Aloe vera, which is from the Aloaceae family, is a common houseplant. Aloes contain anthraquinone glycosides which are purgatives (medications that encourage bowel movements). When ingested, these glycosides are metabolized by intestinal bacteria forming compounds that increase mucus production and water in the colon. This can result in vomiting and diarrhea. Other clinical signs seen with aloe vera ingestion include depression, anorexia, changes in urine color, and rarely, tremors.
