Use of natural antioxidant compounds has gained popularity for their ability to quench their free radical to protect the human body against oxidative stress. Thymoquinone has shown promising activity against reactive oxygen species like superoxide anions and hydroxyl radicals and thus reducing their effects on the human body. The presence of quinone structure is the main reason for the anti-oxidative property shown by this compound. Thymoquinone also showed protection against several organs from oxidative damage by inducing several free radical-generating agents.('Thymoquinone and its therapeutic potentials', 2015)
