Can tomatoes be toxic?

Tomatoes, when eaten green, can be very toxic. The degree of toxicity depends on the degree of ripeness of the fruit.

When fully green, tomatoes can be as toxic as the tomato plant itself, a plant of the Nightshade family that is very poisonous.

As they begin to mature, they lose solanine, the toxic component, so that, if a little green, they can be a bit indigestible or even not to cause any problems.
