allyl sulfide

noun

: a chemical compound C₆H₁₀S with an odor resembling that of garlic that is found chiefly in members of the allium family (such as garlic and onion), that may be prepared synthetically, and that is often used as a flavoring agent

Garlic, onions and chives contain allyl sulfides, which may trigger and improve detoxification enzyme levels to inactivate carcinogens.

—Sandra Gordon, Chicago Sun-Times, 20 Oct. 1999

However, all of the ingredients used in artificial flavors are on the "Generally Recognized as Safe" list and are approved for use by the US Food and Drug Administration; unless you're planning to heist—and ingest—enormous quantities of allyl sulfide or benzaldehyde, you shouldn't worry too much about adverse side effects.
