I will examine some of the political pressures that might be holding back clinical research with human cancer patients, and will consider why drug companies may wish to suppress the use of black seed oil.
In two separate 2011 studies, Chinese researchers  and Saudi Arabian researchers  reviewed the scientific literature for the use of black seed oil (also called black cumin seed or Nigella sativa), with cancer.
 In a 2014 study, Turkish researchers reported how black seed oil could potentially be helpful to people receiving radiation treatment for cancer.
They indicated that many cancer patients treated with radiation therapy suffer severe side effects during and after their treatment.
This could improve the quality of life for cancer patients.
