Just mix together flour & mustard powder at a 4:1 ratio. I use 4 Tbsp flour & 1 Tbsp mustard, adding 1/4 cup of warm water. Place it in a kitchen towel, fold it up and apply to the chest area for up to 20 minutes (no longer!) Your congestion will begin to loosen & you will begin to breathe easier.
The mustard pack does warm your skin. This is not because the pack is hot to the touch, but the ingredients set off a chemical reaction that allows the mustard powder to penetrate the skin like a transdermal patch. Left on too long you can burn your skin.
I have done this for a couple of winters & it is a perfect remedy when you don’t have store bought medicine in the cupboard and you are too sick to leave the house. Take a shot of apple cider vinegar; followed by a glass of orange juice and you are on your way back to feeling like yourself. Stay healthy & keep hydrated!
