People have used black seed oil for its therapeutic benefits for thousands of years.
Studies suggest that this oil may offer many health and cosmetic benefits, such as aiding weight loss, improving skin conditions, and even treating cancer and diabetes.
In this article, we look at the science behind black seed oil’s benefits and explore the possible side effects and risks.

Black seeds are also known as black caraway, black cumin, kalonji, and black onion seeds.
They come from Nigella sativa, a small plant with pale purple, blue, or white flowers that grows in Eastern Europe, Western Asia, and the Middle East.
People have used the tiny black seeds of the fruits of N. sativa as a natural remedy for thousands of years. The seeds can also flavor curries, pickles, and bread in a similar way to cumin or oregano.
Black seed oil contains thymoquinone, which is an antioxidant and anti-inflammatory compound that may also have tumor-reducing properties.
People can ingest black seed oil in the form of capsules or apply it topically to benefit the skin. It is also possible to add the oil to massage oils, shampoos, homemade skin-care products, and fragrances.
High-quality black seed oil is also suitable for use in cooking, baking, and beverages.
Medical News Today analyzes how changes in temperature and precipitation over time have affected the epidemiology of West Nile virus.
Scientists with a range of specialties have researched the possible benefits of black seed oil.
However, it is important to note that many studies to date have used cells or animals as models, and there is limited research available on the effects of black seed oil in humans.
Benefits for weight loss
Research has shown that black seed supplementation can help lower people’s body mass index (BMI). The study participants did not report any severe side effects from taking this supplement.
A systematic review published in the Journal of Diabetes & Metabolic Disorders in 2013 found that black seed oil could be effective in tackling obesity.
Benefits for the skin
Black seed oil may be beneficial for people with the following skin conditions:
- Eczema: According to a small-scale 2013 study comparing the therapeutic benefits of N. sativa with those of prescription medications, black seed oil can reduce the severity of hand eczema.
- Acne: Research suggests that the antimicrobial and anti-inflammatory effects of black seed oil can improve acne. In one study, 58 percent of participants rated their response to this treatment as good, while 35 percent felt their results were moderate.
- Psoriasis: A 2012 study on mice suggests that the oil may also have antipsoriatic benefits.
Black seed oil may also hydrate hair, soften skin, and act as a moisturizer, although there is a lack of scientific evidence to confirm these benefits.
Benefits for health conditions
Black seed oil may also be beneficial for some health conditions, including the following:
Cancer
Recent studies have shown that the thymoquinone in black seed oil can influence programmed cell death, or apoptosis, in several types of cancer cell. These include brain cancer, leukemia, and breast cancer cells.
However, much of the research on the effects of black seed oil on cancer uses cells rather than live humans, so researchers do not yet know how effective the oil may be to treat people with cancer.
Liver and kidney function
According to a 2013 study on rats, black seed oil may reduce liver and kidney disease complications and improve the organ structures. Researchers do not know if these effects would also occur in humans.
Diabetes
According to an article in the Journal of Endocrinology & Metabolism, black seed oil may have antidiabetic properties and improve blood sugar levels. Again, this study used animal models, so more research is necessary to confirm the effectiveness of the oil in humans.
Infertility
A placebo-controlled clinical trial on men with abnormal sperm and infertility has found that black seed oil can improve sperm movement and increase sperm count and semen volume.

Although black seed oil seems to offer certain health benefits, this supplement does not replace medication.
People taking medication should talk to their doctor before using herbal supplements, such as black seed oil.
The doctor can advise on possible interactions with the medication and also discuss the potential benefits and side effects of the supplement. It is essential never to stop taking medication without a doctor’s advice.
As with any supplement, pregnant or breastfeeding women should talk to their doctor to see if black seed oil is right for them before using it.
With topical use, black seed oil can cause an allergic rash in some people. Therefore, it is vital to test it on a small patch of skin first to ensure that it does not trigger a reaction.
People must also take care to keep the oil away from the eyes, nostrils, and other sensitive body parts.
Swallowing black seed oil can sometimes lead to digestive problems, such as stomach upset, constipation, and vomiting.
To get the safest and most beneficial black seed oil, always choose high-quality, organic black seed oil that is 100-percent pure, therapeutic grade, and USDA certified.
People have used black seed oil for its therapeutic benefits for thousands of years.
Many studies have shown that it may have health and cosmetic benefits for various medical and skin conditions, although these studies often use animal or cell models rather than humans.
More research into the effects of N. sativa in humans is necessary to confirm its benefits.
Always talk to a doctor before taking black seed oil, and choose 100-percent pure, therapeutic-grade, USDA-certified organic black seed oil. The United States Food and Drug Administration (FDA) do not monitor herbs and supplements for quality and purity, so it is vital to be selective when purchasing these products.

