Honey is also anti viral and will kill pneumonia virus. I keep honey and apple cider vinegar mixed up half/half in a jar. I just keep it in the cabinet, no refrigeration. First sign of a sore throat, I put some in a small glass and top with water. I sip on it until it's gone and keep drinking it until the sore throat or cold is gone. It is also the cure for food poisoning and diarrhea. If you are "running at both ends" so to speak, sip on ACV and honey. Even if you puke it back up, keep sipping on it until you have consumed about 1/3 to 1/2 cup of ACV and honey. In about 30 minutes to an hour, you'll feel much much better.
