Aloe Vera has long been considered a miracle aid as it can be beneficial for so many conditions and people report great benefits.
It can have side-effects however including diarrhea and abdominal cramps. It may interfere with medication too and is considered to be connected to electrolyte imbalances and dehydration as well. As such there are reports that for those who have ulcerative colitis or crohns,should not use Aloe Vera.
It works as a laxative which can also reduce the chances of your medication being absorbed.
Some sufferers with Crohns disease swear by it however, so it really is a personal decision as to whether to try it.
