Aloe vera plant contains aloin, which has a laxative effect if consumed orally.
It is found on the interior part and the coating of the leaf. It is a yellowish color, and it is very bitter.
To avoid ingesting it, you should wash the leaf very well before cutting it. Also, wash the aloe vera gel once you extract it with the spoon.
Another piece of advice is to consume aloe vera diluted in water and never eat the gel alone, as it can cause kidney damage.
If you have liver, intestinal, heart, or electrolyte problems or take diabetes, diuretics, or laxative medication, talk with your doctor before consuming aloe vera juice.
