Nigella sativa is also known as black seed is the plant from which black seed oil is made. The oil is taken from its small black seeds and has been used in traditional medicine for many centuries. It is commonly found in South Asia, the Middle East, and parts of Eastern Europe. Black seed oil is popular because it contains a natural compound called thymoquinone, which has antioxidant and anti-inflammatory effects. People traditionally use it to support the immune system, improve digestion, and promote healthy skin and hair.
It is also sometimes used to help with allergies, asthma, and mild joint pain. Some research suggests that black seed oil may help manage blood sugar, cholesterol levels and heart health but more studies are needed to confirm these benefits. It is available in liquid and capsule forms and can be taken by mouth or applied to the skin. Although it is generally safe when used properly, taking too much may cause stomach upset or allergic reactions, so it’s best to speak with a healthcare professional before using it regularly, especially if you have health conditions or take other medicines.
