Safety & Contraindications

Class 1. None reported. “Hazards and/or side effects not known for proper therapeutic dosages”. Raw unripe fruits and other parts contain the cyanogenic sambunigrin, which in excess, can cause diarrhea and/or vomiting. Excessive use of diuretics may result in hypokalemia. If antineuraminidase E activity of berry extracts can be confirmed, this might be viewed as a potential competitor for the new 1999 drug Relenza™. The berry extracts have long been recommended for flu.
