This could be possible, there are people who are allergic to aloe amongst many other things.  Our experience is this is usually because of the specie & variety of the aloe; the processing or other ingredients added to the aloe.
Aloin, is a bitter irritant, found at the bottom of Emerald Aloe leaves.  The base of the leaf is cut off and disposed of.  The remaining gel is  hand rinsed to make sure you don’t have aloin in your Andra Sina Skincare or juice.  Many other aloes have aloin running through the whole leaf which causes skin irritation, diarrhea and cramps.
