Cassia occidentalis poisoning causes fatal coma in children in western Uttar Pradesh

We investigated cases of the annual seasonal outbreaks of acute hepato-myo-encephalopathy in young children in western Uttar Pradesh for causal association with Cassia occidentalis poisoning, by a prospective survey in 2006. During September-October homes of 10 consecutive cases were visited and history of eating Cassia beans was obtained in all. Nine children died within 4-5 days. There appears to be an etiological association between consumption of Cassia occidentalis beans and acute hepato-myo-encephalopathy.
