KOCHI: A 14-year-old girl and her grandmother suffered a severe case of poisoning after accidentally consuming datura leaves on Tuesday, as the latter mistook the weed for green spinach and used it to make a dish for lunch. Dr Bipin Jose, consultant, Pediatrics, Rajagiri Hospital, said the leaves of Datura Inoxia — commonly known as devil’s weed or ummam — are similar to green spinach in terms of shape.
