Do you eat lemon seeds

Lemon seeds do naturally contain salicyclic acid which is the main ingredient in Aspirin, though this is in small amounts. Other than that there is nothing present in large enough quantities to make lemon seeds inedible besides the possibility that the hard seed coat or the bitter/astringent chemicals inside the seed could cause digestive problems to some people. It would probably be best for a person to try to prevent eating the seeds but any accidental ingestion would not be harmful unless the person had an allergy or a medical condition that would be aggravated by ingestion of hard seeds such as irritable bowl syndrome or diverticulitis.
