I used to get a sinus infection with every cold I got. then I would take an antibiotic and it would go away. for the last 3 years, I have taken 2 drops of essential oil of eucalyptus directly on my tongue at the first sign of a cold. As a result, I have not had the sore throat and stuffy nose that usually came with my colds AND they have not turned into an infection. I haven't had any antibiotics in 3 years. I recommended this to my sister in law who suffered from the same ailments and she swears by it too.
