General symptoms of poisoning:
Diarrhea, drowsiness, vomiting
Notes on poisoning:
Ingestion of a "handful" of berries caused repeated vomiting, green, watery diarrhea, and passage of green semisoft stools. The drowsiness might have been associated with the ipecac-induced vomiting. Ingestion of berries usually results in mild symptoms unless a lot of berries are eaten. Children are more likely to eat the berries (Rodrigues et al. 1984).
