Here is my homemade cough medicine recipe. I make a quart jar of this every year and we go through it in about 3 months. It will keep nearly forever at room temperature. I find that it feels good on a sore throat if it is heated up before administering.
We also take it dissolved in hot tea, its delicious!
2 tablespoons apple cider vinegar ( Bragg’s is great)
2 tablespoons honey (local raw honey is best)
2 tablespoons water
1/4 teaspoon cayenne pepper (add 1/2 tsp if you can stand it, its good for you!)
1 teaspoon grated, fresh ginger. Peel first.
Mix well, store in a tightly covered jar at room temp. Use a teaspoon at a time, as needed, for cough and/or sore throat. It might be too hot for small children so reduce the hot pepper accordingly.
