First I would like to talk about what onion syrup does: coughs and colds. Onion itself is anti-microbial and anti-inflammatory. It is not a cough suppressant as often described but it reduces the frequency and intensity of spasmodic and insistent lingering coughs. Personally I also feel like it warms and opens the pores to get the sickness out.
Cover sliced onions with honey in a bowl. I used half an onion and it was plenty! Let it sit in a warm environment for about 4 hours, stirring here and there. Over time you will see that the juices of the onion are coming out and mixing with the honey.
This is my onion stuff after 5-6 hours. I strained the onions and put the syrup in a glass jar and put it in the fridge. It will last about 5 days in there. That is why it’s important not to make too much!
You can also add garlic and/or ginger for an extra kick. If mixed with cayenne pepper it will help clear mucus.
You can take a sip of the syrup as needed. I felt fairly warm right after and I can imagine it’s a good idea to go to sleep and sweat the cold out. The syrup tastes sweet with an onion kick.
The leftover onions can be used for a nice bake or fry. I haven’t tried them yet. Just know they are sweet and not as spicy as they were originally.
Please let me know if you have more questions. I have a whole handout here about cold remedies and I would love to share these remedies with people interested!
