Safety Notes

It is likely safe to use aloe vera on the skin. It may be safe to take aloe orally for a short time, but abdominal cramps and diarrhea are possible. Not enough studies have been done to say whether it is safe to use for a long period.
Interactions
Talk to your doctor about any supplements or therapy you would like to use. Aloe can interfere with treatment or make conditions worse such as:
  • Aloe is a laxative. It will make food, fluids, or medicine move through your bowels faster. It may make any medicines you take less effective.
  • People with diabetes should talk to their doctors before taking aloe. It may interact with their medicines.
