Benefits of black seed oil :
Cancer: Black seed oil is pressed from the seeds of a flowering shrub, Nigella sativa. The plant is packed with thymoquinone, a compound that may have cancer-fighting powers. In rats, it shrank tumors and slowed their growth as well as protected tissue from radiation damage. But we need more proof to know if it might help humans.
Fights Inflammation: Black seed oil has been in use for thousands of years for medicine, food, and even cosmetics. Today, many people reach for it for the same reason you’d take an aspirin or ibuprofen: In hopes that it targets inflammation and tamps it down. It also has substances that can help protect cells from damage.
Allergies: In one small study, people put black seed oil drops in their noses to treat mild, moderate, or severe cases of allergic rhinitis, aka hay fever. After 6 weeks, more than 9 of 10 people said their sneezing, itchy eyes, stuffy nose, and other symptoms got better or went away completely. That was true for just 3 in 10 people in the group that used regular food oil. More research is needed. Ask your doctor if black seed oil is right for your condition.
Acne: If Cleopatra had pimples, she probably dabbed on black seed oil to clear them up. For centuries it’s been used to treat rashes, psoriasis, and skin inflammation. Studies suggest that black seed oil may work just as well as benzoyl for acne.
Heart Benefits: In many parts of the world, Nigella sativa seeds are used as traditional medicine for obesity, diabetes, and high blood pressure. In some small studies, supplements made with it have shown to lower levels of cholesterol and blood fats called triglycerides. Taking powdered (but not oil) supplement may even boost your “good” cholesterol when coupled with aerobic exercise.
In the Kitchen: The seeds from N. sativa go by the names black seeds, black cumin, black caraway, and kalonji. You can use them or their oil like cumin or oregano to spice curry dishes, pickles, and bread.
Asthma: This is when your airways swell up and make it hard to breathe. One well-designed but the small study found that black seed oil helped control asthma symptoms better than dummy treatments. Researchers think that someday, the oil could be added to regular asthma therapy.
Male Fertility: Studies with both infertile men and rats have found that black seed oil can boost sperm count and help sperm swim faster. Antioxidants in the oil likely help protect sperm from damage. But more clinical trials are needed to know if the oil can be a good treatment for male infertility.
