Hi foo d. While I can't provide you with a definitive answer on the actual product you received, your questions--and wife's reaction--prompted my reply.
Back in my dancing days, we alternated between the grand pursuits of ultimate thinness and ultimate healthiness. What I only later realized is that one of our "wonder fads" helped with both: the scadloads of aloe vera juice I consumed for a strong immune system--the 80's precursor to wheatgrass juice, I'm assuming--was purportedly a strong laxative remedy as well.

In any event, while aloe barbadensis (the scientific name for aloe, aloe vera, etc.) is widely known as having medicinal values, its benefits are not only topical. However, I can not imagine how you could end up with a palatable dessert (read: BLECH!) unless you used minimal amounts of aloe masked by maximum amounts sweet stuff!
Perhaps you could contact your folk at the market and they could clear up any confusion. If not, the International Aloe Science Council (look, I just read about these things!) might provide you with more insight. Their website (
http://www.iasc.org/ ) actually has an article on aloe's use as an ingredient versus as a drug.
Good luck!
