Onions: Complex and Healthy

The Germans love onions: almost 410,000 tons are harvested in Germany every year. The qualities of a flavor enhancer are not only appreciated by chefs. The food industry uses onions in the production of flavors for finished products. Onions are also used medicinally.

Onions as a home remedy for cough and inflammation

Onions are a proven home remedy for coughs because the sulfur compounds in the onions have an antibacterial effect. They also help loosen up mucus, making it thinner and easier to cough up. The leek plant developed these substances over millions of years as a defense against pathogens such as bacteria and viruses. Earaches and other inflammations can also be combated with onions. Onion ointment can support scar healing because it has a decongestant and anti-inflammatory effect. Experiments with bacterial cultures showed that the substances in the onion effectively combat various pathogens.

Onions in the fight against cancer?

Scientists at the Rostock University Hospital are researching whether onions can also help against cancer. Because the outer layers of the leek plant contain quercetin, a secondary plant substance that can specifically attack tumor cells. This could complement conventional cancer therapies in the future.
