Anon, skip the animal version of the IVC. Perhaps useful in an absolute emergency but you should be able to get the IVC now but if unable, zStack is what you're looking for as Dr. Zelenko put the right doeses of quercitin (ionesphore just like HVQ, IVC) Zinc, Vitamin C and Vitamin D3. The Zelenko Protocol. Hope your Mother gets better!!!
