My doctor’s advice: “Elderberry is the best anti-viral medicine there is, period.” This from a traditional M.D. He was right! It knocked out the flu for me when nothing else would. But it is not just for treating the flu – it can be taken as an immune boosting preventative too. If you want to be prepared for the flu season, get ready by starting your elderberry tincture now. It takes 6-8 weeks to prepare. Don’t worry, almost all of that time is just waiting! And it is really easy.
