A member asked:

Why do we cry when we cut an onion?

A doctor has provided 1 answer
Dr. Heidi Fowler answered

Specializes in Psychiatry

Onions: When you cut onions they release a chemical irritant (synpropanethial-S-oxide) which stimulates tear production from the lachrymal glands. It is tearing up - not crying.
