The curry tree, Murraya koenigii or Bergera koenigii, is a tropical and sub-tropicaltree in the family Rutaceae (the rue family, which includes rue, citrus, and satinwood), native to Asia.[4] The plant is also sometimes called sweet neem, though M. koenigii is in a different family to neem, Azadirachta indica, which is in the related family Meliaceae.
