For years I suffered from severe sinus congestion. The pain and the headaches were at times unbearable. I tried every medication I could find but nothing worked for long. I even became addicted to nose spray. I have a high presser job and could not afford to be side tracked by this sinus problem. So I just suffered through it, doing the best that I could, resigned to the fact that this was a condition for life and I would have to live with it. A friend of mine at work saw me in a miserable state one day. I had a headache, my sinuses were completely blocked and I was feeling terrible. She sprayed a little of your eucalyptus liniment on the back of my neck and had me breath some of the eucalyptus vapors from a cotton ball. Almost immediately I could breathe better. A short time later my headache was gone. I was shocked. How could something this simple be so effective? I felt good the rest of the day. I bought a bottle and use it when needed and my sinuses are clear.
