Weez is traditionally used to soothe the chests of horses that have great difficulty with airborne particles in winter when dusty & in the summer when high pollen counts cause annoyance. Weez may only be needed for a relatively short 1 or 2 month period until maintenance on Pollene X/ Dust-X is possible.
