Must be processed before use as raw Ban Xia is toxic. Ingesting the raw form can cause severe irritation of the mouth, pharynx, and gastrointestinal tracts, and has toxic effects on the nervous system. Symptoms of toxicity include a dry mouth, numbness of the tongue, gastric discomfort, burning sensations and swelling of the mouth, tongue, throat and salivation. In serious cases ingesting Ban Xia can result in hoarseness, spasms, dyspnoea and asphyxia.
