Black seed oil comes from seeds of Nigella sativa, which grow in Western Asia and Eastern Europe. Also known as black caraway, black cumin and kalonji, these seeds have long been used in herbal medicine.
Talk to your doctor before trying black seed oil, especially if you have diabetes or low blood pressure. It may lower blood sugar and interfere with some medications.
Anti-Inflammatory Properties
Black seed oil contains compounds that reduce inflammation throughout the body, including in the brain. It is also believed to help prevent dementia and Parkinson’s disease.
Intake of black seed oil has been shown to alleviate symptoms of rheumatoid arthritis, such as swollen joints and morning stiffness. It may also help to relieve gastrointestinal distress.
Ingestion of black seed oil is LIKELY SAFE in small amounts when used as a flavoring in food. However, it is not safe for people who have a sensitive skin and may cause allergic-type rash when applied topically to the skin. It may also interact with medications, such as blood thinners, ACE inhibitors and some antibiotics.
Anti-Cancer Properties
Black seed oil (nigella sativa) is often promoted as a natural cure for cancer, hair loss, acne and other health issues. However, there is not enough scientific evidence of these claims.
Thymoquinone in black seed oil promotes apoptosis and reduces the growth of tumors in human pancreatic cancer cells. It also promotes normal cell proliferation and suppresses inflammatory pathways that contribute to cancer cell growth.
Taking 2.5 milliliters of black seed oil twice daily reduces total and “bad” low-density lipoprotein cholesterol levels in people with high blood pressure. It also relieves symptoms associated with opiate withdrawal. It may help lower liver enzymes and improve symptoms of oxidative stress, such as indigestion, abdominal distention, bloating and vomiting.
Anti-Heart Disease Properties
Research shows black seed oil protects the liver and helps it process toxins. It also reduces oxidative stress on the organ, which can help protect against conditions like hepatitis, cirrhosis and Tylenol liver damage.
In a small 2015 study, women with type 2 diabetes who took 3 grams of black seed oil daily saw lower levels of LDL cholesterol and triglycerides than women in the placebo group. However, more research is needed to confirm these results. Talk to your doctor before trying any new supplement, including black seed oil. Your doctor can recommend the correct dose and monitor any side effects you might experience.
Anti-Infective Properties
Black seed oil has anti-bacterial, anti-inflammatory and anticancer properties that can improve the healing process of many skin conditions, including psoriasis, eczema and vitiligo, says dermatologist Azadeh Shirazi. It can also help reduce symptoms of chronic illnesses like diabetes and liver-related issues.
It’s important to speak with your doctor before trying any natural remedies. Black seed oil can interact with diabetes medications and may lower blood sugar levels, and it can interfere with medicines that prevent blood clotting or increase bleeding risk.
Be sure to choose a high-quality black seed oil that is 100 percent pure, therapeutic grade and USDA-certified organic. It should be free of solvents, pesticides and gluten.
Anti-Vitiligo Properties
Black seed oil benefits the skin in many ways. It has been found to be effective in reducing pigmentation either caused by inflammation or injury (melasma) and even to help those who suffer from skin loss (vitiligo).
In one study, people with vitiligo applied a cream containing black seed oil twice a day for six months. This resulted in a significant improvement in the pigmentation of their hands, face and genital region.
The black seed is LIKELY SAFE for most adults when taken in small amounts as a food flavoring or supplement, but there’s not enough information to know if it is safe for pregnant women and breastfeeding mothers. It is also not recommended for those who have a bleeding disorder or are taking blood thinners.
Anti-Acne Properties
Nigella sativa oil has been used for thousands of years as a natural remedy. Ayurvedic doctors hail it as a strength-enhancing, digestion-improving and skin-treating substance.
Black seed oil benefits include anti-inflammatory, antibacterial and antioxidant properties that promote wound healing. It also has liver- and kidney-protective qualities.
Thymoquinone in black seed oil can help treat vitiligo, a disorder that causes pigment loss in patches on the skin. In one study, topical application of a black seed oil cream resulted in statistically significant repigmentation in participants with the condition. However, further studies are needed. As with any dietary supplement, consult your doctor before adding black seed oil to your diet.
