Taking 1 T of elderberry syrup daily during flu season can help prevent or give a milder case by knocking viruses out before they can get a chance to make you sick. DH and I did that during swine flu in 2009, we still got it but he got a mild case, but I had stopped the elderberry because I got sick of it. And got a very bad case. I make my own pretty much likes Summerthyme's recipe.
Yes. Elderberry ( whether sambucol, my syrup recipe, or any other effective form)works by *stopping influenza viruses from reproducing.* It doesn't kill the virus. "Viral load" is the medical term for "how many live virus cells do you have in your system? " The higher the viral load, the sicker you feel, and the more likely you are to develop dangerous problems like cytokine storm.
We've found that we can take as little as 1 teaspoon of my syrup morning and evening for prophylaxis (prevention), and it works probably 99% of the time. (Lots of school teachers and corporate types who travel in flying germ capsules in our family).
If we do start to develop symptoms of flu, we immediately move to a minimum of 4x a day dosing. In the case of the dangerous H1N1 strain in 2009, we took it every 3 hours... and the one day I skipped two doses because I was calling hay, I got so sick I couldn't have gotten out of bed the next day if the house was on fire.
Early and often, and if someone is really ill, set the alarm and dose every 3 hours through the night, as well.
