My two LO's have the flu right now. I can't be certain it is the swine flu, because we haven't been to a doctor for the test, but it definitely is the flu (I've heard conflicting reports that swine flu is the only strain going around right now and I've heard that is the predominate strain of two that are currently circulating.) Both took Oscillococcinum as soon as symptoms started on Wednesday, as well as lots of sodium ascorbate. You would never know they were sick, except for longer than usual naps and a bit of a decrease in appetite!
We've all had the regular flu before and it wasn't pretty. This has been so mild--I was expecting worse with all the hype that has been reported in the media over the last several weeks.
My ds had the regular flu in January of this year and he used Oscillo for the first time and was shocked at the difference it made in how he felt and how soon he recovered as opposed to years past when he's taken nothing or Tamiflu (before we knew better!)
I would definitely recommend it based on our experience.
