5 Ways Onions Can Help You Get Rid of a Cough

16 January, 2020
Onion is a common ingredient in traditional medicine for cough remedies. But, how effective is it? How can you use it? Today, we'll answer those questions and more.
 

Getting rid of a cough isn’t easy, but today we’ll share some home remedies that might help.

Coughing is one of your body’s defense mechanisms produced to fight viruses and bacteria or foreign objects in your airways.

It’s produced by an explosive emptying of the air in your lungs. And most of the time, it comes along with phlegm and irritation.

While it’s not advisable to stop it, because it’s one of the ways your body gets rid of excess mucus, many people are in search of a way to control it since it can be bothersome or painful.

To get the best and most effective treatment, you should always see your doctor first. They can suggest some medications that are appropriate for your situation and can make recommendations about lifestyle changes that might mitigate your symptoms.

As a complement to your doctor’s instructions, there are some home remedies that can help calm your cough. While they shouldn’t be your first line of defense, they can help in mild cases. Have you ever tried cough remedies with onion?

Home remedies with onion to get rid of a cough

These remedies are part of a whole catalog of traditional medicine that people have been sharing with each other for decades. That being said, it’s important to mention that we still don’t have sufficient scientific evidence to support the safety and effectiveness of onion for treating a cough.

There are a few small studies, like one from West Indian Medical Journal, that suggest that some mixes containing onion are effective against certain microorganisms associated with coughs, including Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa, and E. coli, among others.

 

So, it’s important to remember that these remedies can’t replace medical treatment, and can be ineffective. As we mentioned before, your first step in treating a cough is to see a doctor. If you have a mild cough, you might consider trying some of these remedies:

1. Onion garlic tea to get rid of a cough

2. Onion and honey cough syrup

Contrary to the case with onion, there is much more scientific research to support the positive effects of honey on a cough. In fact, a study in Pediatric Reports from the World Health Organization identifies honey as a potential demulcent for coughs.

This same study shows that honey has antimicrobial properties that have proven effective against microorganisms like Staphylococcus aureus and Streptococcus faecalis. Not only that, but it’s rich in free amino acids, vitamins, trace elements, and flavonoids.

 

Ingredients

  • 1 onion
  • 4 tablespoons of honey (100 g)

How do I make it?

  • Slice the onion finely and put into a glass jar.
  • Cover with the four tablespoons of honey and let it sit for 10 to 12 hours.
  • After this time, have two or three tablespoons of syrup a day.

3. Onion lemon juice to get rid of a cough
