I traveled 10 hours to get home for a family wedding...only to be stricken with a terrible flu feeling in my stomach. My aunt offered me some of her Oscillococcinum and said I would feel better within the hour. I didn't really believe her, but what did I have to lose. The product is great tasting and easy to take. I only had 12 hours to feel better or I'd have to miss the wedding. Well, I actually felt better within the hour like she said. This was 10 years ago and I am still keeping this product, using this product, and recommending this product! I am thrilled that I can actually find this in normal stores now and not just at health stores!
