1. Rhubarb leaves
When it comes to the stalk of the rhubarb plant, you can heave a sigh of relief, as they are edible and will do you no harm. But we can’t say the same about rhubarb leaves. If eaten raw, they can be poisonous. In certain cases, it may even lead to difficulty breathing.
Those who ended up in the ER also experienced a burning sensation of the throat and mouth. According to New York City’s Mount Sinai Hospital, another side effect of consuming raw rhubarb leaves is seizures. Try to avoid them at all costs!
