Toxicity
The plant is inedible when raw and considered toxic due to the presence of calcium oxalate crystals, typically as raphides. The toxin is minimized by cooking, especially with a pinch of baking soda. It can also be reduced by steeping taro roots in cold water overnight. Calcium oxalate is highly insoluble and contributes to kidney stones. It has been recommended to take milk or other calcium rich foods with taro.
