CHP warns against eating wild plants
The Centre for Health Protection (CHP) is warning the public not to eat wild plants, after a woman was admitted to Ruttonjee Hospital on Saturday, after consuming calcium oxalate raphide - the stinging crystals in plants.  The woman, aged 51, developed oral and throat numbness shortly after eating, what she thought was, home-grown taro in Wan Chai.  The CHP said the woman had consumed giant alocasia, which looks like normal taro but contains calcium oxalte raphide. The CHP said the woman is now in a stable condition.
