Pros: Works quickly
Cons: Need to take it immediately after being exposed to the flu or right after symptoms start to appear
Oscillococcinum is a combination of homeopathic remedies that is used to fight off and treat the symptoms of the flu. It also comes in a children's dose. It worked great when I took it immediately at the onset of symptoms. It also worked in preventing other people from getting the flu when they took it as soon as I came down with symptoms. But, when I got the flu and couldn't get any until few days into it, I didn't find it to be very effective at reducing my symptoms. It did seem to lessen the amount of time I was ill in comparison to other people who had the flu.
