Yes! I think it's pretty clear that Aloe vera is actually medicine. Maybe not for everybody, but when it works it's great.
It strikes me as informative that true Aloe vera is actually incapable of setting viable seed, thus of growing true from seed. It can only be propagated from offsets. This feature (and the lack of variation among cultivated plants) probably has to do with its domestication over the course of four millennia. Which was not due to human interest in ornamental horticulture, I can promise you.
