Hi Tony. Thanks for your response. Apparently she used CS to treat her horse for Lyme disease, and was made aware somehow that her horse's selenium deficiency was a consequence of the CS. On our EPM list, many of us have used CS to treat our horses for EPM and none of us, to my knowledge, have had any problem with selenium deficiency. But that apparently is the result of our geographical areas containing sufficient selenium for replacement through grazing and forage consumption. I know that there are parts of this country that do not provide sufficient selenium -- I live in one. For this reason, I supplement my horses' diets with a selenium product. She must live in an area like mine, but is unaware of it and does not supplement selenium. But I was unaware of the relationship between CS and selenium, and I think that's valuable knowledge. MA
