Since ancient times, pomegranate has been used for medicinal purposes. Know as "natures power fruit", the pomegranate is one of the most antioxidant rich foods in the world.
Native to the Middle East, pomegranates (Punica granatum), like most fruits, are rich in vitamin C, fiber, and potassium. What makes the pomegranate stand out though is its remarkable levels of antioxidants and inflammation suppressing phytonutrients. Researchers have identified more than 120 different phytochemicals in pomegranates with a study in 2008 finding the juice to have greater antioxidant capacity than even red wine, green tea, and acai berry juice. The most exciting research to date has come from studies on the pressed juice and a compound in it called Ellagitannins and their potential to exert antioxidant and anti-inflammatory effects on cancer cells. While more research is needed to make a definitive claim on the juice against cancer, research carried out in 2006 stated the juice to be a possible "nontoxic option for prevention or delay of prostate carcinogenesis."
Again when something has a long standing historical use, tastes great, and has no (known) toxic effects then it makes sense to include it in your daily regime.
When choosing the juice make sure to get 100% percent juice, otherwise you are paying for added water and sugar and diluting/negating most of the benefits to be had from the fresh juice. A great brand to look for is 'Biona Pomegranate Juice'. The juice tastes great alone or can be added to sparkling water, freshly pressed juices, and blended smoothies.
