What are the benefits of aloevera juice. thank you. considering there is a huge trend of this new "vemma" drink ?

No magic: Useful topically. Like everything else, aloe vera has all kinds of nutrients that an advertiser can list. There's never been any real basis for claims that its internal use treats / prevents disease; a group from leeds (food & function) discusses the groundless hyping of aloe & others, there are others on the absence of any real evidence, & chinese claims of allergic hepatitis. It's your money.
