Ok...so I had the lovely symptoms of a cold creeping up on me. You know what I mean-the stuffy nose and headache coupled with a draining fatigue. So, I busted out a cloth and poured 10 drops of Eucalyptus essential oil and 10 drops of Rosemary essential oil and kept breathing it in everywhere I went. I even took it to bed. They both opened me up and the Rosemary killed off the germs that causes infection. I also took on two classes of yoga and now it is gone before it even really started. Many people would've headed straight for the over the counter meds and would've experienced a full outbreak. So now you know the secret. Try it the next time you feel something creeping up on you. You'll be so glad that you did! PS-also pour 7-10 drops of Rosemary essential oil on a cloth and clean around areas that most people touch around the home like door knobs and such. This will keep things from spreading. Many blessings for a healthy day to you!
