Black cumin seed oil has been suggested as an adjuvant therapy in cancer treatment due to the properties of its bioactive antioxidant component: the thymoquinone (TQ). Doxorubicin cardiotoxicity is caused by increased oxidative stress that induces toxic damage to the cardiac cells. TQ does not diminish doxorubicin’s effectiveness as it does not alter plasma levels of the drug, but it does prevent its cardiotoxicity by reducing the production of oxygen-free radicals (ROS) that are deemed responsible of the doxorubicin-induced cardiomyopathy3. Other studies even found how TQ could even improve the anti-tumor properties of doxorubicin in some specific cancer cell lines4.
