Healing Powers of Onion: Poultice, Cough Syrup & Plaster

Amazing Raw Organic Onions! The smellier the better. They have been used as medicine for centuries. A member of the allium family, onions are antibiotic and anti-inflammatory. They are high in flavonoids, especially quercetin, and contain powerful antioxidants.

Here are some of the most popular medicinal uses:

  • Acne
  • Arthritis
  • Congestion
  • Laryngitis
  • Headaches
  • Earaches
  • Toothaches (they actually prevent tooth decay)
  • Heart disease and clotting
  • Infection


How to make an onion poultice:

Chop the onion small (you may crush if you wish) The amount you use will depend on the area you are going to cover.  Put the onion in a square of cheesecloth and pull the corners up around it. Use a rubber band, or baggie tie to secure the corners or just tie them.  That’s it!


For severe acne, place the poultice on the puffed infected area and leave for 15 to 30 min. You may use the same poultice if you have other areas and want to move it around leaving it 15 to 30 minutes each area. When you are finished, throw it out to compost. You may do this up to 3X a day. Once a day due to time restriction will still make a big difference it will just take a bit longer for the acne to go away. Make a fresh poultice each “session”. Do not place a poultice in the refrigerator for later.

For arthritis place poultice on affected joint (area) for 15 to 30 min. 3X daily.

For headache place poultice on the forehead for 15 to 30 min. 3X daily.

For earaches place poultice directly over the outside of the ear. Timing is the same.

For toothache place the poultice inside the mouth on affected area. Timing is the same.

For a small infection, such as a hang nail you may apply the poultice and sleep with it overnight.


Yes, this is my hand just this morning. For the first time in many years I had a hangnail that got infected. I had let it go too long and “suddenly” (we all know how this goes) it was swollen, bright red and very sore. I had to stop and think about what remedy I should use. I poked the area where I thought there might be a bit of pus with a sterilized needle. All I got was a bubble of blood. So, I chose the onion poultice.  I used plastic cling wrap to hold it onto my finger and slept with it on. After the first night it wasn’t quite as red and sore. Last night was the second night and again it is better yet today. It actually is quite a bad infection. I will continue the poultice until it is gone.

*Update on this infected finger: I only used the onion poultice one more night. The onion soaks into your body and it keeps healing. Plus there is a point where your body will have a handle on it and keep the healing going, if your immune system is good. My finger, no matter how hard I scrubbed, smelled like onion for about a week after the 3rd poultice. It was completely healed in about 4 more days and I did nothing more to it during that time.

If you do this remedy and use plastic cling wrap to hold the poultice on, be sure not to wrap it too tight. You need to maintain normal blood flow.


How to make onion cough syrup:

Slice 2 or 3 medium sized onions and then chop them tiny. I will use my strawberry chopper. In a glass bowl place a layer of onion and then a layer of raw local honey. Alternate these layers until onion is gone. Cover the bowl and let set in refrigerator for 24 hours. It will make a syrup just like strawberries do. The syrup will keep in the refrigerator for about a week.


For congestion and laryngitis use the cough syrup. Dosage is 2 Tablespoons every 2 to 3 hours as needed.

Also for congestion, use an onion plaster.


How to make an onion plaster:

Quarter 3 or 4 large onions and steam them until soft. Use a slotted spoon and place them to one side of a square of cheesecloth 10″ X 10″ or smaller depending on patient size. Fold the cheesecloth over and fasten it closed by tying or pinning it. Let it cool slightly. The plaster must be very warm but cool enough as not to burn the skin. Place it on the patients chest and leave for 20-30 minutes.


Tip: I keep my husbands white tee shirts that he spills on or are no longer white enough for him to wear and I cut them up for poultices or plasters. They work just as well and you don’t have to use layers.


For cholesterol and heart disease eat plenty of good traditional onion soup made with fresh onions, organic, of course. The quercetin flavonoid in onions keeps cholesterol from sticking to the walls of blood vessels.

As a colon cancer preventative you should also eat plenty of onion soup. It is known to stimulate the good bifidobacteria and suppress harmful bacteria within the colon.

Final Tip: The areas you use the onion poultice and plaster on, will smell intensely like onion afterward, possibly for several days depending on saturation. Washing the area with warm soap and water will remove enough of the smell that others probably will not smell it when you are out and about. Well, as long as they keep their nose off the area. 🙂
