Research indicates that black seed, known for its anti-inflammatory and antibacterial properties, could potentially help manage conditions such as psoriasis, asthma, hair loss, and acne. However, more human studies are necessary to confirm these potential benefits.
Black seed oil is derived from Nigella sativa, a plant native to Eastern Europe and Western Asia. Its medicinal properties are attributed primarily to its rich content of antioxidants and bioactive compounds. Below are some of the potential health benefits of black seed.
May Reduce Acne
Some studies suggest that black seed oil, when applied externally, may help improve skin conditions like acne due to its antimicrobial and anti-inflammatory effects.
For instance, a 2020 study found that applying a topical gel made from black seed extract twice daily for 60 days reduced acne severity by 78%. Participants in the study also experienced a significant reduction in the number of acne lesions compared to a control group.
Could Help Treat Psoriasis
Although more human studies are required, research shows that Nigella sativa extract possesses anti-inflammatory benefits, with animal studies suggesting that black seed oil can reduce skin inflammation and other symptoms associated with psoriasis.
A 2017 review also indicated that combining oral and topical forms of black seed extract reduced symptoms and improved skin lesions in psoriasis patients.
Promotes Wound Healing
Black seed oil contains thymoquinone, a compound that may stimulate tissue growth and aid in wound healing when applied to the skin.
The 2017 review mentioned earlier found that thymoquinone’s anti-inflammatory, antioxidant, and antibacterial properties might help treat burns, cuts, and other wounds by increasing collagen production and moisturizing the skin—factors beneficial for healing.
May Support Hair Health and Growth
Black seed extract is often added to hair care products due to its potential to enhance hair health. A 2020 review highlighted a study in which daily use of a Nigella sativa lotion for three months significantly improved hair density and thickness in individuals with telogen effluvium, a common form of hair loss.
Another study involving 90 participants found that black seed oil was the most effective in reducing hair loss among various seed oils tested.
May Protect Lung Health and Reduce Asthma Attacks
Black seed oil may benefit individuals with asthma. A 2020 review cited a small study in which inhaling boiled black seed extract improved markers of lung function and respiratory rate in asthma patients.
Furthermore, a 2021 meta-analysis of four randomized controlled trials found that black seed supplements might help manage asthma through their anti-inflammatory effects. However, further clinical data is needed to confirm its potential benefits for lung health.
Could Aid in the Treatment of Vitiligo
Some research suggests that black seed oil may help treat vitiligo, a condition that causes skin pigmentation loss.
One study involving 33 people with vitiligo found that applying a black seed oil cream twice daily for six months improved pigmentation in the hands, face, and genital areas.
Researchers believe the oil’s benefits may stem from its ability to promote melanin spread within the skin, but further studies are needed.
Reduces Local and Systemic Inflammation
Studies have demonstrated black seed oil’s powerful anti-inflammatory properties, which could positively impact health.
Inflammation plays a role in developing chronic conditions such as type 2 diabetes, heart disease, and cancer, so black seed oil’s anti-inflammatory effects may offer protective benefits against these diseases.
May Support Weight Loss
A study involving 45 women with overweight or obesity found that taking 2,000 mg of black seed oil daily for eight weeks reduced appetite and lowered body mass index, body weight, waist circumference, and body fat.
However, the long-term use of black seed oil requires more research, and caution is advised when using supplements for extended periods.
Improves Blood Sugar Levels
Black seed oil may help stabilize blood sugar levels. A 2019 review found that black seed improved various markers, such as insulin and blood sugar levels, during fasting and after meals.
Could Reduce the Risk of Metabolic Syndrome
Black seed oil might reduce the risk of metabolic syndrome, a cluster of conditions that increase the likelihood of heart disease, stroke, and type 2 diabetes.
A clinical trial involving 55 participants with high blood pressure showed that taking 2.5 mL of black seed oil twice daily for eight weeks improved diastolic blood pressure, cholesterol levels, and fasting blood sugar.
Nevertheless, a well-rounded diet and active lifestyle remain the best preventive measures against metabolic syndrome. It’s essential to consult a healthcare professional to ensure supplements like black seed oil are suitable for your individual health needs.
Frequently Asked Questions
Is it OK to take black seed oil every day?
Black seed oil appears to be safe in small amounts, such as when used in cooking or as a supplement for less than three months.
However, more research is needed to determine its safety in larger quantities or for prolonged use. Always consult a doctor before taking any supplement, particularly if you are pregnant or have underlying health conditions.
Does black seed oil grow hair?
Black seed oil is commonly found in shampoos and hair masks due to its antimicrobial and antioxidant properties, which may support overall hair health. Some evidence suggests it may aid in hair loss related to inflammation or telogen effluvium.
