Wild taro stalks may contain toxins that may cause symptoms if ingested. Taro stalks contain ingredients such as calcium oxalate, aluminum oxalate, potassium oxalate, etc. These substances may cause health effects when excessive intake. At the same time, taro stems also contain a substance called taroside, which is a plant base glycoside that is toxic and can be hydrolyzed into hydrocyanic acid and formaldehyde.

Therefore, before consumption, it is best to cook or pickle wild taro stalks to reduce their oxalic acid content and toxicity. If you develop symptoms after accidentally eating wild taro stalks, you should seek medical advice immediately and inform your doctor of the possible ingredients.
