Studies undertaken on animals have revealed that use of black cumin possesses the ability to halt tumour cell growth and also reduce the cases of tumours. However, owing to the absence of studies on humans in this regard, their effect on humans is unknown. Animal studies with Nigella sativa have also shown that injecting the oil extracted from its seeds may possibly protect from tissue damages due to radiation. In this case too, the effects of the seed extract on humans are unknown as far as protection from radiation is concerned. Findings of one study undertaken on humans showed that using black cumin seed extract every day for a period of two months may help to reduce blood pressure in people enduring mild hypertension.

This species is widely cultivated in India and a number of countries in West Asia for its edible seeds, which are aromatic with a smell similar to nutmeg. Nigella sativa is an invasive plant that retards the growth of other plants in the vicinity, particularly legumes.
Researchers at the South Carolina-based Immuno-Biology Laboratory in Hilton Head Island were the first to undertake a major study to examine Nigella sativa's ability to prevent and treat cancer. These scientists came to the conclusion that people with a robust immune system possess the aptitude to detect as well as eliminate carcinogenic cells even before the disease endangers the life of a patient. This is achieved by the immune system by encouraging enhanced immune cell production, in addition to production of bone marrow cells and B-cells which are responsible for producing antibodies. Black cumin or Nigella sativa is effective in this situation, as this herb encourages the activity of neutrophils, which are basically immune cells. Neutrophils live for a short duration and are generally present in our bone marrow. However, they become active when we develop any bacterial infection. It has been found that nigella extracts are also effective in stimulating interleukin production. This property of black cumin is similar to those of some other more esteemed herbs, including astragalus, cat's claw, garlic, ginseng and mistletoe.
