Privet and Juniper wood

Hello,

Does anyone here have information about whether privet was ever used for the wooden cores of Korean and other Asian bows? I understand Privet (Chinese Privet) is very common China, Russia and Korea. It seems like a very springy and lightweight wood to me but I am not sure of its compression strength. I would also like to know if Koreans ever toom advantage of Juniper trees for bow making. I believe there is at least one species of Juniper in Korea but I am unaware of its properties. In America, Juniper was, as everybody knows, a favorite wood for sinew backed bows among Aboriginal people. Thank you for your time.
