Understanding the Benefits of Onions
Often, the worst part of colds and flu is the lingering cough. It can be frustrating, right? But did you know that onions are known to greatly benefit the respiratory system? Yes, they are! Making a simple onion poultice can provide relief for hours. Let’s dive into how you can create this soothing remedy at home.

How to Make an Onion Poultice
Here’s what you need to do:
Ingredients
1-2 onions, thinly sliced
Instructions
Steam the Onions: Start by steaming the onion slices until they are soft. If you don’t have a steamer, no worries! You can learn how to steam vegetables without one here.
Prepare the Poultice: Once the onions are steamed, remove them from the steamer and pat them dry.
Wrap the Onions: Place the onions in a clean dish towel. Allow them to cool until they are tolerable to the touch.
Apply the Poultice: For chest congestion and cough, place the poultice on your chest. If you’re dealing with deeper congestion, apply it to your back. Do what feels the most soothing for you!
Leave It On: Let the poultice sit in place until it cools down. You can repeat this process by steaming the onions a little longer and placing them back in the towel.
Why Onions Work
Onions contain compounds that can help reduce inflammation and fight infection. They are rich in antioxidants, which can support your immune system. Plus, the warmth from the poultice can help to soothe your chest and ease coughing. Isn’t that amazing?
Additional Tips for Relief
While the onion poultice is a fantastic remedy, there are other natural solutions you can explore:
Stay Hydrated
Drinking plenty of fluids is crucial when you're feeling under the weather. Herbal teas, broths, and water can help keep you hydrated and support your recovery.
Rest and Relaxation
Your body needs time to heal. Make sure to get plenty of rest. Cozy up with a good book or your favorite show, and let your body do its thing!
Essential Oils
Consider using essential oils like eucalyptus or peppermint. They can help open up your airways and provide additional relief from congestion.
