An insight into the botanical origins of propolis from permanent preservation and reforestation areas of southern Brazil

Abstract Brown propolis from permanent preservation and reforestation areas of southern Brazil have attracted international commercial interest and have a unique composition, although little is known about their botanical origins, which are the plant resins used by bee foragers to produce propolis....
