Fungus can be a serious health issue and should be treated from the inside out. External treatments give only temporary results. If you horse has fungus on the outside there is also fungus overgrowth internally! Fungus can attack your horse's immune system and cause a variety of symptoms. The use of anti-biotics is a major cause of fungus overgrowth in and on the body. They destroy all the healthy intestinal flora and this in turn causes the fungus to thrive and get out of control. Sugar, or molasses which is in most complete feeds will also cause the fungus to thrive. Fungus Secret is loaded with all natural ingredients that will make the fungus disappear!
