I can highly recommend ACV 1tbs and oregano oil 1 drop for a sore throat remedy. I put this in the back of my throat and lay back to coat the throat way back. I felt relief immediately. The problem came when I swallowed the mixture, as I had nothing in my stomach. So from my mistake I would recommend eating something first, or at least have some baking soda in water first so it can reason with the Apple Cider Vinegar when it hits. As it was my stomach was nauseous for the whole day, but my sore throat was gone! So the stomach nausea sent me back to earth clinic, which I love, to find another remedy (mint tea).
FYI my oregano oil is already diluted from manufacturer, I would be really careful if you had any full strength.
