symptoms of bad mushrooms
Gastrointestinal Irritants. The most frequent form of mushroom poisoning is caused by a wide variety of gastrointestinal irritants. The symptoms usually appear within 20 minutes to 4 hours of ingesting the mushrooms, and include nausea, vomiting, cramps, and diarrhea, which normally pass after the irritant had been expelled. Severe cases may require hospitalization. Supportive treatment may include attempts to eliminate the irritants.
