Black seed oil is as effective as Betamethasone, a skin cream, in treating hand eczema. What’s more, the side effects of Betamethasone is more frightening, for example, swelling, dark, freckles, etc.

Black seeds play a role in lowering blood sugar levels and cholesterol, both of which contribute to diabetes. Therefore, it is safe to say that black seed oil may help manage this medical condition.

Black Seed Oil Side Effects

Black seed oil does have amazing benefits for health; however, we must be aware of its potential side effects.

#1. Allergies

Topical application of black seed oil can cause contact dermatitis in some individuals, which means rashes, blotching, and itching. Therefore, you should perform a patch test before applying black cumin seeds on your skin. If you have any allergic symptoms, discontinue using the seeds and visit a doctor immediately.

It is likely unsafe for women to consume a large amount of black seed oil during pregnancy or breastfeeding period. The substance may slow down or even stop the uterus from contracting, leading to dangerous consequences.

Although there are no clear findings of this negative side effect of black cumin oil, it would be better to play safe and leave it alone.

#3. Blood Disorders

Anyone with blood disorders should stay away from black seed oil, or else there would be some severe consequences. For your concern, the oil may lead to slow blood clotting and excessive bleeding. If you are about to undergo surgery, it is advised to stop using black seed oil at least two weeks before the date.