What is black seed oil?
Nigella sativa is a small flowering shrub with purple or white-tinged flowers that grows in Eastern Europe, the Middle East, and western Asia.
While it may look unsuspecting, the shrub produces fruits that have tiny black seeds. These black seeds have been used in remedies for thousands of years.
Archaeologists even found black seeds in King Tut’s tomb, emphasizing their importance in history for healing and protection. They’re also used in cooking to add flavor to breads, curries, and pickles. When eaten, the seeds have a bitter flavor that’s often compared to cumin or oregano.
Some additional names for black seed oil include:
- black caraway
- black cumin
- black onion seed
- kalonji
Black seed oil has been shown to have antioxidant properties. These can help relieve inflammation inside the body and on the skin. Herbs and supplements are not monitored by the FDA. Research and use reputable brands.
Black seed oil has shown promise in treating some of the most common health conditions, including high blood pressure and asthma. It also shows strong antifungal activity against Candida albicans — yeast that can overgrow in the body and lead to candidiasis. Examples of other black seed oil health benefits include:
- Reducing high blood pressure: Taking black cumin seed extract for two months has been shown to reduce high blood pressure in people whose blood pressure is mildly elevated.
- Reducing high cholesterol: Taking black seed oil has been shown to reduce high cholesterol. It’s high in healthy fatty acids that can help you maintain healthier cholesterol levels. Examples of these fatty acids include linoleic acids and oleic acid. The levels of the oils can vary depending on where the black seeds are grown. People may also see results when consuming the crushed seeds.
- Improving rheumatoid arthritis symptoms: Taking oral black seed oil may help to reduce inflammatory rheumatoid arthritis symptoms.
- Decreasing asthma symptoms: The anti-inflammatory effects of black seed oil may extend to improving asthma symptoms. Its effect in reducing inflammation in the airways may also help with bronchitis symptoms.
- Reducing stomach upset: Eating black seeds or taking black seed oil is associated with relieving stomach pain and cramps. The oil can help to reduce gas, stomach bloating, and the incidence of ulcers as well.
Black seed oil is also thought to have anticancer properties. It may help fight against skin cancers when applied topically.
Portions of black seed oil known as thymoquinone and other seed potions were able to reduce the growth of tumors in lab rats. The oil also may help to reduce the tissue damaging effects of radiation that is used to kill cancer cells. But these results haven’t been studied in humans. Black seed oil shouldn’t be used as a substitute for conventional cancer treatments.
Black seed oil has several applications and benefits for problematic skin conditions. The oil is found in many health foods stores and pharmacies. Examples of applications for beauty and skin include:
- Acne: According to the Journal of Dermatology & Dermatologic Surgery, applying a lotion prepared with 10 percent black seed oil significantly reduced the incidence of acne after two months. Those who participated in the study reported 67 percent satisfaction.
- Hydrating hair: Black seed oil can be applied to human hair to soften it and promote shine.
- Psoriasis: Applying black seed oil has been shown to reduce the incidence of psoriasis plaques.
- Softening skin: Black seed oil has been added to oils and moisturizers to improve skin moisture and hydration.
- Wound healing: Application of black seed oil has been shown to reduce inflammation and the presence of bacteria to aid in wound healing. While it doesn’t seem to be helpful in growing new collagen fibers, it does stimulate other growth factors to help the body create new, healthy skin.
Remember, black seed oil shouldn’t replace prescription treatments that a doctor may give you. But it does have some beauty benefits that can work in addition to these treatments to enhance your skin.

It’s possible that black seed oil can increase the effects of medicines that the body processes through the cytochrome P450 pathway. Enzymes in this pathway metabolize 90 percent of common medications. Examples of common medications can include beta-blockers such as metoprolol (Lopressor) and the blood thinner warfarin (Coumadin).
If you take any prescription medications regularly, talk to your doctor before starting to take black seed oil. You shouldn’t stop taking any of your regular medications without talking to your doctor first.
Black seed oil can be helpful to liver function, but taking too much black seed oil can also be harmful to your liver and kidneys. If you have problems with either of these organs, talk to your doctor to determine a safe dose (if any). Also, topical black seed oil can cause allergic reactions. Do a patch test before applying it to a large area on your skin.
If you’re looking to expand your palate, you can incorporate black seeds into your dishes. Suggestions on foods to add black seeds to include:
- toasted and sprinkled on flatbreads like naan
- toasted and sprinkled over bagels or biscuits
- added to soups, curries, and stir-fries
- grinding them and mixing them with other seasonings like mustard, fennel, and cumin seeds
You can also purchase black seed oil at most health stores and pharmacies. The oil is often packaged into capsules for daily consumption. It’s also sold as an oil that can be applied to the skin and hair or taken by the spoonful.
