


Has it been third-party tested?


The only way to know with confidence the purity and potency of your black seed oil is to review the results provided by a third-party testing lab. The company you purchase from should readily provide those results. This is important because some companies go to great lengths to increase their profits at your expense.

One popular practice is to mix one kind of oil with other cheaper oils. This deceptive practice has been exposed in highly publicized raids of the Italian olive oil industry, for example. And it can happen with black seed oil, too.

We have lab tested many brands of black seed oil (19 and counting) and unfortunately have encountered two (so far) that were mixed with other types of oils. Sadly, they have many positive reviews, which might be fraudulent.


What is its essential fatty acid count?


The label on your black seed oil should clearly show how much omega-3, omega-6, and omega-9 fatty acids are in a serving.
