A little-known raw material used in the most widely used antiviral flu medicine comes from the fruit of trees native to China. It turns out it also comes from pine trees in Maine’s backyard.Researchers at the University of Maine say they’ve found a new and relatively easy way to extract shikimic acid – a key ingredient in the drug Tamiflu – from pine tree needles.It remains to be seen if the process can be applied commercially. The major source now is the star anise fruit.
