As a supplement, black seed oil can be ingested in pill or liquid form. The oil can also be used topically on skin and hair.
If buying the liquid form of black seed oil, it’s recommended to choose a high quality product that doesn’t have any added ingredients.
Furthermore, as supplements aren’t tested for their safety and effectiveness by the Food and Drug Administration (FDA), it’s important to choose a reputable brand.
Black seed oil has a strong flavor that’s slightly bitter and spicy. It’s often compared to cumin or oregano. As a result, if consuming black seed oil as a liquid, you may want to mix it with another strongly flavored ingredient, such as honey or lemon juice.
For topical uses, black seed oil can be massaged onto the skin.
