Have you ever tried elderberry? I have a dear friend from my church back at college who is 64 and very much believes in using vitamins and herbs instead of vaccines and prescription medications. She takes elderberry anytime she is around people who are sick--she used to be a nurse.

"Elderberry is used for its antioxidant activity, to lower cholesterol, to improve vision, to boost the immune system, to improve heart health and for coughs, colds, flu, bacterial and viral infections and tonsilitis. Bioflavonoids and other proteins in the juice destroy the ability of cold and flu viruses to infect a cell. People with the flu who took elderberry juice reported less severe symptoms and felt better much faster than those who did not." -Quote taken from: http://www.herbwisdom.com/herb-elderberry.html
