Horses and ponies suffering from Post Viral Syndrome and Papova Virus should be considered candidates for Corpet (Coriolus versicolor) supplementation:
Coriolus versicolor supplementation has demonstrated an ability to increase white cell count in horses; thereby reducing fatigue in horses with PVS. Furthermore, Coriolus versicolor has been successful in reducing the size of sarcoids that are active. However, Coriolus versicolor supplementation has limited success when the sarcoids are dormant.
