Do-It-Yourself Onion Cough Syrup


If you’re concerned about the safety of over-the-counter cough syrups, you’re not alone.

So here is my simple solution for you and yours during this wintery, sore-throat, cough, cold, and flu season.

My DIY Onion Cough Syrup is a wonderful anti-microbial syrup to soothe coughs and sore throats.  It is useful on its own or as a base for adding other tinctures.  I keep some on hand for the cold and flu season and often add other herbs to make a medicinal cough treatment. It’s very easy to make and great for adults as well as children. Give it a try this season!


  • Slice one medium onion thinly
  • Using one cup of sugar, create layers of onion/sugar/onion/sugar in a large glass jar.
  • Allow to sit for two days.
  • Strain out onion.
  • Bottle the remaining mixture in an amber jar.
  • Store in a cool place (cool cupboard or fridge).
  • Use ½ to 1 tsp 3x/day for cough.

To make medicinal syrups for flu or lung conditions, add thyme, licorice, andrographis, echinacea, wild cherry bark, or mullein.  Add equal parts tincture to syrup (ie:  10mL tincture + 10mL syrup) for best results.
