What side effects this plant can have?
This plant can cause abdominal pain, diarrhea, dyspepsia, nausea, and the inhibition of bile secretion in humans. These adverse reactions often occur because the plant contains potent anthraquinone compounds that act as stimulant laxatives. When consumed in excess, these substances irritate the intestinal lining, leading to cramping and urgent bowel movements. The gastrointestinal distress frequently manifests as nausea or indigestion shortly after ingestion. Furthermore, the chemical constituents may interfere with normal digestive functions by inhibiting the secretion of bile from the gallbladder.
