FESS Nasal & Sinus Wash Extra Strength sachets are deep penetrating, preservative free non-medicated hypertonic saline wash to relieve nasal and sinus congestion due to allergies, hayfever, sinusitis, colds and flu. When mixed with warm water, the contents of each sachet will produce a 200mL saline wash.
The hypertonic solution (ie. more concentrated) draws mucous from the sinuses to relieve sinus pressure.
