Zinc and Echinacea help to boost the immune system.
I have been playing NOT IT -- NOT IT for over a week. My granddaughter started it vomiting --could not keep anything down. Then my baby grandson, his Mom, his dad, my other son and the one I feel really bad about is my daughter's boyfriend. He works offshore and this was the first Christma he was home in 12 yrs. He was sooo looking forward to spending the day with family and ended up tossing his cookies all day and if it didn't come up it went straight through.
Just keep telling him NOT IT -- NOT IT.
