Is there a homeopathic therapy for sinusitis?

Sinus rinses: Sinus rinses (carefully measured and balanced) are helpful for many sinus problems, including sinusits. In case of a true bacterial sinusitis, antibiotics are certainly recommended.

Sinusitis: There are many remedies for sinusitis. But sinusitis is often a chronic, or repeated condition -- and thus requires homeopathic consultation to select the most effective remedy. Some remedies known to help sinusitis include kali bichromicum, mercurius vivus, causticum, and hepar sulphuricum. You could still need any of the thousands of other existing remedies, though.
