A staple food in most households, onions are used to add flavor to an otherwise bland dish and turn an average meal into an elegant dinner. However, onions have other uses beyond the kitchen.

Women, in many countries around the world, have used onion to regulate their fertility dating as far back as 3500 BC. The onion bulb has been documented as being eaten with the intention of encouraging menstruation in countries such as Europe, India, and Vietnam.
