Onions have been used in a variety of dishes, particularly Asian cuisine. In the world, onion is now the second most important horticultural crop after tomatoes.

There are quite a number of onion varieties: there’s the red, yellow, white and green. All have unique flavors ranging from mildly sweet to very strong. They can be eaten raw, cooked, fried, dried or roasted. In fact, one of my most favorite appetizers is onion rings. They are also most commonly used for dips, salads, soups, spreads, stir-fries and other dishes.

Onions are effective against certain bacteria including Bacillus subtilis, Salmonella, and E. coli. They also have a number of medicinal effects like treatments to colds, coughs, asthma, and it is also used to repel insect.

In other nations of the world, onions are also used to treat angina, coughs, bacterial infections and breathing problems. They are also great with bronchial spasms, cardiovascular problems and cancer prevention.
