New Era Comb Q contains ferr phos, kali mur, kali sulph and nat mur. Ferr phos is traditionally used when irritation and heat are part of the early stage of a cold, kali mur is the tissue salt most often linked with thick white mucus, kali sulph is commonly used when congestion turns yellow and lingers, and nat mur is associated with watery discharge and sinus sensitivity.
That gives New Era Comb Q a clear place in the range. It is aimed at catarrh and sinus conditions where congestion can change from runny to blocked and back again. Biotin is also included, and biotin contributes to the maintenance of normal mucous membranes.
The useful thing about this blend is that it covers several mucus patterns rather than one. Nat mur suits the streaming phase, kali mur the blocked phase, and kali sulph the later stage when congestion hangs around. That is why it is often chosen for sinus complaints.
