Why can onions be effective?

Onions are known to offer a wide range of health benefits. They have high content of sulfuric compounds, like sulfoxides, thiosulfinates and cysteine sulfoxides. It is due to these compounds that you cry while cutting them and you enjoy their pungent flavor. Onions also have potent properties due to their thiosulfinates, which are shown to kill E.coli and salmonella. Sulfuric compounds in onions play a major role in preventing heart disease and cancer, due to which they become effective immune boosters. Onions are also rich in quercetin, an antioxidant that is helpful in fighting against free radicals, and boosting immune response. Onions are also helpful in breaking up or clearing mucous that might be blocking a person’s immune system. In addition to curing fevers, coughs and colds, onions are also found to be effective in dealing with a number of respiratory diseases.

How to use onions for curing colds

Follow these steps to use an onion to cure cold:

  1. Peel and cut an onion into thin slices, preferably a red onion. All onions are known to have medicinal properties to cure and treat colds, but red ones have highest quercetin content. Quercetin is a flavanoid rich in antioxidants, that are known to fight against free radicals and stop production of histamines.
  2. Place the sliced onion in a small bowl, and pour honey over it. Pour enough honey to coat all the onion slices properly. By doing this, you will minimize the severe heat and taste of the onions, and also add the healing powers of honey to it. Honey is also known to be a natural suppressant for coughs, as it also contains quercetin, the flavanoid.
  3. Put this bowl in the refrigerator and let it sit overnight. Eat this mixture the next morning. If there is any leftover honey, eat that too, as it is also infused with the healing properties of onions.
  4. Maximize the use of onions in your food. You can add raw onions in a variety of sandwiches, soups, salads, and even some sweet dishes.
