Onion Poultice Benefits
I know you may be wondering if this folk remedy is actually an effective treatment.
Could this fragrant (some may say stinky) simple onion poultice be the best treatment to help loosen thick mucus, clear your lungs, and help you feel better?
Well, if you find yourself questioning the use of poultices, consider these science-supported health benefits of onions:
- they are high in vitamins and minerals, including the antioxidant quercetin which can help boost the immune response
- onions have a high sulphur content and have been found to have anti-bacterial properties (here is a short interesting article about a 1,000-year-old onion and garlic remedy that astonished researchers!)
- these little bulbs have been found to have anti-inflammatory properties too!
There are many other health benefits associated with onions as well, along with having medicinal properties, they can help to balance blood sugar levels, aid digestion, reduce the risk of certain cancers, and so much more!
It’s easy to see how medical care has included the use of onions since ancient times!

How To Make An Onion Poultice
There are a few methods of making a warm compress, but I’ll share the way that my great-grandmother passed on to my mom and she passed on to me ๐
Onion Poultice Supplies
- 2 small-medium yellow or white onions (can add a few cloves of garlic for extra benefit!)
- 2 medium towels
- hot water bottle or heating pad
What To Do
- Slice or chop the raw onion (and garlic if you’re adding it)
- In a frying pan, fry the onions gently until soft (you can add a little water or olive oil if desired)
- Remove the onion slices from the frying pan and place them in a cloth approximately the size of the person’s chest.
- Place the folded towel (with onions inside) on the affected area and put second towel over the top of the warm poultice. Be sure the poultice is hot, but not so hot as to burn. If the person is feeling tightness in the back more than the chest, then apply it over the upper back. This can also be used on the outside of the ear for ear infections.
- Place a hot water bottle or heating pad over the top of the poultice to maintain heat. If the extra heat becomes uncomfortable feel free to remove it.
- Rest with the poultice on for at least 20 minutes.
Repeat this process twice per day or until there is relief!
Helpful Onion Poultice Tips
An onion poultice is really simple to make but here are a few tips to keep in mind:
- Use old towels- the onion smell is really strong and can take a few washes to remove all of the odor!
- Tie up the ends- if you’re afraid the poultice will make a mess or are using this for a child you may want to put the onions on the towel and use a rubber band to tie up the ends and then place it on the chest.
- Use the second towel that is placed on top as a little tent for your nose- this way you can breathe in warm air much like an herbal steam or a warm shower and it can help soothe a cough and irritated airways.
- Use this moist concoction before bed to help calm the cough so you can get some much-needed rest!
- Pair the use of the onion poultice with fermented garlic and honey or fire cider to help boost your immune system and feel better fast!

FAQ’S About Onion Poultice
Still have a few lingering questions about onion poultices? Let me see if I can help ๐
1. Do onion poultices actually work?
Onion poultices can provide real benefit if you’re plagued with a cough, chest congestion, respiratory infection, or other health issues that involve mucus and tight breathing.
An onion poultice can help by improving circulation and blood flow, thin and loosen mucus and draw it out of the body, and according to the National Onion Association, onions can also help promote a healthy gut, build immunity, fight infection, and reduce inflammation.
Pretty impressive, right?
2. Are onion poultices safe for kids?
They can be. It really depends on the age of the child and their willingness to sit with onions on their chest. Since an onion poultice is quite warm, it may not be comfortable for young children.
The good news is that there are other helpful natural remedies that could be considered for a chest cold or cough suppressant such as:
- putting onions on the soles of the feet
- warm water with a little raw honey (honey has been found to be as effective as cough syrup!)
- onion syrup or other homemade cough syrup
- herbal tea
- salt water nasal rinse
- Himalayan salt inhaler
*Not all of the suggestions above will be appropriate for every child, especially a small child. Also, babies under a year of age should not be given honey. And as always, please remember- if your little one isn’t feeling well it’s always a good idea to consult your health care provider.
3. Do onions have other helpful uses?
They actually do! In addition to having antioxidant and antiviral properties, turns out there are other benefits to onions that may not be as well known.
For instance, we have successfully used onion slices for bee stings and have found almost immediate benefit. Just slice and apply. In just a few minutes the stinging and swelling are reduced.
It may seem kind of weird, but between onion poultices, onion syrup, and relief from bug bites and stings, it is clear that for many, onions can be a huge part of a health and wellness lifestyle!

Can you use a heating pad instead of hot water bottle?
Hi Pj,
You definitely could use a heating pad if that’s what you have or prefer.
My son has had a horrible, lingering cough at night as a result of a cold. The past 2 nights have been awful for him, and as soon as he got in bed tonight the coughing fits ensued. I consulted Be Your Own Doctor, by Rachel Weaver, which mentioned this as an effective method, although she uses a 2:1 ratio of onion to salt, microwaving the two. I also rubbed his chest with olive oil before applying the poultice, and held it all together on his torso with a neck gaitor/buff (he’s young and it fits!). Literally as soon as I applied this his coughing CEASED! I have only heard him cough once in the past 3 hours, so this blows my mind! It works!!!
Hi Sarah,
Thanks so much for sharing your experience. I’m so glad an onion poultice helped your son’s coughing! And thanks for sharing the book info, I’ve never heard of that one but will definitely be checking it out very soon.
Hope you and your son have a quiet, restful night’s sleep ๐
I have used onions for years for bronchitis. I slice an onion, lay it on my bare chest, cover with cheese cloth and a hot pad and go to sleep. When I wake up the pressure is gone, I feel great. The onion pulls the junk out of my chest, and I can get back to life.
Thanks for sharing! I love hearing how other people use traditional remedies ๐
I have been sick for 13 days, green phlegm for 5 days , bronchitis ! I tried the onion poultice last night and I had the best night sleep in 13 days ! I have had bronchitis since I am a child ! And my mom suggested an old remedy my grandfather used to use ! I am so relieved I gave it a try ! I slept with it through the night ! I usually have coughing attacks at night with bronchitis ! Not even once !!! This will be the new normal for me ! ๐๐
Hi Brigitte,
So glad to hear that you are feeling better and this old remedy worked for you! Thanks so much for sharing your experience ๐
Lying here with an onion poultice as I type this. Never tried this before, but Iโve been so sick the past two days, and Iโve had to use my rescue inhaler so many times, Iโm about to use it all up! So I decided to try this. Iโm still wheezing a little bit, but I felt almost instant relief from the awful tightness in my chest. I have had a very non-productive, dry cough, and just now I actually coughed and felt like some of that gunk in there is lining up a bit. Iโm going to leave this on for a while and then Iโll probably do another before bedtime. So far it seems to be working wonderfully!! ๐
Hi Michelle,
Thanks for sharing your insight and experience. I’m so glad to hear that you tried the onion poultice and it is helping. I hope you feel better very soon!
When I was little, Mom made onions cough syrup. With 5 kids and when pharmacies weren’t on every block, home remedies were the only “medicines” most people knew. But Mom chopped onions into a container with a lid, then sprinkled sugar on and stirred it around. When the sugar was dissolved, the onions made their own “syrup”. This was left on the nightstand and we could just sip it as needed….. and there was no overdose possible. It was just onions, after all. And that was our family cough syrup until the mid 1970s. But I’m going to try the poultice for my annoying allergy cough. Thanks for the info.
Hello!
Thank you for sharing your mom’s recipe. I love hearing about people’s experiences with natural remedies!
Good luck with the onion poultice, I hope it helps relieve your allergy cough.
