Can you please tell me what is the best herbal medicine for sinusitis?

I’ve been suffering for sinusitis for 2 and a half years. http://www.rockwellnutrition.com/

Take steam inhalation— Fill a bowl one-third full with hot water and add 3 to 5 drops of eucalyptus oil. Cover your head with a towel, lean over the bowl, and inhale the steam.
