Ingredient in some superfood smoothies (4)

I believe the answer is:

aloe

(Other definitions for aloe that I've seen before include "O, ale with bitter plant" , "Succulent plant (may be bitter!)" , "Genus of bitter herbs" , "Fleshy-leaved plant" , "Bitter drug from a leaf juice" .)

I've seen this clue in the LA Times.
