Whether or not eating raw cowpeas can be toxic varies according to the individual. For those with a good previous constitution and no obvious underlying or primary disease, taking small amounts of raw cowpeas will not result in poisoning. For those with poorer basal constitution, obvious primary diseases, and taking large quantities of raw cowpeas that have not been cooked, symptoms of poisoning can occur. First, the patient will exhibit digestive symptoms such as nausea, vomiting, acid reflux, heartburn, abdominal pain, and diarrhea, with colicky pain around the navel being particularly predominant. Patients may also experience mucopurulent, pus-like and blood-like stools, and dilute watery stools. This is followed by neurological symptoms such as dizziness, headache, and blurred vision. In severe cases, there will also be chest tightness, shortness of breath, and dyspnea. It is important to go to the hospital for treatment as soon as these clinical symptoms appear.
