Colon Cancer: In a study conducted on animals, black seeds were found to fight against colon cancer in mice without having some adverse effects. According to cell studies, black seeds have anti-cancer properties; it specifically inhibits the growth of colon cancer cells.
Type 2 Diabetes: Experts claim that taking 2 grams of black seed daily could result to decreased blood glucose levels, increased beta-cell function in the pancreas, and decreased resistance to insulin.
Cognitive Function: One research study of forty healthy adult individuals revealed that taking one gram of Nigella sativa a day could help enhance cognitive performance, memory, and attention without having any side effects. Animal studies also show that there’s a possible link between Nigella sativa and enhanced brain function. Based on these findings, experts suggest the need for further studies regarding the effectiveness of Nigella sativa in preventing and slowing the progression of Alzheimer’s disease.
Epilepsy: A study published in Medical Science Monitor reported that black seed has anti-convulsive properties; it is effective in reducing the incidence of seizures in children who are resistant in conventional treatment.
Allergies: Results in a double-blind, placebo-controlled trial revealed that Nigella sativa is beneficial for individuals who are suffering from allergic rhinitis since it reduces nasal congestion and itching, sneezing, and runny nose.

Mechanism of Action
Thymoquinone extract from Nigella sativa was known to have antioxidant effects, and has hepatoprotective effects since it has the ability to restore the levels of glutathione, lactate dehydrogenase, and SOD. A study in rats suggest that nigellone, a constituent of crude extract of Nigella sativa seeds can reduce symptoms of allergy in human beings by inhibiting the release of histamine from peritoneal mast cells. Nigella sativa decreases smooth muscle contractions and reduces hypertension secondary to diuretic effects. Studies also show that Nigella sativa can also inhibit lipoxygenase and cyclooxygenase, thus acting as an anti-inflammatory agent.
Studies show that thymoquinone could decrease the likelihood of stomach tumors. Its mechanism of action includes promotion of cell death by inhibiting cell growth and inhibiting DNA synthesis. It is debatable if Nigella sativa could reduce the effects of radiation therapy, however, its antioxidant effects could prevent tissue damage following radiation therapy.
