Onion Syrup for Cough and Flu

Onion is one of the most popular vegetables. It is grown almost all over the world. An unpleasant smell and sharp taste do not discourage eating raw onions. Why is it so widely used in cooking? 

After all, it is not only used for culinary purposes but also considered a cure for some diseases, including colds and flu. 

Onions have been present in the daily diet for millennia. For centuries it was also used in folk medicine, including as medicine for Rheumatoid Arthritis. It was also used for digestive problems, hypertension, excessive cholesterol, ulcers, and … hangover. However, due to its nutritional content, onion is used primarily as a remedy for colds. 

Onion is antibacterial and antiviral and contains minerals such as sulfur, magnesium, silicon, zinc, a vitamin C, which help strengthen the body’s resistance to cold and fule. 

So naturally, people use onion to make, and onion syrup has many health-promoting properties.

My family always had onion syrup in the pantry. In my house, we used to make all kinds of folk remedies. 

Most of us know the taste of onion syrup. The sweetness is mixed with the spicy flavor. Not everybody is a fan of the smell, though! I remember drinking onion syrup when I was a child, which is not a pleasant memory. However, we have been preparing onion syrup for generations to nip the cold in the bud. Onion syrup comes to the rescue as soon as a runny nose and cough appear. 

This natural cough reliever has been passed along from mom to mom, with different variations, for thousands of years. 

This onion syrup recipe contains germ-fighting, immune-stimulating garlic, anti-tussive onions, and anti-inflammatory ginger, proven ingredients for soothing and shortening colds and flu. Honey has antibacterial and antifungal properties and soothes a sore throat.

Onion syrup recipe

A simple recipe. The proportions of the ingredients are not very important. And there are only four ingredients: onions, garlic, ginger, and honey.

Onions, ginger, and garlic should be finely chopped or sliced and mixed with honey. Put a layer of onion in a mason jar, then add honey and a layer of the onion again, or combine the onion with honey. You can also add lemon juice to the mix for a vitamin C boost.

After about 5 hours, the onion will start to release the juice. Leave the syrup in a warm place for ten days. Store in the fridge for up to two months.

Onion syrup is an effective remedy for children’s cough, but it does not taste great! So my family used to add some mushed wild blueberries to make it taste better. Blueberries will give an additional boost of antioxidants to help us fight the cold. It tasted much better with blueberries, and the children weren’t so fussy eating it.
