9. Allergies
If you have an allergic reaction to any food or substance and it causes a skin rash, then no surprise: aloe vera can help. This is once again thanks to the anti-inflammatory properties as well as the mild analgesic (painkiller) effects which will help to soothe and calm the reaction.
I actually experienced this myself recently. At a party, I had an unusual reaction on my neck and had no idea where it came from. I tried applying a little aloe vera as my friends had a plant there and this immediately reduced the swelling and irritation.
