Pomegranate fruit (Punica granatum) has been widely studied as a dietary
component that is an important source of biologically active compounds. Mainly in the
over the last ten years, much research has been done into what concerns the health
benefits of this fruit (peel, seeds and juice) producing encouraging results to prevent
and treat specific diseases such as obesity, diabetes, neurodegeneration and cancer.
Additionally, the use of pomegranate by traditional medicine as antidiarrheal, antihelminthic,
diuretic and digestive, has been also reported in ethnobotanical studies.
Pomegranate is described as containing a very high content of polyphenolic compounds
when compared to other fruits or vegetables, namely ellagitannins and hydrolysable
tannins and flavonoids (anthocyanins, flavones and isoflavones). These phytochemicals
have been identified for their many health benefits including its very high antioxidant
activity and anti-inflammatory, antitumor, antimicrobial activities, among others.
Considering that polyphenols have been widely reported to counteract the oxidative
stress effects in different model systems, this chapter will highlight the phytomedicinal
potential of pomegranate by describing its health impact and mechanisms of action in
oxidative stress-related conditions. In addition, its origin, production, consumption and
traditional uses will be briefly discussed and those related to its phytochemical
composition and health promoting properties, namely those related to its antioxidant
activity will be detailed.
The main focus will be the action of pomegranate in oxidative stress-related diseases,
including inflammatory processes, cancer, diabetes, cardiovascular diseases and
neurodegenerative disorders. Bioavailability aspects will also be presented.
