Aloe vera gel is actually safe to eat, and it also comes with multiple health benefits. Apart from the gel, the skin of the plant’s leaves is also safe to consume. However, if you’re thinking of eating the skin, be sure to wash it well beforehand since it may have been touched by dirt or pesticides.  Although the gel and skin of the plant’s leaves are edible, the latex layer isn’t. It contains aloin, a harmful chemical that can cause diarrhea and an upset stomach. Although a gram or two won’t do much, eating a significant amount of the latex layer can be very dangerous.
