star anise

Atlanta, April 22, 2009 -- With bird flu, also known as avian flu, now confirmed to have mutated into a form that can be transmitted human-to-human, international disease control agencies are concerned by a new report that virtually all of this year's star anise crop, a vital component of Tamiflu grown only in four provinces of China, has been wiped out in a series of mudslides brought on by unseasonably strong tropical storms in the region.
