Are lemon seed poisonous?What happens if you swallow a lemon seed?

Lemon seeds are not poisonous if ingested. However, they can have a bitter taste due to the presence of a substance called limonin, which is found in the seeds and rinds of citrus fruits. While they're not harmful, they aren't typically eaten because of their bitter taste and hard texture.

That being said, it's not recommended to consume large amounts of lemon seeds, or any fruit seeds for that matter, due to their potential to cause digestive issues if eaten in large quantities. But swallowing a lemon seed by accident should not cause any harm.

If you're juicing a lemon or preparing a dish that requires a lemon, you can remove the seeds before using it to avoid the bitter taste or any potential choking hazard, especially for children.
