"I have been able to 'bounce back' quickly many times after using Thieves Spray in my mouth. Not only have I found Thieves Spray to be effective for killing germs on surfaces, but it has also stopped the symptoms of a sore throat. I usually spray once and then as needed. Use with Thieves hard lozenges, and at night I highly recommend running a cold-air diffuser with Purification oil." Joy Glover
