These symptoms are worse in a warm room and better in the open air. It is of little use after the cold is established. **Mercurius is similar, having rawness and soreness in the nose, but it is especially aggravated in damp weather.

This remedy alone will cure more sinusitis than any remedy because it is more often indicated. Thick, yellow, tenacious mucus in posterior nares, more distinctly yellow than **Kali bichromicum and profuse. If you have a **Pulsatilla cold, and in addition to it you have sneezing, give Cyclamen, also for attacks of sneezing without a cold.
